What are natural resources?
Natural resources are resources that exist without any actions of humankind, including sunlight, atmosphere, water, land, and all vegetation and animal life.
How can natural resources be classified based on origin?
Natural resources can be classified as biotic (derived from living organisms) or abiotic (derived from non-living materials).
What are potential resources?
Potential resources are those that may be used in the future but are currently not utilized, such as petroleum in sedimentary rocks.
Define actual resources.
Actual resources are those that have been surveyed, quantified, and qualified, and are currently utilized.
What is a key concern regarding natural resource depletion?
Depletion of natural resources can lead to social inequity and loss of ecosystem services, especially in developing countries.
What is water pollution?
Water pollution occurs when harmful substances contaminate a body of water, degrading its quality and rendering it unsafe.
What are primary pollutants?
Primary pollutants are materials emitted directly into the air from sources such as vehicles and factories.
What is air pollution?
Air pollution is the presence of substances in the atmosphere that are harmful to health or cause environmental damage.
Name one effect of air pollution on human health.
Air pollution can cause respiratory infections, heart disease, and can worsen existing health conditions.
What causes land pollution?
Land pollution is caused by direct and indirect human activities such as dumping garbage, waste, farming, and industrial processes.
How can water pollution be prevented?
Preventing water pollution can include regulations on agricultural runoff, proper sewage treatment, and reducing industrial waste discharge.
What is the 'resource curse'?
The resource curse refers to the paradox where countries rich in natural resources experience less economic growth and worse development outcomes due to issues like corruption and inequality.
What is the role of soil in the ecosystem?
Soil provides essential nutrients, water, and an anchor for plant roots, making it vital for healthy plant growth and food production.
What are the two categories of air pollutants?
Air pollutants can be classified into primary pollutants (directly emitted) and secondary pollutants (formed by chemical reactions in the atmosphere).
Define biodegradable waste.
Biodegradable waste refers to organic waste that can be broken down naturally by microorganisms, minimizing its environmental impact.
How does deforestation contribute to pollution?
Deforestation affects air and water quality, reduces biodiversity, and increases greenhouse gas emissions contributing to climate change.
What are some methods to control pollution?
Methods to control pollution include reducing waste production, recycling, using cleaner energy sources, and implementing stricter regulatory measures.
What is the significance of reforestation in preventing land pollution?
Reforestation helps bind the soil, prevent erosion, enhances biodiversity, and improves land fertility.
