When trees grow, they act as vital "carbon sinks", taking in CO2 from the atmosphere and storing the carbon, releasing oxygen that we can breathe. This is incredible as CO2 is a major contributor to climate change, so every tree is offsetting CO2 as it grows, as well as creating healthy forest environment that supports native wildlife. In the race against irreversible and irreparable climate change, planting trees buys us more time to complete this difficult transition. But, beyond climate, reforestation also brings multiple benefits for ecosystems and people.
