Have you heard of thermal pollution?
Thermal pollution is defined as a sudden increase or decrease in the temperature of water which will affect oceans, dams, lakes, rivers or ponds by human influence. Most marine organisms have specific temperature needs and are unable to survive sudden changes.
Production and Manufacturing Plants that produce different products or wastewater facilities are often the culprits of this massive exodus of thermal pollution. They draw water from nearby sources to keep machines cool and release the water back to the source with a higher temperature. Now you might think this is minor as you take hot baths but he heated water alters the oxygen levels in the water and affects the natural environment underwater like the vegetation and wildlife and any marine life.
Imagine being in a hot office with the aircon broken and you can’t get out, you would go absolutely crazy and it will ultimately affect your health.
