NASA's Time Lapse Video Shows Humanity's Impact on the Earth

How much of an impact can billions and billions of people make on the environment? Well, if you watch the video below from Vox, you'll see that in a mere 40 years, human activity can leave quite the mark.

These images are courtesy of NASA and the U.S. Geological Survey's Landsat satellite program that the space agency launched in 1972 with the sole intention of studying our planet's surface and how its been changing over time. According to Vox, the satellite takes pictures of the entire surface of the planet every 18 days and orbits the Earth 14 times a day.

In the video, photos taken over the last four decades have been strung together to show humanity's footprint on five different locations. From the shocking deforestation of Rondônia, Brazil (where the area's global beef exports have mowed down enough trees to fill the state of West Virginia), to the rampant water use in the Aral Sea causing a loss of 60,000 fishery jobs due to rising salt levels.

You'll also see how the the dirty energy industry has literally stripped away Wyoming's natural resources, and how much the Larsen B Ice Shelf has collapsed due to climate change. And in the GIF above from Vox, notice how the increasing number of golf courses and artificial lakes in rapidly growing Las Vegas are an ironic harbinger of the area's relentless drought.

It's clear that we must all change our ways and act now before it gets any worse. Check out the haunting footage here:

EPA: Perchlorate in Drinking Water Can Harm Fetal Brain Development

By Tom Neltner

Pursuant to a consent decree with the Natural Resources Defense Council (NRDC), the U.S. Environmental Protection Agency (EPA) is developing drinking water regulations to protect fetuses and young children from perchlorate, a toxic chemical that inhibits the thyroid's ability to make the hormone T4 essential to brain development. The rulemaking is part of a long process that began in 2011 when the agency made a formal determination that Safe Drinking Water Act standards for perchlorate were needed. Under the consent decree, EPA should propose a standard by October 2018.

In the latest step in that process, EPA's scientists released a draft report in September that, at long last, answers questions posed by its Science Advisory Board in 2013: does perchlorate exposure during the first trimester reduce production of T4 in pregnant women with low iodine consumption? Does reduction in maternal T4 levels in these women adversely affect fetal brain development? According to EPA's scientists, the answers are Yes and Yes.

Ditch Plastic Lunches: Stand Up for Zero-Waste Schools

  • Carrots in a Ziploc
  • Grapes in a bag
  • Sandwich in saran wrap, with a "fresh daily" tag
  • Water bottle snuggled by an extra pair of socks
  • Plastic straw
  • Chips to gnaw
  • Juice in a box

That's an average American kids lunch stuffed in a school bag, with enough plastic packaging to wallpaper the classroom. Once it comes to school lunch, we don't practice what we preach, so let's unpackage what we teach.

Trump's 'Hold' on Elephant Trophies May Not Be Enough

As many of you may have heard by now, President Donald Trump tweeted, and Interior Sec. Ryan Zinke reiterated, a decision late Friday night to put elephant trophy imports from Zimbabwe "on hold" out of the belief that "conservation and healthy herds are critical."

This follows the administration's decision, on Thursday, to allow such imports after finding Zimbabwe's management of its elephant population "enhances the survival of the species" (referred to as a "positive enhancement finding") under the U.S. Endangered Species Act. The announcement reversed the Obama-era suspension on such imports due to finding the opposite: that Zimbabwe was NOT successfully managing its elephant population.

Fracking Chemicals Remain Secret Despite EPA Knowledge of Health Hazards

By Tasha Stoiber

The U.S. Environmental Protection Agency (EPA) knows that dozens of the chemicals used in fracking pose health hazards. The agency not only allows their use, but also lets the oil and gas industry keep the chemicals secret, according to a new report.

Between 2003 and 2014 the EPA identified health hazards for 41 chemicals used in fracking, according to a report from the Partnership for Policy Integrity and Earthworks, based on documents obtained through a Freedom of Information Act request. Fracking is the injection of a chemical slurry into drilling sites to free up underground oil and gas deposits. Hazards from the chemicals used included irritation to eyes and skin; harm to the liver, kidney and nervous system; and damage to the developing fetus.

Global Warming Timeline, Political Will: Top Questions After COP23

As the world increasingly looks to be on track for a catastrophic 3°C of global warming, world leaders and diplomats gathered in Bonn, Germany to turn the Paris agreement into a set of rules.

In that sense the 23rd Conference of the Parties (COP23), which concluded on Saturday, accomplished its goal of keeping the process alive by setting up the rules that will be finalized next year in Poland. But the conference also kicked a number of issues down the road. The round of climate talks heard repeated calls for a more ambitious approach to slashing carbon emissions but did not initiate any conclusive solutions, though it should be noted that no major decisions were expected.

Florida Schools' Food Waste Program: A Win-Win to Fight Hunger and Save the Environment

You've probably heard the unsettling stories of school cafeteria workers throwing away students' lunches over unpaid lunch bills, but schools in Orange County, Florida have come up with a genius solution to not only help feed hungry students and their communities, but to also cut down on food waste.

For the past two years, about 20 public elementary schools in the Florida county have been using "share tables" to great effect, the Orlando Sentinel reported. The program allows kids to place their unwanted food on designated tables so others can eat them. This means the food doesn't have to be thrown out. Instead, fellow students who are still hungry can just grab the food themselves off the tables.

Record Number of Americans 'Very Worried' About Climate Change

As someone who writes about the environment on a near-daily basis, the fact that a large chunk of Americans (about one in eight) reject the near scientific consensus of climate change can be a tough pill to swallow.

But after a year of record-breaking heatwaves, massive wildfires in the west, and a string of destructive hurricanes, it appears that my fellow U.S. citizens are waking up to the realities of our hot, new world, according to the latest nationally representative survey from the Yale Program on Climate Change Communication and the George Mason University Center for Climate Change Communication.

Nursery Bans Glitter, Calls on Others to Follow Their Example

By Imogen Calderwood

Glitter is great, right? Particularly now that it's getting dark and cold and a bit depressing outside.

But, as much as we love glitter for making everything look festive, a chain of children's nurseries in the UK might actually have a point.
