The application you've described isn't depressing. Carbon dioxide is a normal element in our atmosphere. Burning biofuels isn't a problem because the world's ecosystem is used to processing the levels of carbon dioxide that exist in current circulation. The problems that come from carbon dioxide in the atmosphere happen when you alter the levels of carbon dioxide faster than the ecosystem can react. This happens when burning fossil fuels on a large scale because it leads to adding more carbon dioxide into standard circulation. As there isn't a proportional increase in plant life ready to absorb this increase the carbon dioxide can have negative impacts on our environment, such as ocean acidification.
