.... waste sites. i) CERCLA actions against dissolved corporations are permissible ii) If one is the owner or operator, liability may attach even if some other party in the past placed hazardous wastes there. ( The seller of a foundry was found liable under CERCLA when it was sold for $25,000, but was appraised at $200,000, suggesting the decision to sell was for disposal of hazardous materials.) A vendor is not an owner if it did not own the property at the time of toxic discharge from the facility. iii) A parent company may be considered the owner, despite t .....

.... around the planet. Today about 1.3 billion cattle are trampling and stripping much of the vegetative cover from the earth's remaining grasslands. Each animal eats its way through 900 pounds of vegetation a month. Without plants to anchor the soil, absorb the water, and recycle the nutrients, the land has become increasingly vulnerable to wind and water erosion. More than 60 percent of the world's rangeland has been damaged by overgrazing during the past half century. Cattle ranching has also been linked to Global Warming. The grain-fed-cattle complex is n .....

.... than in the eastern United States. This chart shows that not all fish, shellfish, or their food insects can tolerate the same amount of acid: Generally, the young of most species are more sensitive than adults. Frogs may tolerate relatively high levels of acidity, but if they eat insects like the mayfly, they may be affected because part of their food supply may disappear. As lakes and streams become more acidic, the numbers and types of fish and other aquatic plants and animals that live in these waters decrease. Some types of plants and animals are able to tol .....

.... the tin you must heat it with carbon to remove the zinc, copper, bismuth, and iron from the tin. Tin had been used for many things but tins use is dropping rapidly although tin is still used a lot for plating. Plating such things as electical contacts. Tin is also used as a protective coating. This protective coating can be as small as 15/1,000,000 of an inch. This protective coating protects against rust on steel and other metals. A coating of tin also gives a great look to plain old steel. Tin cans for food prevents weak acids from damaging th .....

.... a teacher assigns the students to send in all assignments by e-mail? Eventually, they will have to learn the basics of e-mail which, in turn, reveals even more problems with being computer illiterate. For an essay, the teacher requires that they go to the library to do research. The computer illiterate happily walks into the library to do their research. Imagine their surprise when they find out that the main tool of research is one of those darn computers. The poor illiterates stare blankly at a computer screen while the monotone library aide goes thro .....

.... it maybe what Meadows would like us to think, does not happen. With every industry, every aspect is carefully debated and analyzed for the short and long term outcomes. Any industry that capitalizes on earth's resources figuratively signs a pact with the earth. This pact bonds this industry to the earth and requires that any harvesting of resources is not done so with haste and waste. There is a symbiotic relationship between the two. For the industry to exist there must be a constant supply of the resource. Without a constant supply the industry dies. N .....

.... more than just black material, they are full of life forms. Some of these include giant clams, giant worms, and all sorts of different organisms. Up until recently, smokers have only been observed by videotape and "deep-diving submersibles". Last summer a team from the University of Washington and the American Museum of Natural History accomplished the task of bringing four "" to the surface. The method that the team used for retrieval was quite interesting. The team followed a "loggers technique" for detaching the smoker from the Earth’s crust. They used a .....

.... growing plants. The most obvious being that it is easier to control the plant growing environment. Some others are restricted supply of suitable water, lack of suitable soil, high labor cost of traditional cultivation, high cost of sterilizing soil, and there is a greater reliability and predictability of plant production. In addition, It's easy! Depending on what is being grown, most of the time hydroponic plants require less attention than soil-grown crops. Because of this, it can relieve some people of the added responsibility that soil-grown plants re .....
