marine biologist analyzes the goals, are quite a see in the everglades to find the hello and welcome to tomorrow. today to dw science. agriculture may be responsible for some 15 percent of current global warming levels . according to a study by new york's columbia university. it estimates that food production alone could cause the climate to boom by almost one degree by the year 2100. the same as last week to blame this greenhouse gas is produced in the gusts of room and then plot stuck, chiefly counts we present of pharma who's trying to reduce his dairy farms. carbon footprint,

a christa cook and as a farmer who is constantly trying to improve in elaborate agricultural management process, not just to provide healthy feed for his cattle, but also to improve the quality of the soil underneath that we have grass white, clover red, clover, and herbs species, diversification is very important for humans build up. the bacteria don't feed on just one thing. humans building can only work with biodiversity. homeless building is just one part of his elliptic system in the kettle or at the center. twice a day they move to another paddick with tall grass and it has to be done at precisely the right time. the stocks are fresh, choose the food for the animals. everything is coordinated from the size of the area to the number of cattle and time. the grass and the product needs to be flattened down, but not stripped there. they probably left them there for just one day longer. they

would have eaten all the grass up, which might be a bad thing, but that's not what i want to happen. i want to preserve a mulch layer, here's the soil beneath the dead. flattened stock is always moist. the cattle contribute to this cycle by using their homes to stop on the grass, which causes the amount of homeless and the soil to increase. then organisms cause the volume after decompose binding with the carbon that plants consumed from the atmosphere via photosynthesis. and tony hope is turning hummus accumulation into a source of income. kristof tube ken has decided to participate in a private certificate trading scheme for each additional ton of c. o. 2 that he binds using homeless build up. he will receive 30 years. the traitors sold the certificates to regional companies that advertise their commitment to clement protection. but how is homeless build up measured?

the source locks. i'm just not as to why it's measured per field, which is around $2.00 to $4.00. hector's 25. so samples are taken from a depth of $25.00 centimeters and measured per gps. i don't know where the samples were taken from, otherwise that would throw a depos compost on each spot. after 3 years, we'll take more samples from the exact same spots, then we'll know whether it's humans has accumulated. this might help. it was awful about how modernist. soil is a huge c o 2 reservoir and that means carbon farming has a lot of potential to combat climate change. at the same time, agriculture is also a major c o 2 emitter, the scientist at the turn and institute and brown spike have done the math decry costs and its very biggest sources of greenhouse gas emissions from agriculture are nitrogen, nitrogen fertilization, which leads to nitrous oxide. and cattle which a mit messing cattle in cows and drained people. so it was that used to be pete bugs that are now used as farm land and grassland together. and these are meant

around 100000000 tons of c o. 2 per year in germany. i and i've sent a carbon farming, which you must build up. all could compensate for 3 to 5000000 tons of this making good climate neutral, which shows that it's not just enough to build up humorous. we also need to address these 3 major sources of greenhouse gas emission, what's included in some type house costs, initially on the con. crystal touch can is doing exactly that using natural feed additive, such as the horn pod, clover and reward planting that grows and his meadows and pastors. he's reducing methane emissions from his capital. he tries to ensure that as much climate damage and gas is captured as possible. this straw for example, collects common newer in the bars. this newer plays a central role in thomas and so management. this is our cat on the newer and

it's one of the essentials in our humans accumulation with all a and do convert them a newer and to humorous which causes the bacteria and fungi to proliferate considerably. we can use this compost to inoculate our soil later on. it takes weeks from a newer to become good compost, the process as labor intensive and time consuming, but it is central to sustainable agriculture. christopher clipton hasn't used a quote on his farm since 2018 because breaking up his soil loses homeless in the process. when the compost is ready, then come the next steps that we use this to inoculate. the soil implant which then perform photo synthesis and eliminate carbohydrates from their routes, which then feed the bacteria in fungi in the compost so that they can continue to multiply. and that's what creates the human will his conversion be successful? his green yields continue to fluctuate wildly. is ms cloud up?

it's not clear whether these methods will actually succeed in accumulating humus, exposing farmers to a degree of risk. they have to pay in advance for the human analysis and then hope that a 2nd analysis, 3 or 5 years later, will actually produce more humorous in which the certificates can compensate them for. but that's not a guarantee that this will actually work best as of i missed exact this disability from cindy yet for christopher to can. the certificates are a secondary concern for now. he has also begun to shift the way he practices agriculture because as an organic farmer, he doesn't use any fertilizers made from synthetic minerals. instead, he works of so called under, so in crops plant hybrids that he shows in the green field the when the green mature is it turns green again down here. and when we harvest the grain, what's left is a green lawn once again. so that's why the middle here becomes so green later on.

