Water pollution is the presence of substances and objects that contaminate water bodies. Caused by sewage, industrial waste, and radioactive leakage, water pollution affects human health and the whole ecosystem. Water pollution can be eased by not dumping trash into water and using environment-friendly cleaning technology.
Light pollution is the presence of excessive or misdirected artificial light. Light pollution disrupts ecosystem, harms many species including human, and wastes energy. Light pollution can be reduced by using right amount of light at the right place and time, using energy efficient bulbs, and shielding lights properly.
Pollution is very serious and need to be solved!
