Answer :

Final answer:

The best estimate for species extinction each year is around 1,000, making option 'c' the correct choice. This number is significantly higher than historical extinction rates due to various anthropogenic factors. Understanding these rates is crucial for biodiversity conservation efforts.


Explanation:

Understanding Species Extinction Rates

The question pertains to the estimated number of species that go extinct every year. Current scientific research indicates that the rate of extinction is significantly higher than historical norms due to various factors including habitat loss, climate change, and human activities.

In recent findings, it has been suggested that around 1,000 species may go extinct each year, which aligns with option 'c'. Historically, background extinction rates were much lower, averaging between 1 and 10 species per year. The current crisis has escalated this rate considerably.

Reasons for High Extinction Rates

  • Habitat Destruction: Urbanization and deforestation lead to loss of ecosystems.
  • Climate Change: Alters habitats, making them unsuitable for some species.
  • Invasive Species: Non-native species compete with local wildlife for resources.
