What Seaweed and Cow Burps Have to Do with Climate Change | Ermias Kebreab | TED Countdown

Scientists have long known that cows are a huge source of the greenhouse gas methane, contributing up to four percent of emissions globally. But could there be a way to make cattle less -- ahem -- gassy? Animal scientist Ermias Kebreab talks through an ingenious solution to reduce methane-rich cow burps by feeding cattle something growing below the surface of the ocean: seaweed.
Countdown is TED's global initiative to accelerate solutions to the climate crisis. The goal: to build a better future by cutting greenhouse gas emissions in half by 2030, in the race to a zero-carbon world. Get involved at countdown.ted.com/sign-up

@@greggary7217 I've seen a lot of research along these lines coming out of California universities as well. Unrelated studies that have had very similar results, so there hasn't been any issue with repeatability. I think one of my local universities has also worked on it with similar results as well.

Hmm hopefully they can do it right so the cultivation process and transportation\distribution of the seaweed is not going to cancel out the reduction in methane emissions...

@familywilliams4058 2 года назад

I am very interested in trying to combine seaweed and land based shellfish production together for this reason. I love shrimp, but they are very messy animals. If I can clean up their effluent by growing algae for dairy cows, then I can also feel much better about my love for milk and cheese too.

This has very limited upside potential due to methane’s high turnover in the atmosphere. Better to support pasture raised cattle, which is a net carbon SINK when properly managed.

@greggary7217 2 года назад

I’ve seen conflicting opinions on carbon sink properties of grass-fed - if you have any refs to studies not funded by the cattle folks I’d be hugely interested in hanging them!

@yekmer 2 года назад

This is a good effort to help reducing carbon emissions. Though there are lots of problems with animal industry. Land usage, agricultural land usage to feed animals, chemical pollution from the way we raise animals and land, excess antibiotic usage, animal abuse etc. These kind of solutions are small fixes to a bigger problem. It will make people eat their burgers with more relaxed mindset. Because we humans first believe, then find arguments to fit into our believes. I know this because I do this all the time.

So far I just thought that stopping eating beef and becoming a vegetarian is the the only way individuals can do for the climate change. But now I got a wider view of action to solve this problem. Thank you a lot. It is very interesting, impressed, and I am going to share this video with my GHG lab colleagues tomorrow!

@greggary7217 2 года назад

Don’t forget that this doesn’t solve two other problems 1. The entire production sequence from crops ,feed and abattoir produces at least as much CO2 as the burps. 2. The water used to feed the huge crop needed to feed them, is literally decimating western aquifers & putting western US cities at legit risk of critical water shortages. At some point we are going to choose - beef & milk or water. Oh and there are /lots/ of other ways to help :-)

@greggary7217 2 года назад

Great news as far as it goes - now if we can just get cows & the crops it takes to grow their feed, from decimating western aquifers & placing the entire western US in legit danger of critical water shortages, long before the climate could kill us. Bit of a downer I know, but there it is As for plant based diets - I’m not even a vegan never mind WFPB but there is a growing population that are, and who get perfectly acceptable B12 & A from proper diet construction & where necessary, supplements. There is no reason that can’t happen almost anywhere. I also question the 4% emissions number - when the entire production chain is counted it is meaningfully higher, none of which is addressed by burp suppression. All in all I really want to know who funded these studies.

@familywilliams4058 2 года назад

Most of the western US grows food crops for humans (think of all the orchards), not cattle. that's mostly grown in Midwest "corn belt" though I agree that it needs addressed. I recently saw a very interesting business that was using hydroponics to grow wheat grass for dairy cattle year round. They used 90% less water and ran off of solar panels. The system was almost completely automated.

@greggary7217 2 года назад

@@familywilliams4058 I’m for any progress of course - I watched a documentary on water shortages in the west, it was pretty clear that growing feed was a significant problem for the western aquifers. I don’t recall specific numbers , I’ll watch again just to see

@Noukz37 2 года назад

The best way to solve a problem is to address the cause, so you prevent it from happening. Cow digestive tracts have evolved to eat land grass, not sea grass. Of course they were burping methane because we were feeding them legumes and grain. And if seaweed is so amazing (which it is), why don't WE eat it directly then, and bypass the livestock completely? Because this speech is not about solving the issue, it's a greenwashing distraction.

@boatraft 2 года назад

He addresses this in his talk. And it's pretty unfair to call this thoughtful, well supported presentation "greenwashing".

@user-er9cb3hx5t Месяц назад

In many countries (esp. in Asia) where legumes are part of people's diets, garlic when used as seasoning has a similar beneficial effect on humans (w.r.t. flatulence and burps).

@ethangilbert8131 Год назад

The problem is simple: there are too many cows. Feeding them seaweed is not the answer, reducing animal agriculture is. Why is it so hard for such smart people to say this?

@luciagrillo5480 2 года назад

Ok I have a better idea: why don’t we just stop eating animals

@mikedelima1219 2 года назад

One can have a healthy and joyful life with a plant-base diet only. Seaweed it's not the Holy Grail. What about water consumption, deforestation, animal cruelty, and health problems? It's not only about methane. Reduce meat and dairy products consumption helps to solve many other problems as well, besides CO2 and methane.

He addresses this in the talk. Most people who can simply wont. And as for the people who can't, meat and dairy provide them with essential nutrients their diet would otherwise lack. But yeah, I agree that most well-developed populations would be better off consuming less meat.

@davidgeorge8325 Год назад

B12 comes from bacteria. There are vegan sources of B12. As far as the stunting figures… he conveniently used the data from a malnutrition study that had nothing to do with beef consumption. A total misrepresentation of data there.
