This document discusses different types of pollution including land, air, water, noise, and visual pollution. Land pollution results from dumping garbage and waste onto the earth's surface. Air pollution occurs when additional gases, particles, or odors are introduced into the atmosphere and disrupt its natural balance. Water pollution is the contamination of water bodies by human activities when pollutants are discharged without proper treatment. Pollution can negatively impact human health, quality of life, and ecosystems. Some ways to reduce pollution include choosing more sustainable transportation, saving energy, and reducing waste.
