Biodiversity Loss and


Conservation
Q1. What is the definition of an endangered species mentioned in
the video?

An endangered species is one that’s at serious risk of disappearing


forever. The video explains that this label is used when a species has a
rapidly shrinking population or is facing threats that could wipe it out
soon.

Q2. Define conservation as mentioned in the video.

Conservation, as described in the video, is the effort to protect and


manage the natural world—including animals, plants, and ecosystems—so
they don’t get destroyed or lost over time.

Q3. Why is conservation important for preserving biodiversity?

Conservation plays a key role in keeping nature balanced. Without it,


many species would vanish, which would disrupt ecosystems and harm
human life too—since we rely on biodiversity for food, clean water,
medicine, and more.

Q4. List some reasons mentioned in the video for why species
might become endangered.

The video outlines several reasons species become endangered, such as:

 Destruction of their natural homes

 Shifts in climate

 Overfishing and illegal hunting

 Invasive species that take over and outcompete native wildlife

Q5. How do habitat destruction, climate change, overfishing,


hunting, and invasive species contribute to endangerment?

Each of these actions harms wildlife in different ways. When humans clear
forests or build cities, animals lose the places they live. Climate change
alters environments too quickly for species to adapt. Overfishing reduces
fish populations, and hunting can push species close to extinction.
Invasive species often bring new diseases or compete for food, driving
native ones out.

Q6. What are the disadvantages of keeping endangered animals


in captivity, as mentioned in the video?

Captivity isn’t always ideal. The video explains that animals in zoos or
breeding centres can lose their natural behaviours and become less
prepared for life in the wild. Also, they might not have enough genetic
variety to stay healthy over generations.

Q7. How does inbreeding pose a risk to animals in captivity?

When a small number of animals breed over and over, it leads to


inbreeding, which raises the chance of genetic issues. These issues can
cause health problems, lower fertility, and make the animals less able to
survive and reproduce.
