The peaceful use of nuclear energy is produced by nuclear fission. During the last two years more than 430 nuclear power plants are on stream producing about 15% of the world’s electrical power requirements.
Most people welcome this technology as it represents a low cost alternative to burning fossil fuels. Others are a bit more apprehensive and question the safety of these power plants, remembering only too well the accidents which occurred in recent times at Chernobyl, and Three Mile Island.
Nuclear reactors contain many controls and moderating materials to avoid the reactor from overheating and running out of control. But certainly in any reactor whose cooling procedures failed the core would become would become a metallic blob capable of melting through anything. The effects of a nuclear meltdown are as follows. –

Many individuals and world organizations dedicate themselves both justifiably and correctly in protecting endangered species of wild life.
Conservationists strive continually to protect such creatures as Pandas, Elephants, Seals, Rhinos, and Whales It would seem that there is some kind of built in mechanism to protect our fellow mammals, but what about the most common occupants of the oceans and rivers; the fish?
The general public either is not aware or does not care that approximately 90% of all species of fish have simply vanished, and that all of the world’s oceans and rivers are undergoing great ecological changes; the reason?; over fishing!!
The Effects of Over Fishing.

Any low lying area or flat coastal plain is vulnerable to the effects of sea level rises. With climate change seemingly being upon us, for whatever reason, there are certain areas which are already suffering from land loss due to increased sea levels.
Certain small, low lying Pacific islands are already experiencing tidal encroachment onto their land, and one can conjecture as to what becomes of their nationality if their homeland has to be completely abandoned.
It is currently estimated that sea levels increased globally by about 6 inches during the 20th century, and with the anticipated increase in global temperatures resulting in glacier and ice cap melting, it is difficult to see how further rises in sea level can be avoided.

Forests, and the trees they contain are essential for the well being of planet Earth. They play a huge role in determining the climate. They filter out unwanted carbon dioxide gas, and provide a shelter and habitat for millions of species.
Currently, primarily due to the action of man, these vital natural organs are being lost at an alarming rate, and it is estimated that 50% of forests have been lost in fairly recent times as a direct result of human activity, certainly during the last 175 years or so.

The Spanish translation of El Nino is literally “the Christ Child”, and was a term used by South American fishermen to refer to the warm currents of the Pacific Ocean at around Christmas time.
Today the term El Nino is still used to refer to the cyclic period of every 3-6 years when large scale warming of the surface of the Pacific Ocean occurs. This warming commonly last for about 9 months, but can stretch out to 18 months occasionally, and can have major impact on the worlds weather patterns.

Throughout the world today there is much evidence of the effects of climate change. There has undoubtedly been an increase in the intensity and number of hurricanes and tropical storms. Many countries have suffered from flooding, while other countries are experiencing drought and wild fires.
Further effects which have been predicted by science are now occurring as an effect of climate change. We are witnessing the shrinkage of glaciers, and the effects of global warming are causing loss of sea ice, with resulting rises in sea levels.
The effects of rising sea levels even today are posing a serious threat to some South Pacific islands, where people in the Marshal Islands are questioning their immediate future due to land loss.
