The idea of sustainable development has been accepted by the world. How to keep sustainable development is a big problem facing our planet. The present situation is worrying. First, natural resources are becoming more and more scarce. Second, as some people are not aware of the importance of the environment protection, the problem with it remain extremely serious to some degree. The gap between the rich and the poor has the tendency to become wider and wider. To our great joy, many effective measures have been taken. On one hand, many countries have made relevant laws and regulations and put large amounts of money to the environ -mental protection. On the other hand, popularized education as well as international cooperation is being carried out. As to myself, I should take the responsibility to devote myself to sustainable development, because we have only one home. I will do what I can to balance economic develop -ment and a healthy environment.
