Answer:
It is difficult to say exactly what will happen to the amount of coal on Earth if humans continue to use it at the same rate, as it depends on a number of factors. However, it is generally accepted that there is a finite amount of coal on Earth, and that eventually it will run out if it is continuously mined and used at the current rate. It is also worth noting that burning coal has significant negative impacts on the environment, including air pollution and greenhouse gas emissions, which contribute to climate change. For these reasons, many countries are looking for alternative sources of energy and trying to reduce their reliance on coal.
