がいいってトピックなんですけどこの文だと何割くらい取れるでしょうか(T_T) I agree that restaurants and supermarkets should try to reduce the amount of food that they throw away. Firstly,they can save money.In many cases,if they do not to try this attempt,the cost likely to get higher and higher.However,by joining,they will save theirs cost. Secondly,this attempt will become a public concern.For example,it can provide a good opportunity for them to consider the environment.Without to try attempt,they all could not have such an opportunity. In conclusion,I strongly agree with this opinion.
