- Megafires, or fires that burn more than 100,000 acres, are becoming more frequent worldwide, wreaking havoc on landscapes and communities -- and fire experts say the problem is only going to get worse. George T. Whitesides is focused on fighting these devastating natural disasters through innovative technologies and intentional changes to how we build communities. He presents three emerging solutions to this blazing dilemma, calling for us to redefine our relationship with fire in order to build a more resilient and sustainable future.

Do the corporations have any responsibility when the strip mine a forest and leave everything except the stripped tree behind?
@@austindenotter19 I can show you photos of so-called reclamation. You won't see the strip mining of forests along the main highways. What you don't see you don't know.
OMG we don't need bots and robots, we need goats clearing brush and arborist doing controlled burns. It already works, why is everything a bot or robot, JFC!
money
A-"greed".
It's about scale, speed and efficiency. There is much much work thats needs to be done to maintain and evolve the world you live in, than it was few hundreds years ago. We take care of the electrical grid, internet, cars, tourism, big houses, technologies people use every day. It needs care as well and there is not enough people, not enough specialized people and it takes a lot of time and effort to train all the people.
There were times when there was no plants on this world, no mushrooms, no mammals, no humans, no villages, no cities, no computers, no robots. What makes you think you know better than nature what kinds of structures are needed for the stage of life this planet is in?
Speaking of controlled burns and technological innovation, it does seem like a shame to release so much carbon to avoid larger scale fires. Are there or could there become any scalable firebreak creation technologies that pyrolyze into biochar or organize and bury felled trees to both stop megafire and capture a majority of stored tree biomass carbon?
@@Boro2p LOL you asked how I know better than nature, but think somehow bots and robots are more efficient than natural methods, LOLL
Good looking out.
This happens effortlessly in healthy ecosystems. Return the animals that naturally exit in nature and connect the ecosystems with wildlife corridors. It's already shown to restore environments and reduce the incidence of wildfires and floods. My masters is in climate change and sustainability. Arborists and goats (which don't need to be trained to eat underbrush, they just need to pen off the area where goats work) are only needed in densely populated areas. It's not expensive at all, it saves a crap-ton of money - actually. And the reason we don't have more arborists is because the have gutted the EPA. Best job you can hope for is one in a national park where you get to live there but still have to pay rent. I almost became an arborist. But those jobs are funded through taxes, and I can already tell a conversation about taxes with you is useless. One person making billions on bots rather than 5 people making a living wage is not sustainable, and that's the future you are proposing.
I literally dedicated my life to this, but cool bro I'm sure you're an internet expert on everything.
You can't contain fires at the massive speeds at which they travel. If it's windy, fire flies, every leaf and spark will fly with the wind and the higher the fire, the faster it flies.
We need all the help we can get! Canada, Russia, (supposed to be snow, and wet) and the Amazon Rain forests have been burn like crazy for a long time! Why does nobody talk about this?
Thanks ❤
How far do you expect a chinook to fly when a fire starts? How many do you think you need? A thousand for California? How long will it take to get to a fire? How much to they cost, fifty million dollars each?
🌳=🌧=💧All trees make it rain except conifers and eucalyptus ... Deciduous trees strengthen the water cycle, while conifers and eucalyptus create megafires.🌲=🔥
prescribed burns only make drying out of forests worse.the bacteria in soil that trees use to network is destroyed ultimately creating weaker less quality lumber.while also creating monocultured treed forest
In NYS, we have Forest Management. Our Fire Departments do controlled burns. We had a large fire during the pandemic having no rain for months giving NYC a drought as well. I contribute that fire to the pandemic bc we did not have the manpower and climate changes. Our fire department for the most part consists of volunteers.
Thank you for this presentation. Maybe it will wake up the climate change non-believers.
"ultimately, we need to become the crew of spaceship earth, so let's get to work, let's learn from fire, and let's build a resilient sustainable future"
DRY ICE BOMBS!
This is just called Forest Management in Michigan.
Forest management helps in built-up areas, but it doesn't do miracles. And you try and do forest management in vast wild and uninhabited areas of Canada and Russia that are larger than the entire USA.
Reductionism is derogatory and not an effective solution.
@@SylvainDuford those vast areas in canada that are on fire "to that level' are result of global warming. Those fires that are in California are part of the ecosystem historically then people build their summer homes on unmanaged forest land and some smart guy probably with a summer home vested in that area makes a TED talk video.
good
Absolutely NO BURNS.... That's been done in Australia for hundreds of years and it doesn't work. We need animals to feed on that stuff. To eat what you plan on hurning. Burning will only destroy the land, we need to feed it well.
You're talking about burning it all down and now you're talking about building it up again? Which is it? You can't have both.
As climate change gets worse these (very concerning) surprises seem to be coming along more and more.
Maybe just stop spraying chems in the air for a decade for example.. and see if the fires are as severe and reacquiring as often?? Don’t cure the symptoms , look at the cause.
日本のみんなこれを見て受験勉強頑張ろう！夏を制そう
natives never stopped fires from approaching cities, that is non-sense, and gets repeated constantly
Two individuals from George Mason University developed a subsonic fire extinguisher. Combine it with a team of air moving drones and you can solve your problem.
AVA aircraft vigilance & attack. Dedicated SEAT's. Public aerial firemen. Chinook's are so expensive to operate that fire managers hesitate to deploy them. SEAT's flight hour is so inexpensive that these should be deployed to hunt for fires. Aircraft vigilance and INSTANT attack. Has been done. Has been proven. It hasn't catched on because of going against business's interest, sadly.
He said (discovery)😂😂😂😂...

