Oh I very much agree that UK, and likely the rest of the western world, will just continue to ignore the problem until there are actual famines happening. I'm just highlighting how easily this can happen. We're already seeing massive heat waves happening all over the world now, including cooler climates. There are already large scale crop failures happening in North America as well. It's only a matter of time until a famine occurs.

What China is doing with vertical farming is the solution to this problem, but there is little chance of that actually being implemented in the west.
