Why do scientists believe that fossil fuels will run out?

Answer 1

Because they are an exhaustible resource.

Fossil fuels are not renewable; unlike renewable energy sources like solar and wind power, fossil fuels can only be produced as long as they are physically present on Earth. Unlike water, which has an infinite supply, fossil fuels are used once, converted into energy and byproducts, and cannot be recovered to their initial state.

Scientists believe that fossil fuels will run out because they are non-renewable resources, meaning they cannot be replenished at the rate they are consumed. Additionally, the extraction and combustion of fossil fuels release carbon dioxide and other greenhouse gases, contributing to climate change. As reserves are depleted and environmental concerns mount, the need for alternative energy sources becomes increasingly urgent.