Wow do something to bethanny garcia

Why not just allow lumber companies to cut a grid into high risk forested areas. This would create natural barriers to slow the spread of mega fires, while helping to lower home building costs. Harvesting that lumber rather than burning it down would create a new industry, create tons of jobs, and offset (if not eliminate) the costs of the fire prevention measures. Like allowing hunters to buy tags for over populated areas.
Correct in theory, but it’s not about allowing the lumber companies to cut grids, it’s about making them.
They clear cut huge swaths of land because it’s efficient.
We know that the forest in cally burn and we keep building in them. Also many of the fires are man made. I wish I could spare sympathy but I can’t…
This is not a job for government, rather it is a job, obviously in my opinion, for the insurance companies.
Bureaucrats come and go and carry little true responsibility.
Insurance companies have many obligations, to the home owner and especially to stock holders.
It is in their interest to take on the problem more seriously.
Very good point
Insurance companies are in it for the money.
It's easier for them to just hike the premiums for those in danger or refuse to insure them at all.
They aren't going to spend money making an area safe for people who might not even have insurance, or are insured with a different company.
They got our money…. I mean they got the money!
@@dondoodat Insurance companies do not usually engage in private regulation like what I propose because, like most of us, we think its all covered well by the government.
Well, it's not. The public sector has failed here, and it is time to have insurance companies step up and do their job.
Which they will have to do if they want to make money insuring people and avoid having to put it out.
And if the people in these areas cannot get insurance, they should not live there...and then sup at the taxpayers table.
The court system is right there to adjudicate disputes that will invariably arise.
Perfect? NO! Better? YES!
@@MrJoeybabe25
No, it's totally impractical.
Are you going to force people to take out insurance, or are you going to get the government to repossess their homes if they refuse to ?
If ten houses in a local area have ten different insurers, which one are you going to force to do the work and under what penalty if they don't ?
If there is still a fire afterwards, will the insurance company be prosecuted for not doing a good enough job ?
What you're trying to do is force a company to do something that isn't in their interests, how do you intend to force them to do it ?
It would never work, sorry.
You might as well make security companies responsible for preventing people from becoming criminals.
WHAT is CHUZPA?
When a pyromaniac not only tries to charge u 10 grant for his DEW expences (gasoline, flamethrower, helpers etc)... BUT additionaly sues u for 10 Million bucks for a self inflicted sore thumb suffered in the act of >burning down ur house.
The best way to manage fires is to manage the landscape before the fire ever happens. This means logging.
o lord help us.ur mentality has poisoned us for too long
Let Earth manage as it has done since 4.5 billion years
You lost me the minute you started describing fire as a moral problem rather than as a environmental one.
One thing that might help is for you all to stop blaming arson on the climate.
Better not link it to climate change.
Jail the arsonists that are starting many of these fires for one.
It is unknown many times how fires start. How can one find the arsonist in a forest of thousands of acres? Lightning starts many of them when it’s very dry. I live in a mountainous area near six digit acreage of forest. We have a preserve and a state park. Controlled burns are performed regularly. During COVID it had stopped which I believe is part of the problem we’re having now.
Tell people you don't believe in climate change without telling people you don't believe in climate change.
@@austindenotter19
You claiming that environmentalists are destroying the environment to prove a point ?
Do you have any evidence to substantiate such a claim ?
@@dondoodat Climate change isn't starting the fires. Unless that's the name of an arsonist.
What about “stop burning fossile fuels”?

if we CUT DOWN all the trees in hazardous areas the fire problem would have no place...
Do people still watch TED Talks? I thought they had become Woke Struggle Sessions.
Well I got some real bad news for you. It's way way way too late... The window of opportunity to manage our forests and set controlled fires is no longer. There is no time in the season that that is safe to do anymore. Bye-bye. Don't believe me. Ask experts in fire behaviour that have been studying this for a long time.. too late...
