Who cares? You're a single person and no one is forcing you to eat bugs, fungi, or fake meat.
These products are for the many millions of people who prefer an inexpensive alternative to meat.
Totally not true. They are going to drive up the cost of real meat and other livestock in the name of "climate change" and force regular people to opt for cheaper sources of food such as algae proteins, fake "meat", cricket flour, etc. Why do you think Bill Gates has invested heavily in this field? He is a monopolist first and technologist after.
How will they do this, exactly?
Also, isn't the cost of real meat too low as it is? It hasn't priced in climate externalities that other people (including non-meat-eaters) have to pay for. Shouldn't meat include all of its costs, not just the ones paid by the farmers?
Easy. Heavily regulate the farmers with climate regulations including carbon taxes. Or pass emissions laws like they have in the Netherlands which would force ranchers to downsize their herds. This would drive up cost to produce and scarcity of the product.
As for the second part of your comment I truly am not sure what you're talking about? It seems like your sentiment confirms the first part of my answer.
