We Are Close, Men And Land
Irena Vangjeli People have been living on the Earth for a long time. When they were few and their instruments of production were primitive, they did harm neither themselves nor the planet. But now the population of the planet is growing persistently and economics is developing actively. Technological progress has come to its highest point. Huge multi-million cities with plants and factories replace forests and vales. Natural resources are actively used by people. A lot of cars, ships, planes have appeared. Man has even discovered the space. But these changes can't pass without leaving a trace. A lot of problems that make us think have appeared. One of such problem is the problem of air pollution. Annually millions of cars and factories release millions tons of harmful substances into the air. As a result, the ozone layer defending our Earth from dangerous sunrays is destroyed, and people get various diceases. Seas, rivers and lakes are polluted, too. Vast space os seas and oceans are at the edge of the ecological catastroph because of occasional with sheps bransporting oil, poisonois substances and other things. Evetything alive is dying, the resources at the oceans are destroyed. As a result of air and water pollution acid rains begin to fall. Trees and plants, whole forests perish because of them. Natural resources are nearly exhausted and cutting down trees edused soil erosion. There are a lot of ecological problems and they must be solved quickly. We can try to stop air pollution, to use ecologically pure hydrogen instead of petrol for cars, and also to forbid transportation of poisonous substances by sea. We can use the energy of Sun, wind. If we don't stop what kind of future expect our planet? |
