Human Impact on Earth's Systems

Core concept

Overexploitation of resources — such as overfishing or excessive groundwater extraction — depletes resources faster than they can replenish, threatening long-term availability. Climate change, driven largely by human-caused greenhouse gas emissions, is altering weather patterns, melting polar ice, and raising sea levels globally. Addressing these impacts requires collective action, including sustainable resource use, pollution control, reforestation efforts, and international cooperation on climate policies.
