Industries cause huge water pollution with their activities. These come mainly from:
Sulphur – This is a non-metallic substance that is harmful for marine life.
Asbestos – This pollutant has cancer-causing properties. When inhaled, it can cause illnesses such as asbestosis and many types of cancer.
Lead and Mecury – These are metallic elements and can cause environmental and health problems for humans and animals. It is even more poisonous. It is usually very hard to clean it up from the environment once it get into it because it in non-biodegradable.
Nitrates & Phosphates – These are found in fertilizers, are often washed from the soils to nearby water bodies. They can cause eutrophication, which can be very problematic to marine environments.
Oils – Oils forms a thick layer on the water surface because they do not dissolve in water. This can stop marine plants receiving enough light for photosynthesis. It is also harmful for fish and marine birds. A classic example is the BP oil spill in 2012 with killed thousands of animal species. Далее
There are many types of water pollution because water comes from many sources. Here are a few types of water pollution:
1. Nutrients Pollution
Some wastewater, fertilizers and sewage contain high levels of nutrients. If they end up in water bodies, they encourage algae and weed growth in the water. This will make the water undrinkable, and even clog filters. Too much algae will also use up all the oxygen in the water, and other water organisms in the water will die out of oxygen from starvation. Далее
Water pollution is the contamination of water bodies (e.g. lakes, rivers, oceans, aquifers and groundwater), very often by human activities.
Water pollution occurs when pollutants (particles, chemicals or substances that make water contaminated) are discharged directly or indirectly into water bodies without enough treatment to get rid of harmful compounds. Pollutants get into water mainly by human causes or factors. Далее
“Emmy” award-winning cinematographer, Shawn Heinrichs teamed up with model and diver Hannah Fraser to carry out a unique underwater conservation fashion shoot in a remote location in the South Pacific Ocean. The pair are aiming to raise awareness for the plight of the marine mammals at the hands of whalers. During the ten day shoot Fraser swam and glided with pilot and humpback whales.

“A consummate artist, award-winning photographer, David Doubilet began photographing underwater environments at the age of 12 in the cold, green seas off the northern New Jersey coast. He used a Brownie Hawkeye camera wrapped in a clear plastic bag, and he’s been behind the lens ever since. In 1971 he began contracting as a photographer for the National Geographic Society. He has captured groundbreaking images of great white sharks, flashlight fish, shark-repelling flounders, creatures of the undersea desert, flourescent coral, WW II wrecks and much more.
About his work for National Geographic, Doubilet says, “My job description is to make a picture of a place no one has ever seen before… or to make a picture that’s different of a place that everybody’s seen before”. Doubilet’s prestigious award winning photography include the “Sara Prize and International Award” given by the Mondo Sommerso Magazine in Italy. He was the first American and the youngest person to win this award. Далее
