The environment is all around us and it’s an important part of our liver. It consists of:
The ATMOSPHERE – all the gases that make up the air including the weather systems, the greenhouse gases and the ozone layer
The LITOSPHERE – all the rocks in and on the Earth
The HYDROSPHERE – all the water in the seas, rivers, lakes and soils
The BIOSPHERE – all the living organisms on the Earth
However, humans do not always care for the environment as they should. People tend to prefer their own convenience and luxury over a healthy natural environment. People want more cars, bigger houses, the latest computer technology, packaged foods, etc. to make their life more comfortable. All of this growth pollutes nature and the environment. The number of people on the Earth is growing each year making our environmental problems worse. There is not an answer what’s the worst or the most serious, because all is connected and lots of things are caused by people themselves, because they treat our nature and environment very badly. The main problems are:
POLUTION: We can divide pollution into three categories:
Air Pollution
Soil pollution
Water pollution
Air Pollution:
Air is essential for life – not only for humans, but also for animals and plants. Although all living beings share the air, only people pollute. Traffic plays a large role in the creation of air pollution. The auto industry is booming. Cars, buses, trucks, motorcycles, and aeroplanes are an integral part of our contemporary way of life. They all produce exhaust, which often gets trapped in the cities due to the wind currents created by the cityscape, causing smog in heavy congested areas.
The other factors are factories and especially coal burning in power stations, which releases sulphur dioxide into the atmosphere. The wind spreads it in all directions and when this mixes with water in clouds – acid rain is formed. But not just only coal burning makes air pollution, lots of families cause pollution because of burning of fossil fuel for house heating and every family has 2 or more cars that also produce fumes.
That’s why we should use more public transport; go by bike or on foot.
Ground and Water Pollution:
Factories and power plants don’t pollute only the air alone, but also the ground and water. Many factories do not have an efficient cleaning system and they discharge their waste into the water system.
Acid rain makes trees grow more slowly, they grow old too quickly and then die. It kills fish in lakes because it’s very aggressive. It can also cause illness and diseases b
