Human Impacts on Grassland

Grassland -- Human Impacts on Grassland

Human had caused a lot of changes to the landscape of and the animals in grasslands since a long time ago. Large areas of grassland have been turned into farmlands for growing crops and for rearing cattle. Sometimes, fires are started by human and they spread quickly through grasses and damage the soils. Moreover, a large number of animals have been hunted for their valuable body parts. For example, elephants were shot for their tusks, lions were killed for their fur and bison were hunted for their meats.

Many animals were hunted to near extinction such as the bison and buffaloes. Fortunately, the hunting of these animals had been banned. Today, only about 1% of grasslands is officially protected but governments are now more aware of this issue. In some places, national parks are set up to preserve the grasslands and grasses are replanted in some other places where grasses have been cleared for farming. This increasing awareness is certainly necessary in protecting the grassland biome.
