On a recent trip to Los Angeles, we had the chance to visit one of the most green places in the city, TreePeople. TreePeople is a non-profit organization that focuses on educating city dwellers on the dire importance of tree planting in urban areas. Our favorite thing about TreePeople is their rainwater catpure programs. Rainwater is almost always overlooked as a source of water for municipal use. Cities and towns often have water shipped in from far away just to meet the population's needs, when in fact the amount of water that falls from the sky could offset water shipment by a huge percentage- creating a more sustainable system. If you're in the Los Angeles area, check out The TreePeople Campus which is part of the beautiful Coldwater Canyon Park- a 45 acre area in the hills above Los Angeles where you can hike, jog, picnic, birdwatch and smell some fresh, green air.
