sol, one that's also used in a growing number of buildings. the problem is our force and the supply of 10, but are under threats. thanks to climate change, model culture, plantations, and destructive pests. how about a natural solution? also coming up in the shows a someone found that protects the environment and its fiction recycling comp. i'd race of tricky and then you might think on a young business woman who recovered from so now the big balance of germany as far as this used to look like this. but now they look like this in just a couple of years. this decades old forest has become unrecognizable. the same thing is happening in many parts of germany, europe and north america. but this isn't too typical,

the planet is dying story. this could actually be good news. but to understand why, let's backtrack a little bit, maybe more than a little bit to the end of world war 2. a lot of the world is in ruins and needs to be rebuilt. the allied forces, understandably, you want reparations from germany, but it's broke. so they agree that the country will pay partly in materials, for example, timber, lots of timber, according to some estimates equivalent to 10 percent of the countries for us. so now for us does need to replant big areas asap to rebuild germany itself. and which tree did they choose? mostly the spruce, which looking back was maybe not the best decision. but at that time, it seems like a good idea to find out why we're driving to, to ring you in the center of germany to meet as far as the

defense. this navy is displayed and it's fast growing. regularly delivered straight high quality where they can easily be processed at sawmills into furniture flooring . it's used quite mildly, as is english, they have items and spa. that's why it's also a very lucrative treat german forest as planted vast areas with them in straight rows that make it easy to get in. and harvest spruce is of the most common tree in germany and make up over a quarter of all forests. but that is changing rapidly because of what made this one a culture so profitable is also what made it so vulnerable. forest around the world, us suffering from more intense and frequent drought, wild fires and storms weakening, entire ecosystems, and germany is no exception. the longest time is due to climate change mean, the forests are too dry, and the trees 1st, especially spruce street,

they comparatively need a lot of water, but the root system is quite shallow. so they comp access reservoirs deep down. while that's not the best news for the trees all for humans, and there is one little creature that loves what's happening right now. into the box. this tiny little insect has been munching its way through many of germany's in europe as far as the box. people of course, loves the box. it boils holes into the tree and then release his pheromones to draw a mate inside there they reproduce. emily eggs, a healthy tree usually produces resin to seal up the holes and to protect itself from the beatles. but stuff, the weak trees cannot. that's why the bulk beetle is having a fused. i don't from john bodies vision like what years ago this area was holy forest. and dyslexia, if we're standing here now, wednesday, last part of this area was infested in doing this. the or that area could also be interested in a matter of as, as the beetles eat away lias transport,

nutrients and water disperses and die of fast mel nutrition. the beetle is steadily spreading across europe and the halter it gets, the more beetles will breed. what a full scale infestation looks like can be seen in bach beetle central, which is the hops. national park in the middle of germany, where we're headed here about 90 percent of all spruce is opted. the bach people has come and gone, leaving behind the region. that is quite frankly shocking to look at. we're meeting the whole on peach, the head of the hots national park. the hots region is hit so hard because it had a very big concentration of spaces. but for peach and many others, this post apocalyptic looking scenario isn't a disaster. quite the opposite. for him, the bulk beetle isn't the villain. it's actually

a blessing in disguise. the 5 years the other question is what's happening later. but what's happening is that the old spruce trees are gone and the forest that belongs here is comic. when you see what kind of strength, how much life areas, and it's beautiful, it's great and truly exciting. here spend the pol, cut down the 6 and the forest as a safety barrier so that the beetle will have a heart of time spreading into neighboring forest. but apart from that, the national park decided to let nature be nature and did not fight the box. and nature is indeed doing its thing. different areas of the national park are treated differently. some pod square trees are springing up on their own left of their own devices like this area that died off about 6 years ago. some parts need a little bit of help, meaning formerly native species that were displaced by this person on the cultures of being planted. but that's just one part of the story. the national park is a protected area that cannot be used to produce tinder anymore,

