Plastic was long considered to be a revolutionary material. But, what has it turned into now? A trash – and millions of tons of it end up in the ocean every year. Of course there are plenty of attempts to thwart this growing problem, but this approach by the Ocean Cleanup seems to be the most effective. Here’s how it works.
Prochlorococcus is the most abundant photosynthetic species on the planet that has existed for millions of years. The marine microbe was not discovered until the mid-1980s. In this TED Talk, Oceanographer Penny Chisholm explains how this amazing little being's ancient genetic code can help us in reducing our dependence on fossil fuels.
Geologists believe Earth has an eighth continent called Zealandia, which makes up 4.9 million square kilometer region of the southwest Pacific Ocean. Today, 94 percent of this gigantic landmass is underwater. Here’s what it has got to teach us about geology.
How we can save the fishing industry and protect the ocean at the same time? The answer: create a marine reserve (a huge one). In this TED Talk, marine ecologist Enric Sala shares his bold strategy to safeguard the high seas by making a giant marine reserve that covers two-thirds of the world's ocean. Sala believes protecting the high seas will help us restore the ecological, economic and social benefits of the ocean.
67 percent of Southern California beaches will be gone by 2100. And that's all because of sand. Yes, we are using up sand faster than the planet can make it.
One day, we could be using the cold darkness of outer space to cool our buildings. In this TED Talk, physicist Aaswath Raman talks about the technology he's developing to harness "night-sky cooling" .
Climate change is real, and the earth is getting warmer. While you might be thinking limiting carbon dioxide emissions is the only way to help combat that, scientists are looking for plan B.
Earthquakes occur when two pieces of the Earth’s crust called tectonic plates collide or grind against each other. When this happens, an insane amount of energy from inside the Earth suddenly bursts out in all directions causing the Earth to crack and shake everything on top. Well, we know earthquakes are awful, but how much damage can they do?
If the earth were twice as big, the earth would have eight times as much mass and gravity would be twice as strong. Your weight would also be doubled, and it would be much harder for you to walk because you'd feel like you were giving another version of yourself a piggyback ride all day, every day. And what else? Trees would collapse. Gravity determines how tall a tree can grow - so any new trees that grow in their place wouldn't grow as tall.
The damage mankind has done to the earth’s ecosystem by dumping plastic wastes alone is beyond horrible. But thanks to scientists who stood up to fight it alongside their inventions. […]
Rainforests cover six percent of the planet, and they are home extraordinary and wonderful creatures such as jaguars, sloths and toucans. You know about those, but what about those horrible […]
The average demand for oil and liquid fuels per day worldwide is 96 million barrels – that’s more than 35 billion barrels a year. With the demands on a steady […]
