why do we say there about never giving up every weekend on d, w, the forest produced oxygen stole water. i'm regulate the climate, but not enough as a surface is covered by trees. just 30 percent. many forest, something clear to provide phone land on climate change is also causing problems for woodland droughts, killing trees and encouraging wildfires. in places like canada rushed to greece, brazil. this time on the show, we take a deep dive into the forest on this future. welcome to the motor today in november of 2023 and there's fire in the pond to now. 2 the flames

devour trees in the south american wetlands region. solange, u. k, to enter team, look on stricken as the inferno rages out of control. they just finished a re forestry project here. so they will read them for you play music. it took the planets lifetime to create the content now, and we're destroying it so quickly. it's terrible more than that. the team was actually on the way to check up on one of their research fields. they were investigating whether the forest it started recovering from catastrophic fires 3 years ago, where there new trees were growing back. think it is as a guy, what if we had more trees? it would lower the temperatures here, guess from new trees can grow in their shade, but because there are no protected trees anymore, the young plants dry out. so spell, the last thing we'll need with climate change is heating up the ground and without

cooling, shade, a new generation of trees isn't growing. solange decatur says that the punch in our a patient, it would be sick, is a who and me and v as in the river is my life. i've decided to dedicate my entire life to protecting at this season. this the he punched and now in western brazil is the world's largest inland wetlands. it's a unesco world heritage size, around half the size of germany. the bio diversity in the region is done in the species that inhabited have adapted to a dry season, followed by flooding. and the rainy season water levels climb high above the rivers bags. and usa and george have always of, with this rhythm on the edge of the river during the floods,

fish find plenty of food and reproduce. river residents, both humans and animals live off that bounty all year round. but there are major changes on the horizon and they're worried afford is slated for construction here for shipping cargo like solely beans and cattle. the cyber county, where there's money to be made, things happen. so unfortunately, that's just the way it is. interesting. brazil is the world's leading exporter of the use on quarter is proud to had one of the country's largest cattle farms for him using the river to promote businesses the right thing to do. after all, every country is looking for economic progress. it brings in foreign currency, which brings prosperity and we're heading forever. cattle company land runs right

up to the river, access to a water route with slash transport costs. for farmers here, speeding up the time it takes products to reach pacific ports and ship to the huge lucrative chinese market models. what is the one for? it opens up the whole new perspectives. it's a sleeping tiger she goes and once it wakes up, everything will grow the inside. you put the c. c. solange, you, kate? a few years that more cattle and more so i will mean more deforestation and more heat river levels are already alarmingly low. now they're digging to deep and it's channel. and it will have to be dredged even more for cargo ships to pass. but that will help natural flooding, she sense of pressure the moment if the river is dredge down the water will drain away like and it can now forget the heart beat, the pulse of evan. flo will out here. sometimes if we lose these wetlands,

it will be a tragedy for brazil and the whole world to one of the p. then there are the forest fires, the region so more and november 2023 than any previous november on record. and due to and george are frightened, the flames are getting closer. sometimes they're just meters away. that is as possible. just seeing all the birds, all the animals dying on the whole thing. and there's nothing you can do up to the couple. wilson, for the 1st month that breaks your heart. i wanted to call you the key. it went through. does this bid on this and use it has been collecting seeds for so long as you k, to entertain for 3 years, enabling the scientists to replant important tropical training is. today, the fisher woman receives a seedling as a thank you. but only one thing can save the content now. yeah, well, this reforestation on a massive scale reforestation projects

and the european union making strides forward. but at the same time climate change as having this the impact on existing tree populations. many species are unable to cope with the rising temperatures and per long droughts that are going more common by the, on the changes on totally affecting money as far as money coaches in germany, researches and experts are thinking about how to make the countries far as fit for the future of the densely wooded south west of germany and the state of rhineland 11 at almost $9.10 trees over hill forest or fleet. please hang on. this has been monitoring the condition of the woods here for 30 years on schools is on or very worried about our for at all. so it's like a fever occurs when a fever rises. it doesn't mean a patient is dying, but it's an alarm signal. and we have to make sure it doesn't get worse,

that we do everything we can to help the patient who is good. so where did the experts take measurements once a year lead to those angles and his colleagues look at the health of the trees and the same $167.00 locations. and 15 of them like in this national park, there's no longer anything to check and those who on so many of the points where we used to take measurements are now stripped to pay. here, there are no trees left. something we've never seen before in our, for us to condition survey is unprecedented up to it is we are very concerned that the stance have disappeared over such large areas and it's making itself balance. and we really noticed that in our sampling grad school of us, the, the main problem is the bark beetle, which is spreading rapidly due to dry conditions. the insect has already killed many spruce,

