How can humanavtivities affect the evolution of organisms?

Look around you at the products of artificial selection. From alpaca tom wheat man has ordered the evolution of these organisms to suit his needs.

Then there is habitat destruction where the migration of humans all over the earth has put a great selection pressure on organisms in adapting to human presence. Not all do and some are extinct from human migrations into their ranges and that is part of evolution to.

Then there is climate change which will put great selection pressure on all the organisms of the earth. Some populations will have the variations needed to adapt to a warming earth and these populations will have individuals selected and thus evolve into new forms in the coming years.
