The ability to process carbon dioxide and other "non-breathables" from the atmosphere and return usable oxygen is contained solely in living things that contain chlorophyll. The more chlorophyll present, the more efficient the process.

Since forests have far more surface area (because of their leaves) than grassland, they are far more effective at reducing the carbon dioxide content of the atmosphere. As the number of trees is reduced (whether by deforesting the rainforests of Brazil and Africa, or by razing the great sequoias of the Pacific Northwest or other lumbering projects - or by drowning them under huge irrigation and power projects, like the damming of the Yangtze), the ability of our planet to "clean itself up" after we abuse it with our petroleum-based chemical reactions is also reduced.

Eventually, the plants won't be able to "clean" the air we breathe. And then the overall temperature will increase (the greenhouse effect), seas will rise as icecaps melt, and more arable land area will disappear as the arid regions expand their borders. In short, life as we know it will get tougher and tougher - and we'll either adapt or become extinct.
