Which of the following is true of overexploitation? Select ALL that apply.
a
Only animals are affected by overexploitation.
b
Overfishing is due to modern fishing techniques that can take a lot of fish at once.
c
Amphibians are overexploited for food, medicine, and research.
d
Overexploitation means harvesting species at a rate slower than the population can recover.
