  mankind demand from earth, on the other hands; people are being accept the punishment of nature.

  Earth is a planet which around the sun and gives people a place to live. We have been living in earth for seven million years, and we constantly demand things from the earth. Nowadays, with people knowing on environmental issues, they have been discovered the environmental problem is the most important thing to develop. Overall, the environment problems are divided into two parts: energy consumption and waste of resources.

  First of all, with the development of the global economy, demand for energy is also growing because modern technology requires a lot of energy supply. For example, using too much petroleum energy can make acid rain and global warming. For another example, using wood products will cause a large number of tree felling, and then bring the earth soil erosion and mudslides, however; it is necessary because wood has become to Necessities of human life.

  The second of environmental problems is the efficiency of resource using. As we all know, the world's efficiency of resource using is very low for both developed and developing countries. The improvement of energy has become even more important with the development of science and technology because low energy efficiency will lead to the consumption of large quantities of energy, along with damage to the environment. For example, the gasoline efficiency of today's vehicles is only 50%, half of the gasoline emissions into the air. That makes environment more terrible. Moreover, because the world`s efficiency of resource using is very low and energy consumption, environment will face to lot of huge problems, such as global warming, acid rain, soil erosion, the hole in the ozone layer, and so on.

  In summary, if we reduce the waste of energy and improve energy efficiency, we can solve lot of environment problems. There are the two biggest causes of environmental problems, energy consumption and waste of resources.
