Trees are natural purifiers. Every tree you see around you absorbs harmful pollutants to return clean and breathable oxygen. In urban centers plagued with pollutants like carbon monoxide and ozone and respiratory irritants like dust and soot, trees act as a buffer mechanism to soak in all these toxins. The role of tress as nature’s detoxing agent cannot be overemphasized. With the world’s growing dependence on fossil fuels and widespread global deforestation, trees provide a time-tested mechanism to reduce the many harmful effects of air pollution and climate change.
