since then, he has been hard at work, and mingling with the people is at the top of his agenda. your room 13 d w. as he's got any issues or thoughts say what? the nature is beautiful and useful, but we useful to nature. what plans should we grubby now? cities to support local ego systems. how can we keep snails out about vegetable gardens without harming them or other creatures? and how can mushrooms help us give something back to nature of 12 days old us and

move, coming up the hello and welcome to tomorrow. today the science show on dw, and later, like this is full of activity. flowers blossoming foss applies. flying on please humming scientists. have proven that foam 9 meadows serve as a source of food. a habitat for polonaise is asked as coffin sinks and help to replenish gronvold. as i say, that's especially true when a wide variety of plans can be found there in large numbers. but doesn't matter whether the various phones on native species will come from other regions, right. a lot the to biology is doing and the got

incentive and they don't even have gotten they are looking for what's on offer for guns and balconies. julian, seger and english daughter are on a mission to safe native plants species. the idea of a concept is that we want to harness the numerous potential of millions of green areas that we have in germany in other countries like germany. so we have gotten a lot in men's side walks balconies. it's all spaces where there are people living intimately with these spaces where people are interested in planting things in the spaces. and what we want to do is re direct those efforts towards native plants that are threatened at risk of declining. already all declining is most unique. his plans, they have cultivated in the oven areas around the world. it could help to slow the

decline of biodiversity. but why is the focus on native plants so important? currently recount 13000 non native plants and the entire time diversity is 370000 plants. so see only supports new sites. so the non native tons, then we only support a small fraction and these cons already managed very well to disperse, so they are not at risk. where as many native tons of are at risk in gemini, around 30 percent of native plows are endangered. landscape architect jody effect until he goes to the x with trees, traps and flow. in his experience, customers don't usually ask for native or exotic plants. they just want hottie plans that are resistant to disease and easy to care for them both does she prefer

to plot your view and not to this sean. they are struggling because of course we make our selections based very much on the design, depending on what people want it most indeed or does so 1st look at what people want. i can then we look at the location just because they are all really different . it's one of the funds knowledge. then we choose the right plan, advisors present, for example, that can tell originator loves. so for electronic along 4 species that are able to cope with less water, the affinity will also suffice. calling. it boils down to a mix of native and non native plants. when people do ask about native plants, they usually amine plants that will support in 6 and betts safe. claudia, if it can take up and he into god and center they are a lot of insects, but not putting they just more attractive to exotic are native plants, guests of all gone to so as of us video, but i can't really say is that what we see here is that insects like going to non

native plants live on the appliances, because sometimes these plans filled the gap when native plants are taking a break from sun. mm. no pose only on the stuff that probably makes most sense is having both variances and follicle. so native species supplemented by non native one solution, i can think of different lenders and all that collect the x and the live solution. nitro, or a history was you use a specialist, an invertebrates which includes insect. the museum has around $300.00 falls and in its collection. does he think non native plants are a problem for native insects? a consensus is complicated and it's not a problem. when a new species appear is positioned, the question is always how they fit into an existing eco system, please pool. and that is very difficult to predict in advance of causes. because in

a new eco system, they encounter many species of animals and plants that they are not prepared for sized you so we don't know if there will be negative or positive impact, see or no impact at all. kind of also cool. have in the world about wild beast, comfortable if i'm not, depends on how good they are at dealing with the changing floor of course. so there are generalized among wild bees. for example, many bumblebees can use a wide variety of plants for food, but there are also many beeson bumblebees that cannot vary depending on a small number of plans i'm going to use. and when those plans disappear. so to the bees collect dorski is also a biologist, and t 2 is concerned about protecting bio diversity. what looks like a god and when nature has been left to its own devices, it's actually the result of gardening, the emulates nature. but the plans here primarily native species like most out and

deals in c, g of want the most like so what did you find and how much the non native plants we have here are mainly crops plans. for example, we have 6 you on pepper nice pins. that's which can be used as a spices and that's for then we also have fig trees suffice. provide and we harvest the fruits on to the high mission flower. native plants are primarily for the animals. so like these wild areas here by the pond to a non flashing and you have the semester presenting ties. um, but of course as i mentioned, there are also native plants that we use like ment, myself to you. i mean, so the mix of native and non native plants seems to book well for many animals like these drag and flies, these and visit an extra god and has many advantages. but it is a lot of look at god and is need to be knowledgeable about the plants, english, the interest in c, g,

a like the natural god. but does it live up to the idea of god that supports native plants and equal systems? i think the best racial is probably to have between 10 to 20 percent non natives new fights and the rest 80 to 90 percent native species. and especially for the new fights, it would be desirable that they kind of fits into our ecosystems as well. so that insect pollinators recognize the spacing. there's still one big sticking point. according to researches people's perception of what constitutes a beautiful god, needs to change it. maybe it's helpful to note that a god with such a mix of plants could bed to survive climate change even a well planned and implanted god, and that's

