Acid rain is rain or any other form of precipitation that is unusually acidic. It can have harmful effects on plants, aquatic animals, and infrastructure through the process of wet deposition. Acid rain is caused by emissions of compounds of ammonium, carbon, nitrogen, and sulfur which react with the water molecules in the atmosphere to produce acids. Governments have made efforts since the 1970s to reduce the production of sulfuric oxides into the Earth's atmosphere with positive results Since the Industrial Revolution, emissions of sulfur dioxide and nitrogen oxides to the atmosphere have increased.[2][3] In 1852, Robert Angus Smith was the first to show the relationship between acid
challenges are making conservation a struggle. Climate Change Affects Biodiversity · The World Resources Institute reports that there is a link between biodiversity and climate change. Rapid global warming can affect an ecosystems chances to adapt naturally. What have governments around the world been trying to do about it? Climate Change Flexibility Mechanisms · Flexibility mechanisms were defined in the Kyoto Protocol as different ways to achieve emissions reduction as part of the effort to address climate change issues. These fall into the following categories: Emissions Trading, Joint Implementation and Clean Development Mechanism. · However, these have been highly controversial as they were mainly included on strong US insistence and to keep the US in the treaty (even though the US eventually pulled out). Some of the mechanisms face criticism for not actually leading to a reduction in emissions, for example.

when you're out at work or school all day etc. Although it may not be obvious, there is a connection between energy use and the environment. As the same with recycling; when you consume less power, you reduce the amount of toxic fumes released by power plants, conserve the earth’s natural resources and protect ecosystems from destruction. Although, individual consumers can’t solely be blamed for our rising global temperatures, since most of the world’s greenhouse gas emissions can be traced back to large companies. But people want to feel like they’re doing something, no matter how small, to prevent the worst-case climate catastrophe scenario from unfolding. After all, the only thing that has ever helped to change and protect the world, are us, humans.
Acid rain= damaged buildings=claims on insurance = less money for insurance company and there for effecting the economy. Political effects Acid rain can cause political tension between countries, good example is Canada and Usa. The goverment has to make öaws to battle the gasses for example taxing factories for using gasses. Bad faming= less expore Solutions Clean the smoke coming from smoke stacks on factories using scrubbers Design cars that make cleaner emissions Use less fossil fuels, such as coal, for power. The problem is that nuclear power, hydropower and coal are the cheapest forms of enery today. But adcancements in techonologies might change this in the future. Use more alternative energy sources such as wind and solar power Wind and solar powerstations are expensive to build. Create goverment regulations such as limiting car and factory emissions When the goverment would limit car emissions,
Also, as in any other agricultural production, biofuels can cause erosion and eutrophication due to fertilizer runoffs (Rajagopal, Zilberman, 2007). According to the International Energy Agency Report (2007), the fossil energy balance for different biofuels varies greatly, depending on the feedstock productivity, production and conversion technologies. For Margit Tepner k0848752 example, using coal in the production processes can worsen the GHG emissions significantly (Menichetti et. al.,2009). Figure 9. Percentage of GHG savings (Menichetti, 2009). Among the studies on biofuels ability to reduce GHG emissions, there is a great range. Besides balancing the fossil energy ration in the production process, clearing land for biofuels feedstock production will release significant amounts for GHG emissions. Soil and plant mass are the largest active stores of carbon on the Earth. Converting native habitats to

Mr Bush, while talking yesterday about a "new approach" and "a historic undertaking", remains totally opposed. *"It was a total charade and has been exposed as a charade," the diplomat said. "I have never heard a more humiliating speech by a major leader. He [Mr Bush] was trying to present himself as a leader while showing no sign of leadership.

