Stages and Phases
|General Statement||A disaster is something that does a lot of damage.|
|Definition||Sometimes, disasters hurt living things and the place where they live. These disasters are called environmental disasters.|
|Identification of classes||Water pollution can be an environmental disaster. Water is polluted when people put things such as rubbish into it. Air pollution can also be an environmental disaster. Air can be polluted by things such as gas or smoke.|
Sometimes oil is spilled into water. Most spills are accidents. The most common accidents are when an oil tanker hits another oil tanker, or when an oil tanker hits the rocks.
Toxic means poisonous. Companies use toxic gas to make chemicals. Large amounts of toxic gas can be very dangerous. It can hurt or kill animals and humans.
Nuclear power can be very useful, but it can also be very dangerous if something goes wrong. If there is an accident, it can cause dangerous radioactive fallout. This cannot be seen, but it quickly spreads over a large area.
Smog is a big cloud of polluted air. It is like very thick fog. It hangs just above the ground. In some big cities, a lot of coal and oil are used. These can make smog. In some cities there are lots of cars and trucks on the road. The fumes from the cars and trucks can make smog. The more pollution there is, the worse the smog gets.