a good to combat climate change may be no match for snails. and no wonder why there are over $40000.00 species of snails and they can be found everywhere in the sea, in fresh water and online ponds. i love to eat with a native plants or exotic species, snails love them all. so do we stand a chance of keeping them most of all gardens? now that's what you call moving at a snail's pace. smell this big travels at 0.003 kilometers per hour. that's just 3 meters an hour. and it's carrying quite a load. the show on it's back, provide shelter when it's too cold or too warm. and this hole in the front door allows the snail to breeze. their eyes are also fascinating. an antenna

extends outward like a telescope. though the eye on top can only tell light from dark, but snails have an impressive sense of smell and can tell when something tasty is growing in a garden. snails not only love to creep around, they also love to eat a lot. they consume their weight in food every day. never races, appetite often causes conflict and makes them the bane of every gardener. the little smells are not the same. those with the shell help to keep gardens healthy. they feed mainly on dead plant and animal remains. playing a key role in homeless formation while cleaning up the garden at the same time.

only slugs, essentially, snails without shells are considered garden pest. like the spanish slug. how can you combat slugs? most methods focus on killing the intruders, but that affects both slugs and snails. the like household solve is especially brutal slugs died painfully from dehydration and beer traps are so attractive that they lower snails from neighboring gardens. even organic slug pellets made from ferric phosphate can be harmful to snails, natural enemies, such as hedgehogs, mice and birds. it all depends on how many sales they eat. what's the right method? covering plant beds with dry material is one alternative to gathering up and relocating snails each day. sawdust, egg shells, sand ash or dry coffee ground or tough to slither across. slugs like

a damp predators like run their ducks aren't especially effective, but labor intensive option. one else aren't familiar with the sand of cinnamon. it keeps them from smelling let us when she leave it. and once a smug has tasted a plant with chile on it, it will never go back and word gets out as quickly as will sprinkle the mixture over the bed and put some on the leaves, some of the soil it's non toxic. but i'm advertising for slimy. let us thieves sales are a minor problem compared to the major threat posed by climate change. world wide droughts and dr. periods are increasing, often leading to crop failure, bus and the long term red ground also poses an x. the central problem for micro organisms, plants and animals, and therefore for us as well,

much research has been conducted to find remedies in switzerland for example, they're looking for ways to make the best possible use of what was said in agriculture. water is a precious resource. phillipe, on a, it's a research or at the switch center of excellence for agricultural research or agro scope. he has been ideas about how to preserve water is your 1st good on no more important goal is finding the right amount of water adapt so we can use as little of it as possible for irrigation loss to achieving the best possible while it was able to pull out the mayo objective, cutting that monique is working on a drip irrigation system. for orchards, each tree needs a little more than 12 leaders per day and using the right amount in the right places helps conserve water. your thoughts reminds me of an australian publication

which demonstrated that drip irrigation can reduce water us by 50 percent to discuss cycled for someone do other studies may be less optimistic, but all of them come to the same conclusion. drip irrigation is an efficient method of distributing water to fruit trees, especially when used in combination with ground sensors. to separate sensors at different depths and the ground measure, it's moisture. when the song gets to dry, the sensors send out the signal indicating that the tree needs water. the signal triggers the watering system up to 3 times a day. monet has conducted trials on 30 different fields, and he's developed a fully automatic irrigation system. it prevents waste and guarantees high yields sales call. we are in a part of the more charity that for experimental reasons is like we haven't irrigated at all. is it due to how scholastic could the fortunately observe is that

the fruits here is not only small, it's not the best quality cutting t the produce 0 in terms of 1st choice that would cost to grow or tens of thousands of frames per hector in income mass of weight that deal with the over new port of the product of the drought is noticeable between the trees or the dry summer has caused major problems with these trees have died if they hadn't been irrigated over by the cold. yeah, the to show you how long the treatment survived without water. in fact, a tree has some mechanisms that allow it to survive without water. do you need them a dispute of assorted without water? they stop growing and can't drive quasi the prison difficulty. the growth of the shoots in the branches will be completely stopping as well. the growth of the fruit, a copay tool,

a that costs of the flu. so it's the yields the quality of the production that is affected by the lack of water. he fixed the bottle of bodily, moved aside from sewing improves. there is another way to measure entries need for water. didn't draw matters. a research project by monet's colleagues measures the diameter of the tree trunk during the course of the day. the trunk expands or contracts. when the sun shines, the tree loses water and becomes dinner when watered in the evening, it expands again overnight. if a tree doesn't get enough water and cap regenerate and experiences, what's known as water stress that has a negative effect on yields. the researchers and irrigation system is faster and more precise and also more reliable. so when the irrigation is well adjusted, it ensures that human errors won't occur. it's often valves that people forget to

close, that lead to waterway story funnel these uh bus going to be, as water becomes a scarce commodity around the world, water saving technologies like these are more vital than ever. mushrooms have been around for longer than humans. the oldest fossil fungi discovered by researches is some 700 to 800000000 years old. the mushrooms pop up every way. i can do amazing things to affect quantities even of interest to undertake his mushroom. i see him can be used to make things like bricks and houses that are really stable. some guy can decompose volcanic materials, including complex life forms. a lab coat, rubber gloves, safety glasses, some wood shavings. i'm phone go spose from the laboratory. mix them together,