dioxin (2,3,7,8 TCDD) is considered the most toxic. · PCBs were produced commercially in large quantities until production was stopped in 1977. . Emission sources Dioxins are mainly produced as unwanted byproducts of industrial processes and there is no intentional production or use. They can also to a small extent be formed naturally in forest fires or volcanic activity. Examples of activities resulting in dioxin emissions are waste incineration, burning fuels (wood, coal or oil), chlorine bleaching of pulp and paper and chlorinated pesticides manufacturing. Burning of many materials containing chlorine, such as plastics and wood treated with pentachlorophenol also produce dioxins. According to a study in the context of the Stockholm Convention, the main sources for emissions of dioxins to air in EU25 are Residential combustion (~ 30%) Open burning of waste (backyard burning) (~15%)

atmosphere, which causes the damaging of the environment, human health and the quality of life. Firstly, we should use green methods of powering like wind energy and landfill gas energy. This would reduce the amount of harmful gases. Another useful suggestion would be to plant trees. In this way we can increase the source of breathable oxygen. Unfortunately, many companies are contributing to deforestation. Finally, it would help if we put taxes on carbon emissions or higher taxes on gasoline. In this way people and companies will have greater incentives to conserve energy and pollute less. In conclusion, there are many ways to pollute the air less. We all have to do whatever we can to solve this major problem. As Shimon Peres said “If a problem has no solution, it may not be a problem.”

KLIIMASOOJENEMINE JA VÕITLUS SELLE VASTU Referaat Tallinn 2018 SISSEJUHATUS Käesoleva referaadi teema on kliimasoojenemine ja võitlus selle vastu. Teema valiku tingis huvi probleemi vastu, sest olukorda mõistavad kõik aga meedia kajastus on vähenenud samal ajal ilma, et oleks kõlama jäänud mõni kindel lahendus või märk paranemisest. Samuti soov teada, millised on tuleviku prognoosid ja milline on reaalne olukord maailmas. Teema tundus meie jaoks aktuaalne, sest iga päev aina rohkem tegureid mõjutavad meie elu Maal ning lisaks vanusega on tulnud ka teadlikkus, et teema mõjutab meie põlvkonda kõige enam. Miskipärast on probleem jäänud muude konfliktide kõrval taha plaanile ja leiab väga minimaalset kajastust meie igapäeva eludes ja meedias. See jällegi ei tähenda, et probleem oleks iseenesest lahenenud ja seetõttu jagasime me rühmaliikmete vahel ära aspektid, mis mõjutavad kliimasoojenemi...
corrode certain materials. As acid lands on buildings (especially those constructed with limestone) it reacts with minerals in the stones sometimes causing it to disintegrate and wash away. Acid deposition can also corrode modern buildings, cars, railroad tracks, airplanes, steel bridges, and pipes above and below ground. What's Being Done? Because of these problems and the adverse effects air pollution has on human health, a number of steps are being taken to reduce sulfur and nitrogen emissions. Most notably, many governments are now requiring energy producers to clean smoke stacks by using scrubbers which trap pollutants before they are released into the atmosphere and catalytic converters in cars to reduce their emissions. Additionally, alternative energy sources are gaining more prominence today and funding is being given to the restoration of ecosystems damaged by acid rain worldwide.

