Is earth is a self sustainable planet?
Earth has many characteristics of a self-sustaining system, but it’s not entirely self-sustaining, especially in the face of human impact. Here’s how Earth achieves balance and where limitations arise: 1. Natural Cycles Earth operates through cycles like the water cycle, carbon cycle, and nitrogen cycle, which recycle essential elements and maintain equilibrium. These cycles support plant growth, replenish oxygen, and balance carbon dioxide, crucial for sustaining life. Limitation : Human activities disrupt these cycles, for example, by adding excess CO₂, causing climate change, or polluting waterways, which overloads Earth’s ability to restore balance. 2. Biodiversity and Ecosystems Diverse ecosystems create resilience, where different species interact to maintain the balance of resources. For instance, plants convert CO₂ into oxygen, which animals then breathe. Decomposers like fungi and bacteria break down waste, returning nutrients to the soil. Limitation : Habitat destruction, pol...
