Q & A

What is biodiversity?

Biodiversity refers to the variety of all living things and their interactions, including various animals, plants, fungi, and microorganisms.

Who first coined the term 'biodiversity'?

Walter G Rosen first coined the term 'biodiversity' in 1985.

Why is biodiversity important for sustaining life?

Biodiversity is crucial for life as it provides nourishment, housing, fuel, clothing, medicines, and other resources, and it also supports ecological balance.

What are the different types of biodiversity mentioned in the script?

The script mentions three types of biodiversity: genetic diversity, species diversity, and ecological diversity.

How is genetic diversity defined in the context of biodiversity?

Genetic diversity is the variety of species expressed at the genetic level by each individual within a species, meaning no two individuals of the same species are exactly the same.

Can you provide an example of species diversity from the script?

Australia's Great Barrier Reef is given as an example of species diversity, being home to over 9,000 known species.

What does ecological diversity represent?

Ecological diversity represents the variety observed among ecosystems in a particular region, such as the differences between deserts, forests, grasslands, and oceans.

What is the economic importance of biodiversity?

Biodiversity is a reservoir of resources for food, pharmaceuticals, and cosmetic products. It also provides monetary benefits through tourism and is a source of the planet's real wealth.

How does biodiversity contribute to ecological stability?

Each species plays a specific role in the ecosystem, capturing and storing energy, producing, and decomposing organic matter, which supports services essential for the survival of animals and humans.

What is the ethical importance of biodiversity?

Biodiversity preserves different cultures and spiritual heritage, and all species have the right to exist. Human beings have no right to destroy habitats and biodiversity.

Why is it necessary to conserve biodiversity?

Conserving biodiversity is necessary to maintain ecological balance, preserve cultural and spiritual heritage, and prevent precarious situations that could arise from the loss of biodiversity.
