Healthy trees cool the planet by absorbing and storing harmful particulate pollutants and GHGs — in fact, a mature tree can absorb an average of 22lbs of CO2 per year. Planting trees can increase the resilience of ecosystems, help minimize climate change effects, and buy people and governments time to adapt to changing conditions. Planting native seedlings in ecologically appropriate areas can also counteract soil and biodiversity loss and improve human well-being.
