Catalyst: Plants and increased levels of carbon dioxide

We know that most plants use carbon dioxide to make their own food. So what might plants look like in 100 years if carbon dioxide levels continue to increase - will they become enormous and overtake our backyards? View the possible effects of changes in atmospheric carbon dioxide on plants and, in turn, humans and other animals.
