Natural resources are materials or substances found in nature that humans can use, encompassing both renewable and non-renewable elements. Examples include air, water, soil, minerals, plants, and animals. These resources are vital for human survival, development, and economic activities.

Natural resources are raw materials and energy sources found in the environment that are used by humans for various purposes. These resources come from the Earth and are essential for sustaining life and supporting human development. Natural resources can be classified into two broad categories: renewable and non-renewable.
1. Types of Natural Resources
A. Renewable Resources
These are resources that are naturally replenished over time and can be used sustainably if managed properly.
- Solar Energy:
- Description: Energy from the Sun that is harnessed through solar panels or other technologies.
- Uses: Electricity generation, heating, and solar-powered devices.
- Benefits: Abundant, sustainable, and doesn’t cause environmental harm when used.
- Wind Energy:
- Description: Power generated from the movement of air, typically harnessed by wind turbines.
- Uses: Electricity generation, mechanical energy.
- Benefits: Clean, renewable, and doesn’t produce greenhouse gases.
- Water (Hydropower):
- Description: Energy produced from the flow of water (rivers, waterfalls) using dams or turbines.
- Uses: Electricity generation, irrigation, and water supply.
- Benefits: Renewable, no emissions, and highly efficient when managed well.
- Biomass:
- Description: Organic material such as wood, agricultural residues, and waste that can be converted into energy.
- Uses: Heating, electricity generation, biofuels.
- Benefits: Can reduce waste, renewable, and provides a sustainable energy source.
- Geothermal Energy:
- Description: Heat from the Earth’s interior, typically accessed through hot springs or geothermal power plants.
- Uses: Heating, electricity generation.
- Benefits: Sustainable, minimal environmental impact.
- Forest Resources:
- Description: Trees, plants, and animals in forests that provide food, timber, medicinal plants, and biodiversity.
- Uses: Timber for construction, paper, fuel, and food.
- Benefits: Renewable if managed sustainably.
- Fisheries:
- Description: Marine and freshwater species that are harvested for food and other products.
- Uses: Food, economic goods.
- Benefits: Renewable if managed sustainably and fish stocks are replenished.
B. Non-Renewable Resources
These resources are finite and cannot be replenished on a human timescale. Once depleted, they are gone forever.
- Fossil Fuels (Coal, Oil, Natural Gas):
- Description: Energy sources formed from the remains of ancient plants and animals over millions of years.
- Uses: Electricity generation, transportation, heating, and industry.
- Drawbacks: Pollutes the environment, contributes to climate change, and is finite.
- Minerals:
- Description: Naturally occurring inorganic substances such as metals, gemstones, and other materials extracted from the Earth.
- Uses: Construction (e.g., sand, limestone), electronics (e.g., copper, gold), and industrial manufacturing (e.g., iron, aluminum).
- Examples: Copper, gold, silver, coal, iron ore, and rare earth elements.
- Nuclear Fuels:
- Description: Uranium and thorium are used in nuclear power plants to generate electricity.
- Uses: Electricity generation through nuclear fission.
- Drawbacks: Produces radioactive waste, limited in supply, and can pose safety risks
