And I will be speaking today about OVERFISHING. I will be speaking for about 10 minutes. I’ll be pleased to answer any questions you may have at the end of the presentation. INTRODUCTION: What is overfishing? What is causing overfishing? Why is overfishing a problem? Fishing down the food web. What can we do to help? WHAT IS OVERFISHING?: Overfishing can be defined in a number of ways. However, everything comes down to one simple point: Catching too much fish for the system to support leads to an overall degradation (degrödašon) to the system. Overfishing is a non-sustainable use of the oceans. WHAT IS CAUSING OVERFISHING?: Worldwide, fishing fleets are two to three times as large as needed to take present day catches of fish and other marine species (spiišis) and as what our oceans can sustainably support. On a global scale we have enough fishing capacity (cäpaseti) to cover at least four Earth like planets.
Fishery resources Capture fisheries resources are highly diverse. FAO landing statistics refer to about 2 500 species or group of species most of which are finfish. By far the most numerous fish species, and those most important to aquaculture and fisheries, are teleosts, or bony fish, which in the sea extend from small "grazing" species such as anchovy to large active predatory fish such as tuna. A similarly wide range is also found in freshwater, with the most important species from a production point of view belonging to the carp family. These account for over half the total of inland waters fisheries production. Marine capture fisheries resources are usually considered close to full exploitation worldwide with about half of them fully exploited, one quarter over exploited, depleted or
Industry and motor vehicle exhaust are the number one pollutants. Heavy metals, nitrates and plastic are toxins responsible for pollution. While water pollution is caused by oil spill, acid rain, urban runoff; air pollution is caused by various gases and toxins released by industries and factories and burning of fossil fuels; soil pollution is majorly caused by industrial waste that deprives soil from essential nutrients. FIND OUT 5 WAYS HOW TO STOP POLLUTION. 2. Global Warming: Climate changes like global warming is the result of human practices like emission of Greenhouse gases. Global warming leads to rising temperatures of the oceans and the earth surface causing melting of polar ice caps, rise in sea levels and also flash floods, excessive snow or desertification. FIND OUT 5 WAYS HOW TO STOP GLOBAL WARMING. 3. Overpopulation: The population of the planet is reaching unsustainable levels as it faces shortage of resources like water, fuel and food
productivity • The recent rapid increase in human population over the past three centuries has raised concerns that the planet may not be able to sustain present or future numbers of inhabitants. Loss of Fresh Water • Most of the freshwater resources are either unreachable or too polluted, leaving less than 1% of the world's freshwater, or about 0.003% of all water on Earth, readily accessible for direct human use. • According to the Global Outlook for Water Resources to the Year 2025, it is estimated that by 2025, more than half of the world population will be facing water-based vulnerability and human demand for water will account for 70% of all available freshwater. • Freshwater is the most fundamental finite resource with no substitutes for most uses, yet we are consuming fresh water at least 10 times faster than it is being replenished in regions of northern

This gear is generally used for target species tight on the bottom, such as angler, flatfish and Nephrops. By towing two nets side by side the effective swept area, and hence catch, is increased. As with the single demersal trawl above, otter boards (a) provide the horizontal spreading forces and floats and groundropes the vertical forces. The obvious difference in rigging is the third wire or central warp (b), which runs from the vessel to the clump (c), a heavy weight which can consist of short lengths of chain cable shackled together or a custom made device (Fig. 12) designed to roll rather than be dragged along the bottom

