Extreme hot summers nowdays - whose fault?

Extreme hot summers now a days - whose fault?

Definitely its our fault. The sun is shining the same as its used to many years ago. But we simply cut the trees, increased the pollution level,  grown concrete jungle, soaked water resources,

While we should plant as many trees as possible, reduce pollution, save water, save trees and slowly but surely we will help our Earth to be in balance again.
