Environmental pollution, carbon emissions, and global warming are tightly linked challenges that threaten ecosystems, human health, and global stability. Pollution from industries, vehicles, and agriculture releases harmful substances into air, water, and soil, while carbon emissions—mainly from burning fossil fuels and deforestation—are the largest contributor to greenhouse gases. These gases trap heat in the atmosphere, driving global warming, which has already raised average temperatures by about 1.3°C since pre-industrial times and is causing rising sea levels, melting ice, extreme weather, and biodiversity loss. Addressing these issues requires reducing emissions, transitioning to clean energy, and adopting sustainable practices worldwide
