According to the United Nations, at least 800 species worldwide are affected by marine debris, and as much as 80 percent of that litter is plastic. … Fish, seabirds, sea turtles, and marine mammals can
become entangled in or ingest plastic debris
, causing suffocation, starvation, and drowning.
Why is marine litter a problem?
Marine species
ingest or are entangled by plastic debris
, which causes severe injuries and deaths. Plastic pollution threatens food safety and quality, human health, coastal tourism, and contributes to climate change.
How does littering pollute the ocean?
When debris—plastic bags, bottles, cigarette butts, etc—is thrown on the ground,
it gets washed into storm drains and directly into our waterways
. In addition to potentially choking, suffocating, or disabling aquatic life like ducks, fish, turtles, and birds, litter decreases oxygen levels in the water when it decays.
How does plastic pollution affect marine life?
The most visible and disturbing impacts of marine plastics are the
ingestion, suffocation and entanglement of hundreds of marine species
. Marine wildlife such as seabirds, whales, fishes and turtles, mistake plastic waste for prey, and most die of starvation as their stomachs are filled with plastic debris.
How does ocean pollution affect marine life?
It is estimated that up to 13 million metric tons of plastic ends up in the ocean each year—the equivalent of a rubbish or garbage truck load’s worth every minute. Fish, seabirds, sea turtles, and marine mammals
can become entangled in or ingest plastic debris
, causing suffocation, starvation, and drowning.
Why is littering bad for humans?
In addition to water and soil pollution, litter can also pollute the air. Researchers estimate that more than 40% of the world’s litter is burned in the open air, which can release
toxic emissions
. These emissions can cause respiratory issues, other health problems, and even be a starting base for acid rain.
What inventions already exist to clean the ocean?

Why is plastic bad for humans?
Microplastics entering the human body via direct exposures through ingestion or inhalation can lead to an array of
health impacts
, including inflammation, genotoxicity, oxidative stress, apoptosis, and necrosis, which are linked to an array of negative health outcomes including cancer, cardiovascular diseases, …
Why is plastic bad?
Plastic debris, laced with chemicals and often ingested by marine animals,
can injure or poison wildlife
. Floating plastic waste, which can survive for thousands of years in water, serves as mini transportation devices for invasive species, disrupting habitats.
How much plastic will be in the ocean in 2050?
Starting with an estimate that 150 million tonnes of plastic are already polluting the world’s oceans, and that “leakage” adds at least 9.1 million tonnes more each year — a figure that is said to be growing by five per cent annually — the MacArthur report calculates there will be
850-950 million tonnes
of ocean …

How can marine pollution be reduced?
Wherever you live, the easiest and most direct way that you can get started is by
reducing your own use of single-use plastics
. Single-use plastics include plastic bags, water bottles, straws, cups, utensils, dry cleaning bags, take-out containers, and any other plastic items that are used once and then discarded.
What diseases can littering cause?
- Parasitic Infections. …
- Lung Infections. …
- Skin infections. …
- HIV and Hepatitis B and C Viruses. …
- Candida. …
- Meningitis. …
- Bacteremia.
What would happen if we stopped littering?
When waste isn’t properly disposed of in the correct bins there’s less chance of recycling. The litter ends up in our water systems, it ends up in the digestive tracts of our wildlife,
it ends up smothering plants
, and reduces air quality due to smell and toxic chemical vapors coming from it.
Does littering affect climate change?
When organic waste decomposes, carbon dioxide and methane gas is created. … Thus, rubbish sent to a dumpsite or landfill represents a significant amount of greenhouse gases already emitted to the atmosphere and have contributed to
climate
change.