and many trees that still look healthy are already infested and will soon die. although the tiny holes they make are barely visible, the beatles and their young drain trees of water. around 20 years ago, spruce is made up around a 3rd of all trees in ryan lunch. but a lot today, the red under 18 percent and numbers continue to fall to proportion of beach and oak is growing, but they're suffering too. so when is a tree considered sick experts to assess the condition of its crown and how dense its leaves grow? what is the leaves or needles look like? are they green or do they have brown spots? we do is you guys can tell at a glance and set an appointment. there are individual trees that we've been observing for years, which can survive unless something else bad comes a lot. like a bark b linda spruce or castle 7 fast to beaches and oaks. if that doesn't happen,

well tree may well live for quite a few years and so they can also recover. a typical example for that as b o, which retains a high capacity for re generation even if it experiences heavy leave. well i guess i see once i move in the hot of the forest here has been hit hard by dry spells in recent years. and pollution has also taken a toll nitrogen and sulfur oxides. enter the soil through precipitation. acid, rain and forest di back have been issues since the 1980s in space on the acid rain service software dioxide cause the soil to grow acidic plus the few alkaline elements and are destroyed by those ass on the claim. minerals were 2 and the bases were washed out, making a bad situation. one is with the for shelves. what could the forest of the future look like here? douglas, far as now,

often planted instead of spruce. it was stands, drought better grows quickly, and there's a market for its wood. but it says no single tree or solution can save the forest. us kind of fall off. for con, every 3 species has some kind of problem, but some things are important. it's bundled together. first you have to select species that are suitable for locations, ones that can cope with a soil and the climate. and then there's planting a mix of species, but you shouldn't plant as many trees as possible and ensure that there are at least 3 or 4 different species in the maxima swanson for sweet place and goes and others making german forests fit for the future will be an ongoing challenge in the years to come in kenya, a lot of trees will cut down for charco production over the years. about

reforestation projects are in full swing, an effort to replace some of what's been lost, researches, rules and monitoring conditions and wooded areas without official intelligence, the relying on goods to supply them with key ecological information as samuel goods. you is looking for birds, the ornithologist for 10 years national museums, pets to the field with his usual tools, but not killers of finally 2 deer and lots of patients. so, white ground grubbing chat, see it's, it's can have it calling. yeah. but samuel is not just here for a walk in the woods,

he's helping to collect data for the forest sensors. he looks for species that can help identify threats to the eco system. today, he hopes to find a bird called park labs to rocco. so buds like those uh for us to depend on cause the new rely on indigenous for assistance for the food and breeding and foraging areas. so when we lose pieces like the hot collab store, cool, we know that the for us health is in decline and may be, will indicate that we need to do something about that in terms of maybe reduce into fear around. so plant more indigenous fruiting trees in the area. but this data collection method takes a long time, spectacled weaver, when that's calling true. but when it comes to deciphering bird calls, even professionals make mistakes. luckily, a local university has developed

a device that can help researchers like samuel. okay, so this is an acoustic sense. i'm not too developed on this into for an adjustment and addition intelligence. all right, for i would do data collection with the goal of monitoring ecosystems using so we have us all up on in the do tags, the by chance. mm hm. samuel is excited about this invention. he believes that can help him and his work the machine learning powers. the technology, as well as most artificial intelligence, recorded audio is converted into visualized data, which has been analyzed and used to teach the system to recognize bird calls and other acoustic markers. this data can be very useful when it comes to environmental decision making when it comes to equal systems such as forest uh, bugs, uh,

good indicator of the forest health. hey, i tools can help quickly determine whether a hardship, ego systems need help. for example, in the form of reforestation like here where more than 30000 indigenous trees weren't planted and a habitat degraded by charcoal production and agricultural encroachment. the trees are monitored and tracked over time the but manual monitoring is time consuming. so this scientist use is a special tool and a high powered stereo scope. and we've got to dream it is of trees. and it is possible from 2 images to sort of acquired the depth of the points on the scene. you know, just know how far the points of how to the out of the ground, the inside thing. so it gives us sort of a 3 dimensional understanding of the scene in front of the coming of the software

called tree vision. automatically measures tree height, width and other features. the data collected can be used to project the amount of carbon that can be stored by a growing patch of forest, just like the designs for the file acoustic microphone tree vision software is open source. so other researchers across africa and beyond can freely adapt it to help keep ecosystems intact. the trees can be found practically everywhere on this, and they come in many different shapes and sizes. there's a huge range of species, and scientists still have a long way to go to identifying them all of the mold and $73000.00 trees. species that are thought to exist on estimated $9000.00 have yet to be discovered or described. not so the bread, not tree it secrets will reveal long ago. columbia is tropical drive for us cuz

home to many unique animals and plants, a very special tree also grove is here. it's a very, very important tree in the tropical drive for us that provides food for bern, rodents, mammals, and human ski model is the guanajuato is also known as the tree of life. is the, this comes from the flower, the fruit, a decline model of the tree. see your notes are highly nutritional in them. they contain amino acids and proteins and they also have a lot of calcium in maternity concepts. why moto is currently being re discovered by colombia is color and everything. and that's helping with the reforestation of endangered woodlands in lab. and this giant tree is called pro seem other costs truck. but it has many names why motto is also

