> it seems that the meat replacements are also becoming more popular

Which is very unfortunate, in my opinion. It might get people to switch to a more animal-friendly diet, but I simply can't think of how meat replacements are healthier than real meat.

What meat substitutes did you have in mind? How about tofu? Compared to say, cured meats, which contain cancer-causing nitrates, and far more heart disease-causing saturated fats, it's got to be significantly healthier.

And they're certainly healthier for the environment.

It really depends on what you call meat replacements. There are vegan dishes that can work as a decent barbecue sausage substitutes and I heard that synthetic-heme-based products can have a meaty feel... it's not like meat in super healthy when abused, so I wouldn't be surprised if a plant-based version could actually be better.

But if health is the main concern, the challenges are far greater than just meat consumption...

This is true in the US; and is becoming true elsewhere simply because meat has become so expensive. I know several friends who have gone vegetarian for a combination of health, financial and environmental benefits. It’s pretty common in progressive circles in the US at least.
