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.

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

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.

If we over-breathe we lose carbon dioxide. The tissues then become starved of oxygen and then our body's systems start to spasm -it's then that we run into all sorts of health problems.
