Shocking footage showed a fish with trash and pollution inside of its body after a fisherman cut it open (video below).
In the clip, the fisherman can be seen pulling trash and plastic from the inside a dolphinfish -- items that included plastic lids, pieces of cups, a lighter, a comb and bottle tops.
Erick Ross, a Marine scientist, told the Daily Mail that fish sometimes confuse plastic for food before eating it.
"The plastic does not melt and can block their intestinal tract, and then they cannot feed -- preventing them from consuming food, and starving [them to death]," Ross said.
Many readers expressed outrage over the pollution that was ingested by the fish.
"Just shocking !! Sadly you can only see this getting a lot worse," one Daily Mail reader commented.
"Until reporters have the guts to report which countries are really to blame for dumping all their plastic in the oceans, it is only going to get worse," another wrote.
Others questioned the authenticity of the video.
"I don't believe a word of what they are saying. The way the guts have already been cut open, I think they put all that in before starting the film," one reader wrote.
Meanwhile, a recent study made headlines online after it revealed that pollutants found in water in Hamilton, Canada, began causing fish to work harder to stay alive.
Chemicals that included pharmaceuticals were reportedly found in the waters, according to a study from McMaster University, causing major problems for the planet.
"The evidence is mounting that these sorts of chemicals are having impacts on the natural environment," McMaster University biologist Graham Scott told CBC.
Researchers reportedly conducted the study on several fish -- putting them in cages at different points downstream at the Dundas Wastewater Treatment Plant.
"Specifically we were interested in working in the Dundas Wastewater Treatment Plant because it's so close to Cootes Paradise marsh, which is of course an important natural environment," Scott said.
Fish that were exposed to pollutants needed more oxygen, meaning that they had to work at least 30 percent harder to live.
"It means they won't have as much energy available to support the other important things that a fish needs to do like move around and interact with other fish whether it be for defending territories or for finding mates," Scott said.
"It might not have as much available to get away from predators, to do all the things that a fish needs to do to be a healthy, happy fish in the wild."
