Question

Livestock adds to global warming. Explain

Answer 1

The livestock sector, Food and Agriculture Organization, generates more greenhouse gas emissions upto 18% of carbondioxide. Global warming is a result of the increase of the greenhouse effect that is probably due to human activity. So there will be large scale changes in local climate, rainfall levels and temperatures (increases and decreases). This will have major impact on human populations in already marginal agricultural areas.
Sea levels will also rise due to the melting of ice caps and the increase in the volume of the oceans because of thermal expansion.
