Local factors contributing to biodiversity loss include land-use changes, pollution, resource exploitation, and introduction of exotic species. Balancing human needs with ecosystem health requires doing more with less and preserving species richness for a sustainable future.

Global warming, caused by increasing greenhouse gas emissions, threatens biodiversity. As temperatures rise, species struggle to adapt, leading to extinctions and ecosystem disruptions. Melting ice contributes to sea level rise, endangering low-lying habitats. Additionally, increased carbon dioxide levels affect plant growth and biodiversity, potentially exacerbating climate change through feedback loops. Urgent action is needed to address these challenges and protect our planet's diverse ecosystems.
