Trees and forests are often referred to as the ‘lungs of the planet’ for a very simple reason: they produce oxygen. It is estimated that 1 acre of trees can provide the oxygen requirements of 12 people for a year.
Absorb Harmful Gases
In addition to absorbing CO2, trees also absorb harmful pollutant gases such as sulphur dioxide, ozone, ammonia, carbon monoxide and nitrogen oxides.
Trees cool the surrounding air by providing shade and by a process called transpiration cooling. This is where trees release water droplets from their leaves that cool the surrounding area when they evaporate.
