from politics to flash from housing to top this is where they are. welcome to the 77 percent. this weekend on g.w. . welcome to the health show on t.w. . here's your host to cast in liquid tat. hello and welcome to in good shape did she know that more people die from air pollution than from smoking. and this is just one problem because this is killing all planning to. exhaust you change of all time even for me is a g.p.

it's a very important topic will there be new pathogens so what will we eat in the future and what about the rising temperatures of the how our bodies in the year 2018 in germany is no more than $1000.00 people were killed at. extremely hot days and lingering he took night for days in a row that's becoming more common in many parts as climate change advances. it's not good for our health in fact heat can kill it's a country and her cheek can become a health risk factor especially if it goes on for a long time by even dr hitz he subjects the body to enormous stress at some point the body gets exhausted after. during a lengthy heatwaves hospital emergency room.

it's good for me to view there are more viruses and bacteria and we have to take that into account we also see cases of flu and i don't usual times of the year so significant changes are indeed underway. extended periods of greater heat can trigger cardiac arrhythmia that has to do with sweating a mechanism whereby the body tries to cool itself sweater evaporates it draws heat out of the body the body cools. but sweat depletes the body of water amino acids you really are and salts otherwise known as electrolytes. we need electrolytes so that we don't get cardiac arrhythmia or feel extremely weak patients notice when say their potassium level is low because they have occasional extra heartbeats well their heart misses a beat have all said that when it gets very hot our blood pressure comply met that

too is a result of the body working to cool itself down. if our body temperature rises above $37.00 degrees celsius our blood vessels become dilated which expands their surface area. with veins stand out helping to cool the blood but vessel dilation means the pressure in the vessels declines that can be risky for patients who already take drugs to lower their blood pressure it can drop so low they faint that's what happened to him on an exceptionally hot day after i felt strange all of a sudden here i felt really awful so i went inside and at that moment everything went black in front of my eyes and 3 or. 400 doctor the case was clear. often medication needs to be

adjusted to cope with long hot spells. one come. on can reduce the dosage or stop taking a certain drugs varies and depends on the underlying disease some patients don't just have high blood pressure but also have heart disease or kidney disease. at charity university hospital in berlin climate change has become a topic of research one hypothesis is that a warming environment jeopardizes the healing of wounds for example after an operation there. are lots of bacteria on our skin and in our gut we're seeing more and more wounds that get infected one possible explanation for that is as these bacteria change during lengthy hot spells. pathogens lurking in hospitals also budget when it's warm.

inside your follow up studies confirm that there is a link between warmer weather especially for lengthy periods and the incidence of infected wounds that could constitute a risk to patients. and conditioning could help according to dr one ski domenica he studies public health on the environment and says health care facilities across germany need to adapt to rising temperatures and lengthy heat waves. to some hospitals in france for example have wanted a conditioned room for patients on every floor says that's certainly something worth considering. climate change is said to become a major challenge for all of us and for our health care providers. to see us when it's hot outside bringing southern lifestyle to the north this could be one way in dealing with. a change but honestly this is

not the solution what the solution could be this is what i'm going to talk about your heartland today from look this is the german alliance for climate change and to help. the climate crisis as a whole so the health crisis but with a healthy lifestyle we can protect our well being and at the same time. we here at the labyrinth judy museum in berlin currently an exhibition about climate change and this is our topic we'll talk about because you're a co-founder of an alliance called luke which means smart so what's about so rigid term in climate change and health and we found it. years ago

and we're in interdisciplinary. health professionals doctors nurses and so our main goal is to put health into center of climate change discussions so weiss is so important because everybody's talking about the health of our planet why do we have to focus on health 2 because as humans we are connected parts to our direct environment people can only exist on a healthy plain old and climate change will influence of course nature around us but also human health and whatever your facts of climate change has an abaya direct effect are fixed imo if you have heat waves or extreme weather when thawed a direct effect of these on our human health and indirect effect after example if we have. warmer temperatures and higher concentrations of c o 2 trees are producing more paul for example so people who have a lot gees will suffer more from these conditions and even some different

diseases coming out of this climate change so they're not new diseases coming up but diseases we normally know for a deceleration reaches of our world will come to us as well so for example talking about. insects who transmitted diseases they will come to our regions as well what about different parts of the world where it's already hot and warm if you have a look at the areas around equator in 2050 there will be areas where humans won't be able to live anymore and just because the heat is so extreme that we conduct it physically these people living around these areas they will have to look for new areas to live so people will migrate and they will also come to you obviously so you are fighting against climate change in your lines what did you achieve so far. for example this year the german doctor said we will talk about climate change and health as a main topic so it's a really big achievement because the years before they never really talked about it

