00:00So
00:30Oh, my heart, my heart, my heart, my heart, my heart.
01:00Ah, my heart, my heart, my heart.
01:28In 1815, a mysterious veil of dust began to spread over the earth.
01:36The culprit was a remote East Asian volcano, Mount Tambora.
01:45It was the largest eruption in modern history, spewing out 80 cubic kilometers of debris and taking up to 100,000 lives.
01:58But even this was just a fraction of what the earth is capable of.
02:04Supervolcanoes, like the ancient eruption of Mount Toba in Indonesia, can unleash 50 times the power and 30 times the amount of debris.
02:22An eruption of this scale today would be catastrophic.
02:25Potentially claiming up to 1 billion lives.
02:36There are about 20 active supervolcanoes on earth today.
02:40Sleeping beasts that present an even greater threat than asteroid strikes.
02:45Instead of waiting for them to explode, what if we could steal their energy and use it for ourselves?
02:54One NASA engineer has a proposal for exactly that.
03:02The idea is to drill a series of boreholes several kilometers deep around the outside of the magma chamber.
03:18Cold water would then be injected down into the rock, become superheated, then get pumped back to the surface to carry the heat away.
03:25Gradually cooling the magma.
03:26The location of the boreholes will be critical.
03:27The location of the boreholes will be critical.
03:28Drilling too close to the chamber itself would risk triggering an accidental eruption.
03:30But if done right, the superheated water removed from below is the surface of the magma.
03:37The location of the boreholes will be critical.
03:39Drilling too close to the chamber itself would risk triggering an accidental eruption.
03:45But if done right, the superheated water removed from below would provide a continuous source of renewable energy.
04:08And over tens of thousands of years, the energy removed may eventually be enough to cool the chamber completely.
04:15To fully protect civilization, we will have to neutralize not just every existing supervolcano, but all future ones.
04:36Magma plumes from Earth's mantle are continually bubbling to the surface.
04:45These plumes will continue to trigger supervolcanic eruptions as often as every 50,000 years.
04:55Learning to harness these forces could mean the difference between catastrophic collapse and the long-term survival of humanity.
05:08But it's not just supervolcanoes we will have to manage.
05:23From the lithosphere to the atmosphere, each of Earth's layers are prone to shocks that can threaten civilization and life itself.
05:35Our job is to protect and manage these layers with the power of technology.
05:42To build a safer, more livable planet where life and humans can thrive together for millions of years.
05:52And creating a safer planet starts with creating a safer climate.
06:01In 1991, the eruption of Mount Pinatubo ejected 20 million tons of sulfur dioxide into the stratosphere.
06:17Reflecting sunlight around the world and causing global temperatures to fall up to half a degree Celsius for nearly two years.
06:32The cooler temperatures even slowed the pace of sea level rise for the next decade.
06:39With global temperatures and climate catastrophes on the rise, this event inspired a bold idea.
06:47Artificial volcanic eruptions.
06:53Like putting sunscreen on the Earth, spraying sulfur dioxide high in the stratosphere would reflect sunlight and temporarily cool the planet.
07:06A single ounce of sulfur dioxide in the stratosphere can offset the warming effects of several tons of carbon dioxide for a year.
07:21Dusting the sky would have an immediate effect.
07:26Buying us time to decarbonize the global economy.
07:31But there's a catch.
07:36The exact effects may be unpredictable and uneven.
07:43Weather patterns could become erratic and threaten food supplies.
07:49With so much at stake, the fight for control over Earth's climate could even escalate into armed conflict.
07:57A team at MIT has developed a concept for a giant solar shield out in space.
08:24Thousands of kilometers across.
08:27Placed where the gravitational pull from the Sun and Earth balance out, it could reduce sunlight by 1.8%.
08:39Just enough to bring temperatures down to pre-industrial levels.
08:43The shield would be made of silicon bubbles, inflating out in space to ease their transport.
08:58And deflating if the solution needed to be reversed.
09:02To block enough sun, this solar shield would have to be absolutely massive.
09:14About the size of Brazil.
09:17Others have proposed systems of space mirrors to precisely redirect sunlight.
09:29Which could be used to increase solar radiation if temperatures drop too low in the future.
09:35This surface should be served Department of temperatureime mint July 2.
09:47This rain would be made influence by system of energy giant speed.
09:52Large-scale ecosystem engineering can go a long way in securing the stability of Earth's
10:17systems. In 2007, the United Nations launched the Great Green Wall Initiative, a huge effort
10:30to plant a 5,000-mile belt of trees across the entire African continent.
10:47This vast new forest will not only suck up a quarter billion tons of carbon, but also
10:54combat desertification, increase food security, and create millions of jobs.
11:09Managing our planet effectively will require forging deep alliances with the biosphere.
11:17That includes preservation of natural carbon sinks like the Amazon rainforest, which are
11:23a critical ecological counterweight to human activity.
11:32But in some cases, that may also mean bioengineering new forms of life itself.
11:46By tweaking the machinery of photosynthesis, scientists have recently created plants that
11:51grow up to 40% larger than their natural counterparts, hinting at a future of radically enriched crops
11:59and plant life.
