When we make life easier for ourselves, we make it harder for nature, animals and plants including ourselves.

Nature protection.

Scientists say that the earth is becoming warmer and there will be major changes in climate during the 21st century.
World temperature could increase 2 degrees centigrade by the year 2040. The increase could be 3 times as great in the Artic and Antarctic regions. This could cause the ice sheet to melt and raise the level of the oceans by 1 to 2 metres. Many coastal cities would be under water.
This is happening because there is too much carbone dioxide (CO2) in the air. When oil, gas and coal burn, they create CO2. We send it into the atmosphere and heat the Earth. Scientists call this a greenhouse effect. So we must conserve coal, oil and gas.
Chemical s from power stations, factories and car exhaust fumes pollute the Earth. Winds carry this polluted air to other countries and continents. In the air such pollutants as sulphur dioxide (SO2) and nitrogen oxide (NO) make acid rain. It comes down and kills forests, nature reserves, national parks, crops and animal species.
Many materials get corroded as a result of the acidification. Damage to buildings occur. A special problem is the damage to cultural objects, monuments, buildings.