Environmental problems Nimi Klass Biodiversity The variety of life on Earth, its biological diversity, is commonly referred to as biodiversity. The number of species of plants, animals, and microorganisms, the enormous diversity of genes in these species, the different ecosystems on the planet, such as deserts, rainforests and coral reefs are all part of a biologically diverse Earth. Appropriate conservation and sustainable development strategies attempt to recognize this as being integral to any approach. In some way or form, almost all cultures have recognized the importance of nature and its biological diversity for their societies and have therefore understood the need to maintain it. Yet, power, greed and politics have affected the precarious balance.
Attention for water pollution exploded in the 1980s. The oil spill of the Exxon Valdez showed many around the world just how horrible the effects of water pollution could be. However, even the Exxon Valdez spill barely touched the surface of the problem of water pollution. The ship spilt only 5% of the oil spilt that year, and oil is just one of many pollutants that people dump into the water every year. Every year, 14 billions pounds of sewage, sludge, and garbage are dumped into the world's oceans. 19 trillion gallons of waste also enter the water annually. The problem of ocean pollution affects every nation around the world. This is especially true because water is able to transport pollution from one location to another. For many years, chemicals were dumped into bodies of water without concern. While many countries have now banned such behavior, it continues to go on today. As the world has industrialized and its population has grown, the problem of water pollution has intensified
These have no valid role at institutions of higher learning. The whole issue of scholastic competition needs careful review. Presently, space is so limited at many universities, and demand so high, that only students with the highest grades are accepted. Let us expand our ability to enroll students, and aim to admit all qualified applicants. This exclusion of non-A students bothers me more than high tuition rates do. Students in college can work summer jobs, such as fishing off Alaska, to earn their tuition; it is not necessary for parents or taxpayers to pay their way. Scholarships, based on deserving factors, are okay if endowed by private giving. I like to hope that even students of poor grades yet much promise might thereby get a chance to excel, as would very poor or otherwise handicapped ones. With the grades I received in high school, I did manage to get accepted by the University of Washington in 1980. But today there is no
Global Warming One of the biggest issues our planet and its inhabitants are facing nowadays is global warming. Global warming, also often referred to as the greenhouse effect, has not always been a problem. However, over the last centuries, since the Industrial Revolution things have changed. Polar regions are melting, species are dying, climate zones are shifting, migration patterns for animals such as polar bears and birds are being disrupted our world as we know it is changing. Some scientists believe that the climate will reach a tipping point, a point at which even a tiny additional increase would throw the system into violent change. We started doing harmful things and only now do we realize what we have done and what we are doing

The term Dioxin is commonly used to refer to a family of toxic chemicals that all share a similar chemical structure and a common mechanism of toxic action. Most dioxins and furans are not manmade or produced intentionally, but are created when other chemicals or products are made. This family includes: seven of the polychlorinated dibenzo dioxins (PCDDs),

degradation, climate change, animal cruelty and indigenous rights abuses in the countries where it is produced, as the land and forests must be cleared for the development of the oil palm plantations. According to the World Wildlife Fund, an area the equivalent size of 300 football fields of rainforest is cleared each hour to make way for palm oil production. This large-scale deforestation is pushing many species to extinction, and findings show that if nothing hanges, species like the orangutan could become extinct in the wild within the next 5-10 years, and Sumatran tigers less than 3 years. In total, 50 million tons of palm oil is produced annually, supplying over 30% of the world’s vegetable oil production. This single vegetable oil is found in approximately 40-50% of household products in countries such as United States, Canada, Australia and England. Palm oil can be present in a wide variety of products, including: baked goods, confectionery,
With each new discovery that shakes the fields of science, we would be there. Learning, educating and absorbing information daily takes up lots of time. With a life of eternity, we could learn endlessly. We could learn as many languages as we wanted and we could read every book that has ever been on our "to-do" lists. On the other side, one would have to factor in the mental part of immortality when one chooses physical immortality. The impact on human society would be another disadvantage. If most humans choose to be immortals, the Earth would obviously be not able to sustain them and their needs. We would be still threatened to non-natural deaths, like different illnesses, fire or flood. It would still take time to do things. If Iwere the only one living forever, I would have to watch people die around me, particularly myloved ones. I think this is the biggest disadvantages there is to living forever .

