“Emissions of toxic and long-lived substances such as synthetic organic pollutants, heavy metal compounds and radioactive materials (emphasis added) represent some of the key human-driven changes to the planetary environment." according to their write-up at the Stockholm Institute.
I think a large flaw in these estimates is that it assumes current methods of farming. With hydroponics, gene editing, *stacked* greenhouses with artificial lighting etc we should be very much able to multiply the food output of food per land and resources used. Of course that's easier said than done but I think with enough government incentives it should be possible. That doesn't even necessarily need world wide incentives, if even one of the big players like the EU, the US, China or India were to demand limits on resource usage of food in some sort of supply chain regulation that would probably get us most of the way (and help with climate change at the same time, too). I fear that's still kinda unrealistic but as it doesn't have to necessarily happen all over night I think there is hope.
I don't know if that's entirely true. I am sure some of the studies did take into account increasing efficiency of agriculture (vertical farming, etc), which is how we can get to 15B+, but even that is more than 1 additional person fed for every person that exists today. Stacking a farm vertically is going to be part of the solution, as is leaving nature behind and using hydroponics, and artificial geochemistry -- but at the moment… we're not doing anything.
I discussed the idea of a one world government with a conservative friend of mine, and she responded with "but I'm proud to be an American." We need to come together as a human race if we ever hope to expand our horizons beyond our galaxy.
People always say the US needs to eat less because other countries need the food more. The USA has such a high amount of arable land and abundant freshwater that we produce more food than we could ever use. We could (and do) send that food overseas, but the problem isnt production, its transportation. We have no economically feasible way to send that food overseas without it rotting, and that is the problem. We either need to A: Improve transportation technology so that large amounts of food can be shipped to poor countries at a low cost. B:Improve Infastructure and solve issues that stifle food growth in poor countries. (Think of the Angolan Civil War which has crippled Angolan supply lines and made Luanda one of the most exspensive cities to live in.) C:Make hardier crops that can grow in less arable regions. The problem with both C and A, is that you still need that improved infastructure to move the food around a nation.
People worldwide need to be more exposed to the idea that having kids isn't 'just something you do' like getting a job or having a place to live, it's entirely a choice and it's not the right choice for many people. If you don't feel like it, it's not your duty, and in fact you'd have more money and time and freedom if you didn't have kids. Certainly in developed nations the birth rate would drop lower than it already is.
becoming vegetarian is so easy in India , you can eat burgers as tasty as meat made of potatoes for half a dollar , you can use potatoes no one needs lab grown meat
I do find the research (and please correct me if i'm wrong) quite biased to today's norms of feeding the planet. Or in other terms, loads and loads of land to grow crops and feed animals to in turn feed us. Let's take wheat as an example here. There are wildly different numbers of tonnes per acre depending on the country you look at. New zeeland and Europe are king in tonnes per acre data.oecd.org/agroutput/crop-production.htm yet there are so many places still performing just fractions of the top ones. So the first thing to get in order would be to raise all those other countries to be equal to the top ones. You don't lose or gain any land by that. It's just much more effective agriculture. Even then, you can raise output a shitload more! Wheat, under ideal circumstances, can grow much faster. When just using farm land you're stuck to nature and having a rough growing time of 8 months or so (for winter wheat that is). Wheat can grow at least twice as fast under LED light: www.hortidaily.com/article/6041827/wheat-grows-twice-as-fast-under-leds/ And that's only changing lighting conditions. If you go full on vertical farming you can optimize that further to 5 harvests/year! If you'd add growing layers (the vertical in vertical farming) you can get some truly insane crop yields. Read this paper for much more on that: www.pnas.org/content/117/32/19131 And this scales! So to summarize. I'm only highlighting wheat here and it already has a potential to be yielding many orders of magnitude more then is achieved "today" with the same agricultural land or even less (if the vertical farm route is used). The research for it is there. The experimental proof is there too. All that's needed is money to fund it.
Efficiency will get us part way, but Earth is not a robot. Soil depletion, ocean acidification and fresh water use are all issues even in the most developed agricultures. We need a better solution AND we need efficiency :D
@@TraceDominguez a little bit of a side question. Right now to make bread you'd first need dried wheat, turn it into flour, add a lot of water again and then bake it to get most of the water out. Does this sound super inefficient to you? It does to me. So I'm wondering, and you might perhaps be able find research that I've not been able to find. Why do we dry wheat at all if we just make it wet again. Can't we make bread directly from mashed most wheat grains without ever drying them? As if that's the case you can get even more crop yield. As for dried wheat. That would still be needed for storage purposes. I'm curious! :)
It's not that we need to pay people to eat less, populations are going down or are stable in most developed or developing countries. It's africa that's having a problem. No, I'm not racist, North America will grow to max 500 million people over the next century, Europe, South America, Asia will shrink. Africa will grow 4x. populationpyramid.net
So, if we pay people for having 2.1 kids, does that mean that every 10th family can have 3 kids or does it mean that every third kid gets cut down to 0.1? Jokes aside, awesome series! I love that Tom uses his channel to give amazing youtubers like you a bigger audience
10-15 billion people on planet earth is... is kinda still underpopulated. I expected it to be maybe a couple sextrillions to octrillions to be not underpopulated but also not overpopulated.
This is a technology, power, and heat problem. With better power sources (fusion or SSPS, or just ground solar and really good batteries) we can sustain our current lifestyle via more sustainable sources for materials, and better materials.
Nope , human body needs meat, plus bbq is the best, aint getting rid of any of it except, yes ill make 1 exception- fast food with meat and fast food all together, yuck, im so sick of it!
oh really? Go to curiositystream.com/trace and use promo code "trace" without the quotes. Someone messaged that they used it yesterday, if it doesn't work send me a tweet @tracedominguez and I'll get it checked out ASAP!
@@TraceDominguez what about a more sustainable way of hunting? Only taking animals that are to old too rear Young, or males that are to old too compete with the younger males. One deer can last me and my family for months, it saves the animal from arguably an worse death and keeps me away from store bought meats. A man can only farm so much. FYI I do have a garden in the summer that can last me for a few months after its planted in June and a few months after August when its all cut down before winter so I an rot and give some nutrients back to the soil befor the next year.

Oh and we also need to get rid of all the processed and chemical laden food too, thats where most if our obesity and cancers are coming from.
I agree more transparency in the food system is better, but "toxins" "chemicals" and "processing" doesn't mean what you think it means.
