Which factor is suggested to better determine species extinction rates?

The most reliable factor for determining species extinction rates is rooted in the concept that economic considerations can greatly influence conservation efforts and, consequently, species survival. When economic factors are prioritized, negative impacts such as habitat destruction for development, pollution, and resource extraction often increase, leading to higher extinction rates. Additionally, funding for conservation initiatives, research, and habitat protection is largely determined by economic priorities. If the economy favors sectors that exploit natural resources without regard for biodiversity, species are more likely to face threats that could push them towards extinction. Thus, understanding the economic context surrounding species and ecosystems is crucial in accurately assessing extinction rates and implementing effective conservation strategies.

In comparison, population size, habitat complexity, and genetic diversity are indeed important for understanding species viability, but they are often influenced by economic factors. For instance, a species with a small population size may still thrive if its habitat is well-protected and there is adequate funding for conservation. Therefore, while all of these factors are significant, economic considerations serve as a critical underlying variable that can exacerbate or alleviate threats to species survival.
