When it comes to mass extinctions, you probably imagine giant volcanic eruptions or asteroids raining fire from the sky, but sometimes these events can have some unexpected causes. Hosted by: Michael Aranda

You’d never tell just by staring out from a sandy beach, but the coasts are gradually getting darker, and the effects of this darkening are only beginning to be understood.

Hank talks about a few - maybe crazy, maybe reasonable - geoengineering schemes that some scientists have come up with in order to "fix" climate change, including designer clouds, ocean fertilization, and stratospheric shading with...

For weeks now, thousands of dead fish, turtles, manatees, and dolphins have been washing up on beaches in southwest Florida.

Hank talks about the last major way humans are impacting the environment in this penultimate episode of Crash Course Ecology. Pollution takes many forms - from the simplest piece of litter to the more complex endocrine distruptors - and...

Florida's coastline is being threatened by toxic algal bloom, and it seems to be getting worse every year, the Tampa Bay Times reports.

Chile's growing red tide crisis is threatening not only marine life but also communities that depend on the sea for their livelihood. Red tide is a commonly recurring phenomenon in Chile, but the outbreak that has grown rapidly along the...

Water quality for swimming can be compromised by high levels of bacteria and harmful blooms of algae, in lakes and on ocean beaches. These can cause illness in people, along with harm to other creatures and plants. In this film, we look...

Learn the basics about the Haber Process and its environmental implications.

This video provides an overview of the element phosphorus and its significance in various aspects of life. Phosphorus is a vital element found in the human body and plays a crucial role in DNA, RNA, and energy transfer in cells....

What happens when fertilisers get washed into lakes and rivers? A process called eutrophication. Learn all about it in this video. Eutrophication is the process that can happen in a water body, like a river or a lake, when too many...

Over the summer some municipalities in the region didn’t have drinking water because of the amount of blue-green algae in the lakes and rivers. They’re asking the Quebec government to step in.
