Hi So-Hi,
This statement had me posting…-
“Consider this a very good sign and proof positive that unless it is absolutely necessary for survival people will not want anything to do with taking a life in order to eat something tasty.”
You can not grow fruits in any type of hanging basket. It doesn’t work.
Did you try a good fence? 
I feel you on the moles. Once the population has grown, it is difficult to tame them. Probably one of the areas in your garden is a very suitable home to them. They love to live under compost or small woods etc.
Maybe at this moment it is not so cost-effective to convert your space into a food growing area for your own needs.
In general, it surely is possible to grow vegetable food with minimum detriment to small animals around. I’ve seen it done all over the world. 
Yes, cats and snakes are a must for me. I have 3 neighboring dogs which inhibit this from happening. I’ve never had a whole garden destroyed by moles, but it happened last year. I’d like to feed my family healthy organic foods, homegrown.
After some consideration and communication with someone allot wiser than me I realize how this topic I started might get really misunderstood.
Sorry did not mean to ruffle any feathers, I go along with what Yogani suggests for dietary considerations.
FYI I had a Turkey Sausage for dinner last night so I am not a food crank.
I am concerned about sustainability though and the welfare of those who inherit what we leave behind and will just leave it at that.
