There's Only One Carbon Negative Country in the World (Here's How They Do It)

In 2017, the small nation of Bhutan became the first and only carbon negative country in the world. That's right: not carbon neutral, carbon negative.

In an article on the subject, the Climate Council—an independent, Australia-based nonprofit organization dedicated to educating the public on matters related to climate change—defines carbon negative status as occurring when a country's carbon emissions are not only offset, but are actually in the negative due to the generation and exportation of renewable energy. There are several reasons for this impressive feat.

Bhutan—a small, landlocked country in the middle of the Himalayas—has a population of approximately 813,000 and produces 2.2 million metric tons of carbon dioxide per year. The country is 72 percent forest, and those forests trap more than three times their carbon dioxide output through a process called carbon sequestration, the long-term storage of carbon in plants, soil, and the ocean. This means that Bhutan is a carbon sink: It absorbs more carbon than it releases as carbon dioxide. Specifically, Bhutan is a carbon sink for more than 4 million tons of CO2 each year. In addition, the country exports most of the renewable electricity generated by its rivers, which is equivalent to 6 million tons of CO2.

Bhutan is also exceptionally environmentally friendly. This is partly because it takes a holistic view of development, measuring it with the Gross National Happiness Index instead of the Gross Domestic Product Index, like most countries. Instead of only prioritizing economic improvement, Gross National Happiness balances it with sociocultural and environmental improvement. The eco-conscious country invests in sustainable transport, subsidizes electric vehicles, and has an entirely paperless government.

Bhutan has pledged to remain carbon neutral for all time, and it's safe to say it's doing pretty well so far.

What Would It Cost to Operate a Real Jurassic Park?

As the Jurassic Park franchise has demonstrated, trapping prehistoric monsters on an island with bite-sized tourists may not be the smartest idea (record-breaking box office numbers aside). On top of the safety concerns, the cost of running a Jurassic Park would raise its own set of pretty pricey issues. Energy supplier E.ON recently collaborated with physicists from Imperial College London to calculate how much energy the fictional attraction would eat up in the real world.

The infographic below borrows elements that appear in both the Jurassic Park and Jurassic World films. One of the most costly features in the park would be the aquarium for holding the massive marine reptiles. To keep the water heated and hospitable year-round, the park would need to pay an energy bill of close to $3 million a year.

Maintaining a pterosaur aviary would be an even more expensive endeavor. To come up with this cost, the researchers looked at the yearly amount of energy consumed by the Eden Project, a massive biome complex in the UK. Using that data, they concluded that a structure built to hold winged creatures bigger than any bird alive today would add up to $6.6 million a year in energy costs.

Other facilities they envisioned for the island include an egg incubator, embryo fridge, hotel, and emergency bunker. And of course, there would be electric fences running 24/7 to keep the genetic attractions separated from park guests. In total, the physicists estimated that the park would use 455 million kilowatt hours a year, or the equivalent of 30,000 average homes. That annual energy bill comes out to roughly $63 million.

Keep in mind that energy would still only make up one part of Jurassic Park's hypothetical budget—factoring in money for lawsuits would be a whole different story.

This Plant Can Burn Your Skin With its Sap—And It May Be Coming to Your Neighborhood

It's huge, it's extremely dangerous, and it's spreading. The giant hogweed (Heracleum mantegazzianum) contains a corrosive sap that causes severe rashes, third-degree burns, and even permanent blindness if you get the photosensitive chemicals on your skin or in your eyes, Science Alert reports.

The noxious, invasive weed was just identified in Clarke County, Virginia, near the Massey Herbarium at Virginia Tech. That brings the number of states it's been spotted in to 11, including Washington, Oregon, Illinois, Michigan, North Carolina, Pennsylvania, New York, Connecticut, Massachusetts, and Maine. Beyond the U.S., it has taken root all over the world, from the UK to Iceland to Australia.

Similar to the common but slightly less dangerous cow parsnip, giant hogweed is native to Central Asia and was first brought to North America in the early 1990s as an ornamental plant, its unique shape making it popular among gardeners. But it soon became invasive: Once it’s established in an area, it can take up to five years to eradicate a colony.

Now the plant is considered a public health concern. Hogweed can cause a reaction known as phytophotodermatitis when it comes into contact with skin that is subsequently exposed to UV rays—but the effects of hogweed are much more severe. A painful blister can develop within hours and last for months; the exposed skin can remain sensitive to sunlight for years even after the blisters heal.

Hogweed can be difficult to distinguish from the cow parsnip, and the plant is often misidentified. First, check for height: Hogweeds are typically taller than 8 feet, while cow parsnip tends to be 5 to 8 feet tall. Hogweed stems are green with purple specks and coarse white hairs, while parsnip stems are green with fine white hairs. For more tips and photos, check out the New York Department of Environmental Conservation’s guide.

If you see a plant you think might be a giant hogweed, take a few photos and send them to your state's department of agriculture to identify—and whatever you do, don't touch it.
