More coming up the hello and welcome to tomorrow. Today the science show on dw, the emitter like this is full of activity. Flowers blossoming, fire supplies flying and please humming. Scientists have proven that foam 9 meadows serve as a source of food. A habitat for pollinators act as coughing sinks and how 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. A lot to biologist 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 our concept is that we want to harness the numerous potential of the millions of green areas that we have in germany and other countries like germany. So we have gotten a lot mens side walks balconies. Its all spaces where there People Living intimately with the spaces where people are interested in planting things and these spaces. And what we want to do is re direct those efforts towards native plants that are threatened at risk of declining or ready. 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 the focus on native plants so important . Currently recount 13000 non native plants 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 gemini, around 30 percent of native plants are in danger. Landscape architect jody effect until he goes to ex, with trees trump some flow in his experience. Customers dont usually ask for native partic, subject plans. They just want hottie plans that are resistant to disease and easy to care for them. Both does she prefer to plot . Youre viewing that to this sean. They are struggling because of course we make our selection space very much on the design, depending on what people want the most. Indeed, all right though, so 1st we look at what people want. I can then we look at the location file just because they are all really different. Its one of 2 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 infinity. Well 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 plans that will support in 6 and thats 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. Our native plan, the guests have also gone this up as of us video, but i cant really say is that what we see here is that insects like going to non native plants will bundle to flaunting. Because sometimes these plans filled the gap when native plants are taking a break from sun. Mm. No problem. So i need one last i close up. 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 collects the x and the lights. Solution nitro 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 insect concepts, issues is complicated and its not a problem with a new species up here is the question is, was how they fit into an existing eco system, please pool. And that is very difficult to predict. The advance one cause is 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 control . Finally, put the not depends on how good they are dealing with changing floor of course. So there are generalized among wild bees in 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 and when those plans disappear. So to the bees collect dorski is also a biologist. And he to 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 of the plans here, primarily native species like english to how to and deal with the on c g of want the was like so what does your plans and how much the non native plants we have here are mainly crops plans. For example, we have 6, you one pepper most pins, thats which can be used as a spices and because thats for then we also have fig trees. Suffice prof. I and we harvest the fruits on to t. Jaime. Some flower native plants are primarily for the animals. So like these wild areas here by the pond to a non flashing you have the best present in ties. But of course, as i mentioned, there are also native plants that we use, like ment, myself to you means to the mix of native and non native plants seems to work well for many animals like these dragonflies. Bs visit 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. But does it lift up to the idea of a gun that supports native plants and ecosystems . I think the best racial is probably to have between 10 to 20 percent non native 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 these basics. Theyre still one big sticking point. According to research is peoples perception of what constitutes a beautiful god, needs to change or it 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 online ponds. I love to eat with a native plants or exotic species. Snails loved the mole. So do we stand a chance of keeping them most of all gardens . Now thats what you call moving at a snails pace. Us now this big travels at 0. 003 kilometers per hour. Thats just 3 meters an hour. And its carrying quite a load to 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 and 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 garden. The little smells are not the same or those with a 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, sales without shelves are considered garden pest. Like the spanish slug. How can you combat slugs . Most of methods focus on killing the intruders, but that effects both slugs and snails are like. Household solved 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 eric 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 big shells, sand ash or dry coffee ground or tough to slither across. Slugs like a damp predators like runner 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 scent of citizen. It keeps them from smelling. Let us when she leaves it. And once a smug has tasted a plant with chile on it, it will never go back and word gets out. Theres political sprinkles and mixture over the bed between some on the leave, 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 corrupt, say new spots and the long term red ground also poses an existential 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, theyre looking for ways to make the best possible use of bullshit in agriculture. The water is a Precious Resource for the phone, 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 plus 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. Both sides reminds me of an australian publication which demonstrated that drip irrigation can reduce water us by 50 percent to discuss cycle and 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. 2 separate sensors at different depths and the ground measure its moisture. When the phone 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 hes developed a fully automatic irrigation system. It prevents waste and guarantees high yields. Just call the we are in a part of the mortuary 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 guntee producer in terms of 1st choice that would cost to grow or tens of thousands of francs per head during the income moskowitz at that deal doors were new, port of the project 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 stopped, 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 are about to move to aside from so improves, there is another way to measure entries need for water. Den draw matters 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 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 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 the clothes 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. Some guy can decompose volcanic materials, including complex life phones, lab coat, rubber gloves, safety glasses, some wood, shavings. Im 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 and david at grow and gratitude. Burke would be fans of my mushroom. My celia, im coughing the stage, but its an invention for folks who think about the generations to come on new after their dad want to be one with nature and it rich. The soil is complex to not contaminated a human compost. Is that a disrespectful or pretend 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 for you at the end of this level, lay my celia and 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 phone guy then lied to him, and 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. 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 and way up to 200. 00 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 my cell in bringing it back to lice. More than 100 people have 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 myself and based versions cost 1500 year is cheaper than conventional coffins that they need to the main to i dont the things 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 each year, 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 bases. 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 release is 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 convinced funeral director york few vague from que a live of strong torch with burials desk and warning. I have always on sustainability as a really big topic came up. Its also one that seen a huge boost in recent years. And 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 inside, cuz i want to see on even if some people arent yet ready for most 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 uh, the best uh, also posit this uh, club life. They help to spread san seeds. They eat insects and keep the numbers in check. Some even seen quite nicely and so often do that from as of the heights, power lines are a popular place for flux of 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 . 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 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 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 w
