I don’t usually write about the environment, but an idea that professor Klaus Lackner of Columbia University advocating building billions of artificial trees to capture the build up of carbon in the atmosphere is difficult to ignore.
Biopact (a pact between Africa and Europe to develop green energy) writes that “carbon capture, in the form of “artificial trees”, is one idea explored in the BBC Two documentary Five Ways To Save The World. But could these extraordinary biomimetic machines help to mitigate our excessive burning of fossil fuels and its potentially catastrophic consequence, global warming? Or would we be better off using real trees in a carbon negative energy system? Let us compare the two ideas.
In 2006, more than 29 billion tonnes of carbon dioxide were pumped into the atmosphere. And 80% of the world’s energy supply still relies on fossil fuels. German geo-physicist professor Klaus Lackner of Columbia University’s Department of Earth and Environmental Engineering, thinks he may have found a way of tackling our current excessive use of fossil fuels.
