英语作文大佬看一下我写的作文考研09年英语一小作文 有没有语法错误，请点评一下 字难看了点抱歉了

你好，
only know... reduce it 也许可以改为：

building...system 也许可以改为：
building a system to collect plastic bags
What's more...plastic bag 也许可以改为
Furthermore (additionally), using cloth bags is a more sustainable way to substitute the use of plastic bags.
The problem...actions 也许可以改为：
The problem can be solved if we take effective actions.
And...better也许可以改为：
(Eventually/to sum up) The less white pollution, the better our environment.
不知道这样好不好，只是个人观点而已。谢谢🆗