Building them up and pulling them down needs a lot of energy and about 30% of building energy is spent on it. It is thought that if in Tokyo 50% of all roofs are green it will save 1 million dollars a day of Tokyo businesses in cooling costs. Street light use 5% of energy, but it can be reduced to 2%. Usual TVs should be replaced with Plasma TV, because it saves energy more. By driving electic-car, it is possible to save energy about 20% and reduce global emissions. Carbon dioxide is used to grow tomatoes. Tomatoes which are eaten, have come out straight of exhaust of engine and gas turbine burning gas. But still this carbon dioxide finds its way to atmosphere through our bodies. It is possible to save energy if you isolate your freezers what freezes fish. Then you can reduce your freexing temperature. Deserts would be amazing places to storage sunlight energy. But to do this, we have to forget AC, because we need DC lines. If
without sacrificing growth by investing in pollution-control technologies. They made new laws. It was the start of "Japan's Pollution Diet". Today, Japanese cities are among the world's least polluted, according to the World Health Organization. Air pollution in Japan The air pollution is different in different seasons. During the winter air pollution in Japan is particularly bad since the polluted air comes not only from industrial and vehicle emissions within Japan, but also from polluted air masses that are derived from China. In the spring, the wind regime in Japan becomes less dominated by air masses blown in from China and thus air pollution in Japan begins to drop in most areas, except in the Kanto Plain district. Air pollution in Japan There is normally low to medium levels of air pollution in Japan in the summer. However, if there's no wind, you're likely to get a build up of smog if you're located in a valley.
To: Environmental protection agency From: Subject: Wind power versus oil shale Date: September 22 Wind power vs oil shale Introduction The purpose of this report is to analyse if wind power is better than power which is produced from oil shale. The report is based on EWPA (Estonian Wind Power Association) article which is published on their web page. Wind power It is said that the wind power is the most expensive source of power, but this statement is not plausible, because the recourse -wind- is for free. Calculations have shown that if new oil shale blocks were built, it would cost 3473 million EEK in a year per capita. On the other hand, if wind power were renewed in similar amount, it would cost only 868 million EEK per capita in a year. It means that if the wind power were renewed, it would be 17 370 millions EEK cheaper. The fact that wind energy saves resources and produces neither dangerous ...
to share with several people the cost of a trip he would do anyway. The expenses to be divided basically include the fuel and possible tolls. Let me introduce to you good points of carpooling: Firstly. by having more people using one vehicle, carpooling reduces each person's travel costs such as fuel costs, tolls, and the stress of driving. Secondly, carpooling is also a more environmentally friendly way to travel. Please pay attention, that sharing journeys reduces carbon emissions, traffic congestion on the roads, and the need for parking spaces. What do you think about problems with parking places? It is really hard to find parking place near our university. In our days, when the Internet could be used not only from a computer, it has greatly helped carpooling to expand, enabling people to offer and find rides thanks to easy-to-use and reliable online transport marketplaces. These websites are commonly used for one-off long-distance journeys with high fuel costs

When the wind blows, then it carries the pollution with him. Futhermore, the rain reduces the pollution. Air pollutants such as ozone, nitrogen oxides, and sulphur dioxide also have harmful effects on natural ecosystem. A clean air supply is essential to our own health and that of the environment. But since the industrial revolution, the quality of the air we breathe has deteriorated considerably - mainly as a result of human activities. The pollutant emissions from road vehicles are regulated separately for light-duty vehicles (cars and light vans) and for heavy-duty vehicles (trucks and buses). It is located in the atmosphere, air pollution is able to travel easily. As a result, air pollution is a global problem and has been the subject of global cooperation and conflict. Some areas now suffer more than others from air pollution. Cities with large numbers of automobiles or those that use great quantities of
The Government sets the minimum wage periodically. The Lithuanian national minimum wage is 800 litas (3600 EEK) a month. Environmental law The environmental laws of the Republic of Lithuania preserve fundamental principles of modern environmental protection, preventive actions, source of harm, integration, the pollution taxes and sustainable development. There are several taxes on State Natural Resources and pollution. The Law on Pollution Tax establishes that tax objects include emissions, certain products specified by the law, and packages with contents specified by the law. General requirements for waste prevention record keeping, collection, storage, transportation, utilisation and disposal to prevent its negative effects on the environment and human health are established in The Law on Waste Management. This law provides that the waste holder has to manage waste himself or transfer it to a waste manager. Enterprises, which during the

