it's coming up next we have a special program on where the base can be produced in a way that is actually good for the environment. the ground for that. if you can, i my new for this weekend and i'll be back over top of the hour with international headlines in the meantime. thanks so much for watching. dw the vacation as an applicant. do they have good weather? i, when i told me that they don't have violence, can we go sailing colson tissue today? because when they go to that, we set up for, you know, medical people, stuff was work hard. one, the tenants. so i so not because the

secret slide discovered new adventures in 360 degrees and explore fascinating. both heritage dw world heritage $360.00 now the there's something about the birthday is it. this is maybe the crackle just looking at one almost feel safe. if only forgetting about their impact was as easy as the lights, but producing food and it's nearly a 3rd of all greenhouse gases and all food. these parties are the worst offenders. some cleaning can do things differently. we're going to be talking about rotational grazing, rotational grazing, rotational, raising the rotational addresses and produce b. so it's actually good to the environment. even carbon neutral because these same cows can also improve this whole well and helps walk c o 2 in the ground. other

state has completely bush, either way, deep as a massive problem and to slow climate change, we have to fix it. is the only solution to or is there another way to eat peace without people have been domestic heating, animals for 10000 years was became dogs, wild, goats and sheep retained an or ox became cattle. today there formed around the world with the u. s. and brazil, producing the most, it's a $400000000000.00 industry, even if you're like me and eat no meat at all. and i just harriet, beef production still affects you because it's responsible for 4300000000 metric tons of c o 2 every year. that's almost as much as the entire united states and fixing this isn't as simple as everyone going beacons that are these to realities, right? and we need to recognize a couple ronko is a plant scientist and i p c. c officer from colombia,

focusing on making livestock more sustainable. their 1st one is cell and developed countries where people may choose what they eat. there are at least i know that reality. and for developing countries, where people are struggling for nutrients, animal protein to make a huge difference and beating up our beef production can help. but what's the best way? i've heard for very simply speaking, there are 2 ways of raising cattle. one is grasp bed farms like this one in northern germany. run by hi colquitt for dental. if you make this more, i guess what i can discuss and some of the next inviting will be really easy. then the next class that's really fixed and vans it to before that i can is quite a bit annoyed. this is a small operation right now. there are 50 animals here. eat in the spring. that's the phone. it doesn't cut it all season yadi. here it's fine, i've got dividends. the most of i do isn't. yeah. on the highest and so called spa, this could be some of the fact that i'm lucky to flash the room around

a $160.00 hector and have a warm bar and for the winter raising cattle. look similar to this in many places in the world. and then there are a few thoughts that can help thousands or tens of thousands of animals. they live in a confined area and eat mostly grain instead of grass as to which is better, grasp it or feed lot, even actually not that simple. that's compare sustainability using these categories . we'll start with what goes in food progress could, cattle doesn't travel far because the, the combination of grass and clover which contains more protein during the summer. so this is all harvested and turned into that for them to eat over the winter. so grass fed beef avoids the emissions and chemical run, also producing grain. it also wins on the water grasp and cattle drink from lakes or ground water. not so for feed lots the cows drink water and showed her the crops going to their feet. there is a downside to grass, the cows update more than then green,

and what goes in also comes out wherever cows are, all these cows are basically constantly burping and farting which generates a lot of methane. essentially, the bigger they are, the more methane they make. methane is indivisible, so best detected by satellite. it's way more potent than c o 2 on a diet of grass, animals go slower, so expel more methane than greenfield caps. surprises when for the feed. lots there . that would also comes out as manure in your, in lots of it, in addition to methane, it releases nitrous oxide and other potent greenhouse gas in the summer. the minority composes in the field and pollution levels are low during winter. the minorities handled similarly to a feed lot, like also technical there. it all comes out here and then it shuttled over there where it's eventually turn into liquid and sprayed on fields. except on a feedlot manure is stored in large pools, releasing more methane and solid storage. and the more that there is,

and the longer it's stored, the more it releases. another big difference is what it contains. on feed lots antibiotics we use to keep animals healthy and stimulate growth. they end up in those are newer pools and can leak into our water supply. antibiotic resistance partially fueled by me, production kills around a 1000000 people every year. one big downside to grafted farms is a fair way less efficient at producing meet these cows. i want to be 2 or 2 and a half, which is a rounding year longer than conventional operations. that means only 10 of them are cited every year. cows grow faster on feed lots, which makes it cheaper. meet you see mostly in by the very rich. so more efficient farming has made it more widely available. but progress, but you have to pay a premium. the costs of this meet is really high at $22.00 euro per kilo. for

comparison, the supermarket need is 10 the difference in price does speak to a difference in quality to the stuff to you. as long as i've fixed the size, as long as that 100 bucks, the manufacturing homes of china is a positive and most good thursday, fine, and i'm tired of that. i'm in the extra most intensive. i'm the time because i should never struggle except to get and respond. it puts the flashing in my suit. it quits the if i to encourage you to quality is also tied animal welfare as stressed animals make for worse, meet and on the lot. stressors are everywhere, eating green can cause ulcers and cattle, and they are often sick from the close quarters. transport and cattle is also stressful. so if you'd like to mit, less methane and meet is significantly cheaper. the grazing systems are better quality in animals, use less water and pollute less so far. they're winning on sustainability when viewed from a global scale, though, it's a different story. so a lot of discussions focus on the farm level for the food food system is massive.

