6. More population means more mouths to eat food
which requires more agricultural production. More
cultivable land has been made available by clearing
forests and by reclaiming wet lands and ponds.
Advanced agriculture requires utilization of more
water, more fertilizers and more pesticides. And it
demands more space to construct houses and
availability of more consumer goods. It also requires
more means of transport, more consumption of fossil
fuels, and more pollution of land, air and water thus
growth of population leads to pollution of land, water
and air
