Why is Rudolp's nose red?

Hacking Nature

Hacking is a word that is often tied to something bad. However, there are times when hacking can be for something good. Think of it as a tool that can be put to use for good or bad. We also think of hacking as something only done with computers, but can we hack other things? Dr. Biology sits down with scientist Klaus Lackner to talk about how he is hacking the environment in order to pull carbon dioxide (CO2) out of the air. If he succeeds, it could help reduce CO2 in atmosphere and redirect it towards better uses.

Hacking Nature

carbon dioxide (CO2) molecule

Hacking the environment by mimicing what plants can do could help pull carbon dixode (CO2) molecules out of the atmosphere. Less CO2 would help the planet keep its cool.
