1. Throw light on the vegetation of Ganga- Brahmaputra basin.
2. Ganga River is the most polluted river of the world. Enlist all the factors which
are responsible for the pollution of our Ganga River.
Answers
1)The basin shows varied trends in vegetation, which depend on the kind of landforms around the basin. We find tropical deciduous trees alongside the Ganga river and the Brahmaputra. Some common trees here are Sal, Teak and Peepal. The Brahmaputra’s plain particularly is home to Thick Bamboo groves while the delta region has plenty of mangrove forests.
As we descend down the basin and reach Sikkim and Arunachal Pradesh we find coniferous trees like Deodar, Pine and Fir. Since the temperature in these areas is comparatively cold here, coniferous trees are present in abundance here.
2)The main cause of water pollution in the Ganga river are the increase in the population density, various human activities such as bathing, washing clothes, the bathing of animals, and dumping of various harmful industrial waste into the rivers.
