TED Talk. Paul Greenberg: The four fish we are overeating

7.03.2024

“Grinding Nemo”

Overfishing is only half of the story, says Paul Greenberg in his talk. The other half is about the boom in fish farming and aquaculture, which – over the past few years – has started to exceed the amount of wild fish produced. In America and a great part of the Western World, shrimp is by far the most consumed seafood. 5, 10, 15 pounds of wild fish – deemed trash fish by the fishing industry – are killed to bring one pound of shrimp to the market. Filmmaker Mark Benjamin called the phenomenon “Grinding Nemo“: Shrimp dredgers vacuum up a huge amount of by-catch that is then minced and turned into shrimp feed. An „ecosystem literally eating itself and spitting out shrimp“. A recent study has found that dredging for shrimp represents one of the most carbon-intensive ways of fishing there is.

Electronic Waste: Intoxicating Agbogbloshie

24.12.2023

At breathtaking speed, our world is being inundated with ever more sophisticated electronic equipment. Devices hardly a year or two old, are replaced at increasing frequency, to be cashed in or be thoughtlessly dumped for the next much fancier gadget. Most “outdated” models are added to a recycling bubble already straining at the seams. Considering that resources are scarce and thus valuable, this rotation system is still unrivaled. Yet, have you ever wondered how – and above all – where, your discarded cell phone, laptop or PC may have ended up eventually? More than half of the electronic waste from, for e.g., the United States, is shipped to countries fairly ignorant of environmental issues – like for instance to China, India or Ghana in West Africa. A Boston-based company is shining a light for sensible recycling worth copying.

TED Talk. In Slow-mo or Time Lapse: Awesome Wonders of Nature

12.11.2023

A Treasure Trove for Science

Surely you have seen dragonflies hover. But did you know that they were also capable of flying backwards? Or even up-side down like a vintage double-decker during a daring air show? And that they could activate each one of their four wings separately – working at varying speed and propelling in different directions, all at the same time? Today it is possible to shoot images that are thousands of times faster than our own vision. Or slower. We can see how nature’s devices work – and imitate them. Helicopters or mechanical drones pretty much simulate the congenial dragonfly’s techniques. We live in a world of invisible beauty, too subtle to be perceptible to the human eye. Louie Schwartzberg shows breathtaking images during his fascinating TED talk.

Common Sense vs. Decadence

The 25 most expensive Dishes and Drinks compiled by Ignitespot

As is widely known, there are many sappy fruitcakes on the face of this earth, some even make it to the top of politics. But no, what we are talking about here is genuine food, albeit of a nature that again gives reason to doubt reason. Spending a fortune on a humble slice of Japanese Miyazaki Wagyu beef – the Kobe superlative – may still be somewhat comprehensible given the fact that body and soul of an Asian cow need to be pampered into beef so artfully marbled and tender that effort and price are warranted and the cow is a happy one until death do them part, bovine and farmer. If you are a good Miyazaki-Wagyu-beef producer you might even win the Japanese Culinary Olympics Beef Competition held in Nagasaki every five years. And so it happens that a slice of Lancashire Wagyu & Mushroom Pie served in England may cost you a handsome 1,781 US-$.

TED Talk. Elora Hardy: Magical houses, made of bamboo

3.04.2021

Imagine you were the fortunate citizen of a lush tropical island, say Bali, and financially privileged enough to afford an extraordinary home built according to your most daring desires. Ideally, renewable materials would be used almost exclusively so that your new residence became a sustainable and thus environmentally friendly affair. Bamboo is one of these resources – abundantly available locally, easily cultivated and growing back rapidly. It is light yet sturdy, albeit a little stubborn when it comes to delivering reliably straight rods: No two poles are alike and creative thinking is required on a permanent basis in order to come up with a feasible design. In Elora’s case, her enigmatically shaped edifices are the surprising result of these given twists and curves. Bamboo structures can now last a lifetime. Whereas formerly they used to get eaten away by insatiable termites and bugs, this building material receives treatment with a boron solution, a natural salt despised by hungry insects.
