We all know the world has its problems, particularly where the environment is concerned. But not too many of us know the details, and the stories behind those problems.
The poisoning of the world's land, air, and water is the fastest-spreading disease of civilisation. It probably produces fewer headlines than wars, earthquakes and floods, but it is potentially one of history's greatest dangers to human life on earth. If present trends continue for the next several decades, our planet will become uninhabitable.Overpopulation, pollution and energy consumption have created such planet-wide problems as massive deforestation, ozone depletion, acid rains and the global warming that is believed to be coused by the greenhouse effect.The seas are in danger. They are filled with poison: industrial and nuclear waste, chemical fertilisers and pesticides. The Mediterranean is already nearly dead; the North Sea is following. The Aral Sea is on the brink of extinction. If nothing is done about it, one day nothing will be able to live in the seas.Every ten minutes one kind of enimal, plant or insect dies out for ever. If nothing is done about it, one million species that are alive today will have become extinct twenty years from now.Air pollution is a very serious problem. In Cairo just breathing the air is life threatening- equivalent to smoking two packs of cigarettes a day. The same holds true for Mexico City and 600 cities of the former Soviet Union.Industrial enterprises emit tons of harmful substunces. These emissions have disastrous consequences for our planet. They are the main reason for the greenhouse effect and acid rains. An even greater environmental threat are nuclear power stations. We all know how tragic the consequences of the Chernobyl disaster are.People are beginning to realise that environmental problems are not somebody else's. They join and support various international organosation and green parties. If governments wake up to what is happening- perhaps we'll be able to avoid the disaster that threatens the natural world and all of us with it.

This German physicist is considered one of the world's greatest thinkers in history. Not only did he shape the way people think of time, space, matter, energy, and gravity but he also was a supporter of Zionism and peaceful living.Einstein was born on March 14, 1879 in Ulm, Germany, and spent most of his youth living in Munich, where his family owned a small shop. He attended schooling in Munich, which he found unimaginative and dull. In addition to this, he taught himself Euclidean geometry at the age of 12.Later his family was forced to move to Milan, Italy where he then decided to withdraw from school at the age of 15. Eventually, he realized that he had to finish secondary school. On the other hand, he still often skipped class to study physics on his own.At age 22, he became a Swiss citizen and in 1903 married a woman, named Mileva Marec. In a few years, two sons were born but in 1919 he divorced as to marry his cousin.On the other hand, he published five major research papers at the age of 26.The first paper was on Brownian motion, which would get him his doctorate in 1905.The second paper laid the base of the photon, or quantum theory of light. It said that light is made off separate packets of energy, titled quanta or photons. The paper remade the theory of light. Also explaining the emissions of electrons from some solid objects when they are struck by light. Televisions are practical applications of Einstein's discoveries.The third paper, which he began as an essay at age 16, contained the « special theory of relativity ». He showed that time and motion are relative to the observer, and the speed of light is constant and natural laws are the same everywhere in the universe.The fourth was a mathematical addition to the special theory of relativity. This is where he presented his famous E = mc2, also known as the energy mass equivalence.His fifth paper was his general theory of relativity. In which he proposed that gravity is not a force, a previously accepted theory but it's a curved field in the space-time continuum created in the presence of mass.In 1921, Einstein won the Nobel Prize for physics for the confirmation of his general theory of relativity although the other papers where still considered controversial.In 1933, he moved to the USA where he became a citizen ir 1940. Einstein died in Princeton, NJ, on April 18,1955.
