Population & Food: Crash Course Geography #16
HTML-код
- Опубликовано: 2 авг 2024
- Today we’re going to talk about the link between population and food energy. As the world's population keeps growing, finding ways to provide enough food and water for everyone while supporting a sustainable environment can be tricky! We'll take a closer look at food chains and how energy is transferred between different trophic levels, follow the trends in human consumption as incomes rise, and talk about the two types of overpopulation as they're related to the planet's carrying capacity.

We are already producing enough food for everyone (and more). However, a lot of it gets thrown out: 1) at the production site because the food "doesn't look good enough for the customers"; 2) during transportation; 3) during processing; 4) at shops/restaurants/markets because lowering the price or giving it away is unacceptable for a capitalist society.
Came back to this channel after a very long time! Surprised to see the quality in information just as same as how it was years ago! Kudos!
0:04 The world deserves a chom chom sticker featuring Hank wearing a fruit hat.
I feel like this video really would have benefitted from a condmnation of ecofascism and other ideologies seeking to shift the burdon of growing population onto disadvantaged and indeginous communities, esp. those in the global south
I wish you would have also mentioned government programs that incentivize production of meat.
This video could have been useful few months ago for my food globalization assignment 😁Great job anyway
I don't even think this is the biggest problem. Do you know HOW MUCH food gets thrown out by restaurants and Super markets on a daily?! At least in the United States we waste food as if we can afford it. Yet there are children that starve at school and people that work 2 to 3 jobs to keep food in the table.
Yes, the waste and uneven distribution of food is a big problem. But as the video mentions, if people ate only plants, you could feed 10 to 20 times as many folks, compared to a diet with lots of meat. That is a much bigger difference than the 25% or so that is wasted.
Thank you for this
thanks for sharing
I think it’s beautiful how nature regulates itself through the decrease in nutritional yield per tropic level.
I learned more in this lesson than i've learned in all my... oh wait, it's been only 2 minutes since this was posted, I'll wait some more before posting this standard comment explaining why this is better than my university and etc.
If you're not learning anything at university, you picked the wrong major!
Make a viedo on Genetics in detail 🙏
Thank you❤️
Thank you.
Interesting video.
Great series. Thanks
With improvement in lifestyle and more affluence, people shift to meat based diet ..this is actually true ..but a slight exception in this is india ...here due to religions like hinduism , jainism and some sikhs (amrit).. even the affluant people do not eat meat due to religion ....
generally ..still many hindus jains and sikhs do eat meat a.aa.
Despite more people going vegan/vegetarian than ever, meat and dairy are subsidized to the point that not purchasing these products does not have the supply & demand effect people expect would influence animal industries to lower production. In the larger scheme of things, systemic policy issues are just as important if not more than individual consumer choices.
As a wise parent once said “ not every meal has to have an animal in it, just boil your vegetables and you’ll make a delicious soup!”
I’m paraphrasing atom Ragusea if you couldn’t tell.
Love love love❤️
Very helpful!
Lately, I have started to see a lot of information about the negative impact of meat production and consumption, and how a vegetarian diet can save us from the ecological crisis. There is a lot of scientific research showing that a heavily meat-based diet can increase the chance of stroke and diabetes. As this video claimed we can feed a lot more people if we reduce consumption of the meat. However, don't meat and crops have different nutrient and energy values? Any kind of meat contains much more calories than any type of vegetable if taken by the same weight. So you will have to eat much more vegetables and fruits than meat to supply your body with enough nutrients. This video also failed to mention that a lot of animal food cannot be eaten by people. For example, the wheat straws that is a byproduct of growing wheat are often fed to cows. While I believe that the scientific researches are somewhat right, I am sceptical about how the abandonment of meat consumption can actually help the problem.
Instead, we should talk more about the issue of the enormous amount of food waste. For example US wastes 30-40% of the total produces food. We need to be more conscious of how much we buy and produce to prevent it from going into the bin. It is also where animals can help, as they can eat unconsumed plants. Moreover, the wasted food can be used as a fuel source to produce energy like countries like Sweden are doing.
