the police and the we are here is actually on fire made for mines in the the ah, me, if there is one color that's the embodiment of today's zeitgeist. it is green. green stands for lush, chemical, free grasslands, for emissions, free mobility, and for a future in a healthy climate. it is no wonder sustainability has become a top issue for companies. but are these projects profitable?

and all the actually as green as the peer? the green economy can work. that's our topic this week on mate. when it comes to the things that are essential to us pretty much, nothing goes without water and looking at the planet. there's plenty of it just not the kind we can years right away. most of it is salt water and less than one percent is drinkable d, w, as christian carla. on the tradition of dissemination, and whether a berlin startup could have falls a global water crisis. in 2015, a series of drought started to dry up as damp the source of almost half of the water available to cape town. south africa. in this satellite time lapse, you can literally see the stores water decreased month by month in 2018. the city was approaching day 0000 is fast approaching shorthand for the day. the taps run dry and people would have to q

to get water rations came down was the 1st major city to risk running out of water. but it's not going to be the last jakarta, london, beijing, tokyo could all face their own de 0 in the coming decade. the most possible order, at least through the form of the year, are experiencing some will to stress those or the gap between demand and supply. your water is netting. how can that be? our blue planet is washed with water. more than 1000000000 trillion leaders to be precise. the problem is that 97 percent of the earth's water is faulty and most of the fresh water is frozen in ice cost. less than one percent of the earth water is drinkable. that makes one solution, especially promising elevation you sell a nation, these hello nation. the sell

a nation seems like a pretty straightforward solution. you take that undrinkable, salt water, remove the salt, and end up with an unlimited supply of fresh water. so why are we not building more desalination plan? b, l, a nation is a natural process, has been known for millennia. as the ancient greek philosopher, aristotle noted the sun turns ocean water into vapor, which then condenses again and falls back as rain. compatriots took note sailors boiled sea water on long journeys. romans used clay filters to trap salt. these are still the 2 basic principles used today. thermal declination uses heat falls, boiling point is a lot higher than water. so if you boil salt water,

only fresh water will evaporate, leaving all the salt behind membrane desalination use as pressure. salt water, sheer colored in red for clarity is present through a membrane that is only partially permeable. fresh water can pass through here colored in blue, but the salt is trapped on the other side. this technology didn't improve much until the 19th century when industrialization and population growth encouraged more research. population growth is the main driver far, was skipped lunch. there is an environmental scientist with more than 30 years experience in water management, shifted instance, middle east and north africa agent. that region has the population of about 5 percent of the word population,

but just as one percent of the global water resources. and soon, another factor could make dissemination even more crucial global warming the as the climate war, more water will evaporate. and as aristotle noticed more vapor equals more clouds people's more rain. but that rain won't call evenly map shows how precipitation will change as the climate heat up. regions in purple will get more rain, those and orange less. now compared with this other map, please read does indicate areas that are already experiencing water scarcity today . dry areas like calla fornia in the middle east will have even less rainfall. other countries like india, will have more rain in the monsoon season, but less and the dry season when people need it most. this will make desalination

even more popular. and this rudy are starting to explode, i'd say since the late eighty's and ninety's, but especially in the last 20 years you've seen a big celebration. edward jones is a p d candidate who has put together a state of the art outlet on the status of desalination. nowadays we have around 16000 deceleration plans which are producing more or less 100000000 need to scoot but take a closer look at this map. if you look at how much the selling needed water we produce on the school, currently 71 percent is produced in high income country. that's because desalination is very costly. the boiling billions of leaders of water takes a lot of energy in the middle east. the availability of oil and especially fossil fuels makes the thermal purchase is cheaper than for other types. it could be,

i think, $25.00 or 30 times more expensive. but that energy doesn't have to come from fossil fuels. the 3rd up in berlin had the sustainable alternative. my name is kim, i'm the co founder and ceo of the company boy light. so i moved from west germany to berlin. let me just see what you will also doing, solving your water, if you like. yes please. so the water come basically from the whole site to the system. and after that is gone through the booster farm, with 14 by the water is fresh to the membrane. it's need to make water re energy, green energy. that's the key to the company's success. this is one of their plans

in kenya with the solar panel keep the cost of water and low in villages like this, where electricity is not available. ah, ah, in the water for free. we liquidity from the solar wind for free, so we can now produce $0.10. this price is actually competitive to clean water from the river, from the bowl. but there's another problem. what do you do with this water that's left behind? so we forced all of this, so look out of the water to produce fresh water. but now this is still contained within our substance, but it's just a smaller volume. so it's most ot ah, water is called brine. and the global that when we produce more brine,

