trees are to people作文？

Trees are very useful to people. They provide us with wood and other products. They give us shade and they help to prevent drought and floods

Unfortunately, in many parts of our country, people haven't realized the importance of trees. They cut them down at will. They are usually too lazy or too careless to plant and look after new trees. As a result, the forests continue to disappear.

Where there are no trees the rain falls on the surface, causing floods, and carries away with the rich topsoil, in which crops grow so well. When all the topsoil is gone, nothing remains but worthless deserted.

The big floods of 1998, in parts of China, have already taught us a good lesson. So every one of us must love trees, protect forests, and keep on planting trees each year.

How to protect rainforests？

如何保護雨林？

These days we often talk about the importance of our natural resources In many countries they are disappearing at a rapid rate and environmentalists are urging people everywhere to protect their air， water， forests， wildlife， and so on It is difficult to choose just one natural resource to save， but in my opinion， saving the forests should be the top priorityexamdacom

這些天我們經(jīng)常談?wù)撐覀冏匀毁Y源的重要性。在許多國家，它們正在以很快的速度消失，環(huán)保主義者敦促世界各地的人們保護它們的空氣、水、森林、野生動(dòng)物等等。很難只選擇一種自然資源來(lái)保存，但在我看來(lái)，保存森林應該是頭等大事priorityexamadacom

First of all， forests help to preserve other natural resources such as water， air， and animals Without forests， the land cannot hold water as well This means that in a heavy rain hillsides will collapse， causing great damage Not only that， but without the protection of trees， the nutrient－rich topsoil will be washed away and nothing will be able to grow on the land

首先，森林有助于保護其他自然資源，如水、空氣和動(dòng)物。沒(méi)有森林，土地也不能蓄水。這意味著(zhù)在大雨中山坡會(huì )坍塌，造成巨大的破壞。不僅如此，如果沒(méi)有樹(shù)木的保護，營(yíng)養豐富的表土就會(huì )被沖走，土地上什么也長(cháng)不出來(lái)。

Trees also help to clean the air by absorbing carbon dioxide and producing oxygen And， of course， forests are the natural habitat of many wild animals Without them， these animals will not be able to survive Another reason to preserve our forests is that large numbers of trees can help to mitigate the greenhouse effect by absorbing solar radiation

樹(shù)木還通過(guò)吸收二氧化碳和產(chǎn)生氧氣來(lái)凈化空氣。當然，森林是許多野生動(dòng)物的天然棲息地。沒(méi)有它們，這些動(dòng)物將無(wú)法生存。保護我們森林的另一個(gè)原因是大量的樹(shù)木可以通過(guò)吸收太陽(yáng)輻射來(lái)幫助減輕溫室效應。

And finally， forests are a place where people can get close to nature， and if they learn to love nature， they will want to preserve all the earth＇s natural resources

最后，森林是一個(gè)人們可以親近自然的地方，如果他們學(xué)會(huì )熱愛(ài)自然，他們將希望保護地球上所有的自然資源。

All of the earth＇s natural resources are important， and we should all work to save them The reason that I choose the forests as most important is because they help us in so many ways By saving the forests。

地球上所有的自然資源都很重要，我們都應該努力拯救它們。
