I'm shocked that the article didn't mention this, but the mass die-offs we're seeing are because the world's coral reefs will be dead by 2050: https://www.independent.co.uk/environment/environment-90-per... https://www.businessinsider.com/great-barrier-reef-could-dis... https://www.forbes.com/sites/trevornace/2020/02/24/70-90-per...

Why a tech billionaire? We as humans just need to eat less animal food, and reduce our emissions as low as possible.

We need to start to understand as humankind that we're a pest to other life on this planet, be it animals, plants, naval lifeforms or anything else, us included (maybe except tardigrades, extremophiles and deep-sea creatures).

We need to reduce our numbers, and sustain that. Or embrace Musk's ideas.

With the way the human population is expanding and the rising income of 3rd world nations we are really going to look at a major increase in both genetically engineering food stock to be larger and more nutritious as well as ramping up lab grown meat. Conservation is clearly not going to work as so many nations ignore it anyway and quite often regulations lack teeth due to the fear of killing an industry. Its difficu…

> While I wish organically growing food and conservation was the answer, its unfortunately not. I recently had a lengthy discussion with some friends about their support of a solidary organic farm, where you pay a flat fee per month and get a box of whatever they have in that week. It's really hard for most people to understand that things like these are not sustainable and that it's purely a luxury product. Terms li…

The organic movement doesn't have to end with the whole world eating certified organic food to be successful. It can still serve as a standard bearer, leading a charge on a different way to do things- and industrial agriculture can take up some of its best ideas.

They don’t work. You will have gastro intestinal issues on plant only diets. All those vegan you tubers are cheating for a reason.

I'm a year into a daily vegan diet and haven't noticed this. When will my GI tract collapse?

No they aren’t. Organic for the most part is a myth. What they do is either spray with a pesticide that can be classified as organic (often nicotine derived) or create an island of organic surrounded by a conventional buffer. Often both.

>> Organic for the most part is a myth. What they do is either spray with a pesticide that can be classified as organic That's demonstrably untrue. Many organic methods use no pesticides at all because they use things like row covers or greenhouses which replaces them, or crop-timing to avoid source pests. Look at any farm inspired by Eliot Coleman methods, which can produce crops cost-competitively with conventional…

Some boutique farms for farmers markets can do that, the organic shit you get at Safeway is just organic pesticides

> I sure wish a tech billionaire would do something about this. I've noticed in tech that a common hope that people in tech hold is that "the billionaires", in their infinite wisdom and generosity, will pull magical solutions out of their hats and save us all. Like you mention later, yeah, right. > one of the thousand reasons I got out of tech Not an option I've considered much, but it's almost tempting.

It's because we can no longer rely on our governments to act responsibly or arrive at a solution. We now have to rely on the world's billionaires and their generosity for help.

Bezos can't just "buy" the world a new coral reef - it will require government authority, coordination between specialists, and a lot of collective buy-in by private individuals.

Unfortunately, the US has endured a multi-decade war against the bureaucracies that sparked the Interstate Highway system, the Internet, and countless other achievements.

If you're interested in adjusting your seafood eating habits towards eating more sustainable seafood, the Monterey Bay Aquarium maintains a guide on which seafood (based on species and location/method of catch) is most sustainable, somewhat sustainable, and not sustainable. My favorite version of the guide is the printable version that you can fold up and put in your wallet: https://www.seafoodwatch.org/seafood-recom…

I'd be interested in an EU or UK version of this if anyone can link?

seafoodwatch.org also has a list to other resources if you live in a country other than the USA: https://www.seafoodwatch.org/resources

When are people going to start acknowledging the elephant in the room: there are too many humans for us all to live western lifestyles, and unless we want our descendants to live vastly poorer lives we need to give serious attention to population control now.

Because there are alternatives to population control, like increasing the sustainability of food and energy sources. After all, the planet now supports twice as many people as it did a few decades ago, and that's basically down to agricultural yield improvements.

Making less humans seems to be morally taboo, no one wants to go there.

I buy canned sardines regularly. I've noticed for the last year that the size of the sardines are increasing, and many that are canned now have eggs. It makes me wonder if pressure is making them age and try to reproduce sooner than before, or if the fishing season is being expanded to meet demand. I've cut back on buying them as much. I may quit after this.

I too eat canned sardines regularly and have for many years, have not noticed any such thing.

There is a seasonality to them though, just like with most natural wild foods.

As far as wild-caught seafood goes Sardines are of least concern.

Based on some rough napkin calculations, the caloric efficiency by land of broccoli is about the same as industrial meat. Optimizing diet for land efficiency probably does not produce healthy diets. You can find strong evidence for this trade-off in the changes of average human health at the advent of agriculture.

> Based on some rough napkin calculations, the caloric efficiency by land of broccoli is about the same as industrial meat. Not even close. Did you forget to consider the inputs into meat? If you want to check against someone else's math, here's a paper that claims we can increase global calorie availability by 70% by shifting crops grown for animal feed (40% of crops in USA btw) to crops grown for human consumption:…

I did include the inputs, with the assumption of high efficiency feed for industrial meat production, i.e. a feed conversion rate of about 6.

This paper is about shifting animal corn to human corn, not about shifting animal corn to broccoli. Corn produces about 6 times as many calories per hectare as broccoli.
