ENVIRONMENTAL PROBLEMS

ENVIRONMENTAL PROBLEMS Our environment is constantly changing. However, as our environment changes, so does the need to become increasingly aware of the problems that surround it. With a massive influx of natural disasters people need to be aware of what types of environmental problems our planet is facing. Current environmental problems make us vulnerable to disasters and tragedies, now and in the future. Unless we address the various issues seriously we are surely doomed for disaster. Current environmental problems require urgent attention. 1

Essay on water pollution, global warming, acid rain, deforestation, intensive farming

Global warming Global warming, also known as the greenhouse effect, immediately received international attention. Scientists, environmentalists, and governments around the world took an interest in the subject. Global warming is called the greenhouse effect because the gases that are gathering above the earth make the planet comparable to a greenhouse. By trapping heat near the surface of the earth, the greenhouse effect is warming the planet and threatening the environment. Many scientists criticized Mr. Hansen's report, and the debate over global warming continues today. Current fears stem largely from the fact that global warming is occurring at such a rapid pace. Models are predicting that over the next century, the global temperature will rise by several degrees. Some scientists still do not think that the effects of global warming are as severe as some people say. They think that droughts, hurricanes, and floods often blamed on global warming might

PETROLEUM

fuels in consuming countries. Each crude oil has unique molecular characteristics which are understood by the use of crude oil assay analysis in petroleum laboratories. Barrels from an area in which the crude oil's molecular characteristics have been determined and the oil has been classified are used as pricing references throughout the world. Some of the common reference crudes are: West Texas Intermediate (WTI), a very high-quality, sweet, light oil delivered at Cushing, Oklahoma for North American oil Brent Blend, comprising 15 oils from fields in the Brent and Ninian systems in the East Shetland Basin of the North Sea. The oil is landed at Sullom Voe terminal in Shetland. Oil production from Europe, Africa and Middle Eastern oil flowing West tends to be priced off this oil, which forms a benchmark Dubai-Oman, used as benchmark for Middle East sour crude oil flowing to the Asia- Pacific region Tapis (from Malaysia, used as a reference for light Far East oil)

Dioxins and furans in the atmosphere

 Why are dioxins a problem? Dioxins are widely encountered toxic substances. They are found in all environmental compartments, are persistent and, being fat soluble, they tend to accumulate in higher animals including humans. Their resistance to degradation and semivolatility means that they may be transported over long distances and give rise to transnational exchanges of pollutants. In addition, dioxins which were released into the environment many years ago are still contributing to current exposure. Even very small dioxin concentrations can cause negative effects on the environment and on human health, in particular on the most vulnerable groups like children. Human health effects include impairment of the immune system, the nervous system, the hormonal system and the reproductive functions. Dioxins are also suspected of causing cancer.  How Are We Exposed to Dioxins?

Water pollution

oceans, and groundwater caused by human activities, which can be harmful to organisms and plants and for all of us. First, we have to talk about the causes of water pollution. Domestic households, industrial and agricultural practices produce wastewater that can cause pollution of many lakes and rivers. Industry is a huge source of water pollution, it produces pollutants that are extremely harmful to people and the environment. Dumping of litter in the sea can also cause huge problems. Different items take different lengths of time to degrade in water. Oceans are polluted by oil on a daily basis from oil spills, everyday shipping and dumping. Secondly, it is very significant to know about dangers of water pollution. Virtually all types of water pollution are harmful to the health of humans and animals. Water pollution may not damage our health immediately but can be

Keskkonnaprobleemid

Kui asi puudutab nafta ja vee segunemisesse, siis ookeanid kannatavad palju rohkema, kui lihtsalt mõningate lekete all. Kohutavad õnnetused jõuavad ajakirjandusee, aga sadu miljoneid liitreid naftat vaikselt satub merre iga aasta, põhiliselt mitte õnntuste tagajärjel. Nafta lekked põhjustavad haigusi ja tapavad Suured õnnetused ja lekked-isegi suhtliselt vähetähtis osa ookeani reostusest võib olla vägagi laastav. Sama suur kogus naftat võib teha mõnel alal rohkem kahjut kui teises kohas. Näiteks korallrahnud on nafta suhtes tunduvalt tundlikumad, kui liivarannad. Õlise ainega kaetud karvad või suled ei suuda isoleerida mereimetajat või sukelduvat lindu külmast veest ja kui loom puhastab end ta ka neelab naftat. Isegi, kui nafta kahjustus ei ole koheselt surmav võib see tekitada pikaajalist kahju. Kaladel võib see põhjustada maksahaigusi ja kasvuprobleeme. Kui nafta peaks sattuma mõningatele taimedele nt mangroovidele, siis võibsee seal säilida värskenaüle vi

Pollution of the Baltic Sea

Pollution of the Baltic Sea I have chosen to write my science report about pollution of the Baltic Sea. Nowadays it is a big problem to people who live in the marine region. In this report, I want to know the reason of this issue and how could we solve it. High population density, intensive agricultural production and other human activities have caused this high level pollution of the Baltic Sea. The shipment of crude oil has grown from 45 million tons to 175 million tons and this only by 10 years. Its condition is a challenge for the nine coastal states and their populations - there are 90 million people living in this catchment area. [1] The sources of marine pollution are municipal and industrial waste inputs directly into the sea or rivers, and atmospheric inputs mainly from traffic and farming. Originating from cellulose producing and from paper mills, large amounts of poisonous chlorinated compounds are polluting the coastal waters of Sweden and Finland
