Identify the three main threats to biodiversity and explain how each damages diversity? Solution Answer) Three main threats to biodiversity are listed in details below; a) Deforestation and habitat loss - deforestation refers to permanently destructing the forests to make the land of forest be available for other uses. deforestation is performed by large scale burning of forests which makes a large part of unnecessary carbon emission to the environment. deforestation cause the loss in plant diversity (earlier available in those forests) as well as loss in fauna lived in those forests. b) Climate change - change in climatic conditions is a natural process which occurs at a very slow rate. but climate change due to human activities a rapid process which affect the environment in long terms. rapid climate change does not provide sufficient time for adaptation and a large part of biodiversity is lost. particularly, aquatic ecosystem is primarily affected by climate change. such climate change conditions are rising oceanic temperature, high carbon emission in environment, global warming etc. c) Overexploitation - To fulfil the requirements of rapid growing world population, often natural resources are exploited blindfold and over exploiting these resources result in loss of biodiversity such as over-harvesting lead that variety vulnerable to loss in its genetic diversity, overfishing makes that fish species vulnerable to extinction. there are other ways of overexploitation such as killing, hunting, poaching which result in losing diversity of fauna being exploited..

1. Identify the three main threats to biodiversity and explain how each damages diversity?
Solution
Answer) Three main threats to biodiversity are listed in details below;
a) Deforestation and habitat loss - deforestation refers to permanently destructing the forests to
make the land of forest be available for other uses. deforestation is performed by large scale
burning of forests which makes a large part of unnecessary carbon emission to the environment.
deforestation cause the loss in plant diversity (earlier available in those forests) as well as loss in
fauna lived in those forests.
b) Climate change - change in climatic conditions is a natural process which occurs at a very
slow rate. but climate change due to human activities a rapid process which affect the
environment in long terms. rapid climate change does not provide sufficient time for adaptation
and a large part of biodiversity is lost. particularly, aquatic ecosystem is primarily affected by
climate change. such climate change conditions are rising oceanic temperature, high carbon
emission in environment, global warming etc.
c) Overexploitation - To fulfil the requirements of rapid growing world population, often natural
resources are exploited blindfold and over exploiting these resources result in loss of biodiversity
such as over-harvesting lead that variety vulnerable to loss in its genetic diversity, overfishing
makes that fish species vulnerable to extinction. there are other ways of overexploitation such as
killing, hunting, poaching which result in losing diversity of fauna being exploited.