but only around 3 percent of all forest and germany is protected. the rest is governed by public or private forest, as, for example, to produce timber. and we'll probably be using more of it since would can be a very sustainable and renewable building. material managed and grown by forest as like back into india. they need to take a different approach to the bulk b to the trees are checked for interest ation regularly. once and interest stations found the trees amongst them that are top down and removed as soon as possible to hold the spread of the beetle. leaving behind vast areas of prematurely felled trees. to prevent something like this from happening again, the approach here is to not only bent on one tree, but on a variety of trees by auction, it's like with a sophomore, you're diversifying your portfolio to minimize risk. that's what we're trying to do with the mix for as to why it, how this isn't equal. so should be

a scientist trying to identify the forest of the future. here are some of the candidates, 1st audio genes. beach ok, and sycamore trees are adapted to low elevations. they can survive with less water because they root systems are depo seconds of a new come out as like the douglas a native to north america. douglas fast can also handle more heat and droughts. these are currently seeing as good candidates, but if we continue to heat up the planet, we will need to mix in some wild cards to find out which ones may be suitable with the syringe and forestry has been conducting and now of a 10 year old experiment. in the driest region of the forest was this often to show it's more or less because in a mixed for us to have to deal with various species of trees or people each have different risks and costs. so its price here all the way through to the marketing of the word or other product, locked in for quotes with the home phone. but from our point of view,

it's more is that it's because it reduces the rent and just go over it with you. you might have more expensive, smaller yield and budget for the forest owner. yeah, it carries less risk because he's a corporate hosted thoughts. i see explained bites visits on this type of forestry, as well as the national parks approach shows where a lot of international forests could be heading. yeah, it's also a chance to adapting the change or speed up the 4th version. yeah. which would otherwise take much more time. it's best to get you off of on something that is, it's all good in terms of addressing the climate crisis and it's good for resiliency as well as bio diversity. ok and see if i would, even though it might look tragic, a new better forest is already starting to grow. one that is more resilient than what we created before. and one that will hopefully weather and adapt to whatever is going to happen in the coming decades.

some of them might not be the cheapest fish on the market, but it's a popular and relatively healthy options and comes in a variety of phones. conventional some of the phones have come on to fly up and using feet containing soil and you to pa, science to cause painful diseases in the fish. and no way one fish farm has taken an alternative approach. the fjords of norway, a popular tourist destination and now home to a new kind of salmon farm committee to doing things differently. the country supplies over half of global production to my smear hold is ceo of pack for the future, which operates the farm. whenever he can, he leaves his office to head out along the fjord to be with his team. to play, we're trying to find a new way of doing solving farming. and our goal is to reach the,

the utopia of having the world's most sustainable sound with farming. it's uh unlimited. even getting working proactively to mitigate the problems before they become problems like c lice, for instance. so we don't have any c lie, sir. and also with passages and 1st i seem to face parasites are a major problem for conventional farms. the specially slice, tiny crustaceans that can even cause mass di of someone there ost and they can also be transmitted to wild atlantic salmon whose stocks have plummeted by more than 50 percent since the 1980s. environmental list say it's a major problem. this is a very bad thing for the sidewalk in the times, but it's also it's a problem for the right side of them and the wind. so i'm in this area, is that the land think so i'm, i'm, and now is tracking or, and the increase in numbers i've heard is there a month ago?

another issue is that the fund fish often escaped through gaps in the net. if they then meet with the wild atlantic, salmon, they're off spring struggle, just survive. leading to a further decline in the ocean, going population and excrement from the aquaculture facility often pollutes the surrounding waters. that in turn promotes the spread of skin diseases and the fish . so what makes this 5 different? the key lies and its construction instead of being surrounded by nets, the fish pins are enveloped in plastic. or we have a, a protecting bowl like clothes and bag and up the faces in. and we filled that bag with water from the, from the deck. so it's fresh water from the depth. without sea lies. the aquaculture pins are made open impermeable plastic outer skin or bag ended net to prevent the fond fish from escaping ending during the wild, atlantic. salmon that double barrier also keeps license. other power sites

out of the pin the pins, get a fresh supply of water piped in from the cold steps of the ocean. where there are no sea lies. excrement from the fishes collected by a filter under each pen and then pumped to the surface. it's dried and then used by bio gas plants to generate green electricity or by farmers as fertilizer where the 7 farm or that i know that don't time. so you lice. and when the fish gets to just drive inside of a good environment through, you have very good growth. so you have very low mortality and very good quality of the fish that to harvest in 2023. the average farm