In this presentation I'd like to give a brief overview of clay bricks. I'll speak about 15min to allow time for questions at the end. Firstly clay bricks are known for centuries as one of the most solid and reliable structural elements is set to play a role in reducing global warming. Apart form the many benefits obtained from using clay bricks in construction, such as their durability, insulation properties and aesthetic qualities, recent findings show that they also produce less carbon emissions than any other masonry material. History (slide 3) In more detail the earliest bricks were dried bricks, meaning they were formed from clay- bearing earth or mud and dried usually in the sun until they were strong enough for use. The oldest discovered bricks, originally made from shaped mud and dating before 10000 BC, were found in Mesopotamia related to the first known cities. Ceramic or fired bricks were first introduced by the Romans. These were mainly flat, broad
Many different things cause the greenhouse effect. The amount of carbon dioxide in the atmosphere is increasing because of the massive consumption of fossil fuels such as oil, coal, and natural gas. Another contributing factor is the the amount of forest logged. Every second of the day the area of a football field in trees is cleared by either being logged or burnt. The potential costs of cutting down on greenhouse gas emissions might sacrifice economic growth and our standard of living. By doing this we might need to change our habits and behavior. Furthermore we need to make investments in technology we need to adopt green building practices and buy clean cars. We all can do our part to help the planet by making small changing in our lifestyle. Simply turning off the lights every time you leave the room will dramatically decrease the amount of carbon dioxide produced. Using fluorescent light bulbs
Writting a summary I read the following sections of the booklet „Europe. A journal for young people“. The booklet is listed in 7 sections:“ Europe in everday life“; „The European Union- what does this mean exactly?“; „How does the European Union work?“; „What exactly does the EU do?“; „Europe moves on_ the enlargement of the European Union“; „Europe and the wider world“ and „The future of Europe“. ‘Europe is somewhere else.’ This provocative statement opens the first chapter of „Europe. A journal for young people“. It is, of course, not true. As EU citizens, Europe is our home. It affects our lives in many areas. For example: money (euro is a common currency); flying has become much cheaper and safer; the police forces in the EU work closely together and European environmental protection lays down common standards. The second sections provides information about what does the European Union exactly means and when did 28 countries come ...
biofuel. District heating can provide cheap energy to consumers by using low-cost energy sources, such as wood, waste and surplus heat. Many of these resources can be of local origin and promote local business and industry. The main advantages with district heating are high security of supply through utilisation of domestic renewable energy resources, if available, low primary energy demand due to high conversion efficiency, as well as small CO2 emissions thanks to low fossil fuel use and the high energy efficiency. Incineration of waste with heat recovery to district heating may be used at very low cost. District heating also gives opportunity for cogeneration of power and heat with very high efficiency. District heating enables profitable heat supply with outstanding environmental performance but there are in many places various barriers to a prosperous DH development.
unreasonable to even think about producing a hybrid car. Mostly because producing all these different parts starting from mining raw materials to producing a car to recycling it takes hugh quantities of energy: electricity, fuel, natural resources etc. · In the end hybrids have a shorter lifetime so they dont save as much as they spend energy. · On the other hand buying a hybrid seems reasonable if you live in a big city. You will make a difference by reducing emissions therefore smog levels will reduce and also the city will become less noisy. · You will use mostly your electric motor which will pay off in traffic jams, when you wont burn fuel by waiting in a jam. It is up to the consumer to decide which meets their needs and principals, also considering that hybrids are fairly new, they will become more eco-friendly in time. Thank yo u fo r lis te ning !

Rhodia Energy Services will manage the design and construction of the two facilities, as well as the operations and sales of the biogas produced, it said in a statement. Rhodia has partnered with the Siyuan ethanol factory in southern China to treat waste water. The facility started up in March and will produce 150,000 cubic metres of biogas a day by January next year and reduce carbon dioxide emissions by 100,000 tonnes a year. The second project is based at the Nuoc Trong cassava starch factory in Vietnam, which has recently started operations. It will produce 150,000 cubic metres of biogas a day and reduce emissions by 12,000 tonnes per year. Rhodia said are working on plans to develop biogas in Thailand and Malaysia and had begun three projects in China and Vietnam. Areas where biogas is used in
For comparison with the prices in the table, electricity production from a conventional coal-fired plant costs about 4¢/kWh. Though in some G8 nations the cost can be significantly higher at 7.88p (~15¢/kWh).Achieving further cost reductions as indicated in the table below requires further technology development, market deployment, an increase in production capacities to mass production levels,and of the establishment of an emissions trading scheme and/or carbon tax which would attribute a cost to each unit of carbon emitted; thus reflecting the true cost of energy production by fossil fuels which then could be used to lower the cost/kWh of these renewable energies.

1980.Each of the last three decades has been successively warmer at the Earth's surface than any preceding decade since 1850. More than 90% certain that most of global warming was being caused by increasing concentrations of greenhouse gases produced by human activities.In 2010 that finding was recognized by the national science academies of all major industrialized nations. Affirming these findings in 2013, the IPCC stated that the largest driver of global warming is carbon dioxide (CO2) emissions from fossil fuel combustion, cement production, and land use changes such as deforestation. Its 2013 report states:Human influence has been detected in warming of the atmosphere and the ocean, in changes in the global water cycle, in reductions in snow and ice, in global mean sea level rise, and in changes in some climate extremes.

