Simple lack of a regular supply is a food security issue.

It has to be replaced and ensuring the alternative exist is an issue that takes land and effort.

At a time when farms harvest have failed. Alternatives also have issues.

Stop looking for reasons not to care.

You clearly lack any understanding of food supply.

It takes 4 to 6 months to grow a new crop. Not to mention free growing land is hardly available.

Add to that a couple of years to expand current production facilities. No a huge source of current protine is in no way instantly replaceable with plant milk.

Historically yes taste has negative affects on citizens health. Look at WW2 war history of trying to force replace products in the past. You cannot force folks to consume things they dislike health is lost historically. Even in a war setting it has issues.

It takes huge time and investment and yes societies health is seriously effected by refusal to accept the replacement.

Your attitude seems childish in many ways. Based entirely on your own perceived importance of a high Y used product. With no understating of what is involved in actually replacing such products. Or what happens to non milked cows if dairly farms fail.

I have no issue with blaming those responsible. But yes any lose of a hugely used food source is a seriose issue.
