Water pollution 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 i...
Agriculture About 77 per cent of the land area of Britain is under agricultural use of some sort. However, the sector's role in the economy is much smaller than in most other major industrial countries, in terms of employment and contribution to GDP, reflecting Britain's early industrialization. Agriculture employs less than 2 per cent of the population and contributes 2 per cent of GDP. However, it achieves high levels of efficiency and productivity. Britain is self-sufficient in 58 per cent of all types of food and animal feed. Large parts of Britain, notably in Scotland and Wales, are suitable only for grazing. Overall, in the first half of the 1990s about 39 per cent of agricultural land was under pasture, another 27 per cent under rough grazing, and the remainder under crops or lying fallow. Over half of all full-time farms are devoted to dairy or beef farming, or sheep. Cattle and sheep con...
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 ...

Conditions of the productive animals in farms. The inescapable fact is that the conditions in big farms, especially in factory farms, are unacceptably bad. Recent proof of that was the Põima farm case in Estonia were 260 cows are starving. Animals are wet because of their own excrements, some spots on their body are furless, their bones poke out from their skin and they can hardly stand up. What is more, they do not have food or litter, so they lie on cold cemented floor that is covered with dung. This problem is not actual only in Estonia.Also the reality of Finnish factory farming was recently revealed. Producers arguments as there are severe problems related to intensive farming abroad and animals in Finland are treated properly, were more than doubt filling. That is why there was conducted an inquiry to investigate the real conditions in Finnish farms. During the investigation 21 Finnish broiler farms, 6...
Eli Whitney Whitney was born in Westborough, Massachusetts, on December 8, 1765, the eldest child of Eli Whitney Sr., a prosperous farmer. At age fourteen he operated a profitable nail manufacturing operation in his father's workshop during the Revolutionary War.[2] Because his stepmother opposed his wish to attend college, Whitney worked as a farm laborer and schoolteacher to save money. He prepared for Yale at Leicester Academy (now Becker College) and under the tutelage of Rev.Elizur Goodrich of Durham, Connecticut he entered the Class of 1789. Whitney expected to study law but, finding himself short of funds, accepted an offer to go to South Carolina as a private tutor. Instead of reaching his destination, he was convinced to visit Georgia. Georgia was a magnet for New Englanders seeking their fortunes. He invented the cotton gin, which was the beginning of his success. After he f...
