6. The professor explains how to reduce the CO2 by giving two examples.
First, he describes creating talks about artificial trees. Artificial trees are made with plastics that are processed with chemical compounds. This trees can absorb CO2 thousands of times faster than natural trees. Also the CO2 storage in the artificial trees is permanent while natural trees release CO2 when they die or rot.

Second, he describes enhanced weathering. Scientists devised a way to speed up the weathering that absorbs CO2 in the process. (Need more explanation) First of all, rocks that react actively with CO2 are dug up and ground into fine powder. (Unclear meaning) Then the powder are spread over land. (Why's that?) When it rains, the CO2 is stored in this dust permanently through the weathering.
Those two ways illustrate how we can decrease the amount of CO2 in the atmosphere.
