Policy and solutions / Re: Low GHG Meat
« on: July 18, 2019, 09:04:58 AM »
When talking about GHG emissions of livestock, Its not just the methane, but as you mention the mega-farms (over 1000 heads) consume a lot of fossil fuels in order to keep the feed flowing. If I understand the terms of COP resolutions/IPCC reports etc, we are supposed to reduce emissions to zero, and eventually take some carbon out of the atmosphere. This is NOT going to happen with industrial farming methods, or lab-grown meat, as every step of the process consumes high amounts of FF energy. (The production, distribution etc,.. of probiotics too) I hope this point is clear.

I agree with posters above, that the only real solution would be a drastic reduction in meat consumption, adapting of course to the place where you live. I.e. If you live in a mountainous region with lots of rain, and lots of grass, then the most efficient way of converting this solar energy into human-digestable protein is through a herbivore.  How are you supposed to grow protein and carbs otherwise in such an environment?

The following study shows that a proper 'intensive' grazing management could actually lead livestock to be a carbon sink.

Very interesting paper in Science on the MASSIVE sargassum blooms that have appeared in the Atlantic Ocean yearly since the start of this decade. The authors point to several culprits, including deforestation of the Amazon, agriculture fertilizer run-off, and a tinge of climate-change...

The publication is not free access but you can sci hub it. It's worth the read.

The sargassum problem is way bigger than just Mexican beaches. It affects wide areas of the caribbean. I saw the problem first hand last year, and it was astonishing to see nature's capacity for disruption.

For anyone interested this website is a great resource for tracking sargassum blooms:

They just posted a correction on twitter:
Quote
The 415.09 ppm value that appeared as the daily baseline for 3-May-2019 on certain graphics over the weekend was based upon a partial days data and incorrectly released on the website. The correct value for that date based upon the full 24 hour period is 414.15 ppm
