preventing pollution, and promoting natural regeneration, can help prevent this
from happening. Example- Over-exploitation, Pollution, Habitat destruction,
Climate change.
Actions to prevent renewable resources from becoming nonrenewable: Sustainable consumption, Reduce, reuse, recycle, Pollution prevention, Habitat conservation and restoration, Transition to renewable energy, Reforestation and afforestation, Water conservation, Sustainable agriculture, Community involvement.
