First off, nobody is advocating killing anybody, please stop with that.
All I'm saying is that population growth is a legitimate issue and in the long term it's a good idea to encourage people to limit the number of kids they have. Especially people in rich countries like the US. That's all.
I just don't see you getting any utility out of that. People in rich countries naturally limit the number of kids they have anyways, but hardly anyone gonna limit their children for the sake of the planet when they won't even limit the number of cars in their driveway.
I think we SHOULD control population...by making sure that all women have access to education and access to health care and by removing food insecurity and destitute poverty. If we do those things, population issues will take care of themselves just like they have in literally every developed nation. That's why I don't focus on it.
I'm not a farmer or expert on the subject so I can't speak too much on how efficient organic food production is or could be, but everything I've ever seen on the subject suggests that simply switching to organic or getting rid of machines isn't going to solve all of our problems.
Organic farming is rarely enough
So do you think that SecAg Bergland was lying when he talked about what China was accomplishing? Or that most of China wasn't feeding its own people just fine? That would be odd as Bergland was a huge agribusiness advocate and went to China explicitly to sell American farming products to them. They (and many other examples) have proven for centuries that you can get high yields out of small holdings with non-chemical means. You just can't do it with any old "organic" farming, you have to specifically understand the right way to do it. In countries where land was at a premium for hundreds of years, they developed good means by trial-and-error before the colonialism of the farming industry wrecked things.
I'm not a farmer either but that's what my sister went to school for and I've read a lot of the old school experts, Albert Howard and Wendell Berry and shyt. There are a ton of issues with most of the studies because they measure agribusiness on favorable terms (which makes sense as most ag departments get significant funding from agribusiness and most ag professors were trained to accept the chemical/machine standard as gospel). They also lump all "organic" farmers together, when a lot of people are just doing "organic" for the sake of marketability and aren't actually using sustainable processes at all, they're just replacing Monsanto with other "approved" chemicals and otherwise making the same mistakes the non-organic farmers make.
Here's an article I ran into recently that shows almost a perfect little microcosm of what appropriate organic farming can do:
This 76-year-old organic farmer-scientist from Tamil Nadu has an inspiring story to tell
Note the important parts:
perennial instead of annual
zero waste - everything is converted back into soil
a long time to build superior yields because soil restoration is slow (something most of the studies completely ignore)
far higher and more efficient yields per acre and per plant
higher nutrition density in the product
intercrop planting
highly diversified fields rather than monocrop
control of product line from seed to jar
far less chemical contamination of product
uses far more labor
has to fight against government policies that favor agribusiness
Organic farming is a side issue, but that little story really hits on all the basics very well.
