Answer :
Final answer:
In the context of species extinction, the best estimate among the options is that around 20,000 species may go extinct each year. This reflects the broader understanding of the extinction crisis caused by human activities. The options also illustrate the disparity between small and large extinction estimates.
Explanation:
Understanding Species Extinction
Species extinction is a significant concern in biology and ecology, referring to the end of existence of a species. The numbers provided in the original question suggest choices related to how many species might be going extinct.
Analyzing the Options
The options are:
- A: 3 species
- B: 72 species
- C: 1000 species
- D: 20000 species
While 3 species going extinct per year may seem plausible, research indicates that much larger numbers are often cited in discussions of current extinction rates. For instance, some estimates suggest that between 1,000 and 20,000 species are at risk of extinction each year due to factors like habitat loss, climate change, and pollution.
Thus, between the provided choices, option D: 20000 species is typically seen as the most accurate reflection of current extinction crises.
