Conservationists and veterinarians have warned that plastic waste in an open landfill in eastern Sri Lanka is killing elephants, after two more were found dead at the site.
Di 20 elephants have died over the last eight years after consuming plastic in the dump in Pallakkadu village in Ampara district, di 130 miglia (210km) east of the capital, Colombo.
Examinations of the dead animals showed they had swallowed large amounts of nondegradable plastic, said Nihal Pushpakumara, a wildlife veterinarian.
“Polythene, food wrappers, plastic, other non-digestibles and water were the only things we could see in the postmortems. The normal food that elephants eat and digest was not evident," Egli ha detto.
Elephants are revered in Sri Lanka but also endangered. Their numbers have dwindled from about 14,000 in the 19th century to 6,000 nel 2011, according to the country’s first elephant census.
They are increasingly vulnerable because of the loss and degradation of their natural habitat. Many venture closer to human settlements in search of food, and some are killed by poachers or farmers angry over damage to their crops.
Hungry elephants seek out the waste in the landfill, consuming plastic as well as sharp objects that damage their digestive systems, Pushpakumara said. “The elephants then stop eating and become too weak to keep their heavy frames upright. When that happens, they can’t consume food or water, which quickens their death," Egli ha detto.
Nel 2017, the Sri Lankan government announced it will recycle the garbage in dumps near wildlife zones to prevent elephants from consuming plastic waste. It also said electric fences would be erected around the sites to keep the animals away. But neither strategy has been fully implemented.
Ci sono 54 waste dumps in wildlife zones around Sri Lanka, with about 300 elephants roaming near them, according to officials. The waste management site in Pallakkadu was set up in 2008 with aid from the EU. Rubbish from nine nearby villages is dumped there but not recycled.
Nel 2014, the electric fence protecting the site was struck by lightning and authorities never repaired it, allowing elephants to enter and rummage through the dump. Residents say elephants have moved closer and settled near the waste pit, causing fear among nearby villagers.
Many use firecrackers to chase the animals away when they wander into the village, and some have erected electric fences around their homes.
But the villagers often did not know how to install the electric fences safely and “could endanger their own lives as well as those of the elephants”, said Keerthi Ranasinghe, a village councillor.
“Even though we call them a menace, wild elephants are also a resource. Authorities need to come up with a way to protect both human lives and the elephants that also allows us to continue our agricultural activities," Egli ha detto.
