R Ranson, thank you for your thorough response.
We also prefer Europe over North America; regarding food but also culture and people. North America has some beautiful nature though, especially the NW Pacific.
But anyways, immigration to Canada or US would be difficult for us since we dont have any career going on. Also wouldnt be within our budget anyways.
Regarding 'enough rainfall'... this has not only to do with gardening. But also climates we prefer. It gives the air a fresh feel and makes us feel good. In dry climates, I have had problems breathing (Perth, Texas, Morocco).
For us, certain streams of immigrants or minorities can be something to avoid. This is our opinion and experience and I am not here to discuss that specific topic
However an example that is not political of nature and wont offend anyone could be, combining the topic of climate change and refugees... where would 156 million Bangladesh people go if the country would be flooded (if that were to happen due to climate change)? This can pose a problem to neighbouring countries, perhaps even Thailand.
Yes, it will be hard to find a country that suits us 100%.
