Compare renewable and nonrenewable resources, and discuss the effects of each on biodiversity.
Andrei [34K]

Answer:

Renewable resources cannot disappear, non-renewables will not last forever. Non-renewable energy sources, such as coal, nuclear power, oil, and natural gas, are available in limited quantities.

Explanation:

A renewable resource, for example, is solar energy. It is renewable because the sun can never disappear.

Non-renewable resources take a long time to replenish, if this ever happens. Renewable resources naturally recharge over a relatively short period. Non-renewable resources are natural resources that exist in fixed quantities and can be utilized. Examples include fossil fuels such as oil, coal and natural gas.

Both types of resources have a big influence on biodiversity and people shouldn't be spending them without limit.
