How to prevent warming

Though summer is yet to set in, residents of Dhaka have already started to feel the heat. Offices, shopping malls and affluent people have started using ACs. ACs and refrigerators produce a huge amount of HFC (hydrofluorocarbon) which destroys the protective ozone layer of the Earth. Also, ACs require a lot of electricity the generation of which by conventional methods will emit more CO2 in the atmosphere warming up the environment even more. Planting trees can counterbalance the effects of warming. But who is going to do it? I think the responsibility should be divided proportionally among the responsible parties. Those who use ACs should take the lead. 

Also other energy saving methods like renewable energy, using energy saving bulbs etc. should be introduced to combat the problem. Otherwise, the city will become unliveable for all.
