The energy sources most used today have a variety of bad effect on our environment. The coal mining destroys land. Transporting oil across the ocean has resulted in oil spills and destroys ocean life. The burning of coal and petroleum causes air pollution. A lot of people get cough when the air is polluted. People cannot enjoy pure fresh air because their lungs are affected by tuberculosis. Nuclear fission creates dangerous radioactive wastes. Living creatures and various organisms are really in danger.
The most widely used source of energy is petroleum. The chemicals that petroleum contains are used to make fertilizers, drugs, synthetic, fibres, plastics, and many other products. Like coal, petroleum also creates environment problems. Removing large quantities of petroleum from under the ground may cause the land to sink. Transporting petroleum may result in oil spills. Burning petroleum causes air pollution. The bad smelling from the combustion will make people become unhealthy.
In place where great amounts of coal are incinerated, as in power plants, antipollution devices can be used. These are expensive and not completely effective. A betterway to use coal would be to convert it first to liquid or gas. Either these ways produces more heat than heat produced by burning the coal.
Water is an important forest product. Forest soils are giant sponges. They soak up rain so that it seeps slowly into the ground. Most towns and cities depend on these forest reservoirs. Forests steams flow steadily in dry weather. When trees are cut, the soil is exposed. Then rain runs off quickly, causing erosion and flood. Erosion and flood will spoil everything.
Reforestation and the fight against fires, insects, and diseases are important parts of forest management. With present technology, we are looking forward to find other sources of energy that can substitute the' used up coal and petroleum.
