I agree with you about the plants... Sometimes, they just can't grow in a different climate... It's not just water, and sun, but very often the air humidity itself...
Food business is the number one best business but location is also the number one to consider. It will go along with the target market.
Very often it doesn't count that the food is great if the place is out of sight... :(
Yes, so we just need to enjoy the plants available and learn to share or barter or nowadays sell to others and buy from others too so we could taste different fruits.
Yes, location is very important in a food business too.
