PARIS, Aug 31, 2021 (BSS/AFP) - From endangered freshwater dolphins drowned

by discarded fishing nets to elephants scavenging through rubbish, migratory
species are among the most vulnerable to plastic pollution, a UN report on
the Asia-Pacific region said Tuesday, calling for greater action to cut
waste.

  Plastic particles have infiltrated even the most remote and seemingly-
pristine regions of the planet, with tiny fragments discovered inside fish in
the deepest recesses of the ocean and peppering Arctic sea ice.

  The paper by the UN's Convention on the Conservation of Migratory Species
of Wild Animals (CMS) focused on the impacts of plastic on freshwater species
in rivers and on land animals and birds, which researchers said were often
overlooked victims of humanity's expanding trash crisis.

  It said that because these creatures encounter different environments --
including industrialised and polluted areas -- they are likely at risk of
higher exposure to plastics and associated contaminants.

  Researchers cited estimates that 80 percent of the plastic that ends up in
the oceans originates on land -- with rivers thought to play a key role in
carrying debris out to sea.

  The report comes just days ahead of a major summit of the International
Union for the Conservation of Nature (IUCN), which will include a motion
calling for an end to marine plastic pollution by 2030.

  "Actions to address this global issue have fallen far short of what is
needed," said CMS Executive Secretary Amy Fraenkel.

  "The focus has thus far been on clean up in our oceans, but that is already
too late in the process. We need to focus on solutions and prevention of
plastic pollution upstream." - 'Additional stress' -

  The UN report highlights two regions -- the Ganges and Mekong river basins
-- which together contribute an estimated 200,000 tons of plastic pollution
to the Indian Ocean and the Pacific Ocean every year.

  Discarded fishing gear were found to be major threats.

  Dolphins can become entangled and trapped under water by old nets, with
endangered Irrawaddy Dolphins and Ganges River Dolphins at particular risk.

  The report also said migratory seabirds, such as Black-footed Albatrosses
and Laysan Albatrosses, may not be able to tell plastic from prey when flying
over the ocean and can accidentally eat floating debris.

  This means the plastic could build up in their guts or be passed on to
their chicks when they regurgitate food for them, it said.

  On land, Asian Elephants had also been observed scavenging on rubbish dumps
in Sri Lanka and eating plastic in Thailand, the report noted.

  The report stressed that species in Asia-Pacific face a multitude of
threats, including habitat loss, overfishing, industrial pollution and
climate change.

  "Even if plastic pollution is not the most significant of these stressors,
it can add an additional stress to already vulnerable populations," it said.

  It called for strategies to prevent plastic being dumped in the
environment, reducing waste through better design and recycling, as well as
greater efforts to understand the effects of this pollution on migratory
species.
