【答案】Dear citizens，
Nowadays，nature is constantly harmed by people，which in turn affects the life of the mankind.Take picnicking for example，fires caused by it have caused great damage to the wildlife and the forest.The rubbish left after the picnic also has negative impacts on the environment.
In order to cope with these problems and protect the ecosystem，we appeal to everyone's participation in fighting against unfriendly behavior.When getting close to nature，choose areas where tourists are allowed to get in.When having a picnic，never make a fire in the wild，especially in a forest.When returning home，get rid of all the waste you have produced.
Let's work together and start now!Your action counts.
                                                 Yours，
