50 Years Later | Celebrating Earth Day and its Elements

April 22, 2020

By Madisson Haynes

Every year on April 22, Earth Day is celebrated to honor the world and its elements. The first Earth Day was celebrated 50 years ago in 1970, and since then is recognized every April. Here are a few ways to honor some of Earth's elements, 50 years later.

H20: The Molecule That Made Us

We're starting with the basics on this Earth Day: Water. H20: The Molecule That Made Us dramatically reveals how water underpins every aspect of our existence, courtesy of WGBH. Segments from across the planet, intimate documentary and natural history cinematography combine to uncover dramatic discoveries and compelling characters and deliver important stories about this mysterious molecule.

Killer Floods

All over the world, scientists are discovering traces of ancient floods on a scale that dwarfs even the most severe flood disasters of recent times. What triggered these cataclysmic floods, and could they strike again? In the Channeled Scablands of Washington State, the level prairie gives way to bizarre, gargantuan rock formations. Killer Floods, courtesy of NOVA, will answer some of those pressing questions.

Follow the Water

Traveling by bike, on foot and in a canoe, photographer Mike Forsberg and filmmaker Peter Stegen follow a mythical drop of water 1,300 miles through three states in Follow the Water. Using iPhones, Go-Pros and underwater cameras they share how it feels to get close to the flow of the water — to taste it, touch it, and struggle to understand it.

When We Tamed Fire

The ability to make and use fire has fundamentally changed the arc of our evolution. The bodies we have today were, in many ways, shaped by that time when we first tamed fire. When We Tamed Fire, courtesy of Eons, dives into that time.

Fire in Paradise

After the devastating Camp Fire, FRONTLINE examines who’s to blame and why it was so catastrophic. With accounts from survivors and first responders, the documentary tells the inside story of the most destructive fire in California's history, its causes and the impact of climate change.

Flying Through the Amazon's Prehistoric Air

Flying Through the Amazon's Prehistoric Air

The Amazon rainforest covers over two million square miles of the South American landmass. It absorbs so much carbon and produces so much oxygen that scientists call it "the lungs of the Earth." Flying Through the Amazon's Prehistoric Air, courtesy of Environment, show how researchers from Pacific Northwest National Laboratory in Richland, Washington have encountered a bank of air so pure it changes our understanding of how clean the atmosphere can be.

I Am a Universe Photographer

With the help of high-powered telescopes around the world, scientists can observe and photograph far-flung astronomical phenomena. I Am a Universe Photographer, courtesy of Indie Alaska, shows how Dr. Travis Rector has been capturing images of distant galaxies and nebulae for over 20 years.

The Planets: Inner Worlds

The rocky planets — Mercury, Venus, Earth and Mars — were born of similar material around the same time. Yet only one of them supports life. Were Earth's neighbors always so extreme? And is there somewhere else in the solar system life might flourish? The Planets: Inner Worlds, courtesy of NOVA, answers these questions.
