Pollution and plants

bioindicators such as trees take note of many changes in the environment and will thus soon become valuable recorders of contamination, very convenient for environmental monitoring, reports D K Pandey et al of the Forest Research Institute, Dehra Dun, Uttar Pradesh. Tree bark remains in the environment for many years. …

Anti pollution figureheads

• Plants control air pollution by taking in carbon dioxide (CO 2 ) from the atmosphere and releasing oxygen. A peepal tree with a crown spread of 162 sq km releases 1,712 kg of oxygen and absorbs 2,252 kg of CO 2 per hour.• Trees not only mechanically stop smoke …

Cutting disgrace