and also our health minister he just claimed saving to climate means saving our health so he's starting to talk about it morris world and we also have local groups who act on a local level they're talking with directors from clinics but also from universities to bring up this topic more and more so there's some political pressure building up actually but what can i do what can we all do so of course we can change our way of living and it's definitely one thing we need to do but there are 2 other things i think that are even more important the 1st thing is that we have to talk with our friends and family about a topic because only by talking about it we will find solutions that have a broad acceptance and i was society and as well we have to be get politically engaged so that we can demand for the politicians for the change really to reduce emissions so that for example cities built cycling pathways that the cost we have

to pay for products really represents a cost that is put onto nature also and of course that some of that can teens for more the chariot wheels and then of course we have to change our way of living also eating less meat taking the bike more often so our lives will change actually in everybody's just talking about traffic about electric cars about taking the bikes but you said the vegetarian diet might be important as well because we have to talk about livestock and the industrialized meat production we think that more than 50 percent of all the pollution gases are coming from life stock so maybe it's time to turn to vegetarian diets. huge pig and cattle farms and industrial scale meat production consume a lot. of energy and have a major impact on our environment and climate so what effect does our diet have on our planet and health. these questions with the focus of

a recent study by climate scientists. and an international team of research is. the 1st time ever we do a scientific assessment linking sustainability of food. which is. i have. significant. the study shows very clearly the repercussions of. the production of food takes up 40 percent of the earth's surface and 70 percent of the world's freshwater and it's responsible for 30 percent of greenhouse gases. depleted of nutrients requires more fertilizer and the global appetite for meat means that more and more rain forest is being cleared to make way for cattle grazing land.

dietary recommendations. 40 grams of meat per day around 500 grams of fruits and vegetables. 250 grams of dairy products. much of the world this would entail a substantial change in how we eat. this diet would be a major benefit to our health. health of the planet. my call here is to get the food agenda right into the climate negotiations and right into all the climate action to understand that it's not enough to just decarbonize the world's energy system we need to decarbonize to get sustainable food systems as well. knows a change of mindset is what's needed after all it's consumer habits that shape demand. each one of us has to decide what we do for our health and the future of our planet. so how much meat do you eat i actually have been eating meat

for by new years already so you return yeah ok so the vegetarian diet had died you would recommend for say everybody here definitely i'd least i would recommend to reduce the consumption of meat because it's way healthier as well for of course for our planet and as well for human health but it's very very difficult to change habits especially the eating habits so you've got any tips how to change it it's not about everything or nothing i think reducing the meat consumption step by step with key to how to do with this problem so of course they're going to imitation products and you can use them and also there's a health fire to it is the recommended by the lancet descent of joe we've been talking about and they're. recommending it died which includes meat and fish but only in or around so if somebody wants to go plan based on his or her diet would

you recommend using. turnitin is like meat in the beginning i think it can make things easier but still often very processed and contain a lot of salt so in the end you should aim for eating more well until it's been for example so products like tofu or tempe and also nuts and see. or if you want to top off your protein you can even eat insects i mean many people around the world eating insects on a regular basis they are very nutritious they're tasty they're high in protein and they harm our environment much less then for instance carlos. is this the food of the future it could be since 2018 the european union allows insects to be processed into food and supermarket chains are already offering

products made of insect flour or even entire larvae like buffalo and meal worms in many parts of the world insects have been consumed for millennia so the insects are even considered delicacies. but in europe they're a relatively new colony or a concept the e.u. has strict hygiene regulations for insect farming species raised for food include grasshoppers and crickets meal worms and buffalo worms the worms are fed a special powder after just 2 weeks these lovey are ready to be harvested they're not put on a diet to empty their bowels that's where most bacteria would be found. then they're washed and frozen. as a final hygienic measure before they're marketed the worms are heated to at least 85 degrees celsius. in view of the rapidly rising world

population the united nations and many experts have long viewed insects as an important food for the future it could be the only feasible way of meeting our protein needs. another advantage of insect farming is sustainability insects grow quickly and don't need much feed and raising them doesn't require much energy or other resources. producing one kilogram of beef takes around 15000 liters of water a kilo of insect meat requires just 4000 liters cattle consumer around 8 kilograms of feet per kilo of meat insects just 2 kilos. better bull insect products include different kinds of pastor burgers muesli energy bars and insect snacks like chips there's a huge variety with a large range of tastes but for those of us who aren't used to eating insects what

are they like. what good it's ok if it tastes like whole grain. this burger chain in germany has insect patterns on the menu some of the guests are intrigued and willing to give it a try. and in something different people eat this in lots of countries it's just a matter of attitude. so why not be daring and give insects a try you never know they might taste better than you think. so what about you have you ever eaten some insects. career. out of the tasty i don't have to try to and try to know it's ok i think you probably have to get used to. it in the future but there were maybe it's a cultural thing so i'm very interested in you did you ever eat insects and how did

