9 Nara Deer Found Dead After Eating Plastic in Sacred Japanese Sanctuary
The global plastic crisis has invaded a sacred sanctuary in Japan. Nine deer in Nara Park that have died since March were revealed to have massive amounts of plastic bags and food wrappers in their digestive tract.
Three of the nine deaths were attributed directly to digestive issues from eating the plastic, said Yoshitaka Ashimura, secretary general of the conservation group Nara Deer Preservation Foundation, as CNN reported. In one deer, researchers from the conservation group found 9.5 pounds of plastic in its digestive system, according to Newsweek.
In March, the group posted a photo of 7 pounds of plastic pulled from another deer's stomach.
Nara Park, just east of Osaka, is a Unesco World Heritage Sight and home to over 1,000 Sika deer, which have been classified as a national treasure and are, therefore, protected by law. Those legal protections have tamed the deer that roam the park freely without fear of predators. Visitors to the park are allowed to feed the deer with digestive and sugar-free deer crackers, known locally as shika sembei, which are sold in nearby shops and do not have plastic wrapping, according to Japan Today.
Yet, some visitors will feed the deer other treats, prompting local authorities to ask people to stop offering unauthorized snacks, as Newsweek reported.
The deer eat plastic after watching tourists take food out from bags and wrappers, said Rie Maruko, a veterinarian with the Nara Deer Preservation Foundation, as Japan Today reported. He added that the deer learn that bags contain food and they are tempted by the scents coming off discarded food packaging.
Deer are ruminants with a four-chambered stomach that allows them to digest grasses and derive their nutrition from it. When the first chamber fills with non-digestible items, like plastic, they are not able to regurgitate, digest or ingest new food. Unable to digest, the animal weakens and withers away until it finally dies.
"The deer that died were very skinny and I was able to feel their bones," Maruko said, according to Japan Today. "Please do not feed them anything other than the designated shika sembei."
The Nara Deer Preservation Foundation has upped its efforts to warn tourists about the dangers of bringing plastic bags and food wrappers into the park. Additionally, new signs posted in several languages this spring show people how to feed the deer, but they have not been effective in reducing plastic waste, said Ashimura, as CNN reported. The local government said it will take additional steps to protect the deer.
The conservation group launched a cleanup campaign on Wednesday. More than 100 volunteers collected over 116 pounds of trash around the park. Sixty percent of it was plastic.
"The amount of plastic garbage we collected was over our expectation," Ashimura said, as CNN reported. "We are concerned that a mere clean up won't solve the issue. It's important that the visitors won't throw them away to begin with to protect deer."

More long-finned pilot whales were found stranded today on beaches in Tasmania, Australia. About 500 whales have become stranded, including at least 380 that have died, the AP reported. It is the largest mass stranding in Australia's recorded history.

By 2030, almost a third of all the energy consumed in the European Union must come from renewable sources, according to binding targets agreed in 2018. Sweden is helping lead the way.

Naturally Warm<p>54% of Sweden's power comes from renewables, and is helped by its geography. With plenty of moving water and 63% forest cover, it's no surprise the <a href="https://sweden.se/nature/energy-use-in-sweden/#" target="_blank">two largest renewable power sources</a> are hydropower and biomass. And that biomass is helping support a local energy boom.</p><p>Heating is a key use of energy in a cold country like Sweden. In recent decades, as fuel oil taxes have increased, the country's power companies have turned to renewables, like biomass, to fuel local 'district heating' plants.</p><p>In Sweden these trace their <a href="https://www.sciencedirect.com/science/article/pii/S0360544217304140#fig3" target="_blank">origins back to 1948</a>, when a power station's excess heat was first used to heat nearby buildings: steam is <a href="https://www.sciencedirect.com/topics/engineering/district-heating-system" target="_blank">forced along a network of pipes</a> to wherever it's needed. Today, there are around 500 district heating systems across the country, from major cities to small villages, providing heat to homes and businesses.</p><p>District heating used to be fueled mainly from the <a href="https://www.sciencedirect.com/science/article/pii/S0360544217304140" target="_blank">by-products of power plants</a>, waste-to-energy plants and industrial processes. These days, however, Sweden is bringing more renewable sources into the mix.

Sweden is using smart grids to turn buildings into energy producers. Huang et al/Elsevier
Energy ‘Prosumers’<p>But Sweden doesn't stop at village-level heating solutions. Its new breed of energy-generation takes hyper-local to the next level.</p><p>One example is in the city of Ludivika where 1970s flats <a href="https://www.buildup.eu/sites/default/files/content/transforming-a-residential-building-cluster-into-electricity-prosumers-in-sweden.pdf" target="_blank">have recently been retrofitted with the latest smart energy technology</a>.</p><p>48 family apartments spread across 3 buildings have been given photovoltaic solar panels, thermal energy storage and heat pump systems. A micro energy grid connects it all, and helps charge electric cars overnight.</p><p>The result is a cluster of 'prosumer' buildings, producing rather than consuming enough power for 77% of residents' needs. With <a href="http://www.diva-portal.org/smash/get/diva2:1232060/FULLTEXT01.pdf" target="_blank" rel="noopener noreferrer">high levels of smart meter usage</a>, it's a model that looks set to spread across Sweden.</p>

The system is not only more efficient, but bills have fallen.</p><p>Smart energy developments like those in Hyllie, Ludivika, and renewable-driven district heating, offer a radical alternative to the centralized energy systems many countries rely on today.</p><p>The EU's leaders have a challenge: how to generate 32% of energy from renewables by 2030. Sweden offers a vision of how technology and local solutions can turn a goal into a reality.</p>
