They're essentially crowdfunding for nature.
3
Every month, their community funds a new nature protection mission, and they document it through videos on YouTube.
4
But more on that later.
5
There's not a single person in the world that knows how to make this toaster.
6
I know that might seem impossible, but it's true.
7
Let me explain.
8
In 2011, British designer and writer Thomas Thwaites tried to build a toaster from scratch.
9
Nothing crazy, just a simple electric toaster, equivalent to any cheap one you could find at a department store.
10
He figured, especially with his design experience, how hard could it be?
11
Turns out, for one person, it's impossible.
12
When he bought and opened a toaster to base his own on, Thwaites was immediately distraught.
13
Despite it being a cheap $6 toaster, there were 400 parts made of more than 100 different materials.
14
How was he possibly going to acquire or make all the materials and parts needed?
15
He had little to no idea where to obtain things like iron ore, plastic, copper, and rubber.
16
And so he began talking to professors and experts, reading up on the history and logistics of various kinds of material sourcing and manufacturing.
17
Over the following nine months, Deweyts found himself on an obscure journey across industries, the world, and history.
18
He got copper from an abandoned mine on the island of Anglesey in Wales, obtained iron ore from Clearwell Caves in England, and then tried to smelt it using a homemade furnace,
19
extracted mica off mountains in Scotland, and attempted to make plastic from potato starch in his backyard.
20
In the end, after nine months and thousands of dollars, Dwight's essentially had nothing in the form of a fully functioning toaster.
21
He couldn't figure out how to make rubber from scratch, so the wires had no insulation, and after five seconds of the toaster being plugged in and ran, the heating element melted itself.
22
Thwaites' entire experiment, which would come to be known as the Toaster Project, was inspired by a scene in Douglas Adams' novel series, The Hitchhiker's Guide to the Galaxy,
23
where a 20th century man finds himself stranded on a planet with technologically primitive people.
24
He assumes that with his experience with advanced technology, he'll be able to become a kind of emperor of the planet and transform its conditions.
25
Instead, he soon realizes, although he originally came from a world which had cars and computers and ballet, and Armagnac.
26
He didn't, by himself, know how any of it worked.
27
He couldn't do it.
28
Left to his own devices, he couldn't build a toaster.
29
He could just about make a sandwich, and that was it.
30
Without the rest of modern society, the intricate network of people, knowledge, and systems, each with their own essential node in the process of civilization and its products,
31
the man really couldn't do much of anything in the modern technological sense.
32
The Weitz project showed that this is also true for each of us on this planet right now.
33
Think about every object you use on a daily basis, from simple household items like forks,
34
bottles, and couches, to intricate devices like phones, computers, cars, and toasters.
35
Every single one of them have massive intricate lineages of conception, design, production, and distribution required for them to wind up in each of our hands and homes.
36
As individuals, not only understanding, but carrying out the complete process of production for any object or technology,
37
let alone all the objects we use, would be impossible.
38
With exception to simple, primitive tools, we would not accomplish much of anything on our own.
39
Consider that in the case of a simple toaster, the copper for the wiring might be mined in Chile, processed in China, and then sent elsewhere for assembly.
40
The nickel that makes up the heating element might be mined in Indonesia, and then sent to China to be refined.
41
The iron ore might be mined in Australia, which still needs to be smelted into iron, refined into steel, and then fabricated into the parts that make up the toaster's body and frame.
42
This goes for every part and material of the 400 plus parts that make up a simple toaster.
43
Hundreds, if not thousands, of individuals are essential to the process.
44
Miners, designers, engineers, chemists, manufacturers, business operators, deliverers, and so on.
45
Most of whom only know how to carry out their part of the process.
46
Almost everything you use
47
and touch on an average day is a kind of miracle forged out of the material of the earth
48
and the human mind.
49
Human engineering facilitated by vast networks of manufacturing, brought to you by carefully orchestrated distribution channels,
50
all of which originated from human thoughts and ideas.
51
In the words of poet John Donne, No man is an island entire of itself.
52
Every man is a piece of the continent, a part of the main.
53
beginning of everything.
54
One thing that Thwaites discovered that is even more interesting
55
and potentially existential crisis inducing is that the smaller the scale you want to work on, the further back in time you have to go.
56
Every man-made object and technology is not only connected to the web of modern industry, but also to the web of human history.
57
The history of everything.
58
Every new idea, every new design, every new object and technology is built on the back of prior ideas,
59
designs, and technologies, all the way back to the first and simplest ideas and technologies.
60
Man learned to create fire hundreds of thousands of years ago, so that now we can toast slices of bread equally on both sides at the same time.
61
One does not exist without the other.
62
Nothing exists without everything that led to it.
