Does fishing and driving cause global warming?

Yes it does, overpopulation means more emissions into the atmosphere by the increased amounts of people and the clearing of forests to build more houses, agricultural land, industries etc. Fewer trees, less oxygen, more carbon dioxide, hence more global warming.

==================================

It is a good thing that the Earth is Intuitive and warms as more people are added..

We need the Warming to create more useful farmland to FEED the NEW Humans.
