Read the text, then decide True or False:
The environment is everything around us, both natural and made by man. A major problem in the world today is the destruction of the natural envirinment. This is a complicated problem. We burn fuel, and this causes air pollution. We throw away plastc bags, containing toys and other subjects. These stay in the environment; they are not like paper or wood that slowly disappear. We have made thousands of new chemicals. Factories that make or use chemicals always have chemical wastes. These are often poisonous and thay also stay in the environment. Since 1945 several countries have been testing nuclear bombs in the air and underground. The explosions in the air cause nuclear fallout. The fallout causes cancer and kills animals and people. Nuclear power plants that make electricity also produce dangerous wastes and have accidents that can be very dissstrous.

There are many types of environment pollution in the world, air pollution is one of them. The main cause of air pollution is the smoke and dust released from factories. They are very toxic to us humans. And they are also very bad for the environment. In addition, air pollution is also generated from the exhaust fumes of motor vehicles such as motorcycles and cars. As a result, the air source in the flock is heavily polluted, causing a greenhouse effect, causing the Earth to heat up. The ice from the North and South poles is being melted due to rising sea levels, causing flooding. We need a way to fix them immediately, otherwise the consequences will be even more dangerous.
