Food is more than just a means to an end, it's also a core part of human culture. We can't expect to fix cultural issues with money alone, even if philanthropists made it very easy to live a vegan lifestyle there would still be people who chose to eat meat regardless. It has to be a cultural change to stand a chance in succeeding, it's up to us as individuals to make this change.
I believe a lot of people would quit the luxurious flesh eating habits if someone as Bill Gates says he's a vegan and just states his reasons.
Yes, it would be a pretty hypocritical statement since he's probably having a bigger footprint than most of the people on the planet but still, he shouldn't force his meat-dairy-eggs culture onto the impoverished nations of Africa. He's doing exactly that, stating also that there are enormous health benefits to eating meat - being surely wrong.
From just energy perspective it's level-2 diet. Level-0 would be picking berries, trees, hunting animals etc., Level-1 is raising plants, level-2 is raising plants to raise animals.
From an energy perspective it is entirely irrational of him to support this in developing world.
No, Bill knows what he's talking about. Animal-based foods are the most nutritious foods for humans. Beef liver, for example, is one of the most nutrient-dense foods you can eat, outclassing vegetables in every way save fibre content.
Animal consumption is an evolutionarily and culturally significant behaviour. Arguments about energy usage aren't enough to overcome these things.
My estimate is that it's probably equivalent to several families dining on protein rich, nutrient rich grains throughout the whole year.
Your arguments that appeal to tradition, history, and culture, cannot be considered rational arguments. They also aren't derived from morals (product of rationalism). They are empty.
I wonder how did the Chinese solve their food crisis, I guess it was raising billions of cattle to feed their hungry people beef liver?
It's a luxurious food, not necessary, and given Bill's arguments - he obviously is missing the point. Given the recent WHO report and thousands of papers, including the discovery of mechanistic-molecular processes, causal link to meat consumption and heart disease (LDL cholesterol), they are just papers away from finding the causal link between cancer and meat consumption (sugars found in animal flesh alone). Given the huge amount of evidence it is not rational to call it a healthy food.
Freedom of Information Act documents reveal that the U.S. Department of Agriculture warned the egg industry that saying eggs are nutritious or safe may violate rules against false and misleading advertising.
Same will happen with dairy and milk, for dairy there are also hundreds of papers linking consumption with iron and calcium deficiency.
Claiming that meat, dairy and eggs is good food for developing nations is irrational, incorrect and contrary to the majority of evidence available.
Linking cigarettes with lung disease was done decades before they decided to make laws to ban the marketing. Thousands of papers were written, and everyone was denying it, because cigarettes were the cultural thing of the first-world countries. Call to tradition isn't a rational argument.
I don't think you've understood Bill Gates' position in our culture. He's clearly admired as a businessman and as a philanthropist, but I don't see much evidence that people are seeking to emulate his lifestyle choices.
Instead of waiting for Bill Gates to become a vegan, focus your energy on positive changes you can make. For example, want to encourage people to eat more vegetables? Why not start a cookery channel on YouTube that you can use to promote vegan food?
I'm doing plenty of positive changes while waiting and pointing out his irrational argumentation over energy.
One is replying here with a unique opinion.
The other is applying my own engineering skills, tied very tightly to logistics (NP-hard optimization).
Bill Gates is a huge driver for startups and people reinventing the food industry. But his posts on energy never include the biggest luxury of all, the mightiest polluter, the strongest destroyer, the most prolific murderer - the animal agriculture industry. Without it + great logistics, the greenhouse gases emissions he's so eager to reduce would reduce immensely.
When animal agriculture footprint becomes smaller than all traffic combined, when it becomes smaller than all of the heating - then I'll concentrate on other things.
Anyone profiling a program would optimize the big percentages, not the small ones. Having a couple of thousand people watching my region centered vegan cooking videos is nothing.