then we produce a pipe with this coming out of the discipline, discharging the cycle and move it in as it flows out in things because it's in the temperature and also the, the oxygen available. and this is what's causing actually the organisms more damage, just the lack of oxygen that basically suffocates a ah, bryan can also contain chemical harmful to see life needs to be a better plan for the industry of dealing with this broad. we're producing more waste with no clamps. what this waste could become a resource, tomatoes, seaweed, and certain fish can tolerate high salinity. morial light uses brian to cultivate them in tubs like this is also the opportunity for so recovery and symmetric

recovery. at the moment, the technology is auto vailable, fire brian management, but those are on a very small scale. the challenge is that we can transform those small scale technologies into a large scale operations. desalination is not a magic formula. the process must become more efficient before low income countries can afford it. nation plants must convert from fossil fuels to renewable. energy is to limit emissions. and the whole industry needs to come up with a plan to deal with this. brian, what facilities like this already a lifeline for many communities is very important to realize that these nations in the state we really need to work towards solving the challenges of the selection process, which will not again happen overnight. but i could see that daily,

that at the same time, getting the video also to harvest the potential for the sending it to the watcher or town is doing a lot better and the dam is full. the city was rushing to build desalination plants to avoid daisy row, but dissolution wasn't desalination or any other technology. no one should be showering more than twice a week. and the topic flush was only when you really need to flush these made it to base it in trying to use and have to save water as if your life depends on people. water wise, they radically changed their water use. we use it consciously and mindfully trying to save a valued water for the essential and the replacement substance that it is. and

that's how it should be. by the way, you can watch videos like the one you just saw on our youtube channel planet 8, which also has lots of other content on sustainability. now we are a business magazine and we do have a liking for numbers and bees. they are really alarming around 820000000 people are suffering from hunger around the world. and at the same time, about $1300000000.00 tons of food go unused every year. due to the lack of proper logistics or food gets wasted. because pears and peaches don't look as fresh as we would like. increasing shelf life could improve things. and here's an idea for how to achieve that fruit and vegetables rotting in feels or during transportation to consumers. according to the un food and agricultural organization or f, a o,

some 14 percent of food is lost after harvesting. and before it reaches the market retailer. if you go to a particular country or particular, you're likely to see varying levels of food losses. and these, depending on the situation, would go up even to 50 percent. if you're talking about, let's say fruits individuals, for example, if the firm does not find the market for that particular food product in a timely basis. now this is huge amount of food. and if you, you convert it into monetary quantities, this is a lot and if you read it as well into the loss to the environment or the environmental impact that is also huge. when that happens, water, pesticides, and resources used for transportation or all waste as some 7 percent of global greenhouse gas emissions can be traced back to food loss and

waste. the chief causes include problems, the transportation and refrigeration. the power from harvest. the kitchen table is a race against time. a california based company appeal sciences might be able to help founder james rogers and his team have developed a liquid that could extend the shelf life of fruits and vegetables. appeal is a little exactly like it sounds peel and we apply to the surface of fresh produce. we can't see it. you can't. you can't do it. but it slows down the factors because the fruit to age it helps even without refrigeration appeal as a liquid coating that dries into a kind of edible skin. the coding helps the produce last up to 4 times as long. that 5 time time to transport the produce to storage and to eat it before it spoils

. appeal is based on liquids and other natural compounds found in fruits and vegetables. there extracted and blended into a taylor made solution by combining them in the right ratios. when they dry a dry into an arrangement that allows us to control the factors that cause fruit to age, which are basically water going out and oxygen going. yeah. so same materials were just teaching them a new trick by finding the right formula to apply to different kinds of praise, in order to give them the same kind of protection that you'd have on women. on a cucumber or on a dutch wholesaler nature's prize cell, some 120000 tons of fruits and vegetables a year. they import from 59 countries,

especially latin america in rotterdam, the imported produce continues to ripen before it's sorted, packed, and shipped to the retailer. sportage a waste of the common problem in the industry. but the company hopes to minimize these losses in the future. so through the way they actually bought it and they don't use it and that costs money. so in the chain, if we don't throw it away, you don't spend that money wrongly with a be a we can reduce weight, was 50 percent at the retail level. through that used to land in the trash can now be sold every day. nature's pride treats 6 tons of cars with appeal before sending them to supermarket shelves across europe. the main customers are in scandinavia, germany, and the netherlands. natures prizes the 1st company in europe to use appeal are planning to start treating other kinds of fruits and vegetables. soon i

started coming by air by using a view, we might give them the possibility to go by boat. and that is, of course, the same reasons i said, so there's lots of weapons unit so far the new technology is mainly being used by large companies. smaller ones can't afford it. but appeal says it's planning to change that with a new business model in which retail chains and supermarkets pay smaller producers and farmers to install the necessary set up in return they receive longer lasting produce farmers in places that haven't had access to national international markets could also benefit and so the opportunity is to be able to use appeal to reduce the transport cation cost and increase the quality. so it's not a, it's a way. ready for a some, a small producer to grow something that's intrinsically valuable to collect. some of that about extending the shelf life of projects will help. but it won't end the

