Electric Vehicles Could Easily Replace Gas-Powered Cars

24 Aug

Electric vehicles like those pictured could easily replace gas vehicles, some argue.

Electric vehicles, or EVs, are the center of a lot of debate about carbon emissions and consumer needs. It’s pretty obvious that replacing traditional combustion engine cars with EVs would do a lot to help reduce emissions. In fact, one study found that replacing traditional cars with EVs would suffice for about 90 percent of […]

Largest Extinction Event on Earth Caused by Animals

22 Aug

Sea cucumbers are among the earliest multicellular life forms on earth.

The largest mass extinction in Earth’s history happened 540 million years ago, and is known as the end-Ediacaran extinction. New fossil evidence from Namibia has helped to shine some light on what caused that extinction: animals. Single-celled organisms dominated the planet until about 600 million years ago until the first multicellular organisms, known as Ediacarans, […]

European Salmon Stocks Were Reduced by Medieval Water Mills

19 Aug

Medieval water mills may have harmed European salmon populations

Human activity has been impacting the environment for as long as there have been humans. From our prehistoric ancestors hunting species to extinction, to modern carbon levels, pretty much everything we’ve done has had an impact. An example of this is shown by recent research on salmon stocks in the Netherlands. According to archival research […]

Gorillas Found Dismantling Poacher Traps

17 Aug

A family of gorillas. Juvenile gorillas have been dismantling poacher traps.

Poachers in Rwanda often make use of simple traps to catch antelopes and other animals. The traps generally consist of a noose tied to a bamboo branch, which is held down with a rock while the noose is hidden. Yes, just like in a cartoon. Although they aren’t meant to capture primates, they sometimes do, and […]

Using Candy and Drones to Save Black-footed Ferrets

15 Aug

A black-footed ferret,. This animal is endangered and getting more so thanks to a disease carried by its prey.

The black-footed ferret has been endangered for quite some time. They were actually listed as extinct in 1979, but a population was rediscovered in 1981, and as of 2011 there were about 1,000 of them in the wild. Since then, that number has dropped to about 300. That’s a 70 percent loss over five years, […]

Land Temperatures Will Keep Rising Even if We Cap Average Temperatures

12 Aug

A desert landscape

For years, climate scientists have been making the case that we can and must limit the increase of the average global temperature to no more than two degrees Celsius compared to temperatures before widespread industrialization. A recent study finds that may be harder to do than we expected. The study, published in the journal Scientific […]

MIT Researchers Develop System for More Efficient Biofuel Production

11 Aug

A biofuel production facility

Biofuels are a potential way to help the environment because they produce less carbon dioxide than fossil fuels, and they’re sustainable. Unfortunately, the process by which they are made can be inefficient. Biofuels are a byproduct of bacteria eating such things as corn or sugarcane, from which they get necessary nitrogen. The problem is that […]

Deep-Sea Mining Could Threaten Intricate Ecosystems

10 Aug

An underwater cave with a sea floor and a tree branch

  Thanks to some quirks of geology, there are large nodules of metallic minerals under the sea floor in the equatorial Pacific Ocean. Deep-sea mining operations are planning to target these nodules in order to seek out potential sources of copper, nickel, cobalt, and manganese, and perhaps other metals. However, because such operations can have significant […]

Greenland Glacier Melt Alters Currents Down to the Gulf Stream

20 Jul

Icebergs in Illulissat Icefjord, Greenland are evidence of ice sheets melting at an accelerated rate and impacting the salinity of seawater surrounding Greenland.

The melting of glaciers around the world due to human caused climate change is something that a lot of us are familiar with. We’ve heard the arguments about how sea levels will rise and the like, but there are other, less discussed problems that could end up impacting the world sooner rather than later. Take […]

The Business World Starts to See that Green is Good

18 Jul

Big business is learning that green initiatives are good for their bottom line.

  It’s easy to think of big business as constantly being at odds with environmental preservation. But more and more businesses are actually finding it profitable to care for the land around them. Whether it’s a utility firm implementing carbon offsets, a transportation company restoring wetlands, or a private equity firm investing in the ecological […]
