The primary concern related to overpopulation is the strain it puts on natural resources and ecosystems. Increased population leads to higher demand for food, water, and energy, which can result in unsustainable practices that degrade the environment. Urbanization and habitat loss often accompany population growth, causing biodiversity decline and increased pollution. Moreover, overpopulation exacerbates issues like climate change, as more people contribute to greenhouse gas emissions. Addressing overpopulation through education, access to family planning, and sustainable development is crucial for achieving a balance between human needs and environmental preservation.
