Carbon dioxide is natural. It is not harmful. It is part of Earth's life cycle.

Limonene has been around forever, carbon dioxide as well. What we've been able to do is devise this catalyst for the first time that allows these two small molecules to come together to make a plastic.

Many ways of taking care of carbon dioxide are being studied, particularly carbon sequestration,

Carbon dioxide is the one thing that we've done nothing about so far, from really any of our economy aside by from increasing efficiency, and its the one thing that will substantially change the climate on time scales of 100 years or so.

In the course of the 1920s and 1930s, great progress was made in the study of the intermediary reactions by which sugar is anaerobically fermented to lactic acid or to ethanol and carbon dioxide.
