Pollution!
Every thing is polluted now a days
The surroundings
And the people too and it is difficult to maintain sanitation such a way is very difficult tooo!
The pollution can be reduced by planting trees but its not possible in developing country like india where the government itself is going for deforestation in the name of development!
And one of the main reason for pollution in our country is vehicular pollution
So weekly once the lockdown of the people in home or atleast lock down of buses and bikes reduce the pollution alot????
