1} answer -->
Biodiversity is the variability among living organisms from all sources, including terrestrial, marine, and other aquatic ecosystems and the ecological complexes of which they are part; this includes diversity within species, between species, and of ecosystems.
Biodiversity plays a crucial role in human nutrition through its influence on world food production, as it ensures the sustainable productivity of soils and provides the genetic resources for all crops, livestock, and marine species harvested for food.
2}answer--->
the depletion of flora and fauna in such a way as:
(a) Expansion of the commercial and scientific forestry and mining activities: Expansion of the industry causes a lot of trees to be cut and the soil is dug out during mining. This has caused depletion of resources.
(b) Agricultural Expansion: Today, even after independence, agricultural expansion is one of the major causes of depletion of forest resources. Between 1951 and 1980, over 26,200 sq. km.

1. What is biodiversity and why is biodiversity important for human life?
Biodiversity refers to the variety of life on Earth, including all plant and animal species and their ecosystems. It is important for human life in many ways, including:
- Food: Biodiversity provides us with a variety of crops, livestock, and seafood that we rely on for our diets.
- Medicine: Many medicines are derived from plants and animals found in biodiversity. For example, aspirin is derived from the bark of willow trees.
- Ecosystem services: Biodiversity provides us with many services, such as pollination, water filtration, and carbon sequestration, that are essential for the health and functioning of our ecosystems.
- Cultural and recreational value: Biodiversity also has cultural and recreational value, as many people enjoy spending time in nature and learning about different species.
2. How have human activities affected the depletion of flora and fauna? What are the negative factors that cause such depletion of flora and fauna?
Human activities have had a significant impact on the depletion of flora and fauna. Some of the negative factors that cause such depletion include:
- Habitat destruction: One of the biggest threats to biodiversity is habitat destruction, which occurs when humans clear forests, wetlands, and other ecosystems for agriculture, urbanization, and other purposes.
- Climate change: Climate change is also a major threat to biodiversity, as it can cause changes in temperature and precipitation patterns that can lead to the extinction of species.
- Pollution: Pollution from industrial and agricultural activities can also harm biodiversity, as it can contaminate soil and water and harm plants and animals.
- Overexploitation: Overexploitation of natural resources, such as overfishing and hunting, can also lead to the depletion of flora and fauna.
Overall, it is important for humans to take steps to protect biodiversity and minimize our impact on the environment. This can include things like reducing our use of fossil fuels, protecting natural habitats, and promoting sustainable agriculture and fishing practices.
