These toxins are then eaten by plankton, which are eaten by fish, which are eaten by bigger fish, and that bigger fish could end up on our dinner plate. Also, toxic chemicals sitting beneath the seafloor could be spewed up and spread throughout the ocean. The homes of all types of marine critters could be gone in the blink of an eye.

As you can imagine, scooping up the ocean floor is easier for collecting clams, scallops, and oysters than having some scuba diver hand-pick them one by one.ĭespite its necessity, dredging can be pretty bad for marine environments. Also, it’s used for collecting precious seafood that live on the ocean floor via a chain mesh. Dredging is done for multiple reasons, including clearing a deep enough path for boats to travel through a necessity in this increasingly connected world. Essentially, this is what dredging does: removing sediment from the ocean floor. Depressing, I know, but this is essentially what is happening to marine life in oceans around the world-and in the picture above. Think of an underwater version of your favourite apocalypse movie. Imagine a giant net scooping up your entire neighbourhood, leaving behind nothing but a barren wasteland of what was once a thriving community. Do you like scallops? Did you know you could be contributing to this before and after picture if you answered yes?
