what are natural resources?
Resources that exist naturally in the environment and may be exploited for social or economic objectives are known as natural resources. These resources are offered by nature; they are not the result of human activity. Resources that are renewable and non-renewable fall under these two broad groups.
Resources that may naturally regenerate themselves throughout time include fish, lumber, the sun, wind, and water. If handled responsibly, they may be utilized again without becoming exhausted.
Non-renewable resources, such as fossil fuels (coal, oil, and natural gas), minerals (gold, silver, and copper), and metals, cannot be regenerated after they are used up (iron, aluminum). Non-renewable resources are limited and, if not exploited sustainably, will ultimately run out.
Natural resources are essential to human communities and economies because they provide food for nutrition, energy for transportation and heating, and raw materials for manufacturing. The exploitation of natural resources, however, may also have detrimental effects on the environment and society, including pollution, deforestation, and the displacing of indigenous populations. To guarantee that natural resources are available for future generations, it is crucial to managing them sustainably.
