Generally, it is thought that the government has the ability and obligation to tackle environmental problems, while individuals' contributions seem to be very small. However, I believe that if the general public could be mobilized to join the campaign of environmental protection, better results would be achieved.

　　There is no doubt that, to protect the environment, the government plays a leading role by making policies, allocating funds and enforcing laws. However, without the participation of the general public, these measures could be futile in some cases. For example, establishing a forest park or a nature reserve may conflict with the interests of local people and they may oppose such a policy. So the first step is perhaps for the government to raise people's awareness of protecting their own homeland and persuade them to stop cutting down trees or poaching wild animals.

　　It is also said that the power of a single person is minimal, which is true to some extent, but with millions of individuals involved to take action, the effect would be huge. For instance, if every person could save a glass of water, the total amount saved would be considerable in a middle-sized city. Another example is air pollution in the urban area, which can be effectively addressed by encouraging people to take public transport. If individuals could give up driving private cars, the air quality would be obviously improved.

　　In conclusion, the government should make people realize that, with the effort of every person combined, they can make a difference in creating a better environment. Only by doing this, can we tackle the existing environmental problems and achieve sustainable development.(273 words)
