What are two disadvantages of fossil fuels?

1. Environmental impact: Burning fossil fuels releases greenhouse gases into the atmosphere, contributing to global climate change and air pollution. This can have detrimental effects on human health, plant and animal life, and the environment as a whole.

2. Finite resources: Fossil fuels are a finite resource, meaning they will eventually be depleted. As they become scarcer, prices will rise and the process of extracting the remaining fuel becomes more difficult and expensive. This can lead to economic instability and energy supply shortages in the future.
