Of all the debris that we dump into the ocean, 75% of it is made of plastic.
And each year more than 8 million tons of plastic ends up in the oceans.
And this number is bound to grow in the coming years due to our growing dependence of plastic goods.
The plastics that end up in the ocean often end up on our beaches, or in animals that consequently die and wash ashore.
This results in money that could have potentially been made through tourism being spent on clean up efforts instead.
It also negatively affects fisheries by killing off the wild stock and decreasing catches.
Ultimately, plastics wreck havoc on marine wildlife, fisheries, and tourism, costing at least $8 billion dollars in damage to marine ecosystems.
At the rate we are going, it’s expected that by 2050, …show more content…

We have also learned that the presence of plastic threatens the health of our coral reefs, of which are already a concern due to ongoing ocean acidification.
One study found that when corals are in contact with plastic, the likelihood of a coral contracting a disease increases from 4% to 89%.
It’s thought that this is due to abrasions from the plastic allowing bacteria and pathogens to readily enter the corals system and/or due to plastic blocking sunlight from reaching the coral, preventing the symbiotic zooxanthellae from photosynthesizing.
As stated in class, plastics can leach toxic chemicals from the seawater and they are broken down into smaller particles by UV light.
These fragments can then be eaten by organisms, allowing the toxins the plastic absorbs to be incorporated into the organism's body and consequently allows these toxins to accumulate in the food chain.
This is particularly important for us because we often eat these animals with plastic and chemicals incorporated into their
