Moved coming up the hello and welcome to tomorrow. Today the science show on dw and later like this is full of activity, flowers blossoming, fire supplies flying and please humming. Scientists have proven that farm land meadows serve as a source of food habitat for pollinators. Act as coughing, sinks and help to replenish ground water. As i say, thats especially true when a wide variety of plans can be found there in large numbers. But doesnt matter whether the various phones on native species will come from other regions who walk up to by knowledge is doing any got incentive and they dont even have gotten they are looking for whats on offer for guns and balconies. Julian, seger and english started are on the mission to safe native plants species. The idea of a concept is that we want to harness the numerous potential of the millions of green areas that we have in germany in other countries like germany. So we have gardens and loc mens side walks balconies. Its all spaces where there are People Living intimately with the 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 of the native plants that cultivated the oven areas around the board. It could help to slow the decline of by diversity. But why is focus a native plants so important . The currently recount, 13000 non native tons. And the entire time diversity is 370000 plants. So the only support new fights. So the non native tons, then we only support the small fraction and these tons already managed very well to disperse. So they are not at risk for as many native tons of are at risk in germany around 30 percent of native flaws are in danger. Landscape architect jody effect until you guys ex, with trees traps and flawless experience. Customers dont usually ask for a native or exotic plans. They just want hottie plans that are resistant to disease and easy to care for in both. Does she prefer to plot your video . Not to is showing they are starting because of course we make our selection space 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 theyre all really different. Its one of the phones most. Then we choose the right plan, advisors present, for example, that can tolerate sheet or loves. So for lifetime ecolog, for species that are able to cope with less monitor the video also to westcan. It boils down to a mix of native and non native plants. When people do ask about native plants, they usually mean plants that will support in 6 and better safe claudia for a complete and he, in the god and center they are a lot of insects, but not putting they just more attractive to exotic or native plants. Guests of all gone to so as i say, you cant really say what we see here is that insects like going to non native plants will bundle defrances because sometimes these plans filled the gap when native plants are taking a break from sun. Mm. No pose. I am leaving on the stuff that probably makes most sense is having both variances and follicle. So native species supplemented by non native ones, i can think of different lenders and all that kind of said the x and the live station, Natural History museum, use a specialist on 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 concept, this is complicated. Its not a problem. One, a new species up here is a position and the question is always how they fit into an existing eco system, please pool. And that is very difficult to predict the advance one 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 dont know if there will be negative or positive impact, see, or no impact at all kind of holes feel cool have and what about wild beast . Comfortable if i need to put that depends on how good they are at dealing with the changing floor on of course. So there are generalists among wild bees in, for example, many bumblebees can use a wide variety of plants for food. But there are also many beeson, but movies that cannot vary depending on a small number of plants. 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, its actually the result of gardening, but emulates nature. But the plans here, primarily native species like meshed out and deals n 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. Most pins thats which can be used as a spices and scripts 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 present in ties as well. But of course i know to do. 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 very well for many animals like these dragonflies. These, it isnt an extra god and has many advantages. But it has a lot of look at god and is need to be knowledgeable about the plants, english, the over the interest in c, g, a like the natural god. Or does it lift up to the idea of a gun that supports native plants and equal assistance . 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 the insect pollinators recognize the spacing. Theres still one big sticking point, according to researches peoples perception of what constitutes a beautiful god, needs to change. But maybe its helpful to note that a god with such a mix of plants could better survive Climate Change even a well planned and planted god and thats equipped 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 unlocked ponds. I love to eat with a native plants or exotic species. Snails loves them all. So do we stand a chance of keeping them most of all gardens . Now thats what you call moving at a snails pace. A smell, this big travels at 0. 003 kilometers per hour. Thats just 3 meters an hour. And its carrying quite a load the show on its back, provide shelter when its 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, to the eye on top can only tail 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 loved to creep around, they also love to eat a lot. They consume their weight and food every day. Never races, appetite often causes conflict and makes them the bane of every garden. The but all smells are not the same. Those with a shell helped 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 past. Like the spanish slug. How can you combat slugs . Most methods focus on killing the intruders, but that effects both slugs and snails, the like household solve is especially brutal slugs die painfully from dehydration and beer traps are so attractive that they lower snails from neighboring gardens. Even organic slug pellets made from ferric. Prostate can be harmful to snails, natural enemies, such as hedgehogs, mice and birds. It all depends on how many sales they eat. Whats the right method . Covering plant beds with dry material is one alternative to gathering up and relocating snails each day. The sawdust egg shells, sand, ash or dried coffee grounds or tough to slither across. Slugs like a damp predators like run their ducks are an especially effective but labor intensive. Auction a one to one mixture of chili powder and cinnamon works to, at least in countries where snails arent familiar with the sand of settlement. 