The CFC emitting from the before said devices and heavy & small industrial units, motor vehicles etc has a long life in the atmosphere. They multiplies the oxygen molecules and thus there forms huge holes in the ozone layer. Sun rays coming directly through holes creates harmful effects in the Earth and the Living beings.Atmosphere temperature may go high up to 7 degree C more than the normal heat.So this high temperature will harmfully effect the bio-diversity of the Earth.
Practicable solutions to control this fatal phenomena are a few things.
First of it is plant trees as much as possible.We have to plant trees about seven folds of the amount of present forests in the world.This trees are absorbing carbon in daytime for photosynthesis and emitting oxygen.Rooftop plantations can be effectively practiced to halt the heat emitting from concrete forests in the huge metropolitan cities of the world
