Me and the world I live in

Our planet is our home. And it’s really an interesting world we live in! We fly to other planets and discover old manuscripts. We create artificial intellect and get to the depths of the ocean. We release tremendous energies and cause global disasters. We build the tunnel under the Channel (La Mansh), and in summer enjoy jasmin bushes all white with blossom. We must understand that science itself can’t be good or bad. Another thing is how people use its achievements. You shouldn’t forget about nuclear bombs, the Chernobyl disaster and ozone holes… And we pollute our beautiful planet. So there are a lot of problems facing people on the planet nowadays. The problems that demand world actions are: the growth of world population, economic crises, ethnic conflicts.

But the most urgent problem concerning the people of the whole world is an ecological one. What is ecology? Ecology is the science that studies the conditions of the habitat of man, animals and plants for the benefit of present and future generations.

“The planet Earth is our mutual home and the biosphere recognizes no divisions into blocs, alliances or systems. All share the same climate system and no one is in a position to build his own isolated and independent line of environmental defense”, said former Foreign Minister of Russia Eduard Shevarnadzer.

What is the environment? The environment is everything around us. It includes all living things. It also includes everything that is not alive, such as the soil, the air and the water. Human activities can make the environment unhealthy. The gasoline burned inside car engines produces gases that poison the air. Factories burn fuels to run machines, and these burning fuels, too, put poisons into the air. Human activities also poison water. Some factories produce liquid wastes that run into rivers. Often, these wastes contain poisons.

Sometimes, useful chemicals cause problems in the environment. When small animals eat poisoned insects, they take in the chemicals into their cells. When larger animals eat these small animals, the poison is passed on to the larger animals. The larger animals are eaten by still larger ones including people.

Many scientists study the environment. When there is a problem, they try to find out why. Then they look for ways to stop the problem. Scientists have also helped find ways to reduce air and water pollution. New cars burn fuel better and produce fewer poisons. There are laws against dumping poisons into the rivers and lakes. People who break these laws should be punished. Environment needs to be cleaned up. Unfortunately, millions of people of our planet live in areas in which the air is not safe to breathe. Air pollution can also cause a kind of water pollution called acid rain. The rivers and lakes become so acid that fish cannot survive, and neither can trees and other plants.

By knowing about these problems, we can do something. Humans can care for the environment so it will be a healthier place for all living things.
