While some introduced species benefit humans and native species, invasive species outcompete natives, causing ecological damage. Invasive species often lack natural predators and can introduce diseases, parasites, and pathogens. It is important to recognize and mitigate the impact of invasive species on ecosystems to preserve biodiversity and maintain healthy ecological functions.

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.