semen mortality rate across norway was 17 percent with infectious diseases, i'm major factor q. the rate is just 4 percent. thanks to a very low level of disease transmission. the boss shows us the filter systems that are installed under the pins in the assembly hall pump units are being built, which will then be well to together. the company has a patent on the high tech filters. this is outlets. so this actually regulates how everything is floating in the ocean and is also where we collect the floods. and uh, if you have any dentist, we can collect the tear it take you to store and, and use it for uh, another value experience for the future. so it's, it's making a profit and that it salmon is no more expensive than what sold by conventional producers or re purposing. the filtered sludge also helps in keeping

costs down the for now at least the semen industry is skeptical of the innovative young ceo will his approach bring a lasting, sustainable change to salmon farming. to him i smell holt is optimistic and is already hatching plans for an expansion. the you see a lot more that 2 vehicles on the roads, roads these days, even though you can barely hid them. and while regular models create not just noise, but also app pollution tvs have no exhaust, although they don't totally green the heat. this the c o 2 from that production plus the environmental impact of battery minerals mining. so how about just recycling old batteries? this little puddle good was once an electric hub. that's where you can. ford went

through all that the and know you have all the good stuff, cobalt nickel, mangan, these and lift him in here. and the idea is to turn these raw materials into a new venture where you get there are several ways, but this is one of them. first, the battery arrives at a recycling facility and gets discharged after it's taken upon the battery, then gets shredded. the liquid parts get expected and different methods of grinding and sifting leafy with these base materials, metals from the battery, housing, plastic and the bits of aluminum and copper. but the stuff that everybody is after is this black mass. this contains all the valuable materials, like lithium coal, both nickel and manganese, but also graphite. that's why it's black. and today we're going to get all of them out of there, but that's not my job. but there's, this is new come to

a doctor or research a add to close. todd and his chemical lab technician might, could come in at the university as part of a larger research group that is trying to figure out how to do this on a larger scale. and by the way, this is what the end goal of this process is supposed to look like. seeing metal foils, ready to go into effect 3 again. so what are we doing now with the black box? so now we're going into the leasing operation with the blameless. so we are bringing all the valuable metals we have on the blackness into solution. the metal way off today is called to bring that out. mike is using so far it as a, as a solvent. pretty nasty stuff. if it would touch her, i was going, it would instantly costs a via buttons. we're using a process called hydro metallurgical recycling. it's a low temperature process, but only use a small amounts of energy compared to other bets where your 2nd method. this entire process is perfect for getting rid of impurities that are still in the black moss.

after all, the shredding and sifting mainly aluminum and copper as a 2nd step, the black boss also gets filtered. lucas, as throughout the entire recycling process, they are able to remove 95 percent of impurities on a scale, a little bit bigger. the whole process looks like this massive parts of solving, in which black moss is process. our black mazda is now edits to a nother solvents that will help bring out the cobalt in this chemical cocktail. and it's pretty colorful from greenish to dark blue. it's like so blue, it almost looks like ink, it could like brighten with that. and it's this doc blue pod actually that the coal both sticks to to get a higher concentration of cobalt. we need to do another round of this. this time

we're going from blue to red. now that's a color change. so now the cult is in the dock a reddish box, but to be able to use the metal, a new batteries you of course, need to get it out of the solvent. you can do that by using it up as you would at, in the scale or a little quick kind of small up like this, with yet another solvent. really can see the crystals a lots here that even accumulates that the bottom like how much cold is that now from the bike mass isn't here, will actually leave of this technique. we are able to recover more than 99 percent of the cold. what are the biggest challenges in ops getting these process is what makes it so hot? you know, of course you, it, we also run the run through the problem that on that scale, we are only doing dozen pets. explain and so step by step, very common studies, but in industry you want to and money. so you have that you're having a continuous process and handling and continuous process of all the impurities and all the process steps and small things you need to consider. it's kind of

challenging. that's what other researches say as well recovering more than 90 percent of materials is possible. but this requires optimal conditions which you don't always find in the real world. if the recovery rates drop, the business case becomes even more difficult. when attended to you in the market is, is stressed to everybody minds who cycles by now the price of sorry, why know, which is a challenge for everybody who wants to was this investment basically is price is a high recyclers make more money, but the question is how much consulting firm mackenzie expects recyclers to make around $800.00 to $1600.00 puts on a battery. it's really about how much do you pay when you acquire the material. this is hans eric mel and he's been analyzing the ends of lock. that's remarket for yes. so if you get material for free and then you process it,

