Final answer:
Fossil fuels are non-renewable resources, meaning they do not replenish within a human lifetime and cannot be recycled after use. They are formed over millions of years from the remains of dead plants and animals and contribute to environmental issues.
Step-by-step explanation:
Fossil fuels are non-renewable and cannot be recycled. The term 'non-renewable' refers to resources that do not replenish within a human lifetime, which is the case for fossil fuels such as coal, oil and natural gas. These natural resources are formed over millions of years from the remains of dead plants and animals. As a result, once these resources are consumed, they cannot be replaced or reused. The usage of fossil fuels also contributes to environmental issues such as greenhouse gas emissions and climate change.
