Hundreds of thousands of visitors come from around the world to witness the spring majesty of Washington D.C.’s flowering cherry trees. This breathtaking event reminds us that trees are remarkable.
There are over 80,000 tree species and their progenitors have inhabited our planet for over 350 million years. They provide watersheds, supply drinking water for billions of people, protect cities from stormwater runoff, and reduce cooling costs to our homes and buildings by as much as 40 percent. City trees also absorb mega-tons of air pollutants each year.
Trees and ancient forests are superlative carbon dioxide warehouses. In return, ancient forests provide more than one of every three breaths of oxygen. Ancient forests provide invaluable habitat for animals. They are also vanguards of some of the most potent cancer, coronary and pain medicines known to science.