12:04They have also begun to engineer algae that convert sunlight into clean-burning hydrogen fuel.
12:13And microbes that have been reprogrammed to generate electricity from mud and wastewater.
12:24But most dramatically, we are now on the path to creating a hybrid woolly mammoth, by tweaking
12:31the genes of Asian elephants.
12:42These creatures could be reintroduced to the Arctic, where they would help keep the permafrost
12:47frozen and prevent billions of tons of CO2 from leaking into the air.
13:04Genetic engineering could become our most potent tool for managing the planet.
13:10maintaining ecological balance and making the biosphere more diverse and resilient.
13:25The wonders of the future may not be built with concrete or circuits, but with cells.
13:35acho.
13:45ancient
13:49These are mechanical trees.
14:08They mimic the real thing by soaking up carbon onto special plates that act like leaves.
14:14Once captured, the carbon can be buried or recycled, and the cycle repeats.
14:28A single one of these machines can sequester as much carbon as a thousand living trees.
14:38Vast forests of artificial trees could be deployed in inhospitable regions.
14:46And with 100 million of them, we could offset our entire carbon emissions.
14:52The number of them, it might be more rồi to see if a problem is created in the same way.
15:02The number of them cannot be affected by thetós.
15:10The number of them, the number of them, the number of them, are stilltroopers.
15:16Excess carbon dioxide in the oceans is weakening food chains by causing the water to become
15:31more acidic.
15:35Pulverizing a part of barren seabed would allow rock particles to soak up the excess
15:40CO2 and restore balance to the waters.
15:47A single nuclear bomb placed five kilometers beneath the seabed could shatter enough rock
15:53to sequester 30 years of carbon emissions.
16:10The bomb would have to be massive, potentially over a thousand times more powerful than Zarabamba,
16:23the largest nuclear bomb ever dropped.
16:30But the deep sea water pressure would contain the blast and minimize fallout.
16:42The best location could be the remote Kerguelen Plateau, where the sea floor is mostly barren
16:49and rich in basalt rock.
16:59This is geoengineering at its most extreme and most dangerous.
17:08But preserving the oceans and millions of human lives makes even the most extreme ideas worth
17:14considering.
17:24For a safer way to manage the seas, we don't have to go far from shore.
17:33Artificial reefs built from sunken ships and man-made materials can become bustling marine
17:38cities.
17:40With some studies showing fish abundance increasing up to 20 times compared to bare seabed.
17:54Widespread artificial reefs could boost the ocean's natural carbon drawdown by offering habitats
18:00for trillions of corals, shellfish, and seaweeds that capture carbon during their growth.
18:14On a massive scale, these reefs could offer powerful natural defenses, reducing erosion and storm
18:21surges by absorbing wave energy.
18:26But managing our planet's hydrosphere is about more than protecting our oceans.
18:43It means preserving the glaciers and ice sheets that cool the world and hold back rising seas.
18:50This is the Thwaites Glacier in Antarctica, a massive ice sheet that spans 75 miles.
19:05Rising ocean temperatures are causing warm oceanic currents to wind their way underneath the glacier,
19:12causing it to crack and destabilize.
19:15If it collapses into the sea, it could trigger up to 10 feet of sea level rise, flooding coastal
19:26cities around the world.
19:31To avert disaster, a geoengineer at the University of Lapland has a bold plan.
19:42The idea is to construct a massive 100-kilometer-long underwater curtain around the glacier, designed
19:51to block warm ocean currents from reaching the underside of the ice.
20:01This vast undersea barrier would be engineered to withstand collisions with icebergs and could
20:07be removable if problems arise.
20:20At the opposite pole of the planet, ambitious proposals are being made to stop the loss of Arctic sea ice.
20:33Vast fleets of wind-powered pumps could draw seawater to the surface during the winter and spray it over the Arctic surface,
20:41where it would rapidly freeze in the frigid air.
20:48An American architect has recently designed a polar umbrella, which would float in Arctic seas, using solar power to harvest seawater and create new ice.
21:00Deployed in the fastest melting regions, these umbrellas would cast a cooling shade that would lower surface temperatures
21:18and rejuvenate the Arctic ice.
21:31But most of these grand solutions have a common problem.
21:36They each require enormous amounts of resources and energy.
21:44Where do we get the power and materials?
21:47And how will the insatiable demand for energy shape Earth's future?
22:03For the last two centuries, our energy use has been growing exponentially, surging over 7,000% and fueling a 100-fold increase in global economic output.
22:18Continuing this level of growth will eventually require generating hundreds of trillions of additional watt-hours every single day.
22:31Thanks to revolutions and solar power efficiency, covering just 0.3% of the Earth's surface and solar panels would be enough to power all of civilization.
22:45And the frontier of our solar-powered future will be one of the least livable regions of the planet.
22:53The deserts.
23:00Deserts provide ideal conditions for solar power with their vast, flat landscapes, abundant silicon, and constant sunlight.
23:16There are now proposals for massive-scale solar farms in the Sahara, capable of generating four times our current global energy usage.
23:23But covering over 20% of this desert could have dramatic side effects.
