Biodiversity's Last Stand: Innovative Solutions for Species Preservation
Let's turn the high seas into the world's largest nature reserve by Enric Sala

Let's turn the high seas into the world's largest nature reserve

by Enric Sala

What if we could save the fishing industry and protect the ocean at the same time? Marine ecologist Enric Sala shares his bold plan to safeguard the high seas -- some of the last wild places on earth, which fall outside the jurisdiction of any single country -- by creating a giant marine reserve that covers a third of the ocean.

Summary

In his TED talk, Enric Sala advocates for transforming the high seas—international waters covering nearly half of Earth's surface—into the world's largest nature reserve, directly addressing the trending topic of biodiversity preservation by proposing an innovative, large-scale solution to protect marine species from overfishing, pollution, and climate change, ensuring the survival of ocean ecosystems amid global biodiversity decline.

"The high seas are the last wild places on Earth, and we need to protect them before it's too late."

Discuss: What challenges might arise in establishing international agreements to protect the high seas, and how could they be overcome to aid species preservation?

Revolutionizing Waste: From Plastic Pollution to Circular Economies
We can recycle plastic by Mike Biddle

We can recycle plastic

by Mike Biddle

Less than 10% of plastic trash is recycled -- compared to almost 90% of metals -- because of the massively complicated problem of finding and sorting the different kinds. Mike Biddle has developed a cheap and incredibly energy efficient plant that can, and does, recycle any kind of plastic.

Summary

Mike Biddle's TED talk 'We can recycle plastic' highlights innovative recycling technologies that transform plastic waste into valuable materials, directly addressing the trending topic of shifting from plastic pollution to circular economies by closing the loop on resource use.

"Plastics are too valuable to waste."

Discuss: What steps can governments and businesses take to scale up plastic recycling and build truly circular economies?
