Natural resources are materials or substances that occur in nature and can be used for economic gain or to support life. They are typically divided into two main categories: renewable and non-renewable resources.
Renewable resources are those that can be replenished naturally over time, such as sunlight, wind, water, and biomass. Non-renewable resources, on the other hand, are limited in supply and cannot be replaced on a human timescale; examples include fossil fuels (like coal, oil, and natural gas), minerals, and metals.
Natural resources are essential for human survival and development, providing raw materials for energy, food, water, shelter, and industrial goods. The management and conservation of natural resources are crucial for sustainability, ensuring that future generations can meet their needs without depleting or degrading the environment.
