A study reveals deciduous trees with compound leaves more tolerant to air pollution.

Degrading air quality in metro cities is a matter of concern for public health. Massive tree plantation drives are often conducted in order to provide oxygen to choking cities. But trees, much like humans, also are severely affected by pollutants in the air. In such a situation, knowledge about trees capable of withstanding heavily polluted environment is needed, particularly while designing green belts in urban areas.

Neknampur lake serves as a fitting example of how low cost but effective natural techniques can be used to clean city lakes that are choking with pollutants.

A radical new method is fast emerging as an effective and sustainable solution to increasing pollution in urban lakes. Called floating treatment wetlands (FTW), they are artificial islands with plants that stay afloat on the lake. The plants clean the lake through hydroponics system, resulting in a cleaner, beautiful lake and an improved habitat for creatures that depend on it. We have already heard of this being successfully implemented in Hauz Khas lake in Delhi.