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 where it gets out as quickly as will sprinkle the mixture over the bed and put some on the leaves, some of the soil. Its non toxic, but im 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 by the long term re ground. Also, it poses an x, the central problem from micro organisms, plants and animals. And therefore for us as well, Much Research has been conducted to find remedies. In switzerland, for example, they are looking for ways to make the best possible use of low set in agriculture. The water is a precious resource. Felipe, on a, its a researcher 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 the 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. Why would we save the pull at the end of may you object . Hes got any thoughts. 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 cycle for someone to 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, its 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. Monday has conducted trials on 30 different fields, and hes developed a fully automatic irrigation system. It prevents waste and guarantees high yields to just cause we are in a part of the more charity that for experimental reasons, like we havent irrigated at all. Is it due to how scholastic, the fortunately observe is that the fruit here is not only something on you. Its not the best quality cutting d, a producer in terms of 1st choice that would cost to grow or tens of thousands of francs per hector in income loss of what that deal to all over new port of the product of the drought is noticeable between the trees the dry summer has caused major problems with these trees have died if they hadnt been irrigated over by the cold. Yeah. Do to show you how long a treatment survive without the water. In fact, the tree has some mechanisms that allow it to survive without the water damage disunity of assorted without water. They stop growing and cant drive quasi that prison. Digital p, the growth of the shoots in the branches, will be completely stopping as well. The growth of the fruit, a copay tool, it costs us basically. So its the yields, the quality of the production that is affected by the lack of water, the it, the fix, the bottle or bottle moved to aside from so improves. There is another way to measure of trees need for water, draw motors or Research Project by monets colleagues measures the diameter of the tree trunk. During the course of a 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 doesnt get enough water and cap regenerate and experiences, whats known as water stress that has a negative effect on yields. The researchers irrigation system is faster and more precise and also more reliable. So when the irrigation is well adjusted, it ensures that human errors wont occur. Its often valves that people forget to close, that lead to water ways to respond to these. Oh, thats cool, no, be, as water becomes 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 fun guy discovered by researches is some 700 to 800000000 years old. Mushrooms pop up everywhere and can do amazing things. To us the qualities even of interest to undertake his mushroom, i see him can be used to make things like bricks and houses that are really stable. And some guy can decompose volcanic materials, including complex life phones, lab coat, rubber gloves, safety glasses, some wood shavings. And phone goes bose from the laboratory. Mix them together, add water, and wait about so bump hendricks needs to do to grow a coffin. I think of david as a brother, david at grow and gratitude. Burke would be fans of my mushroom, my celia, im coughing these things, but its an invention for folks who think about the generations to come on new after their day. Want to be one with nature and 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 cough and almost by accident. By studying architecture, he dealt with living building materials. Since my cell, you can be used everywhere. The end of this little lay my celia brings life back to the soil. So the grows fast, it needs no electricity, heat nor light. In fact, even absorbs c o 2 while it grows. Cool. So the more people who are buried this way, the better it is for the r 8 thats fundamentally different to our burial rituals today, well put it to the auto. And just 7 days, the mice selim grows in a pre formed mode forming a living coffin who surface feels like a velvet cushion. The coffin is then dried to stop to grace. The fun guy then lie dormant. The coffin looks like a star from books and its just as light, but its a completely natural product. That is, its a solid is what special is the Emotional Perception when you touch it. So it feels good. Its warm, soft and light, but also very stable. Yeah, so the coats inside can be almost to me to tool way up to 200 kilos for the barrier. Its placed on a bed of fresh moss to speed up the decomposition process. The moist most comes into contact with the, dried myself in, bringing it back to life. More than 100 people of already being buried in my cellular coffins in the netherlands. Last year, a funeral director john phone test a robot. So 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 dump them into. I dont think People Choose of my celia, im 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 well have 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 ca, skit. It shift thousands of tons of wood, steel, bronze, and copper buried underground cremation isnt much better 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 wouldnt cost it. By contrast with the living coffin, it takes just 2 to 3 years. And at the same time, the mice selling them releases 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 he convinced funeral director york fuser egg from cuba, a live of strong towards with burials desk and warning flows. And sustainability is a really big topic came up. Its 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 todays house as also stand in project, im on the on even if some people arent 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 of beds to land, which seems rather risky. That prompted view of jorge much say a to send us the question all the way from colombia why arent birds electrocuted by power lines. Busy power lines offer birds of the lofty landing spot, but theyve 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. Dont 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. Lets use a single wire to connect a battery with a light bulb. Nothing happens. Electricity doesnt 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, its 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 thats 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, geese, 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 d is 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, well give you a little surprise as a thank you. The just start thats it.
