Few measures for controlling carbon dioxide levels in the atmosphere are as follows
(i) Reduce the consumption of petrol in automobiles. Using car-pools and public transport helps in reducing petrol usage.
(ii) Use of alternative fuels such as CNG (clean fuel) instead of coal and petroleum.
(iii) Manure should be prepared out of litter instead of burning it.
(iv) The smoke coming out of the thermal power stations and other industries should be well treated to remove harmful gases, before discharging it into atmosphere.
(v) Planting more and more trees.
