Man and Nature must work hand in hand
Environmental pollution is one of the most serious problems facing humanity today and it calls for immediate actions as it causes global warming, destruction of the ozone layer, and other potentially disastrous processes. Air, water and soil – all harmed by pollution – are necessary to the survival of all living beings. Badly polluted air can cause illness and even death. Polluted water kills fish and other marine life. Pollution of soil reduces the amount of land available for growing food. Environmental pollution also brings ugliness to our naturally beautiful world. People pollute their surroundings in many different ways. They dirty the air with gases and smoke, poison the water with chemicals and other substances, and damage the soil with too many fertilisers and pesticides. People ruin natural beauty by scattering rubbish and litter on the land and in the water and operate machines and other vehicles that fill the air with disturbing noise. Nearly everyone causes pollution in some way. Pollution problem is as complicated as serious. It is complicated because much pollution is caused by things that benefit people. For example, exhaust from cars causes a large percentage of all air pollution. Factories discharge much of the material that pollutes air and water. Thus, to end to reduce pollution immediately, people would have to stop using many things that benefit them. Most people don’t want to do it, of course. There are also many threats to wild creatures: wars, hunting, agricultural reclamation, pesticides, acid rains, deforestation. Each plant and animal plays a part in the delicate balance of all living systems. Thus the extinction of large numbers of species threatens the survival of other living things, including human beings. A growing number of animal species have become extinct in he wild and live only in captivity. Some zoos and animal research centres breed such animals and release them into protected areas with the hope of returning of their offsprings to the wild. In some cases the offspring can be trained to survive in the wild.
