Want to Save the Environment? Eat Less Meat

It may be time to order a veggie burger instead of a rack of ribs. For years, climate scientists have suggested eating less meat to cut down on greenhouse gas emissions, but the researchers behind a new study say dietary changes are essential to prevent global catastrophe.

The study—published in the journal Nature—is the most comprehensive analysis of how the global food system affects the environment, The Guardian reports. In addition to greenhouse gases being released by livestock, deforestation and water shortages are a couple of other ways that current food production methods hurt the planet. Researchers say there is no easy fix to slow climate change, but reducing our intake of meat is one way that everyone can help out.

“There is no magic bullet,” Marco Springmann, who led the study, tells The Guardian. “But dietary and technological change [on farms] are the two essential things, and hopefully they can be complemented by reduction in food loss and waste."

That doesn’t mean you have to become a vegetarian or vegan, though. Researchers recommend a “flexitarian” diet, which involves occasionally eating meat. For this to make a positive impact, the average global citizen would have to eat 90 percent less pork, 75 percent less beef, and half the number of eggs they normally consume. If you simply can't give up steak, the Climate, Land, Ambition & Rights Alliance (CLARA) recommends consuming just two 5-ounce servings of meat per week. Researchers in the Nature study say beans, nuts, and seeds are all recommended sources of protein.

By their estimates, a global shift towards a flexitarian diet would cut greenhouse gas emissions by 56 percent, and would reduce other environmental impacts by 6 to 22 percent. They say the global food system emitted around 5.7 billion tons of carbon dioxide in greenhouse gas emissions in 2010, in addition to using vast amounts of cropland, fresh water, and fertilizers containing nitrogen and phosphorus (which pollute waterways as agricultural runoff).

“If socioeconomic changes towards Western consumption patterns continue, the environmental pressures of the food system are likely to intensify, and humanity might soon approach the planetary boundaries for global freshwater use, change in land use, and ocean acidification,” researchers write in their paper. In other words, the current food system might not be able to sustain the projected population of 10 billion people in 2060.

The study follows the recent release of a UN report in which scientists warned that we have only 12 years to limit global warming to 1.5 degrees Celsius. Failing to do so would result in more extreme weather events, including drought, floods, and severe heat. If you're looking for other ways to reduce your carbon footprint, try flying less, biking more, and turning down your thermostat. Every bit helps.

Greta Thunberg Named TIME’s Person of the Year for 2019

After receiving a Nobel Peace Prize nomination and launching global strikes for the environment, Greta Thunberg has something new to add to her list of accomplishments. The 16-year-old climate activist has been named TIME's Person of the Year for 2019.

TIME compiles an annual list of individuals and groups that, "for better or for worse [...] has done the most to influence the events of the year." On December 11, TIME revealed that Greta Thunberg was chosen from the finalists to appear on the cover of its Person of the Year issue. According to The Washington Post, the Swedish teenager is the youngest person to receive the honor.

Since leading her first student strike for climate action in 2018, Greta Thunberg has grown a movement of young people fighting for the future of their planet. TIME magazine writes in its profile, "she has succeeded in creating a global attitudinal shift, transforming millions of vague, middle-of-the-night anxieties into a worldwide movement calling for urgent change. She has offered a moral clarion call to those who are willing to act, and hurled shame on those who are not. She has persuaded leaders, from mayors to Presidents, to make commitments where they had previously fumbled."

In 2019, Greta Thunberg morphed from a rising star in activist circles to a household name. She was nominated for the Nobel Peace Prize in March, and in August, she traveled by ship to North America to participate in climate protests and deliver a speech at the United Nations Climate Action Summit.

Over the past decade, TIME's Persons of the Year have included Barack Obama, Mark Zuckerberg, Pope Francis, and Donald Trump. As TIME writes, Thunberg stands out from this field in that she is "not a leader of any political party or advocacy group [...] she’s not a billionaire or a princess, a pop star or even an adult." Despite this, clearly and effectively sharing her message, that “we can’t just continue living as if there was no tomorrow," as she tells the magazine, has been enough to garner global attention.

Ryrkaypiy, Russia, Is Being Overrun By Hungry Polar Bears

Polar bears are becoming a common sight near the village of Ryrkaypiy in northeastern Russia. As CNN reports, nearly 60 bears were spotted looking for food in the area, and experts say climate change is to blame.

Normally around this time of year, Arctic sea ice is thick enough for polar bears to use it as a platform for hunting seals. Temperatures have been warmer than average this year, and without the ice to support them, hungry polar bears are being pushed south into human-occupied territories on land.

According to a statement released by World Wildlife Fund Russia, the bears gathering in Ryrkaypiy are thin-looking and include cubs and adults of various ages. So far, they've been subsisting on walrus carcasses that have been lain on the village's shore since autumn.

No incidents between bears and villagers have been reported yet, but the 500 residents are on guard. Volunteers are now patrolling the town limits and school buses have started picking up children who would normally walk to class.

Prior to this decade, it was unusual to see more than three or five polar bears near Ryrkaypiy at a time. But as climate change drives global warming and melts Arctic sea ice, seeing large groups of polar bears at lower latitudes is no longer an anomaly. Earlier this year, Novaya Zemlya, Russia, declared a state of emergency after more than 50 bears invaded the region. As sea ice becomes more scarce, the circumstances forcing hungry polar bears to share space with people will only get worse.
