If you have to choose a “Person of the Year” for 2005 , who will you pick ？For many of us ,the choice might not be a person at all . It would be Mother Nature（大自然母亲）.

While the world was still getting over the Indian tsunami（海啸）of December 2004 . Mother Nature went on showing her power throughout 2005 .

From July to October, about seven typhoons（台风）hit China’s coastal（沿海的）area.In August , the whole New Orleans city in the US was hit with its worst 一ever natural disaster , Hurricane Katrina . In early October , an earthquake in Pakistan killed more than 70,000 people .

Mother Nature was trying to give us a message:humans need to take responsibility（duty ) for the earth . She was just fighting back .

It is we humans who burn coal and oi1 to make electricity and power cars . This makes huge amount of greenhouse gases , which cause global warming .

It is we humans who cut forests and fill lakes to make space for buildings.This leaves fewer trees and lakes to keep floods（洪水）from rushing to towns and cities .

We need to work hard to ease（缓解）Mother Nature’s anger , or we’11 see more years of disasters.For example , we can start to use less electricity . Turn off lights , TVs and computers when we’re not using them . We can plant trees . One new tree a year from each of us can make a forest.

When you watch TV programs about wild animals, it is surprising to see how an antelope (羚羊) can run away from a strong lion. In the wilderness, everyone has his own way to protect himself. Even plants have their own ways to fight off enemies.

Over millions of years, plants have developed their own defense system (防卫系统). Chemicals are fantastically used by plants to survive (幸存). By making their leaves, flowers, roots and fruits poisonous (有毒的) to enemies, plants can fight back.

One such plant is the Golden Wattle tree. The British scientist David Cameron has found when an animal eats the tree’s leaves, the amount (数量) of poison increases in the other leaves. “It’s like the injured leaves telephoning the others to fight together against the enemy,” he said.

The tree also sends defense messages to neighboring plants by giving out a special smell. Golden Wattle trees in the nearby 45 meters will get the message and produce more poison within 10 minutes. Now, if an enemy eats too many of the trees’ leaves, he will die.

Every kind of plant or tree is good at producing a special set of chemicals. Herbivores, like rabbits, can safely eat the leaves of one tree, but they may be poisoned by its neighbor.

In this way, plants have not only developed their own defense system, but also shared it with others. This makes it impossible for a single animal to destroy even a small area of forest.
