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 certain insects are even considered delicacies. but in europe 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. and buffalo worms the worms are fed a special powder after just 2 weeks these lovey are ready to be harvested then put on a diet to empty their powells that's where most bacteria would be found. then their 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 consume around 8 kilograms of feet per kilo of meat insects just 2 kilos. edible 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 to behave like whole grain. this burger chain in germany has insect patties on the menu some of the guests are intrigued and willing to give it a try thank you so. much and in something different and people eat this in lots of countries it's just a matter of attitude make up something 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 to try them out of korea. and out of the tasty i don't have to try to. try to know it's ok i think you probably have to get used to. it in a future but 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 email with your experiences and if you're already at your computer screen for me e-mail with your questions to. your weekly show on w covers many aspects of health care we look at what's new in medical treatment. we talk about these topics in depth. and give you the chance to pose your own questions so do get in touch. 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 you could say for producing one kilogram of insects you only need to have a gram so. and for example where for producing one kilogram of. beef you

need 8 kilograms of what else must have to slow down climate change a lot because you're far away from reaching the climate. and also climate scientists that tipping points from when we're talking about climate change we're also talking about a tipping balance we're going to reach earlier than expected for example one tipping point just for us it's going to melt anything. and climate gas as well or greenhouse gas and so on process will be accelerated. it and this is not reversible. man it will make other tipping points for some melting of the glaciers and ice caps. to accelerate as well so what are you doing personally so i'm a vegetarian grower talked about that i'm also trying to buy more secondhand clothes also to buy 2nd hand gadgets. bicycle more often and obviously

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 as well 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 their cost by our lifestyle so eating too much sugar are 2 fairly now moving in the earth and by living a more active lifestyle for example and reducing the consumption of meat we'll get healthier as well so we can save yourself and by the way we are trying to. there's one more thing which we haven't discussed this is the world's population experts believe that in the year 2050 there will be 10000000000 people living on this planet which is 2000000000 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. relations are showing that we would need a lot more land and that would mean tremendous changes if we were to produce like we. today it's basically impossible and. the study concludes that if we continue as we have so far we will 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 for us to. at 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 really losing a huge amount of forest grasslands would 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. we have to think about changing things and the entire nutritional system to address this problem more effectively. the scientists have taken a closer look at global food consumption and come up with 2 strategies as up to it it's absurd to expect 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. the scientists call this strategy feed 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 saudi 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 all fits 2 thirds of the world's agricultural land is pasture land it's too barren or uneven for cultivation it's best suited to growing grass and not much more on these. grassland for human nutrition. such as cows sheep and goats are an important element in turning grass and the food for humans. sure meant a lot of people were just also rich protein. the study finds that it's 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 to go through. all the calculations point to a drastic cut meat consumption is that 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. conditionals. the recommendations put forward by the 2 scientists are clear. the difficult part will be implementing and . that's it for today and today i won't commute by car

i will run. and until then let's all try to stay in good shape.
