Jesus. None of this actually matters, the cargo ships dwarf the output of a continent.
The entire worlds cargo ships emit 3% of the planets GHG emissions.
Animal agriculture is 15-20%. It's equal to the ENTIRE transport sector (cars, trucks, boats, planes etc).
As a consumer you can't easily change your cargo ship usage, or cars or planes, but you can absolutely change your diet, literally today.
I did! And I grew up on a dairy farm in rural NZ.
all of agriculture is only about 20%. animal agriculture is just a facet of that
Hahaha why do people just spout complete bullshit like they know anything.
A Poore and Nemeck 2008 meta-analysis covering 38,000 farms in 119 countries found that food systems contribute 26% of the planets GHG emissions, of which ~57% comes from animal ag. Meaning this study found ~15% of the entire planets GHG comes from animal ag.
Don't forget, 70% of the food we grow is fed directly to farm animals instead of humans.
Stop spewing bullshit and look up the data?
poore-nemecek 2018 found no such thing.
Which continent? Antarctica? It wouldn't surprise me, but it seems like an entirely useless comparison to make.
Not really, check out their claim on google. Ships are polluting a shitton. They have huge engines that run on the crappiest fuel known to man. It's so bad, that they have to switch to diesel by law when comming close to the shore / port so as to meet any semblence of environmental law. Something like the top 10 ships pollute more than all cars on Earth combined (exhaust gasses, not tire wear / brake dust).
I did check it ... doesn't seem to check out, not even close.
Here is a pretty neat interactive graphic: https://www.wri.org/insights/4-charts-explain-greenhouse-gas-emissions-countries-and-sectors
If you click on the energy -> transportation sector, you'll see it's about 80% from road traffic.
Over all ships only make up a tiny amount (0.3% of global emissions).
Is burning bunker fuel in international waters very polluting and should someone try to do something about it? Yes it is and yes they should. And the good news is that they have been working at it: https://www.imo.org/en/mediacentre/hottopics/pages/sulphur-2020.aspx
But were the more polluting cargo ships from the past more polluting than "a continent"? Probably only if that continent was not Asia, Europe, America or Africa. If they were and I'm wrong, then I would love to see a source. Telling me to "google it" is not a source, I already tried looking for it when I first asked the question and I could find no info about this claim. It seemed like a hyperbole comparison that they made up.
I also tried looking up your claim that 10 ships pollute more than all cars combined, and the first result was an article debunking a similar myth (about 15 ships): https://www.oldsaltblog.com/2021/04/no-sixteen-large-ships-do-no-pollute-more-than-all-the-cars-in-the-world/
Not going to claim it really matters that much. Everyone chooses their own principles and battles to make themselves feel better. We try to cut out as much meat as possible.
Beef, because it pollutes the most globally.
Most pork because they're clever and the nitrate pollution in my particular part of the world due to pig manure threatens the local ground water
So our chicken consumption went up a bit, but mostly the tofu consumption. Doesn't mean we're religious or even the least bit of preachy about it, god I hate those ppl. But it makes you feel better if you think you're at least a bit in control of some things. Like your own diet.
IDK why you're getting downvoted, a large cargo ship can emit the same amount of co2 as 50 million cars https://maritimepage.com/cargo-ship-co2-emissions/
Perhaps the people downvoting you are the same kind of people without a sense of proportion, who think that turning off an LED light bulb saves the environment.
It could also be that you don't provide a solution. So here it goes: want to cut co2? Buy locally produced goods. If you live in the northern hemisphere strawberries aren't in season in January, and it's a good chance that neither are tomatoes or avocado.
I mean, your own source debunks what the previous poster implied ....
They're getting downvotes for "not like it matters". Every little bit matters and "limit eating red meat" helps too. You don't need to completely stop.
Also the claim sounds weird to people who don't know facts about shipping and how horrific it is for the environment. Most people think "plane bad" not "ship bad".
Every little matters say the people who fly regularly...
