Have you ever wondered how pollution happens?

Water is often drawn from rivers, lakes, or the ocean for use as a
coolant in factories and power plants. The water is usually returned
to the source warmer than when it was taken. Even small
temperature changes in a body of water can drive away the fish and
other species that were originally present, and attract other species
in place of them. The warm water can deplete oxygen levels in water
and in doing so kill many animals that would otherwise lived on. This
is one of the many ways we pollute our water. Hazardous wastes are
chemical wastes that are either poisonous, capable of producing
explosive or toxic gases, capable of corroding steel, or flammable. If
not treated or stored correctly, hazardous wastes can pollute water
in our ocean. Fertilizers used to accelerate the growth of plants in
farms and gardens may be dumped into water. In the beginning,
these fertilizers encourage the growth of plants and in water.
Unfortunately, when the plants and algae die and rest underwater,
microscopic organisms decompose them. In the process of
decomposing, these microorganisms take up oxygen that is in the
water. Oxygen levels in the water may drop to dangerously low
levels that animals in the water, like fish, die. Oil spills arte a major
problem for all the animals in the oceans.

Air pollution is caused by factories which increase the amount of CO2
in the atmosphere as well as fueling smog. The same effect is caused
by cars and killing of plants (deforestation).
Fires also play an immense part in this problem and cause global
warming as well. These problems can be solved by using thing like
solar an hydroelectric energy sources as well as hybrid cars and
metal instead of lumber.