this field is also designed to create homicide. a report from the 1st 3 year period is available, which lists the increases and decreases. and thomas plot by plot. wherever there's slurry, we've had a decrease in humus and wherever there's compost, we've had an increase. we've collected 1500 tons of c o 2, using you most accumulation. i honestly didn't expect that much using compos to in rich soil adjustments that have paid off for this farmer. and for the climate, the cows always do just what they told. no cows, a highly complex social and sent in things even if through as a breathing we've transformed them into mill machines with huge out is that can give up to 15. these has of milk per day. the cows have

a mind if the say cultivate friendships and have finally changed sciences. so to get along with them, you need to understand them young boldly to make his fits. it goes mine on this coming to know past. my name is commander lopez and i'm 19 years old. i'm a wildlife filmmaker and photographer, so i'd like to understand animals better. wild animals interest me as well as photo genic unlikable ones like cows. but i'm not quite sure how to approach them. how should i communicate to the account that i come in? peace? what does it mean when they lowered their head? how can i politely get a count to do something? what does moon mean? i'm going to an organic farm near bayman to find out these dairy cows belong to a farmer. how are your camina benito visor is visiting as well?

he's going to show me help ciao. see the world english one. i'm excited. let's see how can see the world. okay, here we go. first i bent my head the way a cow does when it grace is young. okay. so there's only a very small range that's actually and focus on being the roots is on. i think what we built into the app is a wide field of vision like a 30 degree visual focus ahead, an ability to estimate distance right and left. but in the periphery, it's very blurry. corresponding to about 30 percent of our visual acuity. this field division allows cows grazing and meadows to get their bearings. but things get more complicated when they're inside their sheds. farmer how your cabinet is going to try out. seeing the cow should the way his cows do. who fits?

this must be the couch, sticks its head through here because it's curious. so if i try to do that, especially it's hard for me to figure out height. that's why i'm bent over like this. otherwise i'd bang my head, but i'm having difficulty engaging with here. it's all very blurry by having this panoramic perspective makes it very hard to invite videos here, but really finish. okay, and how was it? very interesting trying it in the middle was one thing. another trying it here in the stable cows don't see the world the way we do that. something we need to bear in mind as for how to get the couch to go in that particular direction. that's something to be learned later. first things 1st the best, but what does move mean will be, where are you or i'm here,

or i'm hungry or be helpful when you've worked with cows awhile since you start to recognize the different move, which is not. who is often one of the many signals of a particular phase in the reading season as positive ones. how did cows communicate between themselves? just with moos and you, under the eyes of itemize the company, most of the communication between cows is non verbal. ok. a bull that's defending its position to show its broad side when you put or lower its head to show off its horns to demonstrate that it's a threat. ah, nice didn't comp one, don't come out and speak to being, it's put in service. uh, the whole me, the poor guy, smart in the state of hudson's outback. we made an expert on bovine body language for a good depth, a few shows. farmers had to deal with their herds, to avoid stress, and avoid accidents. today though,

he's teaching an amateur, me the how do i convey that i come in peace, cisco to the think. well, it starts with how you arrive in the meadow. don't ever yell or wave your arms about titled can recognize fluid movements. and so if you're at the gate waving your arms around 12, you'll start to stress them out and put them on this test with as the mentioned after flip flop too. right. and if so, how would they respond to the way i'm behaving now? base for new q 50. well i think your voice is calm in the main seniors to keep your movements come to you go into difficult. uh. yeah, it's all for you as well. it was okay. i'm going to try and round them up. let's see if it works. so i'm trying to get the cows moving calmly steadily. the way i've been told, but they're not remotely interested the

. that's what you did well, you understood the techniques and went about it in a common study fashion and didn't try to rush it was so it wasn't supposed to be through the list and not that that. but now folks are depot, hasn't another task driving the black house, just the black ones out of the enclosure, the brown ones are supposed to remain inside the 1st of all, they get round it up. then they're divided into 2 groups. oops, one straight brown cow strays into the wrong group. we can live with that. so look what we've done with these ones are here. they didn't start to panic because we avoided things getting hectic. so what we did was we steered them using their

shoulder points. why do we approach their top vertebrae sideways on so that it turns its head in my direction side? and when i increase the pressure, it will usually go in the direction that they had this turn towards any sunday. the book ever brought this in life. i am what i end up with a coffee inside the cows have a personal zone. if you enter it, the cat will try to get out of your way. so that's how you can steer them. this is where you want the car to go. imagine a line running sideways from their shoulders and then enter their personal zone behind it. and notice the cow forwards. leave the zone as soon as you can, thereby rewarding the cow. as soon as you cross the line, it stops moving. if you stay there, it changes direction. just how close you need to get to it is up to you and the cow has each animal response differently.