known as i'm on the home page, the bread? no, it's for maya not tree. it's thought that it's seeds played an important dietary role for the ancient maya. it's found in central america is dr. forest areas for colombians like heavy jose is a key to it's an old acquaintance in any ask when the a will make it. well, i've known it ever since i was a child who left property that when my grand father or took us home with him, he taught us a lot about the g y model is nutritional and physiological aspects. we children ate them. we harvested the nuts wild in the forest and ate them raw or cooked. yes, they nourished us even as a child i knew many ways to prepare them. now i know that the tree has even more great properties and so it has even more value for me that the model of the wind model seeds are harvested with the help of the animals that live in and feed on the

tree. it's considered an umbrella species, as it contributes to the survival of numerous other species in the same habitat. the double 0 san francisco bags eat the pod that contains the not less people say the pod. well, that's not the see. this was about drops out along with some birds available. we gather them up from the ground and bread and thousands of recipes just as you like, nickel 2nd, to get us from the jungle to the table. that's the motto at this gordon, a restaurant and the colombian capital chef on 20 larissa has discovered that why motto flower can be a versa tile ingredients in practically any dish with quite a bit. that's a very universal products because it's a ground powder red and plus you can use it as a kind of coding. for example,

i find that today i mixed it with you to make the dough from my end panata. it's very, very easy to use and it has a really special taste one that's unfamiliar dealing with one. so i think it's almost never use this one. and despite the fact that it's silver's a tile static, because the flower can be used in many different way as well, particularly in the living waters. my name is twine model is very aromatic with a smell similar to coffee sentiment, not meg for chocolate. so it's ideal for ice cream is not it is, it's like a 2nd we've been in our ice cream recipe seeks to emphasize the special flavor of united way and get any and it helps us introduce it to people who may have no idea what. why model is better, so they get to know it for the 1st time. and then of course, that's the one of the collaboration with a scientific community is important to ensure that guests appreciate the novel

product those historical nutritional terms, the seems that the bread no tray are really packed with healthy components. studies have looked at that as well as anyone else who put forth the results show that it really is a kind of super for me. and we want to share that realization with everyone that meant that going but be to the point of the month. but it's on the, at the alexander fund, humble, biological resources, research institute. and then they have a monica flores as doing in depth to work on quite a model. she studies meds, tales and legends about the tree in indigenous communities, as well as it's nutritional value and many uses. the glowing motto is a member of the motor. see a family plans that are characterized by the fact that their lease produced a milky sap called latex dinner, but it's also think that it's on fiscal may say. now the plan also has some

additional properties. let's step on it. the latex can be used as an hour and for some wounds, and let this 10 minutes the lease out. it's also used to cleanse. the stomach rises, the less plan to left, the can, and the restroom. why moto seedlings are used to treat your logical conditions? and to purify the blood, so i'm going to get to the phone today. over 40 percent of the seed by weight is protein. it also contains a lot of iron and healthy omega fatty acid. this gives a great potential as a products that can help insure food security. also a lot more flat, almost on the single tree can bear a lot of fruit in one season. this is a play. you can even substitute it from me or other proteins. ok. and it can be a food source for a very large population. a single tree can feed a lot of people into for me. therefore, it's a super for me. she is all for that. he meant the seeds are not only strengthening

the economy in rural areas like over the highs, but also highlighting the importance of columbia is tropical dry forest. an eco system under threat from agriculture and livestock farming. the enormous roots of the guanajuato tree grow very deep. so which resistance of both drought and fire making it an ally and the fight against mel nutrition in an era of climate change? or if i was what is read, why? now it's your 10 go to science question, then send it to us as a video, text or voice mail. if we answer it on the show, we'll send you a little surprise. it's a thank you. so go on. just ask this question came from you'd be in gun in the why is the length of a year and different on every planet a. ready lennox,

or that are song and they do so in more or less elliptical orbit. most places on earth we experience a year through the course of this. only around the equator does weather remain largely the same all year round. and astronaut nicole terms a year is the period of time it takes for a planet to complete a single orbit around the sun on earth. that's 365 terrestrial days. this has to do with our distance from the sun. it's so far away that our planet has to travel 940000000 kilometers to complete one orbit. vast in size compared to the planets, the sun exerts enormous gravity to remain in a stable orbit. the earth must circle it at a very specific speed. 30 kilometers per 2nd. if our planet moved any slower, it would get closer to our star,

the if it went faster, it would drift further and further away. the duration of the year therefore, depends on how far away from the sun planet orbit as well as its speed. the closest of the to the sun is mercury. it's orbit as much smaller than that of ours . because it's so close the ascent to the sun's gravity are greater, their mercury must orbit the sun faster to stay on track. it therefore covers less distance at a higher speed. a year on mercury only lasts $88.00 or states the farther away a planet is from the sun, the longer its orbit and the slower speed. it might sound hard to believe. but a year on the outermost planet net to last for almost $165.00 of hard years

honors the tools so this time around. but we look forward to seeing you again sometime soon on tomorrow or today. bye for now, the
