Question:
Write a brief note on Renewable resources ?
Answer:
Renewable Resources:
Renewable resources are resources which can be replaced or reproduced easily. Sunlight, air and wind
are resources that are continuously available and their quantity is not affected by human consumption.
Many renewable resources can be depleted by human use, but are replaced and the balance is
maintained. For example agricultural crops, take a short time for renewal; others, like water, take a
comparatively longer time, while still others, like forests, take even longer.