problem of food. lawson waste for the transportation and refrigeration systems will also need to be improved and expanded and consumers will have to stop throwing food away and start only buying what they'll actually ease. but if we buy more food then we can actually eat it doesn't take long until flies and other creatures starts warming. the football most people don't feel particularly drawn to insects, which could be one of the reasons why pesticides sales here in germany have been at a steady high. while recent studies show the flying insects and german nature reserve have declined by more than 75 percent in the last 27 years with industrial farming being the most likely cause what some call in sexual get a has been starting to change people's minds. and the business model of the b one pesticide maker is off nicely. well,

because i put warnings on my product. my banker skeptical me all. yes, so i worry about my future. fixed can be for comments. things like his father before him. humpty, tree square house makes household insecticides the family run. some had been operating in the same way for decades until these 2 artists called its purpose into question me the make me think the com and look at insect wreck house in the artist joint forces. they organized and event to raise awareness for insect that preservation.

in the village, residents ended up collecting 902 flies, one lucky specimen. evil one, a prize. the fly. erica was treated to an all expenses paid spot weekend with the owners flight included. the dental child will be in the death we've been out in about with erica, not one person has given us funny looks or called us a bit loopy. don't. because me the event prompted hands feet tricks like how to put his company's future on the line. he's invested around 2000000 year rates in the conservation of insects and other small creatures . the project also includes setting up green roofs to compensate for the animals. his products have killed the brief of his headquarters. so become a home for insects. me might have put my product is

killing 2nd mission, but i don't see a contradiction in making insecticides while at the same time helping insects from keller to save. you really always this just a marketing ploy because these days, products that can boast, environmentally friendly credentials tend to sell better. me me get. this isn't about marketing. i want to see the market reduced as seen in the warnings on my product, called one product of your product has a big label about the dangers involved. voice for him, calcium for designer hands. decreased. house is now introduced alternatives that he feels more comfortable with such a life trap for fruit flies. the insect is attracted to the spite of vinegar, and then trapped in the cylinder to escape on harmed. kinda from

isn't really going for this product because it's not obvious why you should save fruit flies. it company has seen turnover drops by 25 percent. his profit to fall and even more. so wouldn't simply selling the phone be the logical business, smooth color, metal filling would mean surrender and giving up responsibility. it would only benefit my rivals who would carry on with insect, decided by the mom in the car, staying in business, i have the leverage to generate awareness and show that this transformation is possible. so again, you have an unfair sagnasti to tons on that. so on the house in kansas demonstrates his commitment to that message as he plows up the company comp, how to create a new inspector this but he can't say for sure when his own metamorphosis will be complete. i got to admit, i did it

a couple of weeks ago, took my 1st pandemic holiday flight, along with maybe 20 others on the plane even without the pandemic deviation. business is facing enormous challenges with sustainable flying. being high on the list, our reporter dan, her shalt took a look at a company that's taking a step in the right direction. almost 7000 leaders of asian fuel have been pumped into the tanks of his cargo plane. and they're not even half full yet. the flight from franklin to shanghai, china is a long one, but this flight is something special. the congo subsidiary of germany's largest airline. lufthansa is operating this as a carbon neutral flight using sustainable ation fuel and easily. it's basically a fuel based on the plant oil. so the fuel and that only the carbon dioxide that previously absorbed it doesn't admit any extra seal to prevent an aircraft operated

with sustainable ation fuel. it miss up to 80 percent less greenhouse gases. but the climate friendly fuel costs between $3.00 and $6.00 times more than regular jet fuel. still some freight customers want to improve their carbon footprint and are willing to foot the bill, like which is the company devi shanker, which chartered this flight. the climate neutral biofuel is produced at this refinery in poor val finland an hour's drive from helsinki for more than 10 years. shami ya here. i name has been working on replacing the kerosene in evasion fuel with sustainable raw materials. the production process is using waste and received your types of oils and fats us raw material as used cooking, los alamos, for the future we are exploring new role materials such as municipal solid waste. $100000.00 tons of biofuel are produced here every year. that's

a drop in the bucket compared to the 300000000 metric tons that the world's airline operators consume annually. y'all, we are in and says that a breakthrough in climate for the aviation fuels will require government action. what we need is it's what governments do to create the market and either create the requirements for, for industry to become more sustainable. other major carriers such as japan's a, n a l. friends, kale, m and american airlines have also started purchasing sustainable asian fuel for the airlines touting their green credentials is proving to be a good marketing tool to win over passengers and freight companies. when i sell that bio fuel will soon be more than just a marketing tool, but a real alternative for the aviation sector. that's our show. thanks for watching and see the
