Final answer:
Environmental issues encompass resource depletion, pollution, and loss of biodiversity. These are exacerbated by human population growth and the unsustainable use of resources, leading to habitat destruction, and climate change effects.
Step-by-step explanation:
Environmental problems can indeed be categorized as resource depletion, pollution, loss of biodiversity, all contributing factors to ecological imbalance. Resource depletion occurs when essential materials such as fossil fuel reserves and freshwater supplies are consumed at a rate faster than they can be naturally replenished. Pollution results from contaminants being introduced into the natural environment, causing adverse effects to ecosystems and human health. Loss of biodiversity is a critical issue that arises due to habitat destruction, overharvesting of species, the introduction of invasive species, and the overarching impacts of climate change. A decline in biodiversity due to human population growth leads to a cascade of problems, such as the disruption of ecological services that humans rely on, including food provision, water purification, and disease control.
