How does habitat loss impact humans?
Habitat loss affects not only biodiversity but also impacts humans directly by decreasing production of ecosystem goods and services such as pollination (Potts et al. 2010 Ricketts et al. 2008) soil and water management (Bruijnzeel 2004) and carbon storage (Fargione et al. 2008).

Q2. How have human activities affected the depletion of flora and fauna? Explain. Answer: Cutting down of forests for agricultural expansion large scale developmental projects grazing and fuel wood collection and for urbanization has led to the depletion of flora and fauna.
How human activities affect species diversity?
How do human activities affect species diversity? Over-exploitation pollution and habitat conversion are the main threats to species diversity. They cause a gradual loss of species on local regional and global levels. Additionally the introduction of species into new ecosystems destroys natural balance.
What is destroying the grasslands?
How succession of grassland will be affected by overgrazing?
the weak overgrazed pasture will be highly susceptible to interrill rill and gully erosion which can lead to: loss of valuable topsoil reduction in soil organic matter and reduction in nitrogen pool to feed your forage.
