We mainly plant trees in forests, home gardens, or any open spaces. And this is the only simple and pure method to reduce carbon dioxide (CO2) in the air. In other words, trees are nature’s best air filters, absorbing CO2 and releasing oxygen (O2) for us. We can benefit from this throughout our lives, and…
