Using the land wisely

Every year, there are more people on the earth using more of the earth’s resources. If people aren’t careful, the resources will be wasted, damaged, or used up.

To make space for the development of houses, roads, pavements, and car parks, people cut down trees and other plants. But careful builders leave areas in their developments where they plant trees to replace the ones they’ve cut down. This allows animals to keep their homes or find new ones.

Also, many governments protect some prairies, wetlands, forests, and other land from development.

Factories and other buildings can send waste chemicals into the air and water. So some countries have laws requiring builders to be careful so that new buildings don’t pollute the air and water.

Workers remove valuable resources from the land. If too much is taken, the supply will be used up. However, in many places, businesses save minerals by using better ways of mining and recycling mineral products. They also substitute more plentiful minerals for scarce ones.
