Protect Our Earth

A severe drought, which has a serious impact on people's lives and economic development, has begun in Southwest China. It is estimated that water scarcities at the drought's peak affected more than 20 million people, 10 million farm animals and billions of dollars worth of crops. Yes, our planet gives us everything we need, but natural resources are not infinite.

Fossil fuel such as coal, oil and natural gas, which were formed beneath the earth millions of years ago, are unrenewable resources. Because we depend immensely upon them, to conserve supplies of fossil fuels, scientists are testing alternative energy sources that can never be exhausted and will cause no pollution. It's also up to governments to outlay money into research and make strategic decisions for the future. But, there are great many small changes we can convert in our lifestyle, at the office and at home that keep burning less fuel.

Minerals are one of the major kinds of unrenewable resources that are vital for the construction, manufacturing and energy industries. Some are found in such abundance that we need not worry about while others are in shorter supply. Since it is important that the natural environment is protected from damage that may be caused by mineral extraction. To the factory owner, the word conservation means the reusing, recycling, or waste materials to make new goods; To us, reduce, reuse and recycle are important. We'd better to reduce the amount of stuff we buy and reuse things we already have. The last but not the least, Recycling possible for many household items. We may not be able to solve the landfill and polluted problems, anyway, we can at least help keep them from getting worse.

Timber and water renew themselves naturally. Fresh water is an important renewable resource. But the global demand for water is increasing and the destruction of water-dependent ecosystems, such as deforestation, has accelerated. Maybe this nature disaster, for instance the severe drought in China and in many places all over the world, is just a beginning warning to us. As the governments are taking some effects like forestation,irrigations, and so on to measure these, everyone individual should realize water crisis and use water-saving techniques.

It's time to think more about our earth! People need to respect the earth and try to preserve it. If not, what kind of future will we have?
