Water Pollution

(THE  TRUTH)

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

(HOLD YOUR BREATH)

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.
