The ecosystem is 1ike a chain.If any of the links are broken,the whole system is in danger.This  is  why  wetland  protection  has  been  put high on the agenda in recent  years.Zhao,vice--director of the State Forestry Administration,says nearly 60 percent of the country's natural wetlands are still not  under  effective protection.Most  Chinese  people  are ignorant  about  the importance of protecting the wetlands. Ocean,forestry and wetlands are the three global ecological systems.Wetlands can conserve and purify water resources, prevent flooding and help protect the ecosystem. As well as ecological values, they can also offer economical  returns. In recent years,many wetlands have become farmland.Drawing too much underground water,hunting and fishing also ruin their ecological system. Every year,the wetlands in the Sanjiang Plain of  Northeast China provide habitat for birds.Local residents search the area for the birds' eggs. They consider the eggs to be a natural gift. rather than wildlife that should be protected. If they were educated,perhaps this is one activity that could be brought to an end. China is now ready to make a plan to save some of these areas.Some have been restored to raise awareness among the public.But these moves are not enough.There should be laws in place to provide legal support to the fight. Environment protection is a campaign which needs support from everyone in society.Education may be the first step. Which of the following is WRONG?
We should protect wetland to offer habitats for birds. Some laws have been passed to protect wetland. Education and laws as well are both important for the wetland protection. Wetland protection won't be a success unless everyone offers their efforts.
