Natural Resources
Natural resources are materials or substances that occur in nature and can be used for economic gain. They can be classified into two main categories: renewable and non-renewable resources.
Renewable Resources
- Renewable resources are those that can be replenished or replaced relatively quickly. Examples include sunlight, wind, water, and forests.
- Renewable resources are sustainable and have a lower environmental impact compared to non-renewable resources.
- It is important to manage renewable resources carefully to ensure their continued availability for future generations.
Non-Renewable Resources
- Non-renewable resources are finite and cannot be replenished within a human lifespan. Examples include fossil fuels (coal, oil, natural gas) and minerals (such as iron, copper, and gold).
- Non-renewable resources are often extracted through mining and drilling, which can have significant environmental impacts.
- Efforts to conserve and find alternative sources for non-renewable resources are important for sustainable development.
Impact of Human Activities
Human activities, such as deforestation, overfishing, and pollution, can deplete natural resources and disrupt ecosystems. Sustainable practices and conservation efforts are essential to mitigate these impacts.
