I think most of the environmental pressure will come from pollution, and a lack of space. With so many people around, there''s going to be a lot of vehicle use, and things such as littering. We're going to have to change and start cleaning up after ourselves and limit the use of gas.
The pressure in the past will be: raising temperature and flooding, more Co2 in the atmosphere.
We might for example evolve to better extract the oxygen from the atmosphere and be better resistant to heat.
Answer: I believe that the environmental pressures that exist now and that may be shaping the human species are the use of land, the extraction of resources, greenhouse emissions and water use. This are being used by use more and more as we start overpopulating the earth.
