or impending children of your own. The Tropics are just less productive agriculturally than the temperate zones because of thinner, less fertile soils and more soil pests,
Weaver ants for example I'll give you a couple of examples now the V veins are called Weaver Angela finden in the old world tropics because they built a beautiful nest the leaf tent nests in a remarkable cooperative fashion do you see the pictures well down there it
They're basically ocean deserts. They're in the tropics , the water is clear, and there's very little nutrient in the water. Coral reefs have had to be really, really efficient to be able to grow there.
I was talking to him about what made the fish so valuable. live in the tropics .
And imagine that you're a sailor, now, on one of these ships and you're spending nine months on a boat on the way to Asia going through the tropics . It's very hot. It's hard to get fresh water so you bring beer and wine along and hops have not yet been invented.
Public health. There are going to be mosquitoes that carry dengue and malaria. They used to be confined to the tropics . They'll be flying in Scandinavia and even as far north as the Arctic Circle in the next few decades.
For us, we found that the roast goes so fast, it's really hard to actually consistently say, that's the color, whatever we want from an actual numbers And it grows in the tropics at a certain elevation range, and has these requirements for temperature and rain.
All they need is some clear water that's warm and that's shallow, and they're going to flourish. Every place in the world in the tropics where there's shallow water that's clear, we get coral reef formations. In addition to that, corals really like it when there is some grazing going on in the reef.
So arowana-- I should also just back up for a second and explain that it's a family of fish. So there's seven species across the tropics of the globe. And the really expensive one is the Asian arowana.
Economic strategies. Suicide actually spreads through these things, so when a celebrity commits suicide, people will copy method. But when you go into the tropics , there's lots and lots of spices.
Everywhere is impacted by human activities. And it was from Antarctica to the tropics in all these kind of different sort of conditions.
or impending children of your own. more disease problems in the Tropics .
of permaculture, of just understanding the world that we're living in, and so many different climates, because Indigenous peoples in North America were living from the Arctic down to the tropics . There's so much amazing, amazing stuff to think about there.
It's quite effective at reducing extreme precipitation. And one very important version of that in the tropics is cyclones or hurricanes. And it turns out that when you cool the world with this solar geo, you have a stronger effect in dampening
They want the temperature to be between here and here, and not above it and not below it. And the reason for that is that living in the tropics , the weather is actually very predictable. From one year to the next, from one season to the next, it's a very predictable environment.
I was talking to him about what made the fish so valuable. Most Freshwater fish-- the vast majority live in the tropics .
Economic strategies. Suicide actually spreads through these things, so when a celebrity commits suicide, people will copy method. So if you've spent any time in the tropics living off reef fish, this is some you've got to watch out.
And then I think actually just the last thing I did manage to get into the book, the last story was about how cone snails-- these are poisonous sea snails that live in the tropics . They are notorious for having incredibly diverse and complex toxins that they use to hunt all sorts of animals, including
And without minimizing the problems that the polar bears are facing, what I write about it in the book, actually, is that it's actually likely that climate change is going to have an even more profound effect in the tropics . And there are a couple reasons for this, one of which is just that the tropics are where most things actually live.
who come with very, very different training, very, very different way of thinking about it they've started to be able to find new kinds, different place in the world that insects have in the tropics than in where we live in the temperate zone and whether the relationships
And we are quickly transitioning from using coal to make photovoltaic panels to using renewables. Hydroelectricity varies dramatically because if you build a hydro dam in the tropics , you trap a lot of organic material in it, which decays and produces methane, which is a powerful greenhouse gas.
You've got body proportions that looked very much like people living in the tropics today.
And they, and in the tropics they, they congregate by the millions.
And there's this slow circulation in the stratosphere where things tend to rise in the equator and sink near the poles. And the boundary between the stratosphere and the troposphere is at about 17 or so kilometers in the tropics , and then much lower in the extratropics. So when you fly between North America and Europe, especially in the winter, you're well into the stratosphere, but not when you fly across the equatorial
is forest destruction. And most of that is taking place in the tropics .
So you don't just get big coral heads like this, corals also build entire islands. This is an atoll, which is a special kind of island found in the tropics . It is special because that island is built entirely out of coral.
And one of the explanations I've heard for this is that the Appalachian Mountains were suddenly getting created in the tropics , which would have accelerated
We were beginning to learn that the Gulf Stream was a powerful current that brought a lot of heat from the tropics north through the Atlantic Ocean
to have an even more profound effect in the tropics . And there are a couple reasons for this, one of which is just that the tropics are where most things actually live. So in this slide, you're looking down from about 12,000 feet.
If you haven't seen it, one of these times when you're in the tropics -- and usually you've got to go out late at night-- it's very
the plastic and absorbs the solar energy and what happened here was this stuff buckle that's in the tropics it's got
who come with very, very different training, very, very different way of thinking about it they've started to be able to find new kinds, find here and, um, in the tropics in general. Well, one thing -- one thing that I've been thinking about recently in that respect -- is that I'm not sure whether
a Star Wars vision of raindrops and galaxies and moths flying in my eye. People don't realize you can get hypothermia in the tropics , but as you're going at night, even if it's
Siberia, pretty rough. No, you'd look for the tropics . You'd go you'd go down close to the equator.
A lot of what's healthy in our marketplace today comes either from South and Central America in the winter months, or it comes from the tropics year-round.
So depending on where you are, you may find those same corals in very deep water in the tropics and at the depth that you can snorkel in Alaska.
This is a mosquito that has dramatically expanded its range as we have urbanized, especially in the tropics .
This is clearly something that is an adaptation that arose in mammoths as the tropically-adapted ancestor of these two species moved out of the tropics
If you take that amount of touching and then say, all people that happen to go on a hotel vacation in the tropics ,
who come with very, very different training, very, very different way of thinking about it they've started to be able to find new kinds, Yeah. Thank you. I know you spent quite a bit of time in the tropics when you were
have seen ice reduced on the globe. The main places for ice today are on the tops of the high mountains in the tropics and mid-latitudes, and in the big icecaps in Antarctica and Greenland,
