Question:
Explain how increases in human population and per-capita consumption of natural resources can impact Earth's systems. Provide specific examples to support your argument.
✅ Answer:
Increases in human population lead to greater demand for resources such as water, land, and energy, which can result in overexploitation of these resources. For example, deforestation occurs when forests are cleared to make way for agricultural lands or urban development, impacting the carbon cycle and leading to increased greenhouse gases in the atmosphere. Additionally, higher per-capita consumption means more waste and pollution, such as plastic waste polluting oceans and harming marine life.
💡 Explanation:
- As human populations grow, the demand for natural resources like water, land, and energy increases, leading to potential overuse and depletion.
- For instance, deforestation for agriculture or development affects the carbon cycle, increasing atmospheric carbon dioxide levels and contributing to climate change.
- Increased per-capita consumption results in more waste, such as plastics, which can pollute ecosystems and harm wildlife.
- These examples illustrate how human activity can significantly alter Earth's systems.