Protecting endangered species will make a difference in humans' life In the nature of humankind it is natural to hunt animals. However, nowadays hunting endangered species will make humans be just killers, because it is not necessary to kill something just to have a trophy on the wall at home. People can be proud of what they have done, but decreasing the population of a species largely will cause the specific animal breed to go extinct faster than it would happen via natural causes. Therefore, humans should stop hunting endangered species to slow down their extinction, as these species offer balance in the wildlife, are used without purpose in medicine, and may even reduce poverty. Species on the brink of extinction affect us more than we realize. Sure, pandas are cute, and rhinos are fun to look at, but is there anything more to that

m. A traditional English breakfast is a very big meal. It consists of juice, porridge, a rasher or two of bacon and eggs, toast, butter, jam or marmalade, tea or coffee. Marmalade is made from oranges and jam is made from other fruit. Many people like to begin with porridge with milk or cream and sugar, but no good Scotsman ever puts sugar on it, because Scotland is the home of porridge. For a change you can have sausages, tomatoes, mushrooms, cold ham or perhaps fish. But nowadays in spite of the fact that the English strictly keep to their meals many people just have cereal with milk and sugar or toast with jam or honey. The two substantial meals of the day are lunch and dinner. Lunch is usually taken at one o'clock. For many people lunch is a quick meal. Office workers usually go to a cafe at this time. They take fish, poultry or cold meat (beef, mutton, veal and ham), boiled or fried potatoes and all sorts of salad
"I am become death, the destroyer of worlds." So said the physicist Robert Oppenheimer, who helped to invent the atomic bomb. The two bombs dropped on Hiroshima and Nagasaki in 1945 killed around 200,000 Japanese people. No other species has ever wielded such power, and no species could. The technology behind the atomic bomb only exists because of a cooperative hive mind: hundreds of scientists and engineers working together. The same unique intelligence and cooperation also underlies more positive advances, such as modern medicine. But is that all that defines us? In recent years, many traits once believed to be uniquely human, from morality to culture, have been found in the animal kingdom (see part one in this two-part series). So, what exactly makes us special
started their Kingston Technology Company in Fountain Valley, California with hardly much financing 3 other than their savings. Nine years later they sold 80 percent of the company to the Softbank Corporation of Japan for $1.5 billion. The company is still going strong, and they still control 20%, after pocketing $1.5 billion. In 1997, former US President George W. Bush was asked to speak to a group of officials of Global Crossing Ltd., a telecommunications company, at a fee of $80,000. Since the company was supposedly short on cash, he was asked if he would prefer to take his fee instead in stocks of the company. In early February, 1999 the $80,000 stock had skyrocketed to over $14million. Who says some people are not intelligent than others. That was before Global Crossing decided to merge with U.S. West, Inc. and the stock went even higher. But wait! The man who started Global Crossing Ltd. In 1996,
and inventory management. Traditionally, marketing, distribution, planning, manufacturing, and the purchasing organizations along the supply chain operated independently. These organizations have their own objectives and these are often conflicting. Marketing's objective of high customer service and maximum sales dollars conflict with manufacturing and distribution goals. Many manufacturing operations are designed to maximize throughput and lower costs with little consideration for the impact on inventory levels and distribution capabilities. Purchasing contracts are often negotiated with very little information beyond historical buying patterns. The result of these factors is that there is not a single, integrated plan for the organization---there were as many plans as businesses. Clearly, there is a need for a mechanism through which these different functions can be integrated together. Supply chain management is a strategy through which such integration can be achieved.
To the north and south of this central mountain range on the main island lie vast stretches of mangrove swamps and coastal river deltas. /1/ Volcanoes and thermal pools are also found in the southeast of other islands. Papua New Guinea offers the greatest variety of terrestrial ecosystems in the South Pacific, including five types of lowland rainforest, 13 types of montane rainforest, five varieties of palm and swamp forest and three different mangrove forests. Two-thirds of the world's species of orchids come from New Guinea. /1/ Birds include 38 species of the bird of paradise, and the megapode and cassowary. Marsupials and mammals include cuscus, tree kangaroos, wallabies, bandicoots, spiny anteaters and, in the coastal waters, the dugong. There are between 170 and 200 species of frog and 450 species of butterfly. /3/ 4 The forests of New Guinea Richer and more diverse in species than their montane counterparts, the lowland

In 2006, about 18% of global final energy consumption came from renewables, with 13% coming from traditional biomass, such as wood-burning. Hydroelectricity was the next largest renewable source, providing 3% (15% of global electricity generation),followed by solar hot water/heating, which contributed 1.3%. Modern technologies, such as geothermal energy, wind power, solar power, and ocean energy together provided some 0.8% of final energy consumption.