63
But where did everything come from to begin with?
64
Where did it all start?
65
Humanity itself does not exist in a vacuum.
66
We are a species in the context of nature and evolution and the world.
67
And yet we are apparently alone in creating fire, forging swords, constructing buildings, flying planes,
68
in building computers and digital intelligence systems, and everything else.
69
But why is this the case?
70
Why and how did humanity separate so significantly from the apparent nature of everything else?
71
The answer is, in large part, found in one of the most unsuspecting and almost humorous places.
72
The thumb.
73
The opposable appendage sticking out the sides of each of our hands.
74
By appearance alone, the opposable thumb might seem to be a modest biological mutation, but this little appendage changed the world completely,
75
allowing for a whole new realm of existence.
76
All the networks of civilization that we experience today, every technology and man-made object, the state of the world, our endless yearn made tangible,
77
is in large part the product of this thing on our hands.
78
With it brought almost everything else.
79
The Thumb Brain In 2025, a study out of the University of Reading in the UK,
80
titled Human Dexterity and brains evolved hand in hand, explored the relationship between the size of opposable thumbs and the size of brains.
81
The researchers analyzed nearly 100 living and fossil primate species, including humans, chimpanzees, gorillas, orangutans,
82
macaques, and other ancient hominin species.
83
What they found surprised them.
84
Longer thumbs not only appear to have a correlation with larger brain sizes, but the part of the brain that is bigger relative to longer thumbs is the neocortex,
85
the part of the brain responsible for higher order functions like conscious thought, sensory perception, spatial reasoning, and complex language.
86
This suggests that these two things potentially grow together, the thumb and the neocortex.
87
On the face of it, this might seem kind of absurd.
88
How or why would the thumb have any direct relationship with consciousness, with language, and with the complexity of thought.
89
Though certainly bizarre, after examining it further, it makes a lot of sense.
90
Without thumbs in some form, we wouldn't be able to meaningfully create or engage in anything that requires gripping, grasping, holding, or pinching.
91
This includes early primitive tools like hammerstones, axes, sticks, and spears.
92
If humans never evolved thumbs, these tools would likely have never existed in the forms they did, and tools would have likely remained extremely simplistic.
93
Consider the tools of other species without opposable thumbs.
94
Crows bend and shape twigs, finches use cactus spines, otters use rocks, and elephants direct branches with their trunks.
95
All of which is extremely simplistic, imprecise, and limited.
96
This of course matters a lot.
97
If human tools remained equally imprecise and primitive, then early humans would have been less precise in what they could do and build with such tools.
98
And if humans were less precise and more simplistic in their interfacing with the world,
99
then the mental modeling required to engage with tools in the world would have also remained more simplistic and minimal.
100
A species doesn't need complex terms and conceptual modeling for a world that they poke and smash.
101
But for a world that comprises increasing intricacy and strategy, it does.
102
Complex tools seem to apply a kind of pressure on the brain to expand.
103
As the possibility and complexity of tools increase, so too must cognition.
104
And as cognition increases, so too can the complexity of tools.
105
What seems to be the result of a limited ability to grasp and grip isn't a slower development of tools, but it results in them never really getting off the ground floor.
106
Consciousness thus never really expands and civilization never begins.
107
But of course, we did evolve thumbs.
108
We learned to grasp, grip, pinch and create.
109
We created axes and hammer stones, then spears and bow and arrows, then plows and the written word, then cars and planes and computers.
110
Each of these creations expanded the possibilities and needs of the human species.
111
At each point, the complexity of our relationship with the world grew.
112
And at each point, so too did our cognitive abilities, creating a feedback loop where every cognitive enhancement has led to a greater ability to create more advanced tools
113
and technologies which continues to lead to cognitive enhancements, so on and so forth.
114
What have we done?
115
In the early 1890s, there were new campus buildings being constructed at Ohio State University.
116
As part of the new developments, a large central grass space was created that would come to be known as the Oval.
117
For years, there were no official walkways in the Oval, just an open field.
118
As students began walking across the grass to get to and from different buildings, however, they began choosing specific routes that were shortest or most convenient.
119
Soon, dirt trails began to appear on these routes as the students wore the grass down from frequent walking.
120
Then, even more students began to walk the same routes, now with the addition of a visual Trail.
121
These worn down trails are what are known as desire paths.
122
They appear all over the world in cities, campuses, and parks for similar reasons.
123
By the early 1900s at Ohio State University, the university based their placement of concrete sidewalks in the oval off these desire paths.
124
The outcome was a strange asymmetrical pattern of sidewalks sprawling across the grass field, each path meeting at certain centers and connection points,
125
altogether creating a a kind of webbing of apparent random connectivity forged by the continual patterns of human desire and goals.
