What exactly is water pollution? Water pollution happens when toxins and pollutants get into water and dissolve. These toxins and pollutants stop water from doing what it needs to do. A pollutant can be good or bad depending on the environment. Mostly, water pollution is caused by humans.
Water pollution can happen intentionally or unintentionally. Water pollution can happen unintentionally by nature. For example: the wind blowing pollutants into water. Intentional water pollution is mostly caused by humans. Any substance can break down and dissolve in water. Chemicals are also harmful to water. In the 1800s to 1900s, the Industrial Age was born. More products were made than ever, using massive amounts of water.
Fortunately, people have done their part to reduce water pollution. Back in the 1400s, the Romans built an aqueduct system. This system was built above ground with wells to transport safe water across the city. In the 1980s, North Americans and Europeans built special pipes to transport river water while exerting waste. Today, companies are making products that are biodegradable. That means they don’t dissolve in water as quickly. Products such as bags, cases, and luggage are biodegradable.
Water pollution is a global phenomenon. Nobody knows what will happen to the world’s water.
