CAUSES OF GLOBAL WARMING
The main causes of global warming are human activities like burning of fossil fuels(coal, anoint and natural gas) and the clearing of land.
Burning of fossil fuels creates CO2,methane(which traps heat as much as 20 times than CO2) which slows the escape of heat into space. Trees and plants remove CO2 from air during photosynthesis.
Rapid Urbanization - Buildings, two commercial and Residential are responsible for G.W as they beseech a lot of fuel to be burnt which emits CO2.
20% of CO2 emitted in the atmosphere comes from burning of gasoline in the engines of vehicles.



study emitters of CO2 are U.S 22.2%, China 18.4%, European sexual union 14.7%, Russia 5.6%, India 4.9%.
Annual bill required to fight global warming is $50 billion as reported by Oxfam( A group of non-governmental organizations from 3 continents working worldwide to fight scantness and injustice).
Apart from burning of fossil fuels, Construction activity, other Major contributor of global warming in india is livestock of cows which is roughly 485 million(includes sheep, goats, cows, buffaloes ). They excrete methane after eating undernourished supplements. India emits 11.75 mensurable tons/year of Methane as on date.
