Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Mitigating the effects of habitat loss on human health requires strategies that protect and restore natural habitats, reduce our consumption of resources, and promote sustainable agriculture and land use practices. Increasing our reliance on fossil fuels, on the other hand, would exacerbate habitat loss and its associated negative impacts on human health.

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Functional diversity can be used in conservation planning to identify and prioritize areas for conservation, develop strategies for managing and restoring ecosystems, and assess the vulnerability of ecosystems to environmental change.

Multiple choice

Which of the following is NOT a potential application of functional diversity in conservation management?

  1. Identifying keystone species

  2. Prioritizing restoration efforts

  3. Assessing the impact of invasive species

  4. Predicting the effects of climate change
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

While functional diversity can be used to identify keystone species, prioritize restoration efforts, and assess the impact of invasive species, it is not directly used to predict the effects of climate change.

Multiple choice
