I actually agree that large scale farming has a bad impact, but I'm more thinking of intensive mono crop agriculture that destroys the land.

And I don't believe in fossil fuel. It doesn't make any sense to me that oil comes from dinosaur remains. I think it's abiotic. But that's me being pedantic. I do agree with your point that using cars more than is absolutely necessary is a waste of resources and creates pollution. Maybe the worst aspect though is the effect on our lifestyle, making us less active.
