The sentence where I have a problem(at the end of the article):
"このままでは東京オリンピックを境に、数年以内に繁殖農家の“大廃業時代”が訪れる懸念があるのです。"
I don't understand because it doesn't fit the context.廃業 of 繁殖農家 won't be aggraved by the Olympics because the problem isn't about the demand but rather about a lack of japanese people to continue this activity, even if the demand grows bigger because of the Olympics, it won't make 繁殖農家 disappear further if I'm not mistaken.
