I still don't understand why our government would be responsible to contaminate the oceans.
This is only a poll. Somebody has even voted for the last option.Anyways, you should vote for the best option you think is the cause.
As far as the government is considered, I am not blaming anyone. The thing is who is letting people contaminate oceans and dump toxic chemicals into it? The poll is created just to have an idea of what people think about it. I am not in a favor to debate about each and every option of the poll, so now, stop thinking about the last option of the poll
