- A landfill on fire doesn't only emit a horrid stench - it has devastating consequences for the environment, too. The culprit is methane, an often underestimated greenhouse gas produced in large part by food systems, organic waste and yes, cow burps. Biochemical engineer Marcelo Mena explains the source of this sneaky pollutant, why its emissions need to be cut in half by 2050 - and what you can do to help.
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

#TED #TEDTalks #methane - วิทยาศาสตร์และเทคโนโลยี
Muito boa inciativa com a apresentação de um conjunto de medidas eficazes para cortar as emissões de CH4 que são muito mais danosas que as de CO2 . Faltou porem mencionar a geração de energia elétrica a partir do bio gas nos lixões ou land fill.
00:08 🌍 Landfills, like the Ghazipur landfill in Delhi, emit methane due to organic waste decomposition, contributing to harmful particulate matter and posing environmental risks.
00:37 📈 Methane from landfills in developing countries is a significant contributor to climate change, and emissions are expected to double by 2050 with increasing demand for goods and waste generation.
01:09 ⚡ Reducing methane emissions by half by 2050 is crucial to limit warming to 1.5 degrees Celsius while supporting development in the Global South.
01:37 🌡 Methane, though receiving less attention than carbon dioxide, has contributed to nearly half of the warming experienced and demands immediate reduction to effectively curb temperature rise within our lifetime.
02:06 💨 While addressing fossil fuel emissions is critical, focusing on food systems' emissions, which contribute 60 percent of methane emissions, is equally imperative.
03:09 🚮 Organic waste in landfills and food loss contributes significantly to methane emissions, with technologies like satellite monitoring aiding in pinpointing sources for mitigation.
04:44 🌍 Global initiatives, like Waste MAP, aim to intervene in major landfills worldwide, emphasizing the importance of stopping existing methane emissions and preventing new ones.
05:15 🔄 Organic waste diversion, such as composting, presents practical solutions to mitigate methane emissions from food waste.
05:46 🐄 Raising cows for dairy and meat is a significant source of methane emissions, with potential solutions focused on improving feeding, breeding, and animal welfare.
06:44 🌱 The Enteric Fermentation Research and Development Accelerator aims to reduce livestock emissions through innovative approaches, such as feeding algae or seaweed to animals.
08:20 💡 Addressing methane emissions benefits communities by improving living conditions, air quality, and food security, making immediate changes possible at a personal level.
cut to the chase man just say lets eat bugs. that seems to be the narrative lately
Someone help me here…
My food composting is good but that same food in a landfill becomes rotting organic matter.
Why doesn’t food waste compost in a landfill?
Good question! Two factors: (1) Oxygen. is needed to turn food scraps into compost. In landfills, compaction reduces oxygen and only bacteria that excrete methane survive and decompose the material. (2) Compost at minimum requires a balance of nitrogen and carbon, aka green and brown material. Landfills tend to lack a beneficial mix of food with brown material (leafs, wood chips, cardboard, etc.)
Hope this was helpful!
@@MckenziMacDowall
Yes, it does.
I line my compost bin with shakes from straw bales. That’s what I was taught to do.
Now I know why.
Thanks.
How about reducing livestock emissions by not eating from animals?
Farm Bill (if US based)!
Where do y ou think y ou r food comes from?
Every day in the world 40,000,000 gallons of fuel i evaporated into the atmosphere from just FILLING OUR TANKS! I know the focus is on carbon dioxide, but there are so many chemicals from paints, glues, fuels and, yes, methane. We can do better; we MUST do better!
Agriculture dumps more chemicals across the land than any other industry. Plus it’s also breaking small water cycles and causing desertification. So likely the worst problem we need to be focusing on in the coming 25 years.
I compost all my organic waste at home, to amend my vegetable garden. It's easy, cheap and even funny. Try!
What a poetic title for this Ted talk. Not the kind of poem I would want to read further though.
The speeker should not insist in developing countries and Subsaharian Africa, the major pollutants (even for methane) emitters are developed countries. This speech is not sincere.
no speech propagating the lie of gl obal wa rming is sincere.
I remember when TED talks were amazing.
Damnit Calgary 😂
When you think about this....house wrap is used to prevent methane gas from entering your basement. I like the message this sends. By doing some composting (which I thought about doing anyway via Lomi, not only am I reducing waste that goes in my landfill. When he talks about low quality food, you don't need a degree to understand this. Fried foods and fatty foods give you terrible digestion, while clean eating makes your life a lot easier. It would not kill anyone to listen to what he has to say.
yeah! lets make electric cows then!!
Everybody Stop Farting or put a plug in it.