add water, and wait about so bump hendricks needs to do to grow well coffin, i think of david as a brother, david at grow and gratitude. burke would be fans of my mushroom. my celia, i'm coughing the stage, but it's an invention for folks who think about the generations to come on new after their day. want to be one with nature and it rich, the soil is complex to will not contaminated human come past. is that a disrespectful or brilliant? i did the young industrial design. it invented his mushroom. my cellular coffin almost by accident bus studying architecture. he dealt with living building materials. since my cell, you can be used everywhere. the level lay my celia brings life back to the soil, so it grows fast. it needs no electricity, heat nor light. in fact, even absorbs c o 2 while it grows only. so the more people who are buried this way,

the better it is for the or 8 that's fundamentally different to our burial rituals today, the product of auto and just 7 days the, my selling them grows in a pre formed mode. forming a living coffin who surface feels like a velvet cushion. the coffin is then dried to stop the growth fund guy, then lie dormant. as the coffin looks like a star from books and it's just as light, but it's a completely natural product. that is, it's a solid is what special is the emotional perception when you touch it. so it feels good. it's warm, soft and light, but also very stable. yeah. so the coats inside can be will most to me to tool way up to $200.00 kilos for the barrier. it's placed on a bed of fresh moss to speed up the decomposition process. the moist most comes

into contact with the dried my cellular, bringing it back to life. more than 100 people of already being buried in my cell. him coffins in the netherlands. last year, a funeral director john phone custer episode the 1st living, coughing for an a 2 year old woman. the mice selling them based versions cost 1500 year is cheaper than conventional coffins. they need to know the demand. so i don't think people choose of my ceiling, i'm coughing for financial reasons, my rather they want to send a signal to the rest of the world. we almost do our part and only leave a small carbon footprint behind on this planet. and ovals are plenty of to live because around the world, some 160000 people die each day and they leave traces behind. not just in the hearts of the loved ones,

but also is toxic substances. one of the most resource intensive burial methods is the classical christian ceremony with a wooden cost get each year thousands of tons of wood, steel, bronze, and copper buried underground. the commission isn't much buses in europe, around 70 percent, as people know choose to be true. maces, however, this produces home full emissions and toxic ashes. at the symmetry, it can take up to 10 years or more for a corpse to fully decompose in a traditional wouldn't cost it. by contrast, with the living coffin, it takes just 2 to 3 years. and at the same time, the mice selling them release as nutrients into the soil for new plants. so what about this duction? invention has spread quickly. more than a 150 funeral homes took advantage of the opportunity to learn about the idea of

who panic burials from both. hendricks himself. he starts and we convince funeral director york few vague from kids a live of strong torch with burials desk and morning flowers and sustainability as a really big topic came on. it's also one that seen a huge boost in recent years when you can. i think it will become even more important toys because the people who are barriers you and me are the ones who are on the streets demonstrating with credit every friday. but today's house as also stand inside act i'm on the on. even if some people aren't yet ready for more sustainable burial culture club, hendricks and other funeral directors expect that soon. many would choose living coffins as that way of giving something back to the uh, the best. uh, also posit this uh, club life. they help to spread plant seeds,

they eat insects and keep the numbers a tech. some even seen quite nicely on so often do that from as of the heights, power lines are a popular place for flux. if the to land, which seems rather risky. that prompted view a how much say a to send us the question all the way from colombia why aren't birds electrocuted by power lines. busy power lines offer birds are lofty landing spot, but they've chosen a high voltage looked at more than 100000 volts flow through the cables. by comparison in europe, normal power sockets have just 230 volts. that means the voltage of their perch is more than $400.00 times higher, and yet i was feathered friends. don't even notice. nothing will happen as

long as the bird touches only one cable. no electricity flows through the bird because 2 neighboring points on the table carry very little voltage. birds can relax and enjoy the view. thanks to the principal of of electric circuits. they function like this. let's use a single wire to connect a battery with a light bulb. nothing happens. electricity doesn't flow through the light bulb until we take a 2nd wire and complete the circuit causing it to glow. when a bird sits on a power line, it's like a light bulb, with just one wire. nothing happens because power lines are like positive poles. electricity can only flow when they make

a complete circuit together with the ground. a negative pole that's the reason power lines rarely pose a danger to smaller birds. busy but power lines and transmission towers can be troublesome for larger birds. busy like eagles, storks, these and even crows every year, thousands of birds die from electrocution in germany alone. that can happen when they touch 2 cables with their wings and create a short circuit, or when they touch both the tower and the cable. the circuit is then complete and high voltage electricity flows through their body. the, this, these are appears to have been one of the lucky ones. it hopefully just got a minor shock because what is read? why are they if you have a science questions, send it to us by video,

text or voice message. if we answer it on the show, we'll give you a little surprise as a thank you. the just start the, that's it. so this edition of to laura today, the dw sign show, it's nice that you can join us until next time, goodbye. and remember to always stay to reuse the
