Researchers at Columbia University have developed an artificial tree. Why would we want artificial trees? Well, these trees can absorb CO2 about 1,000 times faster than natural trees, and will store it in its “leaves” until it is processed. Of course this prompts the question, “what’s the correct level of CO2 for the atmosphere?” But that may be a good problem to have.
I’ve never heard of that one. It would be interesting to do some more research on “artificial trees.” I’m wondering how large they will be and the most important, how much shade will they provide?
