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, fire supplies. 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 ground both times. 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, what the 2 biology 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 that are on a mission, a numerous potential of millions of green areas that we have in germany and other countries like germany. So we have gotten a lot in mens side walks balconies. Its all spaces where theyre 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 assets towards native plants that are threatened at risk of declining. Already all declining is most of the native plants that cultivated in the oven areas around the board. It could help to slow the decline of biodiversity. 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 supports your fights. So the non native tons, then we only support a small fraction and these tons already managed very well to disperse. So they are not at risk where as many native tons of our at risk in germany around 30 percent of native plants are in danger. Landscape architect jody effect until they go to the x with trees traps and flowers. In her experience, customers dont usually ask for a native partic, subject plans. They just want a hobby plans that are resistant to disease and easy to care for them both. Does she prefer to plot your video . Not to this sean. They are struggling because of course we make our selection space very much on the design, depending on what people want for cindy lloyd though. So 1st we look at what people want. I can then we look at the location though, just because they are all really different. Uh, 5th one of the phones most. Then we choose the right plan, dividers present, for example, that can tolerate shade or the loves. So for electronic along or species that are able to cope with less water, the affinity will also select call. It boils down to a mix of native and non native plants. When people do ask about native plants coordinate is more attractive to exotic are native plants. Guests of all gone to so as of us me, you cant really say is that 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 only on the except that probably makes most sense is having both variance and follicle. So native species supplemented by non native one solution, i can think of different lenders and all that collects 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 . Concepts which is complicated and its 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 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 or no impact at all kind of also cool have and what about wild beast, a comfortable finally. Coincidence depends on how good they are at dealing with the changing floor of course. So there are general lists among wild bees. In, for example, many bumblebees can use a wide variety of plans for food, but there are also many b as in the movies that cannot vary depending on a small number of plans that im using. 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 god and in the emulates nature. But the plans here, primarily native species like meshed out and deals in c, g of want the like. So what does a funny thing, im sure, 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 screwed up. So then we also have fig trees suffice to fight and we harvest the fruits and the one to the highways and flower native plants are primarily for the animals. And so like these wild areas here by the pond to a non flashing and you have the semester present in ties. 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 dragonflies, these, it isnt an extra god and has many advantages. But it has a lot to look at god and is need to be knowledgeable about the plants, english, the inches in c, g, a like the nature of god. But 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. This bill one big sticking point, according to research is 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 unloved. Tons, i love to eat with the native plants or exotic species. Snails loves them old. So do we stand a chance of keeping limits of all gods . Now thats what you call moving at a snails pace. 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. 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 loved 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 garden. The little smells are not the same as 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 pest. Like the spanish slug. How can you combat slugs . Most of methods focus on killing the intruders, but that affects both slugs and snails are like. Household solved 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 fair phosphate 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. Sawdust. Egg shells, sand ash or dry coffee grounds are tough to slither across. Slugs like a damp predators like runner ducks are an especially effective but labor intensive auction. A one a is arent familiar with a sense of sentiment. It keeps them from smelling. Let us when she leave it, once a smug has tasted a plant with chile on it, it will never go back and word gets out this place. This will sprinkle the mixture over the bed and put some on the leaves, some of this toil its non toxic, but im advertising for slimy. Let us these 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 read 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, theyre looking for ways to make the best possible use of low set in agriculture. The water is a precious resource. Really phone a is 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 driven irrigation can reduce water us by 50 percent dangerous cost cycle, or 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. 2 separate sensors at different depths and the ground measure its moisture. When the song gets to dry, the sensor 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 hes developed a fully automatic irrigation over were in a part of the orchard, e that for experimental reasons like we havent irritated at all. Is it due to how scholastic, currently, fortunately, observe, is that the fruit here is not only small, its not the best quality cutting t a p 0 in terms of 1st choice that would cost to grow or tens of thousands of francs per head during the income mass of weight that deal with the over new port or 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 ill provide the cold. Yeah. The, to show you how long a treatment survive without the water. In fact, a tree has some mechanisms that allow it to survive without water. Excuse me, but im a dispute of assorted without water. They stop growing and cant 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 as if we so its the yields the quality of the production that is affected by the lack of water. He fixed the bustle or volume moved to aside from so improves. There is another way to measure entries need for water. Den draw matters. A Research Project by monets colleagues measures the diameter of the tree trunk. During of 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 over night. If a tree doesnt get enough water and cap regenerate and experience is whats 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 wont occur. Its often valves that people forget to close that lead to water waste. We bundled these oh, thats cool. No, 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. 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 fund guy can decompose volcanic materials, including complex life phones, lab coats, rubber gloves, safety glasses, some wood shavings. The phone goes both from the laboratory, mix them together, add water, and weight about so bub 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, 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 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, by studying architecture. He dealt with living building materials. Since my cell, you can be used everywhere. Bearing at this level 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 only. So the more people who are buried this way, the better it is for the or 8 thats fundamentally different to our burial rituals today, the product of auto and just 7 days, the mice selling them grooves in a pre formed mode. Forming a living coffin, whose 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 into psalms is what special is the Emotional Perception when you touch it, it feels good. Its warm, soft and light, but also very stable. Yeah. So the coats inside can be almost to meet his whole way up to 200. 00 kilos for the barrier. Its placed on a bed of fresh moss to speed up the decomposition process of the moist most comes into contact with the dried myself. I am bringing it back to life. More than 100 people have already been 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 ceiling, 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 those 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 was toxic substances. One of the most resource intensive burial methods is the classical christian ceremony with a wooden cost get it shift thousands of tons of wood, steel, bronze, and copper buried underground. The promotion isnt much buses in europe, around 70 percent of people know choose to be true basis. However, this produces home for the admissions and toxic ashes at the cemetery. 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 release has 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 gunning burials from both. Hendricks himself he said to me, convince funeral director york cubic from cuba. The bible stacked on top with burials, desk and warning flowers 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 noise 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 inside that claim on the, on even if some people arent yet ready for more sustainable burial culture, both hendricks and other Funeral Directors expect that soon. Many would choose living coffins as that way of giving Something Back to the the best. Also posit this club life, they help to spread some seeds. They eat insects and keep the numbers and check some even st. Quite nicely on. Say often do that from is off the heights. Power lines are a popular place for flux if the 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 are birds electrocuted by power lines . The power lines offer birds of the lofty landing spot, but theyve chosen a high voltage look out 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 birds because the 2 neighboring points on the table carry very little voltage. Birds can relax and enjoy the view thanks to the principal of of electric circuit. 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 polls. 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 the power lines and the transmission towers can be troublesome for larger birds, like eagles storks, these and even crows. Every year, thousands of birds died 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 cables, the circuit is then complete, and high voltage electricity flows through their body. The. This d appears to have been one of the lucky ones. It hopefully just got a minor shock because the blood is red. Why are they if you have a science question, 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 for this edition of to laura today, the dw sign show.
