Green house effect is caused by heavy or even low emissions of CO2 .Thus , one may also think that domesticating a cow may be the right option but , in fact , it also releases ( as every living being respires ( plants respire at night ) )  CO2 .Only , a ) rice cultivation is the apt choice here since cultivating it will lessen amount of CO2 present in atmosphere

actually, the reason for domestication of cow is that the cow releases  methane gas (through its dung ) which is used in the biogas plant for production of energy. and you should that a cow releases about 100kg of methane gas a year. this is the main reason why domestication of cows is an inappropiate option to stop green house effect.

deforestation and automobiles we all know is not the correct option. as cutting of trees causes elavation in the level of CO2 and leads to reduction of the O2 levels in the atmosphere, AND automobiles by burning petrol and diesel causes the air pollution by increasing the level of CO2 in the atmosphere.

so, at last the best option for reducing green house effect is rice cultivation as it helps in absorption of CO2 gas and release of O2 gas in the atmosphere.
