Question

there is a need to check the present rate of urbanisation
GIVE REASON

Answer 1

Urbanization these days is so rapid and fast that we have forgotten our foundation. We have forgotten our real faiths, beliefs and customs and practices. 
Apart from that, urbanization is also a key element in causing pollution. It also results in destruction of wildlife and forest cover. 
Another reason can be that it results in exhaustion of the natural resources.
