What if you could take something as tiny as a grain of sand — and as common as a glass bottle — and use it to tackle the climate crisis? Waste alchemist Franziska Trautmann shares how the spark of an idea turned into a large-scale...

When Americans no longer want a car, laptop or clothes, where do some of those goods go? Most end up in the Global South, where millions of people depend on repairing, dismantling or selling them for a livelihood. Environmental groups...

An estimated 20 million people are thought to earn their livelihoods in the global waste industry by collecting, disposing, repairing or repurposing a wide range of materials and products. However, the cost and consequences of handling...

If everyone would just put more in the recycling bin instead of the trash can, the world would be a better place. Right? Well, that’s not exactly true. For many items that end up in the recycling bin, you’ve actually created more trash...

When you think about the impact of climate change on the circle of life, you likely picture polar bears or Bengal tigers struggling in new conditions. But the impacts on the world go all the way down to the tiniest creatures who do some...

Some of science's most interesting discoveries happened totally on accident! From insects to infections, and polymers to pacemakers, we've accidentally discovered some pretty cool stuff. Watch this new episode of SciShow, hosted by...

Some might call sand coarse, rough and irritating, but there’s no denying that it’s used everywhere: from glass to asphalt, sand is a key ingredient for all sorts of materials in construction and technology. But this heavy reliance on...

Everyone loves bananas. But because banana trees die and grow back every year, researchers want to find ways to recycle all that biomass -- from bioplastic, to solar panels, to skateboards.

About one-third of all the food produced for human consumption is lost or wasted, according to the United Nations. But several years ago, South Korea instituted a law that requires residents to separate food waste from other garbage and...

Natsai Audrey Chieza is a designer on a mission -- to reduce pollution in the fashion industry while creating amazing new things to wear. In her lab, she noticed that the bacteria Streptomyces coelicolor makes a striking red-purple...

Capt. Charles Moore of the Algalita Marine Research Foundation first discovered the Great Pacific Garbage Patch -- an endless floating waste of plastic trash. Now he's drawing attention to the growing, choking problem of plastic debris...

Is there any better way to create new energy than to make it out of consumed energy sources?

Join SciShow as we explore what happens to your stuff after you toss it into the little green bin with the arrows on it.

Every day, humans literally flush a valuable resource down the toilet: nitrogen. But there are some animals that have figured out a way to recycle the extra nitrogen in their bodies by moving it not to their livers, but to their mouths!

Join Jessi and Squeaks as they talk about some things you can do to make the earth a better place!

Death is what fungi are all about. By feasting on the deceased remains of almost all organisms on the planet, converting the organic matter back into soil from which new life will spring, they perform perhaps the most vital function in...

Though not everyone is excited about it, plastics are pretty much everywhere. But what problems are they causing and is there anything we can do to solve those problems?

Plastic is quickly becoming a problem and we're eager to point fingers, but honestly, the reason there's so much plastic everywhere isn't just because of human negligence.

In this video Paul Andersen explains the basics of solid waste including trends over time, basic composition, and disposal. A brief description of the three R's (reuse, reduce, and recycle) is included as ways to minimize waste. ...