then sell it to market price, you able to use it and make a lot of money. you will most probably make more than many mining operations. but if we select those, what need to pay for the batteries? the economics can shake. this could mean recycling is more expensive than just mining new materials. and this isn't the only issue for commercial size ponds. another challenge, other materials used in the battery itself. it could be a whole bunch of combinations, lithium, ion phosphate, lithium, manganese oxide, lithium, the cold, cold mini um, or lithium, the cold manganese cold. and the last one even comes in different compositions. 121-216-2222 or aids. $21.21. it's the wild west out there when it comes to bed 3 manufacturing, which makes it more difficult to build payload commercial thoughts. the bottom line

is, and the real world recycling is much, much harder then on paper. another problem for recycling batteries doesn't have anything to do with the recycling process itself, but with the missing feedstock, electric car batteries last longer than previously sold and off so that they get used for all kinds of other things. like storing renewable energy, which means that does money batteries to be recycled or on a large scale recycling batteries is no issue at all. 9 to 9 percent cobalt because it's insane. but on a commercial scale, not so much info that for example, well, it's only going to do with a home food by products. so there's some questions that still need to be on the never found down on exhausted, due to work day after day. fun out is more common than many people think

on can even affect the younger generation for res. hope. even if it's main starting from scratch, we met a young woman who managed to make it come back. it's been the mice of the best model. the thing living proof of being able to make great money from a 6 hour work day, but also having another leisure time to enjoy life. in spite of them, the mom. she was 14, what you started a business degree and 16 when she found it. her 1st company, when i got i learned a guy and i started my 2nd comfortable that i was 18 and had 2 college degrees by the age of 20. but then i had about enough time to come, but remarkably, she founded her 3rd company at age 22. mr. white as a type of guy and justice from being able to study and set up a company that age was really liberating, is funds would not have the privilege of knowing early on what i wanted to do. and

i just couldn't wait to get started. the kids that i'm supposed to, i'm from wells her 1st company flopped, she was able to sell the 2nd edit decent profit and then developed an app for lifelong learning. and in company training the semester students, i knew my to insure children or shit for me, means creating something out of nothing and solving problems for people in scale. one, all the employees and having that huge freedoms, those creatively and how i set my own life to strive and come back to us all these my name all squished a truly precocious challenge and one who's already working on her doctorate while running her own company. being a highly challenging individual with a very high i q obviously helps when it comes to career advancement. but as with anyone else working too hard can lead to burn out syndrome. and i

remember feeling to myself, i'm not putting off myself. that experience was the inspiration for a new business idea. providing mental health support for other entrepreneurs, like the june labels a 3 month course costs $2.00 and a half 1000 bureaus. but is a 22 year old really in a position to provide coaching almost as long as i was just look at their track record and the fact that she darted quit so young an age exceeds commodity. you founding her 1st company when she was 16 is way ahead of main female. and of course, because the services are available online, the, when it was with the coach and the mines, normally coaching is one on one of the team. but there are a range of issues where a group approach works really well. it is on that journey. so i'm glad taking time out is crucial, but she doesn't feel like networking is really work which one is. and so basically

it's great just knowing i belong to by the yahoo, that i've been able to establish myself and be part of this. it goes to the one with what is the requisite loaner because he knows she's benefited from a lot of luck. over the years, she has supportive parents and investors interested in her work, and she's always open to reinventing yourself. i am not fit for this edition of my power assigned to do devastating homes of forest as well as to someone in fish farms on republishing the materials in comp, batteries till next time over and out the it's getting hotter and hotter. interesting. well, he's thinking mind this,

he's of backing extreme with because of telling a change, but also do you just that tiny, tiny is a no transforming these living spaces from great to green, building at best of employment. next on d, w. fighting overland, the, the confrontation between jewish settlers and palestinians in the west bank is dramatically increasing. the documentary takes a special look at the better when village of waddell seek the refugee camp notions in 2 hours on the w, the