Waving red flags for 30 years now. The obvious solution is to decrease animal consumption. Plant based is the most economical and viable solution for most of the regions that are creating the biggest problems.
I know! Methane is what caused Venus to overheat. Oh, wait...
Finally, some actual solutions that don’t vilify just one source and don’t expect cultural changes that have been around for tens of thousands of years
We have a simple solution that'll not only reduce the aniimal based emmissions but will also free the land, water, resource usage from these industries, it will help the poor, most of the UN's SDG goals will be achieved, will improve everyone"s health, will be an ethical way to treat the sentient beings of this planet... the one and only and the best solution is to eat WFPB bought locally... basically Becoming a vegan. DYOR too of course. 🙂
Beans create more cow burps from people than from cows. Don't blame the cows for vegetable waste doing the damage.
How much does a cow eat before you eat it?
@@12seth12 It's really rather irrelevant what a cow eats, a human wouldn't eat. They're either fed the rubbish that is removed from the land after we get ours, or they eat grass. Now would you eat grass, or the chaff from wheat?
The difference is, if they were on the land, they would feed the land. They rarely get to do that now, because of the grains that are grown instead.
@@12seth12 How much water do they use now, to grow grain that makes oils? it's now hauled up from a mile or more underground. Animals never had to do that. California is sinking.
Here's an idea.. how about humans stop drinking cows milk that's meant for baby cows so they can grow big fast.
To change this lobby the Farm Bill - up for renewal this year! The #1 reason we have so much meat and milk is gov’t incentives to produce corn and soybeans as back up energy supply. It’s not our insatiable appetite, it’s the gov’t outdated energy security policy (corn=ethanol and soy=renewable diesel). Conveniently a place to offload the excess supply of these commodities was met with the advent of CAFOs, processed foods, and dependence on food aid in developing countries. Call your representatives, Farm Bill renews only every 5 years and the policies are integral to what feeds all public school children and how 200 million acres of American farm land is used. 🌱
Why do we need baby cows to grow fast? Milk them or meat them?
What about reducing the 8 billion pieces of live stock we call humans?
Y ou first
@@guillermoelnino You just made the list, and lost the game as well.
@@DannyMaas Y ou lef tists always impose y ou r will onto others. What makes it worse is that y ou'd never accept the same being done to y ou.
@@guillermoelnino What's wrong with your spacebar? And why are you gullible enough to only come up with killing people for an answer?
The Anthropocene is coming to an end; All hail the Pyrocene! May the sixth mass extinction include the species that caused it. Enjoy what you can, while you still can; pity the generations to come.
I'm so sick of the animals getting the blame. When are we going to blame ourselves? We can't continue to keep breeding like mice and rats. People can't continue to multiply out of sight. When I was born, there were one and a half billion people. Now.. there are over eight and I have another ten years at least before I'm dead.
5% of all animals are Wild tru Animals, all other is man made for Marketing,u live in emotional jail,wake up❤
What we got to do is get the poor people to eat the scraps..... Deregulate McDonald's!!!!!
Bitcoin mining is a perfect solution for this.
How long will people be promoting the unproven ideas for that topic?
he is the CEO of this grift
Cool story bro how about you produce some ideas then...have you got any?
Methane comes out his mouth...
6th to comment
jeez why everyone hating lol
Just stop with the propaganda
Ur right it's too late,so Happy exitinction buddy❤
never 😎🗿
@@marnig9185it’s not, this comment will age poorly
Oh, give it a rest already!!
Yeah that's a great idea, let's put our head in the sand and pretend it doesn't exist!
@@Dez083you mean head in the water, because that's what she will be standing in eventually.
Yeah we will be dead soon, So just let pretend it’s not a threat. I have noticed rich never care, silly people same
@@GTChris How many kids do you plan on having, grand children, great grandchildren?
@@Dez083😊
It's not that relevant, just like most climate narratives.
Another big L for TED
So talking about the environment and methods on how to reduce climate change is not relevant and is another big L for Ted? Ummm ok can you please explain this one
@@Dez083 So, telling you that something is not that relevant to this is not relevant for you?
Ummm ok can you please explain this one without scientism and climate religion dogma
"Taking a single step is just not that relevant on a 1000 mile journey, so we shouldn't ever take that step." -- right-wing logic
@@sachamm "I don't even try to understand critiques of my worldview. I'll just make up whatever my opposition is meaning when they talk and wonder why things are getting worse" - leftist logic
What is more relevant? We have nutrient distribution issue that compost can fix. Cuts across human and environmental health, plus let’s embrace building beautiful again 😊
For a dose of optimism: search permaculture, regenerative agriculture, and Solar Punk
