Other countries are restoring areas which have been reduced to waste land by mining. At Broken Hill in Australia drifting sand from rock crushing turned the area into a desert swept by sand storms. This is now being irrigated, fertilized and planted with grass and trees. In Great Britain quarries and gravel pits are being filled in or made into lakes, industrial wasteland is being turned into playing fields and waste tips into sloping green hills.

However Man tries to look after Earth , the fact is that he is using up at a great rate resources, especially fuel resources, which have taken millions of years to accumulate and which he cannot renew. Yet every day the Earth receives a huge supply of energy from the Sun. Man has made several experiments in using solar energy to heat furnaces, cookers, and water-distillers. In space technology, e.g. on satellites, solar cells convert sunlight into electricity. Houses and offices have been designed which are centrally heated by water or air heated by the sunlight. When Man can trap and store this energy, so that he can use it exactly as he needs it, he will have not only an endless supply, but a clean and safe one.

Treat with Respect

The speed with which Man is changing the face of Earth has outstripped（超过）all the mighty processes of nature put together. In his haste to supply himself with increasing quantities of Earth’s treasures, he risks destroying one he greatly needs, his natural surroundings. Some countries set aside unspoiled areas of natural beauty. Canada has the largest system of national parks in the world, covering about 13 million hectares, preserving the different landscapes and the plant and animal life.

Other countries are restoring areas which have been reduced to waste land by mining. At Broken Hill in Australia drifting sand from rock crushing turned the area into a desert swept by sand storms. This is now being irrigated, fertilized and planted with grass and trees. In Great Britain quarries and gravel pits(深坑) are being filled in or made into lakes, industrial wasteland is being turned into playing fields and waste tips into sloping green hills.
