I think the point is that the supply chains probably need upwards of years of time to adapt in some cases, you can’t just turn on a recipe that needs a full cup of blueberries per serving on Monday and expect there to be a spare million cups of blueberries to be lying around the supply chain on Tuesday.

In the case in animal product, there are almost certainly major operations worldwide that have been built and financed purely to serve McDonalds demand. They probably have to even build these out well before entering some markets.

They grow a lot of potatoes in the US. Last week I hauled a load of tater tots destined for McDonalds. I’ve hauled potato products for McDonalds quite often.

They raise a lot of chickens in the US. I’ve hauled chicken nuggets or chicken breasts for McDonald’s in the past quite often.

I can’t even tell you where they grow blueberries.
