    I found out a way to save the world from global warming. We need to create like a bacteria or organism that uses methane and carbon dioxide as a source of energy. We could do this by just adding certain genes that plants have, to bacteria or that organism, And than just sit and wait. Share this so that we could save the world. If you have and questions here is my email: [email protected]gmail.com.

    Myrtle avenue/broadway station in NYC needs massive amount of trees scattered around. There’s so much carbon dioxide under that train station that you best to believe there’s someone coughing up a lung every five minutes.

    trees need time to grow, and are hazards when hurricane or typhoon comes, while artificial air filters can last longer due being reinforced, and don't need water.

    Trees provide clean air. I should say "No doy!" but people have degenerated enough to actually require being told that trees are good.

  34. Indra Ida Bagus says:

    I think rather than basing on population density map, volume of traffic, speed, and the kind of vehicles would be the most effective way to see where to plant. Not only does commercial and office spaces not counted as population(maybe), planting on a street with 10 houses would be lest effective than a concentrated area where people work/shop.

  35. Amandip Singh says:

    cities in India surely need a lot more trees.
