Global warming refers to the increase in the atmosphere temperature. The temperature increases due to the emission of greenhouse gases. Greenhouse gases are emerged from the burning of biomass and from the consumption of petrol, coal, etc, can absorb temperature.
This can be reduced by :
1. Reducing pollution and waste.
2. Using more solar, wind and tidal energy.
3. New technology and eco-friendly means of production.
4. Afforestation
