"IF PEOPLE suddenly disappeared from the Earth, the planet could recover and, within 1,000 years, it would look as it did 100,000 years ago. If insects disappeared, nothing on land would survive," said one of the authors of the report Rafael Gonzalez Urdaneta from Mexico.

The words show that it is stupid to think that human are the most important living thing in the world. We are just part of the ecosystem (生态系统) and other things may be much more important than us.

Over the course of millennia (千年), humanity has made an impact on ecosystems for better or worse. However, human activities in the past century has increased global concern about the balance between human life and ecosystems.

Each time we pick up a newspaper or turn on the radio, we read or hear that our very existence is under threat and, therefore, there is a need for action. The reasons are many and include global warming, deforestation, pollution, loss of biodiversity, famines and droughts.

However, the cause is common to all humanity. People are overexploiting natural resources, which taxes the Earth's capacity to its limits.

The UN report of Global Environment Outlook defines three driving forces affecting our global environment - political and economic problems made worse by rapid population growth.

Without the social, economic and political problems caused by humans, the global environment would probably be in much better shape.

In order to make the world a better place to live, we should know and protect the ecosystem around us.
