There are heroes all around us. Mr Green is one. He has planted more than 400 trees in Los Angeles-He gives them to his neighbors. In fact, he has greened up (excuse the pun) his neighborhood. He first created a green nirvana in his front and backyard. His neighbors noticed and they wanted that greenery as well and now his whole block has a green touch. Interestingly, crime in their  area has gone down by 30%. Mr. Green is a true tree planting hero!