126
We so often feel like we are choosing where we are going, what we are doing, and why.
127
But history is a desire path.
128
The world is a network of these apparently random connections forged by the patterns of human desire and goals,
129
through which we each walk every day and every moment.
130
The development of tools and technologies don't merely affect how we tangibly interact with the world, but also how we understand and think about it abstractly.
131
We each not only arrive with our thumbs, but we arrive with our particular cognitive models of the world, a particular size of the neocortex,
132
and an understanding of phenomena developed and facilitated by a state of technology and a corresponding state of culture.
133
Thumbs did not merely lead to spears, spoons, writing, toasters, and cell phones, but they They also, in some meaningful sense, led to the creation of religions,
134
of philosophies, of ideologies, of beliefs.
135
Where does everything go from here?
136
Before Thumbs, animals couldn't grasp or grip the world.
137
Thumbs evolved as a way to literally do this, to gain greater control over the world and its inherent chaos and uncertainty.
138
But ironically, through what Thumbs have allowed us to do and create and understand, we have We have mostly discovered how little control we can ever have over anything.
139
We have built an unfathomably complex civilization.
140
Cultures and industries, ideologies and religions and philosophies, math and science.
141
We have created fire and toasters and smartphones, all to have no control over or understanding of the very things and systems we built.
142
The modern world is a kind of self-propelling network of desires formed from the walking paths of the humans
143
and species before us.
144
Modern industry and culture move forward, producing new technologies and new ideas that appear in our hands and our homes and our minds.
145
And yet, we never really can see or understand the complete process of any of it, where it all comes from, how it's made, and why.
146
Ultimately, each of our existences are a network of contingencies that no one person or group ever had a say in,
147
ever started, or can ever fully understand or take control of.
148
Our beliefs and ideas are really not so dissimilar from a toaster, made of hundreds if not thousands of parts and materials sourced from all over the world and tracing deep into history.
149
What would we have been without thumbs?
150
What would the world have become?
151
Perhaps something entirely alien to us.
152
Or perhaps something incredibly basic and simple.
153
We'll never know.
154
But we can know that the world that we have created appears entirely alien to everything else in the cosmos.
155
A beautiful and terrifying array of technological and cognitive possibility.
156
Of desire and need.
157
Of good and bad.
158
Of intelligence and ignorance.
159
We don't know where we are going or why.
160
We don't know why the whole process started.
161
We don't know what our thumbs and minds will hold next.
162
But in any and every moment, we can know just how absurd and improbable holding anything is.
163
From the simplest to the grandest of moments and objects.
164
For a toaster to arrive on your counter.
165
For a pen to arrive in your drawer.
166
For shoes to arrive on your feet.
167
A phone in your pocket.
168
A concept in your mind.
169
and a thumb on your hand.
170
Through our thumbs and minds, we have changed the world completely.
171
This is no doubt equated to many miraculous things, but it is also equated to many devastating things.
172
We must use our thumbs and minds, our capabilities and power, as much as we do to create and innovate, to help preserve and protect this planet, to undo damage we've done,
173
and to help nature in ways that only we as humans can.
174
That's one of the reasons why I joined Planet Wild, and why I'm so thrilled to be partnering with them for this video.
175

184
One recent mission involved helping restore the world's largest tropical lake, Lake Victoria.
185
This lake supports around 45 million people and over 600 freshwater species.
186
Right next to it is a forest that helps support it, which has been severely degraded over recent years.
187
Planet Wild is helping reverse this by planting 80,000 trees
188
and funding the necessary tech to make sure the forest and surrounding ecosystem can thrive long term.
189
Perhaps one of the most impressive feats humanity has ever accomplished, of which Planet Wild is at the forefront, is bringing nature back to life.

Cos'è la tecnica dello Shadowing?
Shadowing è una tecnica di apprendimento delle lingue supportata da studi scientifici, originariamente sviluppata per la formazione dei traduttori professionisti e resa popolare dal poliglotta Dr. Alexander Arguelles. Il metodo è semplice ma potente: ascolti un audio in inglese di madrelingua e lo ripeti immediatamente ad alta voce — come un'ombra che segue il parlante con un ritardo di solo 1–2 secondi. A differenza dell'ascolto passivo o degli esercizi di grammatica, lo shadowing costringe il tuo cervello e i muscoli della bocca a elaborare e riprodurre simultaneamente i modelli di discorso reale. La ricerca dimostra che migliora significativamente la precisione della pronuncia, l'intonazione, il ritmo, il discorso connesso, la comprensione dell'ascolto e la fluidità del parlato — rendendolo uno dei metodi più efficaci per la preparazione alla prova di speaking dell'IELTS e per la comunicazione reale in inglese.
