Unit 4
Natural resources
Conservation is the safeguarding and preservation of natural resources, so that they can continue to be used and enjoyed. In the past, most people believed that the world’s resources could never be used up. Today, we know that this is not true. An important part of conservation is the prevention of waste – waste of forests, soil, wild-life, minerals and human lives.
As important is the fight against pollution of our environment, in particular, the dirtying and poisoning of air and water. Conservation is also concerned with the reclaiming of land by irrigating deserts, draining swamps or pushing back the sea.

Farmers can protect their land by yearly rotation of crops – that is, growing different crops on the same land from year to year. In this way, different elements of the soil have time to replace lost elements. Farmers can help enrich the soil by adding fertilizers. They can prevent erosion by ploughing along the contours of a hill rather than up and down. In this way water does not run off and take the soil with it.

Trees and shrubs are also needed to preserve land because their roots bind the soil and retain water. When all the trees in a region are cut, the soil can easily become loose and blow away.
Forests provide timber, one of Man’s most valuable resourses, but they must be managed carefully. Only mature trees should be cut, leaving the young ones to grow bigger.

To protect wild-life, many countries have passed laws restricting hunting and fishing. Wild-life preserves, areas where animals are protected within their natural environment, are becoming more common in regions where animal life is threatened.
