Natural resources are materials or substances that occur naturally in the environment and can be used for economic gain. They include resources like water, minerals, and forests, which are essential for human survival and development. Proper management of these resources is crucial to ensure sustainability and prevent depletion. Renewable resources, such as solar energy and wind energy, are naturally replenished and can be harnessed without the risk of exhaustion. In contrast, non-renewable resources, like fossil fuels, are finite and can lead to environmental degradation if over-extracted. Balancing the use of these resources is vital for a sustainable future.