Effects of Marine Oil Spills Oil spills can have a serious economic impact on coastal activities and on those who exploit the resources of the sea. In most cases such damage is temporary and is caused primarily by the physical properties of oil creating nuisance and hazardous conditions. The impact on marine life is compounded by toxicity and tainting effects resulting from the chemical composition of oil, as well as by the diversity and variability of biological systems and their
time to produce. The information is very useful and it is found to be very valuable, without the hardship and dedication from those scientists we would not have this knowledge. In this case we do find more value in knowledge that is obtained by hardship, but there have been situations where knowledge has been easily obtained and still found to be very useful. Edward Jenner observed people who had caught a disease called cowpox and noticed that they did not catch smallpox. His theory was that those who had been inoculated with cowpox would become immune to the smallpox virus. To support his theory he performed the world’s first vaccination on an eight-year-old boy by first inoculating the boy with cowpox virus and later with smallpox virus, without smallpox disease ever developing.2 There wasn’t much trial and error when it came to his experiment, he provided evidence for his theory and that’s how vaccinations came to be.

It is impossible to capture on film, to describe in words, or to explain to those who have never had the awe-inspiring experience of standing in the heart of a primary rainforest. Rainforests have evolved over millions of years to turn into the incredibly complex environments they are today. Rainforests represent a store of living and breathing renewable natural resources that for eons, by virtue of their richness in both animal and plant species, have contributed a wealth of resources for the survival and well-being of humankind. These resources have included basic food supplies, clothing, shelter, fuel, spices, industrial raw materials, and medicine for all those who have lived in the majesty of the forest. However, the inner dynamics of a tropical rainforest is an intricate and fragile system. Everything is so interdependent that upsetting one part can lead to unknown damage or even destruction of the whole

children and childhood has always been `more than preparation for adulthood`. 67 The Welsh Government believes that children are a`unique and valuable part of life, and the quality of those years is a matter that should concern us all`.68 The Welsh Government recognises children as right bearers where they acknowledge that children and young people are young citizens, `with rights and opinions to be taken into account now. They are not a species apart, to be alternately demonised and sentimentalised, nor trainee adults who do not yet have a full place in society`.69 Thereupon, the Welsh Government is determined to facilitate a cultural change that promotes a greater understanding and increasing awareness of children and young peoples` rights within society.

Although, in order to reduce it even further, urbanisation has to be reversed and a way to do this would be to provide people with work in the country side, as it is the main motivator. The second, pollution, is mainly the consequence of industry and transportation, namely vehicles. First one could be avoided by improving production techniques and technology, in addition to boosting the use of recycled materials. The same actions could be implemented to the transportation system for a great impact. The cities of this century are going to face many hurdles, amongst them overpopulation and pollution, in order to deal with them efficiently, multiple solutions are needed as only then we have a chance to succeed.

Territory). The Australian people are culturally the same as the Anglo Americans. There also live aborigines. Aborigines are the ancestors of the people. Like the US and Canada, Australia was an English speaking colony of Great Britain. Today Australia is a modern developed country with a diversified economy. Australia is an island continent of 7.7 million square kilometres, which makes it a little smaller than the USA. Located in south of Asia, between The Pacific and Indian Oceans, Australia is the World's driest continent. Although large areas of the centre are desert, Australia has a wide range of climate from tropical in the north to temperate in the south east, where it frequently snows in winter. Geographical position The coasts of Australia are surrounded by the Pacific Ocean, the Indian Ocean and the Southern Ocean.
