Human kind is looking the barrel, if they continue to pollute the world like this, the isn't too far when the environment of our mother earth won't be possible for us live. I know man has made many changes which can't be revoked but i also know man is smart or intelligent enough to find new solutions to the problems and today i read about something very similar to that.
These are called the artificial trees. They do work the same way as the real ones. They cut down the CO2 level in the environment though they don't make food out of it. Also, it doesn't contribute to the level of O2 Oxygen in the environment. But, if it reduces the level of Carbon Dioxide......then it's worth it.