they taste to you why don't you just write me an e-mail with your experiences and if you're already at your computer screen e-mail with your questions to. on an upcoming show we'll be talking about can the base for many it's not just a recreational drug but a healing one how does marijuana affect i'm what are the risks sending your questions about not in good shape at d w dot com just right in the subject line we look forward to hearing from you. so if we all would start eating insects now with the stop climate change unfortunately it's not only about our nutrition it's about how we generate power for example but it will definitely always help a little bit and insects are really efficient in converting fruit into mass producing one kilogram of insects you only need to give a gram so. and for example whereas for producing one kilogram of. beef you

need. to slow down climate change a lot because you're far away from reaching the. parity agreements and also clement's that. tipping points from when we're talking about climate change we're also talking about a tipping balance we're going to reach them earlier than expected for example one tipping point. it's going to molt. parading and there is a climate as well or greenhouse gas and so to be accelerated. and this is not reversible once it's not reversible and it will make other tipping points for some melting of. ice caps to. accelerate as well so what are you doing personally so i'm a vegetarian that i'm also trying to buy more secondhand clothes also to buy 2nd hand gadgets. bicycle more often and obviously i'm engaged as

a climate activist arrived here but i think there are some opportunities involved as well to stop climate change in mitigation measures and it's really important to talk about that as well because climate change like to stop climate change will benefit our health for example if we take a bicycle more often we're physical effort. and a lot of other diseases we call the non-communicable diseases they are caused by our lifestyle so eating too much sugar to ferry not moving enough and by living a more active lifestyle for example and reducing the consumption of meat get healthier as well so we can save yourself and by the way we are saving the planet to. which we have discussed this is the world's population experts believe that in the year 2050 there will be $10000000000.00 people living on this planet which is $2000000000.00 more than today but how many people can we feed. by the

year 2050 will we be able to feed the global population with organic farming or is that just a pipe dream. scientists in christian charter have published an initial study commissioned by the un food and agriculture organization. the results don't make for good reading. so. we would need a lot more land and that would mean tremendous changes if we were to produce like we do. today it's basically impossible and. the study concludes that if we continue as we have so far we were not be able to reliably feed humanity either with organic or with conventional farming the researches took a number of factors into account for instance eating habits which around the globe have come to resemble the prevailing western lifestyle. more and more people want

to eat meat and dairy products. that means a drastic rise in the need for animal feed to produce all that along with the environmental damage that would result in those. that present global meat consumption is $320000000.00 tonnes a year it's predicted to rise by half as much again by 2050 demand for eggs and milk will also go up dramatically. raises the question of where they'll come from so we don't have any extra land that we could use without losing a huge amount of forest grasslands will be associated or full impact on biodiversity and so on. so how to secure the global food supply in the long term charter says not simply by producing more land for travelers reporter saw

agricultural production has already been highly optimized in most western countries and many other countries. that means the natural potential for producing food on a given amount of farmland has already been reached. and we have to think about changing things and the entire nutritional system to address this problem more effectively he runs. the scientists have taken a closer look at global food consumption and come up with 2 strategies. it's absurd to expect the increased yield on long to solve the problem of world food security while a 3rd to one half of all food is being thrown away. so the 1st strategy calls for less food waste the 2nd is about raising animals for meat. 2 the scientists call this strategy feat no food the idea here is that animals should not be fed anything that people could eat when we feed plants to animals and then eat

their meat many valuable calories are lost if we ate the saw corn and wheat that's currently used as fodder we'd get around 20 percent more calories. than for that reason animals should be fed exclusively on grass and waste products in keeping with traditional farming methods. doing without meat altogether is not the solution say the study's office 2 thirds of the world's agricultural land is passed to land it's too barren or uneven for cultivation it's best suited to growing grass and not much more in the long term used as grassland for human nutrition such as cows sheep and goats are an important element in turning grass into food for humans . if you meant food is then also rich in protein. the study finds that its resource needs to be used to secure

a food for the world but it does recommend lowering meat consumption considerably. your business can flourish we don't have to stop eating meat if we reduce our meat consumption by half that's already drastic but doable i'd say it's not about implementing extremes it's about moving in the right direction and through. all the calculations point to a drastic cut in our meat consumption it's not really necessary. we don't really have a choice and we have to achieve this somehow if we want to feed the world in a way that makes sense on this planet and if we don't do that then we'll have no chance anyway. commercial. the recommendations put forward by the 2 scientists are clear. the difficult part will be implementing them . that's it for today and today i won't commute by car

i would run so see when it's rick and until then let's all try to stay in good shape.
