Plastic should be banned
part-2
Attracts other pollutants
90% of all the trash floating on the ocean
surface is plastic.
Plastic waste causes extensive harm to animals who are killed by plastics every
year, from birds to fish. Nearly 700 species, including endangered ones, are
known to have been affected by plastics.

Plastic trash is found in the guts of more
than 90% of the world’s sea birds, in the stomachs of more than half of the
world’s sea turtles, and it’s even choking the life out of whales. In a 2006 report, Plastic Debris in the World’s Oceans, Greenpeace
stated that at least 267 different animal species are known to have suffered
from entanglement and ingestion of plastic debris. According to the National
Oceanographic and Atmospheric Administration, plastic debris kills an estimated
100,000 marine mammals annually, as well as millions of birds and fishes.
The United
Nations Joint Group of Experts on the Scientific Aspects of Marine Pollution
(GESAMP), estimated that land-based sources account for up to 80 percent of the
world’s marine pollution, 60 to 95 percent of the waste being plastics debris.
Turtles
are well-known victims of plastic waste. When in the presence of plastic, they
sometimes ingest it. The material then becomes stuck in their intestines,
causing death in the worst cases. The slow endangerment of the sea turtles
species can be linked to human pollution, especially plastic pollution.
Plastics not only have adverse effects on our natural habitats, but have also been found to be responsible for the death of many animals, mainly on account of the suffocation encountered on eating them or the plastic bags in the water may get wrapped around marine animals.
Most of the deaths to animals are caused by entanglement or
starvation. Seals, whales, turtles, and other animals are strangled by
abandoned fishing gear or discarded six-pack rings.
Attracts other pollutants
plastic acts like a magnet for
a range of other poisons and pollutants we have spilled into the natural
world. Chemicals in plastic which give
them their rigidity or flexibility (flame retardants, bisphenols, phthalates
and other harmful chemicals) are oily poisons that repel water and stick to
petroleum-based objects like plastic debris. So, the toxic chemicals that
leach out of plastics can accumulate on other plastics. This is a serious
concern with increasing amounts of plastic debris accumulating in the world's
oceans.

Threat To Animal Life
The marine species are more affected to
plastic pollution as the litter either directly thrown to sea water or from
landfill it end up to sea water.
The marine
animals either entangled in plastic or mistaken it for food, it significantly
raise the mortality rate of animals, and it is found that even extremely remote
ocean of the Earth is not free from the plastic pollution. It effect from the microscopic
amphipods to the animals as big as blue whales. It even harms the coral that
sustain coral reefs.
“Marine
plastic litter pollution is already affecting more than 800 marine species
through ingestion, entanglement and habitat change,” says head of UN
Environment’s coral reef unit, Jerker Tamelander.
Between 8 and 12 million tons of plastic enter the
ocean annually.
“That’s like one garbage truck load every 60 seconds,”
said Cassia Patel, project manager at Oceanic Global, a nonprofit that helps
organizations and people go plastic-free.
It is estimated that at this
rate of accumulation of plastic in the world’s ocean will lead to a day when
there will be more plastic than fish by 2050 and 99 per cent of all the
seabirds on the planet will have consumed some. It is thought the sea now
contains some 51 trillion microplastic particles – 500 times more than stars in
our galaxy.
Unsurprisingly, gulping down all this
indigestible poison instead of food is bad for their health. So far, it is
known that marine litter harms more than 600 species amid what some regard as the beginning of the
sixth mass extinction of life on Earth.
Plastics not only have adverse effects on our natural habitats, but have also been found to be responsible for the death of many animals, mainly on account of the suffocation encountered on eating them or the plastic bags in the water may get wrapped around marine animals.
According to a
study by Plymouth University, one third of the fish caught in the UK had
plastic inside. The effect of eating these plastic contaminated fish is for the
most part unknown, but the risk was substantial enough to warrant a warning of
increased risk to human health and safety by the European Food Safety Authority
in 2016.
Sea birds and fish have a hard time distinguishing plastic
from food. When
they eat the stuff, they cannot digest it, and eventually die with bellies
so full of plastic that no food or water can pass through them.

Microplastics
have been found in more than 100 aquatic species, including fish, shrimp, and
mussels destined for our dinner plates. In many cases, these tiny bits pass
through the digestive system and are expelled without consequence. But plastics
have also been found to have blocked digestive tracts or pierced organs,
causing death. Stomachs so packed with plastics reduce the urge to eat, causing
starvation.
Plastics
have been consumed by land-based animals, including elephants, hyenas, zebras,
tigers, camels, cattle, and other large mammals, in some cases causing death.
Tests have
also confirmed liver and cell damage and disruptions to reproductive systems,
prompting some species, such as oysters, to produce fewer eggs. New research
shows that larval fish are eating nanofibers in the first days of life, raising
new questions about the effects of plastics on fish populations.
