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.

Looking to Downsize? You Can Buy a 5-Room DIY Cabin on Amazon for Less Than $33,000

Five rooms of one's own.

If you’ve already mastered DIY houses for birds and dogs, maybe it’s time you built one for yourself.

As Simplemost reports, there are a number of house kits that you can order on Amazon, and the Allwood Avalon Cabin Kit is one of the quaintest—and, at $32,990, most affordable—options. The 540-square-foot structure has enough space for a kitchen, a bathroom, a bedroom, and a sitting room—and there’s an additional 218-square-foot loft with the potential to be the coziest reading nook of all time.

You can opt for three larger rooms if you're willing to skip the kitchen and bathroom.Allwood/Amazon

The construction process might not be a great idea for someone who’s never picked up a hammer, but you don’t need an architectural degree to tackle it. Step-by-step instructions and all materials are included, so it’s a little like a high-level IKEA project. According to the Amazon listing, it takes two adults about a week to complete. Since the Nordic wood walls are reinforced with steel rods, the house can withstand winds up to 120 mph, and you can pay an extra $1000 to upgrade from double-glass windows and doors to triple-glass for added fortification.

Sadly, the cool ceiling lamp is not included.Allwood/Amazon

Though everything you need for the shell of the house comes in the kit, you will need to purchase whatever goes inside it: toilet, shower, sink, stove, insulation, and all other furnishings. You can also customize the blueprint to fit your own plans for the space; maybe, for example, you’re going to use the house as a small event venue, and you’d rather have two or three large, airy rooms and no kitchen or bedroom.

Beavers on Devon's River Otter to Become England's First Permanent Population in Centuries

Beavers were hunted to extinction in England in the 16th century, so locals were surprised to find a group of the mammals living on Devon's River Otter in 2008. Instead of moving the beavers, the Devon Wildlife Trust monitored the population to see how it would interact with the local environment. Now, as The Guardian reports, the government has deemed the beaver reintroduction program a success, meaning the species now has a permanent home in the country for the first time in centuries.

Though the North American beaver is better known, beavers are also native to Europe. Hunting reduced the Eurasian Beaver population to 1200 specimens by 1900. Their numbers have recovered in the years since, but they're still mainly limited to Scandinavia, Germany, France, Poland, and central Russia.

The beaver group currently living on the River Otter likely originated with either an accidental or unauthorized release. When local authorities discovered the beavers were breeding in 2014, they intended to relocate them to protect the local ecosystem. The Devon Wildlife Trust proposed an alternative: Allow the population to live on the river undisturbed for five years, and only remove them if they were proven to cause harm by the end of the trial.

The beavers did not hurt the environment—they actually added several benefits, according to the five-year study. The population, which now consists of 15 family groups, constructed 28 dams throughout the river system. These dams helped slow water flow during floods and contained water during droughts that would normally dry up riverbeds. The beaver-engineered habitat also allowed an increase in the number of water voles, fish, and amphibians.

When the trial officially ends on August 31, the beavers will become permanent residents of Devon in the eyes of the government. They're concentrated on the River Otter for now, but they're expected to expand beyond it, potentially starting new beaver populations in other parts of England for the first time in modern history.
