Question: The greatest threat to global biodiversity is:
Options:
A) natural disasters such as storms.
B) pollution.
C) overexploitation of natural resources.
D) human alteration of habitats.
Show Answer
Answer:
Correct Answer: D
Solution:
The greatest threat to global biodiversity is indeed D) human alteration of habitats. Here’s why:
A) Natural disasters such as storms: While natural disasters can have a significant impact on local ecosystems and biodiversity, they are not the greatest threat to global biodiversity. Natural disasters are typically localized events, and ecosystems have evolved to recover from such disturbances over time.
B) Pollution: Pollution can certainly harm biodiversity by contaminating habitats and harming the health of individual organisms. However, its impact, while significant, is not generally considered the greatest threat to global biodiversity.
C) Overexploitation of natural resources: Overexploitation, such as overfishing or overhunting, can lead to a decrease in the population of certain species. While this can affect biodiversity, it is generally not as impactful as habitat alteration.
D) Human alteration of habitats: This is generally considered the most serious threat to biodiversity. Habitat alteration, which includes deforestation, urbanization, and changes in land use, leads to the loss of living space for many species. This can result in the rapid loss of biodiversity as species lose their habitats and struggle to survive.
So, the correct answer is indeed D) human alteration of habitats. It’s important to note that all these factors can interact and potentially exacerbate the effects of each other on biodiversity. Therefore, comprehensive conservation strategies are needed to address these threats.
