Certainly possible. Problem is that the issues are very diverse. You have increased carbon, over-population, resource depletion, increased toxins in environment, etc, and each would require very different technological solutions. Also, I think solutions such as your bacteria idea would just make us lazy. We wouldn't fix the real issue but would just ultimately rely on technology to solve what are really social issues.
