Pollution And Water Quality
Seventy-five per cent of the ocean pollution comes directly from the land. It enters the ocean by drains, sewage, farm run-offs, and from industrial release into the waterways. It is important to understand that pollution and water quality affects microscopic life. The breeding cycles of shrimp and small fish may be disrupted. If the bottom of the food chain is effected the top will in time be effected. So here are seven issues to consider:
- To start with ocean pollution comes from domestic drainage and sewage. Most people are unaware that our drains are responsible for a significant amount of water pollution. If oils, fats, paints, household chemicals, like bleach and thinners used for cleaning, go down the drain, then it will end in the ocean.
- Storm water drains wash oils left on roads by cars, trucks and buses into drains. Roadside rubbish also ends in the ocean.
- Untreated sewage creates biological hazards for eco systems, and can create disease in marine life and humans. Sewage when treated limits water pollution but does not stop it from effecting water quality, the removal of sewage would be better not pumped into the ocean. The nutrients in the treated sewage effects water quality and may effect marine breeding on a microscopic level.
- Farm fertilizers ended up in river systems and enter our oceans. These fertilizers effect microscopic life, and many limit lava develop; of grill, shrimps and baitfish. Nitrogen found in many fertilizers is toxic to coral reefs like the Great Barrier Reef.
- Toxic forms of mercury come from coal - fired power plants and form mercury -based chlorine plants. Once mercury enters a waterway, natural bacteria absorb the mercury and convert it to methyl mercury. The Mercury enters by the food chain from small fish to large fish, mercury does not breakdown in fish but collects. Making large fish like Marlin, Tuna and Sharks toxic to eat.
- Industry is also responsible for releasing other form of contamination into the waterways. Such as chemicals, plastic or oil based pollution.
- Damming waterways effects water quality in rivers and estuaries. Simple put no freshwater no spawning of shrimp and microscope life and baitfish. Unfortunately stopping the food chains, and depriving fish of feed.
It's "food for thought" water pollution and poor water quality slows and damages eco systems, for abundant fish we need healthy breeding and feeding environment. All life is a fine balance and human pollutants and diverting fresh water hinders this process.