In the 1970s, oil shortages pushed the development of alternative energy sources. In the 1990s, the push came from a renewed concern for the environment in response to scientific studies indicating potential changes to the global climate if the use of fossil fuels continues to increase. Wind energy is an economical power resource in many areas of the country. Wind is a clean fuel; wind farms produce no air or water pollution because no fuel is burned. Growing concern about emissions from fossil fuel generation, increased government support, and higher costs for fossil fuels (especially natural gas and coal) have helped wind power capacity in the United States grow substantially over the last 10 years. The most serious environmental drawbacks to wind machines may be their negative effect on wild bird populations and the visual impact on the landscape. To some, the glistening blades of windmills on the horizon are an eyesore; to others, they're a beautiful alternative

the world's birth rate comparison. Leisure activities: Leisure activities range from taking part in grueling sports to relaxing with family and friends. Many people also devote part of their leisure time to the public service. Life expectancy at birth: total average is 81 years but if you look at genders separately it's: male 78 years and female 84 years. Environmental problems: air pollution from vehicle emissions and open-air burning; acid rain; water pollution from increased use of agricultural fertilizers. Education: The education system in Switzerland is very diverse, because the constitution of Switzerland delegates the authority for the school system mainly to the cantons. The Swiss constitution sets the foundations, namely that primary school is obligatory for every child and is free in public schools. The minimum age for primary school is about six years in all cantons
111, RT I 2004, 43, 298) Kyoto protokolli eesmärgiks on seatud siht vähendada kasvuhoonegaaside heitkoguseid Lisa I riikide seas aastatel 2008-2012 5% võrreldes aastaga 1990 (nn baasaasta). Eesmärgi saavutamiseks on esitatud kolm paindlikku mehhanismi (ingl Flexible Mechanisms): ühisrakendus (ingl Joint Implementation - JI), puhta arengu mehhanism (ingl Clean Development Mechanism – CDM), heitkogustega kauplemine (ingl Emissions Trading - ET). Kaks esimest paindlikku mehhanismi on n-ö projektipõhised, mis tähendab, et KHG heitkoguste vähendamist käsitletakse üksikute projektide tasandil. Nad on suunatud heitkoguste vähendamisele majanduslikult kõige efektiivsemal teel. Kolmas Kyoto mehhanism- heitkogustega kauplemine- ei anna reaalset vähenemist, kuid võimaldab riikidel oma KHG heitkoguste vähendamise kohustust täita teistelt riikidelt ostetavate lubatud heitkoguse ühikutega.

weather events, such as droughts, floods, and hurricanes, are occurring concurrently around the world, giving rise to an unprecedented loss of human life and property. Increases in the frequency and intensity of heat waves and precipitation have also been observed. Consequently, a growing number of exotic animals are now on the verge of extinction. More disappointingly, the above- mentioned climatic changes, combined with heedless deforestation and noxious industrial emissions will not only affect animal life by changing important habitats but will also contribute to soil erosion and leaching. Thus, crop yields are expected to continue to drop in coming decades, resulting in widespread famine. Moreover, many regions will face dwindling water supplies as the result of shrinking glaciers and snowpack, evaporation, and the infiltration of salt water. Acute food and water shortages will presumably bring about manifold health problems.

The future of nuclear power As of 2007, Watts Bar 1, which came on-line in February 7, 1996, was the last U.S. commercial nuclear reactor to go on-line. This is often quoted as evidence of a successful worldwide campaign for nuclear power phase-out. However, even in the U.S. and throughout Europe, investment in research and in the nuclear fuel cycle has continued, and some nuclear industry experts[30] predict electricity shortages, fossil fuel price increases, global warming and heavy metal emissions from fossil fuel use, new technology such as passively safe plants, and national energy security will renew the demand for nuclear power plants. According to the World Nuclear Association, globally during the 1980s one new nuclear reactor started up every 17 days on average, and by the year 2015 this rate could increase to one every 5 days. Advantages and disadvantages on Nuclear power Advantages of nuclear power generation:
