Thanks both of you.
I have adept farmers, but don't I need farming tech 3 to make a farm?
Unfortunately all the kids have grown up, and they don't want to have kids when they're starving, so I can't use the mushroom trick..
And they relly dont feel like researching besause they worry about food all the time

I'll try and see how long I can keep them alive

and then I maybe just have to start over..
But once again, thank you very much ;D
