Topic Agree or disagree: People will stop subscribing to printed newspapers in the future. I agree with the idea that people will stop subscribing to printed newspapers in the future.

The kind of nature things has limit to use, so we should not use them too much. The plants also play role in the keeping air clean. This is the reason why I think it is bad for environment.