the farmers are the only ones who need to pay attention to cow behavior. if animals get worried, they can pose a bit of a thread, even to passers by. but if you treat cadel respectfully said, try to see the world from their perspective. you'll get on just fine. that's what i learned from my day on the 5. the biodiversity is probably the exciting, more rapidly than previous meetings, significantly more plants and animals, the seasonal space. and that's the conclusion of a survey of scientists from around the globe headed by the university of minnesota to sit, i found that one and every 3 species could be endangered or extinguished by the

year. $2101.00 species that's already on district is the north american mounted. see over 1000 minus. he's died in florida last year alone. the ever great at the southern tip of florida. the biggest stretch of some tropical woodlands in the us, the this fresh water marshland is teeming with life. the everglades are a habitat for a wide range of flora and fauna. the region is home to extraordinary biodiversity, including manage to use their population, had been recovering after years and decline 2 years ago, researches counting around 8000 of the marine mammals here. but since then, there's been an unprecedented number of the amount of calories for 10 years pulse

stewart or captain policies known around here has been taking visitors on tours of the everglades. he knows better than any one where to find amenities over here. little ripple in the water, but the gentle giant disappears quickly. we go down the canal and come back to to this one. steward steers the boat through the mangrove forest in the western everglades. he thinks we don't see him at this environment truly has not changed in, in visual for about 40000 years. i mean, he's looking for food, it's low tide. the manages aren't the only endangered species here. there are no 3000000000 fewer birds in the us and canada. then there were 50 years ago.

over the past 10 years, we're seeing less and less birds are seeing a great reduction of mammals. small amount 80 percent are gone very concerning. the disruption of this echo system would be a terrible loss. these trees give off as much oxygen as a rain forest. they absorb as much carbon as a rain forest and they have all this change or, or be destroyed. i think if we would suffer the dramatically with climate change, the human population of florida is booming. all the new arrivals need somewhere to live. new housing developments are encroaching on the natural landscape. then we spot an alligator. it's about 1040 or 10 to 12 foot, one of the biggest alligators i've seen down here. that doesn't alter the fact that

this unique ecosystem is under threat. future right now. we better get on it because time is running out. there really is no manage the sightings today. we head over to the other side of the everglades to visit professor bryan lapointe. one of florida is leading ocean researchers, engine expert on this, frank, dr. eco system. last year we lost over a 1000 manatees. it was a record year from mann and c mortalities, and a lot of that was due to the star of ation of the man and t, due to the fact that the sea grass has had all but disappeared. manatees are continuing to die at an alarming rate that's due in part to pollution from wastewater treatment plants. many homes on the indian river lagoon aren't connected to the central sewer,

but have septic tanks. the waste water it goes down into the soil and then moves through the soil and groundwater into the indian river lagoon or adjacent water bodies. it results and outbreaks of algae that lock light causing sea grass laws, and that deprives them a real life, including manatees, of a vital food source, that is the primary food source for the man, etc. and so now that the sea grasses are gone, the manatees are starving to death. these developments are nothing new national story programs, the unseen menace is all about septic tanks. so this was done and as i said, florida today, 1997. and we knew way back then that the lagoon was already showing signs of septic tank pollution and problems. fish kills but nothing

happened. so this has been well known for a law for decades. yeah. it's nothing has nothing, not very little. i mean smalls, baby steps have been done, but nothing on the scale of what the problem requires. so we really need, you know, billions of dollars and a lot of time now to correct the problem in the entity ripple it go. lots of diversity happens for a reason, and once a species goes extinct, it's lost forever. if our blood is red, why are they? now it's your turn. do you have a question about science? send it to us via video, text or voice message. if we answer your question on the show, we'll send you a little surprised as a thank you. come on just dos. this week's question comes from

e. s. terrace. the why do some fish have stripes? while others have spots? they should been around for hundreds of millions of years today, these water dwellers come in a huge variety of colors and patterns. and now scientists can use molecular biology to examine exactly how this happened. the clips are particularly interesting for researchers because they have developed into a huge number of subspace eve with very different shapes and patterns in africa's lake victoria evolution happened at an amazing pace. within a few 1000 years, 500 these pieces of stick with emerged. all of this diversity can be traced back to a few ancestors that migrated from neighboring lakes. there are

a number of different habitats in lake victoria, and the sick was adapted to them. those that live among aquatic plants have developed camouflage, with vertical straits. while those that live in open water have horizontal stripes, which are beneficial when fish are swimming unprotected. these tribes make it difficult for predators to focus on a single fish. evolutionary biologists from constants in southern germany revealed the secret to how the sick looks. different patterns came about a long series of experiments brought males with vertical stripes together with 5 emails, with horizontal stripes. none of the resulting of spring had horizontal straight. the, these fish were then put together in groups with one male and several females. each . a quarter of their off spring had for santo straits. this happens only

one is the good inherits the striped gene from both parents in might've sick lives . the different coloring is probably caused by a so called jumping teen minus the clips are usually all born with dirt coloring. those with a jumping gene, vin turn, orange, yellow, or even white as they develop the. the color change from the dark to golden occurs when cells containing the dark pigment, melanin die off in the fish a skin. in reality, it's a discoloration caused by the jumping teen. that alters how proteins are produced in the scales. the researchers have been investigating how patterns and colors develop in fish for more than a 100 years. but there are still many mysteries to be solved. the