23:39The increased heat absorbed by the dark solar panels could disrupt global weather patterns and cause a spike in temperatures, especially at the poles.
23:52No matter how or where we get our energy, producing too much on planet will eventually be deadly.
24:03If our consumption grows at just 2% per year, we will use up all the energy available to Earth in as little as a few hundred years.
24:17But the real problem is that the waste heat from energy production at this scale would heat the Earth by over 20 degrees Celsius, which would make large parts of the planet uninhabitable.
24:33This will be the defining challenge of the coming millennia.
24:41How do we balance continuous energy growth with a safe, stable planet?
24:48By placing large-scale solar power arrays in space, we could capture uninterrupted sunlight nearly 24 hours a day,
25:15then beam the power down as lasers or radio waves.
25:26Orbital power systems would shed their excess heat into the cold expanse of space, instead of heating up our atmosphere.
25:34China is now planning a 1-kilometer-wide solar array with the long-term goal of beaming gigawatt levels of clean electricity down from orbit.
25:49And a team from Oxford is planning an even bigger station, 1.7 kilometers across, called Cassiopeia, designed to be built in orbit.
26:05But collecting the power in space and beaming it down still has its own waste heat problems, as energy is still being added to the Earth's system.
26:24The solution is to move our power-hungry industries entirely into space.
26:29This way, the energy can be collected, spent, and radiated completely outside of Earth's fragile system.
26:49And to get all this material into space efficiently, we need something incredibly audacious.
27:07Like a highway to the skies, a space elevator would open safe and easy passage to the next technological frontier.
27:33Enabling the build-out of next-generation space infrastructure.
27:36Enabling the build-out of next-generation space infrastructure.
28:03To build it, a cable over 36,000 kilometers long would be lowered from a counterweight out in space.
28:20Then anchored to a port station on the equator.
28:23A space station could then be positioned at geostationary orbit.
28:30At the point where the gravitational and centrifugal forces balance out.
28:36Laser or nuclear-powered rail cars would ascend the cable, carrying multiple tons of cargo at a time.
28:49Which could drive launch costs down to under $100 per kilogram.
28:5550 times cheaper than today.
29:05This could accelerate the mass production of solar power arrays, orbital data centers, research stations, and spaceports.
29:14Laying the foundation for a new orbital frontier.
29:35But building this beanstalk to the heavens would be a daunting engineering prospect.
29:41Requiring tether materials far stronger than anything that exists today.
29:51And moving human industry into space comes with its own major risks.
29:57Especially space debris.
30:02Tiny pieces of scrap metal as small as a fleck of paint can tear through satellites and infrastructure.
30:09Creating even more debris.
30:12Creating even more debris.
30:14And causing a chain reaction of destruction known as the Kessler Syndrome.
30:22To solve this, AI-guided laser systems could rapidly identify and deflect small debris.
30:29While larger pieces could be safely captured and deorbited.
30:39If we can neutralize these risks, then a space elevator could be just the beginning of an even greater vision of our planet's future.
30:54An even greater vision of our planet's future.
30:56This is the crown jewel of space infrastructure.
31:19The orbital ring.
31:23The orbital ring.
31:26This superstructure could become the backbone of our future civilization.
31:30A hub for everything from energy and transportation to climate management and tourism.
31:33In its basic form, a simple ring of wire would orbit the Earth around 200 kilometers up.
31:50With a stationary platform magnetically levitated above the spinning ring.
31:54It could be built as a free-floating structure or be tethered to the Earth at multiple points.
32:07Skyhooks and even hanging skyscrapers could dangle beneath the ring.
32:25Serving as launch points, research hubs or cities in the sky.
32:30Rotating the inner side independently would generate gravity through centrifugal force.
32:47Making the area habitable and offering spectacular views.
32:51While no current technology can simulate gravity on the outer edge.
33:10It could still serve as a zone for microgravity industries and research habitats.
33:15An intricate network of rings could be built at different inclinations.
33:28Offering rapid point-to-point travel almost anywhere on the planet.
33:32These layers could extend far outwards, even potentially networking with the Moon.
33:50But the sheer size of orbital rings would pose their own dangers.
33:55A shadow the width of the ring itself would sweep over the Earth each day.
34:14For narrow rings, this would have little impact on ecosystems below.
34:19But wider rings, stretching over 1,500 kilometers, could cause major disruptions to the climate.
34:32Blocking out the sun for an hour or more daily.
34:44Building one would be a towering engineering feat.
34:46As the ring would require tens of billions of tons of raw materials and constant active computer control to prevent collapse.
34:59To avoid impacting the Earth, the resources could be mined from asteroids.
35:05This may all seem like a far-off dream.
35:26But there are already proposals for prototype orbital rings that cost as little as $9 billion.
35:35People and heavy cargo could be transported along the ring networks,
35:52People and heavy cargo could be transported along the ring networks
36:04to anywhere on Earth in only a few hours.
36:12Vast orbital cities and arable land could circle the planet
36:16and serve as new human frontiers.
36:22And with energy and heavy industry woven into the ring,
36:30we could scale our growth without disturbing the planet,
36:34preserving Earth as a sanctuary for life.
