Pollution is damaging the environment with industries contributing 52% of contamination, transportation 27%, and agriculture 10%. Various human activities like deforestation, littering, and waste from hospitals can pollute the air, land, and water and cause diseases like bronchitis, asthma, and emphysema. Small changes like recycling, reusing products, reducing waste, using renewable energy, and fining polluters can help prevent further environmental damage if everyone works together.