Animal ag uses 80% of agricultural land while only accounting for 18% of all calories. Eating animal products is a main contributor to climate change and food insecurity.
Please look up energy use in your own country to learn how you can reduce impact. Transportation and Households remain a huge part of the pie here in Canada. Even with Canada being a food exporter it's agriculture industry uses far less energy than either transportation, households (heating larger factor in Canada), or manufacturing on their own. Use less, buy local, and different regions are suited to grow different foods. The more suited the area is to produce a food, the less inputs/energy has to be used to grow that food etc. Also every internet posting about the subject seems to forget to mention that food production has become far more efficient with industrialization, economic pressure, education and lately technology. Less water used, less inputs used etc, there is a positive side to the story also.
The most efficient solution to food shortage would be Soylent Green.
Actually cannibalism would be more efficient solution since it would rapidly decrease the population which in turn would solve a number of social economic problems so it's kind of like 2 birds 1 stone.
Oh no, breeding humans for consumption is terribly inefficient.
@@michaelmayhem350 Soylent Green *is* cannibalism.
Or for a practical solution, just avoid animal products.
The Earth provides - If people had the skills and cohesion and compassion to share what they know everyone would have green roofs and walls and this concocted shortage wouldnt be happening at all
Yay!!!! I love an Iowa mention!!
I love your videos. If you understand this video, congratulations, you're smarter than average human.
This content is Sweet 😁
you havent even finished the video
Relevant😅
THANKSTOUGHTBUBBLE!
That shows y it’s awesome to be vegetarian. Wen i lovef in Sydney we bought Australian bananas
having an orange right now.
Sustainability isn't possible with our current population. We already use more resources than the earth can provide. This expectation that we'll just engineer our way out of the problem is folly, rather than admit the obvious fact that we can't expect endless returns from a finite resource. We'll hit the limit one day and the cascade of earths ecosystems will fail and we'll fight over the scraps.
This is where "modern"/"industrial" has to be seperated from colonialism and certain Western practices. It is well-studied that the current obsession with meat and its ties to affluence are unnatural and come from specific circumstances in America that have since been exported through soft power.
I don't like how you seem to be emphasizing personal responsibility, "eat these foods instead of those foods to save the planet", when in reality the issue is way more systemic, with stuff like economic influences and government decisions being way more decisive in what we eat.
Wow👌
I live rural. I kill my own meat, grow my own vegetables, make honey, make alcohol. I don't have a horse yet, but I will.
I think this is not correct, but what do I know. Research the next idea. The best way to grow the planets carrying capacity is by lifting people out of poverty. One way to do this is by making use of globalization. If I in the US buy the cheapest food it will surly come from a developing country were the work force is cheaper. By doing this I help them get out of poverty and they help themselves live better (that includes caring for the planet) :)
On the other hand there’re people, businesses, taxes, and workplaces that exist thanks to people’s consumption of meat. Transition includes many and many different steps and areas, not a simple equation like 1 meat eater equals 22 natural crop eaters. There’ll be a few generations before people change their eating behaviors, because people don’t change, they adapt.
Great video! Let's reduce meat consumption both for the environment and for the animals =) go vegan 🌿✌
Livestock feed is not necessarily consumable by humans. You and I can not consume Hay, but my cows can. Are there feilds that grow Livestock feed that could grow human feed? probably, but not all of them. And there are certainly pastures that'd be abject foolishness to farm crops as opposed to graze Livestock.
Not usually this guy, but IMO you definitely should’ve had a carve out to how like straight up evil factory farming is. This would have been the place to do it. That’s not unreasonable; you guys also take time to talk about indigenous land, or in cc philosophy Hank made a point to criticize certain philosophical systems if they had bad consequences.
There is such a thing as sustainable agriculture & animal husbandry. I am NOT going to eat bugs or live in a pod.
The biggest contribution you can make is to CHOOSE to have fewer children.
Then, it's all the other things... But they're tiny by comparison. They only slow our demise. Lowering our population is not optional. It's the one compulsory act. As a human has a set of minimum amounts of resources, water, food, it needs to just survive.
