RE: Aeroplane And The Rocket Engine

Winter is very clean nowadays in Beijing which was like a dream for the native Beijing people a decade ago as the industries and the sandstorm from the north-western desert degrade the air quality. Also the eyesight becomes very short during this dry season with no clear view of the sun and blue sky becomes white.

I was amazed by the sight of trees being planted in China's deserts! It seems like sandstorms wouldn't occur if the deserts were lush with trees! Do you think Bangladesh's environmental pollution problem can be solved?

What is Ecency?
