Your Bacon, Egg, and Cheese Sandwiches Have a Hefty Carbon Footprint

Most people know that eating meat, especially red meat—say, hamburgers—is bad for the environment. Raising enough methane-farting, resource-intensive cows to satisfy our cravings for burgers and steaks produces an outsized carbon footprint that plays a significant role in climate change. But what about your breakfast egg-and-cheese? A new study says you should feel guilty about that, too.

Recent findings reported in the journal Sustainable Production and Consumption examine the carbon footprint of 40 different kinds of sandwiches—from the simple ham and cheese to tuna, BLTs, and breakfast sandwiches—both homemade and pre-packaged. Researchers from the University of Manchester calculated the carbon necessary to produce standard recipes, including the agriculture required for the ingredients, the manufacturing of the packaging materials, the refrigeration required to keep the sandwiches cold, and the waste generated. They sourced their estimates from previous studies on the carbon footprint of producing and transporting ingredients like bread, ham, bacon, lettuce, tomato, and canned tuna as well as the energy cost of manufacturing packaging, transporting materials, and taking waste to the landfill.

They found that of all the sandwiches, those that combined pork (or prawns, because prawn and mayonnaise sandwiches are apparently a popular thing) and cheese are the most carbon-intensive. A bacon, egg, and cheese breakfast sandwich clocked in as the most environmentally taxing sandwich of them all, with a carbon footprint of 1441 grams CO2 equivalent—a measurement of the global warming potential—per sandwich. (The diet of the average meat-eater in the UK produces about 7200 grams CO2 equivalent daily. For comparison, if you drive your car four miles, it emits about 1650 grams CO2, roughly.)

Chicken and tuna sandwiches were slightly less carbon-intensive, but vegetarian sandwiches didn't fare as well as you might think—depending on how much and what type of cheese was involved, they could have carbon footprints as high as some of the meat sandwiches.

The researchers suggest that some improvements to the way sandwiches are produced and sold might decrease their carbon footprint by as much as 50 percent. Reducing the amount of meat, eggs, and cheese used, excluding tomato, lettuce, or mayo, reducing packaging, and other changes could all contribute to shrinking a sandwich's carbon footprint. Unfortunately, here's a limit to how much a sandwich's environmental impact can be reduced. You can't really have a BLT without the B, L, or T.

But if you're making it instead of buying it, you're saving a lot of emissions. As you might expect given the environmental cost of packaging, ready-made commercial sandwiches had a much bigger carbon footprint than their homemade counterparts containing the same ingredients—2.2 times larger, in fact.

Just another reason to feel guilty about not bringing your own lunch from home.

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.
