Every year, humans change
10 million hectares of land,

and not for the better.

Right now, there are more than two billion
hectares of degraded land

around the world.

We need to fix this fast,
and technology can help.

Restoration is an enormous,
complex challenge.

It cannot be done
by simply planting trees.

We need to bring native,
complex ecosystems back to life,

and it requires deep ecological expertise.

Until now, we have been limited
to poor facsimiles,

like vast plantations
of a single kind of tree.

But drones change that
by allowing us to gather data

and plant the right mix of vegetation
quickly, at enormous scales.

And machine-learning analysis
enables us to plan the planting

and then monitor our restoration work.

For example, in Australia,

we’re using drone-based planting
and ecology-trained AI

to restore thousands of hectares
of land mined for coal.

Not just planting trees,

but bringing back biodiverse,
complex ecosystems.

On a larger scale,
native forests here in Australia

have been decimated
by catastrophic bushfires

and land-clearing for agriculture.

This means diminished food sources
and safe habitats for koalas.

A new project would allow us to accelerate

the restoration of thousands
of hectares of koala forests

over the next few years.

With these combined technologies,

we’re able to scale up restoration

from a small island
to an entire continent.

We can return forests to land
where a mine used to be,

or recreate ecosystems

like the one we’re hoping to restore
on Lord Howe Island,

birthplace of one of the world’s
largest insects.

This unique island
is plagued by imported species,

where we’re helping to eradicate
the undesirable plants

to allow endemic species to thrive.

It’s not just billions of trees.

It’s restoring nature
in all its complexity and beauty.

Thank you.

    Technology is awesome, but “ecology without class struggle is gardening”.
    Chico Mendes always on point.

      @walperstyle Ecologia é o estudo do meio ambiente e dos seres vivos que o habitam, é a ciência que lida com as relações desses indivíduos e sistemas. Esses indivíduos, por sua vez, estão sujeitos ao sistema no qual nós nos organizamos como sociedade; e o sistema hegemônico hoje é o capitalismo.
      Então discutir ecologia sem discutir como nós organizamos a produção de riqueza no mundo (capitalismo e luta de classes) é uma discussão pobre e que sequer tangencia os problemas em suas causas.

      Tecnologia é um reflexo da sociedade e está sujeita a ela. Discutir seriamente como a tecnologia servirá para salvar os ecossistemas é discutir seriamente como se fundamenta nossa sociedade.

      Leia Chico Mendes. Aprofunde-se no tema.

      @Arthur Knevitz Capitalism can protect lands should the market be allowed to function. how? Please read iPencil… It may have been one of Milton Friedman’s works. It was about the preservation of land because of the value it holds over time. Do you own any land and are you protecting any land? no, because you are an activist with a keyboard who votes in corrupted governments who control entire nations resources with debt based currency..

      Please please see that you are being played by government officials.

      Capitalism give you power to be the cure, socialism and corporatism give it to others. Dangerous.

      @walperstyle Eu esperava alguma colocação mais profunda do que “socialismo é ruim, capitalismo é bom”, mas infelizmente um pessegueiro jamais dará maçãs.
      O liberalismo é, de fato, a negação da realidade e com isso eu não me misturo.

      Tenha um bom dia e uma ótima semana.

      @Arthur Knevitz Sounds like you are just simply looking for an excuse to steal from others, and you’d probably vote to have someone do that theft for you. Entitled much?

    • Arthur Knevitz

      October 6, 2021 at 7:46 pm

      @walperstyle Em uma discussão séria eu colocaria todo o conceito de “roubo” em questão. Porém tu criou um personagem caricato na tua cabeça e atribuiu ele a mim pra ficar mais fácil de achar que tu tem razão de qualquer coisa que seja.

      O conceito de roubo tem mil significados sociológicos na sociedade em que vivemos e outros mil na sociedade que desejo construir para meus filhos e parece que isso ainda não tá muito claro pra ti. Assim como não estão claros os significados e nuances dos termos “capitalismo”, “socialismo”, “comunismo” e “estado de bem estar social”.
      Esses conceitos são importantes para a discussão séria que o tema em questão exige, então sugiro cautela ao sair tirando conclusões precipitadamente.

      Espero que tu tenha um bom dia e uma boa semana, entretanto. E continue nutrindo o nobre desejo de viver em um planeta saudável para nossa espécie.

    Yeah, find out what corporate Giants and small ones are causing the decimation and get to the source of the problem. Needs to be solved with a two-prong approach. On the front end exactly what you’re talkin about. And on the back end, going to the source and stopping it there.

      It isn’t just corporations, its unions and governments. The fact is, nuclear technology is here and can power entire nations should we get the government out of the way and let the nuclear scientists build them. The costs are high BECAUSE of bogus regulations created in the 60’s.

    • walperstyle

      October 6, 2021 at 5:14 pm

      disagree. if economics were allowed to function properly, people could make decisions with the money they spend instead of corrupt politicians. Socialism and Corporatism are evil, Capitalism is where you and your money and your customers decide the fate of the planet. To be honest, I would rather empower you than someone else…. yet I bet you vote hard every few years, expecting change.

    October 6, 2021 at 3:52 pm

    Planting is an incredibly important part of the path we have to walk! At the same time we must abolish the white-supremacist, capitalist patriarchy that is destroying our world! No amount of planted trees will outgrow this monsters destruction.

    Average human IQ is 85/90 this can’t be fixed, no matter how much though you plant 🌱… Humans are focused on safety, reproduction, and to stuff themselves to death, to actually remember something you need to first understand it and most people don’t get out of the circle eat , reproduce, be aware of danger. Good luck with saving planet Earth…

    ‘La plantation par drone et une IA formée à l’écologie’ !
    Imaginez-vous les transformations écologiques qui peuvent être engendrées par de tels moyens ? L’idée est belle mais de grâce, permettez à l’homme de planter lui-même là où il y a besoin et avec des graines primaires…
    N’oublions pas que ces déséquilibres et désastres planétaires sont, pour la plupart, la conséquence impardonnable d’actes de certains humains.

      Nous pouvons être des guérisseurs, ou nous pouvons être des destructeurs. Nous pouvons donner le bon exemple, ou un mauvais exemple. J’échoue souvent, mais je m’en soucie suffisamment pour essayer de donner le bon exemple. J’ai de grands espoirs pour que les humains évoluent au-delà de cette destruction. ^-^

    Any machine-flattened land should be returned to a disarranged state of irregular furrows and swales: flip asphalt chunks onto their sides at the bare minimum, exposing some soil and leaving a spot for standing puddles and high points for shade; increase the natural surface area geometrically, by breaking up the impervious straight flatness left by founders.

    Some words just shouldn’t hold hands.

    Why do you feel the need to defy gravity while saving the planet…it is not efficient unless your craft is lighter than air.

    Watch a kite club do their thing or imagine your goal using balloons, esp for payload delivery. Low tech that is no longer under patent offers economics to your project that may offer you more flexibility.

When Everett Knowles hitched a ride on a Boston train, he expected to make it home in a few minutes. But the result was the final leg of a medical history journey more than 30,000 years in the making when Eddy Knowles’ doctors turned tragedy into a medical miracle.

The path from accident to surgery required an almost impossible set of conditions to line up perfectly, and then it actually had to work. On the day of the accident, the wild scramble to harness expertise and to weigh calculated risks make for an engaging story of science and human ingenuity — but the truth is that the same exact process of discovery and daring is what forged the centuries of scientific knowledge that Eddy’s doctors used to save his arm.

Scientific triumphs and medical miracles happen every day. They just take thousands of generations to be born.
