Answer:
Pollution, Quarrying, Illegal Logging
Explanation:
Pollution: People that throws away there trash in places that were never meant to be trash bins (lakes, oceans, roads, etc.)
Quarrying: Even though it can only be shown in environmental forums or in other websites, the fact that it is shown and not taken care of is bad.
Illegal Logging: Illegal Logging is bad especially if they don't plant 10 trees back. It is very simple to replant trees after taking them but not everyone does it.
