Ethical issues

- Greenhouse effect:
The earth is heated by the sun's energy. When this energy reaches the atmosphere, some is reflected back into space, another small part is absorbed, and the rest reaches the earth and warms its surface. But when the earth turn reflects energy into the atmosphere, something different happens. Instead of through it and reach space, the atmospheric gases absorb much of this energy. This helps keep the planet warm.
- Global warming:
Weather changes from day to day, and a few degrees more degrees or less from one day to the next very few seem. However, when referring to the global average temperature a few degrees more or less make a big difference. Scientists believe that if greenhouse gases are doubled, the global average temperature will rise between 1.5 and 4.5 degrees Celsius
- Disaster toxic waste:
The waste has damaged the environment and affected the lives of people. Between 1980 and 1985, they occurred in the United States 7000
Accidents during the transport of toxic waste on trains or trucks. These accidents released thousands of tons of toxic products. Thousands of people were evacuated and 139 died. One of these things also happened in Missouri and this oil fell on the roads of Times Beach.

THE GREENHOUSE EFFECT
The earth is heated by the sun's energy. When this energy reaches the atmosphere, some is reflected back into space, another small part is absorbed, and the rest reaches the earth and warms its surface. But when the earth turn reflects energy into the atmosphere, something different happens. Instead of through it and reach space, the atmospheric gases absorb much of this energy. This helps keep the planet warm.
Thus, the atmosphere let sunlight to pass through to warm the earth, but does not release radiation that Earth radiates into space. In a greenhouse the same, except that in the greenhouse glass is used, instead of gas, to retain heat occurs. So we call this greenhouse phenomenon.
Greenhouse gases of the atmosphere fulfill the function of maintaining the average temperature suitable for the Earth, although temperatures vary greatly from place to place. If these gases increase, they retain too much heat. This would cause global warming.

RISE OF THE SEA LEVEL
If Earth overheats, mountain glaciers and the ice of the North Pole and Antarctica begin to melt. Nobody knows exactly how much you could raise the level of the waters. But if measures are not taken to prevent the continued increase in global average temperature, the level could rise 20-40 cm by early next century, and continue to rise. Even a tiny increase in the level of sea waters could have catastrophic consequences. For example, much of the Netherlands has been reclaimed from the sea, and vast tracts of the country are below sea level. If this level rises, they could flood all such land or forcing expensive new build dikes. The Maldives, in the Indian Ocean, are also very low, and if the sea level rose a meter, almost completely disappear under the waves. If sea level rise of 4-8 meters, the consequences would be even more catastrophic.