If we choose to have less than 2.1 kids, the world's population will shrink, and quicker than you think. Then we'll be able to enjoy having more things, eating more of what we like.
If we let the population keep growing, then we won't be able to enjoy as many of the things, eating what we want, and an increasing raft of other sacrifices, that won't be nice.
CHOOSE to have fewer kids. And do as much of the other things too.
More humans = Less humanity each.
Less humans = More humanity each.
I think this video is a little bit misleading. Don't get me wrong, I wholefuly believe that the current state of food consumption and the imense over-population world wide is a gigantic clusterf***, nevertheless the information here is misleading. For example, it's not completely true to say that a certain amount of grain can feed one person eating a cow or a few people eating the grain itself, because cows can digest food that people just can't! Biologically, cows can eat grass (which humans can't digest) and also the shells or casings of the grains that we eat. In factories that make corn/wheat/barley ready for human consumption, the put all the "humanly undigestable bi-products" in separate piles and sell them to farms to feed the cattle (or pigs or whatever). The cows don't get the human food, that other humans could have eaten, it gets our unwanted food. So in a sense, it's more ecologically to feed cows and humans from the same fields.
.
One big problem this video doesn't address: there's a huge difference between simply looking at the amount of calories consumed on the one hand, and providing the nutrients needed for optimal health on the other.
This isn't addressed, but it also isn't a problem. We obviously cant eat just grain, like that graphic seems to imply, but we can live healthier and MUCH more sustainably on plants using WAY less land.
This is a common problem. It's part of the reason why people believe we need to create more food to feed a growing population. They look at "world hunger" and think we need more food. What we really need is more socioeconomic equality. Most "world hunger" is actually malnutrition from the unequal distribution of food, as you pointed out. People in many pillaged countries subsist off of grains, and just like the first agriculturalists, they're suffering from malnutrition as a result. Ultimately, we don't need to grow more food, but to cap food production and start distributing what we make more equitably. Unfortunately, the very nature of civilization itself makes that impossible. (Read Ishmael by Daniel Quinn to learn more.)

Sorry for my bad english in advance.
I agree with most of what is talked about on this video but, the idea that, for example, eating grain/flour has the same "energy" as meat is just ridiculous. Lets say it takes 30Kg of cereal to make 1Kg of meat. Sure i could just eat the cereal, but the amout of cereal i would need to consume in order to have the same "energetic" value as the meat would be far superior to what a normal human stomach can handle. I love cereal, for real, and vegetarianism is wonderful, it can have great benifits for the health of some people and the planet. But you cant get the nutricional value, the minerals, the iron and the fats that we need. Futhermor, currently, 90-95 percent of domestic cow feed is made up of cereals that humans cannot consume.
We need to change our eating habbits but taking meat out of peoples diet can be costly long term in health problems and mal nutricion expecialy in poorer countries.
the flaw of vegan diets is less natural nutrition and need for artificial, higher consuming resources
Great info, time to go vegan
True, if we don't have any Bsk (Semi-Arid Steppes) climates. Take eastern Montana for example. That climate cannot sustain crops without significant irrigation which leads to issues in the water system. It is much better to leave that land for cattle ranching. It is all it is good for.
So true!! It’s not just about energy, but so much water and land is saved on a vegan diet, not to mention how horrible innocent animals are treated in factory farms.
We have enough food. But it is prevented from being distributed equitably by capitalism. We have so much food but it goes to waste if it can't be sold for a profit. It's insane and it's embarrassing to the entire human race. Let people eat, damn.

Convenient timing. Just eat the bugs everyone. Meat plant randomly "hacked" again. Surrrrreeee isn't a coincidence with this video dropping.
Perhaps human beings just stop reproducing for a couple generation.? Oh wait I forgot selfishness. Excellent video however very informed
With respect, you're talking about human nature, not selfishness. The drive to procreate is what insures the success of an organism. To quote somebody I forgot: humans are half animal, half angel.
