Study Notes
Natural Resources
- Forests provide various resources including tannins, gums, drugs, spices, insecticides, waxes, honey, horns, musk, ivory, and hides.
Water Resource
- Water resources include rivers, lakes, oceans, and underground aquifers.
- Water is essential for agriculture, industry, household, recreational, and environmental activities.
Mineral Resource
- Mineral resources are non-renewable and include metals (e.g., iron, copper, and aluminium) and non-metals (e.g., salt, gypsum, clay, sand, phosphates).
- Some minerals consist of a single element, such as gold, silver, diamond (carbon), and sulphur.
Food Resources
- Resources used as food or providing food for organisms are called food resources.
- Agriculture is the primary source of plant food resources for humans.
Energy Resources
- Most energy used today comes from fossil fuels.
- Fossil fuels are non-renewable on a human time scale and can have harmful environmental effects.
Classification of Natural Resources
1. Inexhaustible Resources
- Resources that cannot be exhausted by human consumption, such as energy sources like solar radiation, wind power, water power, and tidal power.
2. Exhaustible Resources
- Resources available in limited quantities that will eventually be depleted with continuous use.
3. Renewable Resources
- Resources that are constantly available (like water) or can be replaced or recovered, such as vegetative lands.
- Examples include hydropower, solar, wind, and geothermal energy.
4. Non-Renewable Resources
- Resources that cannot be easily replaced once destroyed, such as fossil fuels and minerals.
Environmental Impacts
1. Overexploitation
- Harvesting resources at a rate that exceeds their reproduction or replenishment, leading to species extinction and ecological disruptions.
2. Mining
- Environmental impacts of mining include erosion, formation of sinkholes, loss of biodiversity, and contamination of soil, groundwater, and surface water.
3. Deforestation
- Results in loss of habitat for plants and animals, potentially leading to extinction, and disrupting ecological cycles.
