Air pollution refers to harmful substances introduced into the atmosphere, affecting not only the environment but human health as well. This pollution is primarily caused by industrial activities, vehicular emissions, agricultural activities, and poor waste management. The repercussions of air pollution are severe, leading to respiratory conditions, cardiovascular diseases, and even cancer. Environmentally, it contributes to phenomena like acid rain and climate change, further driving the urgent call for sustainable practices worldwide.
