Here is a common sense plan to reconnect trees to the city's watersheds, thereby saving much more rainwater.
This leads directly to saving much more money and rebuilding the economy, says Andy Lipkis, the founder and president of Tree People.
In this clear presentation, he explains how trees are a major part of nature's water system and that we can retrofit our towns to work with nature instead of against it.
He highlights the water issues in Los Angeles, where he enthusiastically believes this retrofitting can be a game changer and that it could save the city from collapse due to water inefficiency in the future.
