Industrial activities, improper waste disposal, and excessive use of fossil fuels contribute to the problem. Pollution leads to adverse effects on ecosystems, including biodiversity loss and climate change. Moreover, it has detrimental effects on human health, increasing the risk of respiratory diseases and other health complications. Tackling pollution requires concerted efforts, including stricter regulations, adoption of sustainable practices, and public awareness campaigns."
