We must deal with it because it is bad for local wildlife and it makes our community look terrible.This mostly occurs in our local park. It is caused by people dropping food wrappers from the nearby fast food restaurant.So far, we make sure the park is cleaned every day. We have added more rubbish bins in the park to make it easier for people to dispose of this waste. We also spoke to the fast food restaurant and asked them to encourage people to dispose of their waste properly.There is a plan to add more bins and signs to inform people about the need to dispose of waste properly. We have also asked the restaurant to provide help in cleaning up their waste.The issue has been dealt with well, but more work is needed. It is hard to deal with these issues because there is a never-ending source of waste as people will always need to buy food. In the future, the best solution would be to find alternative ways of packaging.StepⅤ　Homework目前,环境保护已成为人们极为关心的问题。假设你受邀向国际中学环境保护论坛的征稿活动投稿,根据以下提示,用英语写一篇短文:1.简述目前的环境状况;2.环境污染产生的原因及对生活的影响;3.至少提出两个解决办法。注意:1.词数80左右;2.可以适当增加细节,以使行文连贯。Suggested answers:The world we live in is becoming more and more intolerable because of environmental destruction.

First of all, the environmental protection should be strictly put into effect. What’s more, every citizen should realize the seriousness of the problem and make efforts together to protect the environment.I believe we can make our world a better place.