its global janet wrong and asked and is an expert in calculating and evaluating greenhouse gas emissions. gene can't just focus on practices that might improve things at the bottom that we use. i flip, what is the system that and if the system level land use is the most important consideration, even including land to grow green, the lots use land more efficiently than grading systems according to german organic was that can only be about one full grown cow. perfect tear of land for scale one heck, there is roughly 2 american football fields that some lot of land which were running out globally. we're using 2 thirds of our land to raise livestock. as more people eat meat, more land is the for us to to use for past year. we're losing $3000000.00 hectares per year. this way, it's a huge problem, especially in the amazon rain for us 40 percent of tropical forest las occurs and present one of the world's largest beef producers production. there is also extremely inefficient and that's something that needs to change. one of the most

important things we do is to increase the productivity of livestock. and there's a huge client many people patient opportunity to do that because the productivity levels across the globe can vary by a 100 from one of the most hyped ways to increase productivity. is rotational grazing? it's a practice of intensively grazing an area and then moving the animals to let it recover. it's been used by shepherds around the world for centers and became popular in the 1950s in the us as a response to the greeting. pastor and climate change is putting it in the spotlight again, live stuff to address climate change and as advocate this ted talk has been viewed over a 1000000 times. your 3 key aspect of this technique. the more catalyst, dividing a passers and planting agrees invitation. instead of one cow per hector, think for their intensive grazing of a smaller area, stimulates plants to grow faster and put down deeper routes for a new plan. you. ready or a great team, but carefully,

you are able to extract the best nutrients all their forages. and therefore you are able to read you your read relative methane emissions. it will not fired, but based on their portfolio. more meaningful or more beef. rotational grazing is more efficient without the environmental impacts of the feed lot. field studies like this one is also shown that it improves. so quality and request is carmen via the cat grass grows sucking up c o 2, which is eaten by the animals. as a trembled inventor, the carbon is stored underground. the phone is going to by using it, they're producing carbon neutral beats. so these calculations don't really add up method, nitrous oxide are way more potent than c o 2. so this well would have to continuously store way more carbon to make up for the emissions and the animals. and that's just not how soil works. the amount of carbon, though defined a storage source is limited to some point you were rich. i've talked to the agent soils are also wildly different around the world to accomplish very complex when

you implement in practice to increase your company, you're at war with the microphone just and working perfectly. rotational grazing still uses a lot of land. studies have found around twice as much of feedback. it's not a silver bullet. the trouble is there is some familiar faces painting. it is one. this study was funded by general mills of grazing is carbon neutral. there's no reason for them to cut down on the production this movie about the benefits of rotational grazing was funded partially by show which uses the practice to offset fossil fuel emissions. but swell is not unless carbon sinks. so all setting oil doesn't make sense. and because rotational grazing uses more precious land, converting crock fields into pastor doesn't add up either, especially in places that produce massive amounts of meat. where it does make sense is places where people struggle to get enough protein or places with highly inefficient breathing systems. yes, we absolutely need to use these practices in places like columbia and countries in africa where these rotational partners actually restore. so helping increase

productivity that makes a huge lot of sense. another country where it makes a huge amount of sense is presented as the world's 2nd largest exporter of meet. improving efficiency will have a massive impact. rotational grazing could decrease deforestation and restore degraded areas. so if we continue to eat meat pie that's also have their place, but they need fixing and they can be more sustainable without making meet super expensive restrictions on the number of animals and requirements for them to have time outside improves animal welfare feed additives like algae can reduce methane emissions from cattle, nor can be treated to release less greenhouse gases, and not letting it sit for long periods of time can limit its impact. and large limiting antibiotic use and feed lots, reduced antibiotic resistance. no matter what though, this needs to go hand in hand with reduced consumption in some places. if we actually the limited beef consumption to about one and a half times the goose a week, we could to still continue to enjoy. so we can eat beef without ruining the planet,

sort of people in places like the u. s. and e, you need to eat lots of it. that's the most effective way for them to lower their carbon footprint. and whether through better grazing or feed lots, we can make the production more sustainable by improving efficiency. but even so, producing beef is not good for the environment. so ensuring we change the current system is absolutely key to a future level planet. so what do you think, friend or dinner is the account with us? can we eat them and still be sustainable? and because i got my shoes really dirty, please let us know in the comments and don't forget to subscribe. because we, we've got new videos every friday, the
