Do you like to eat avocados? Despite the fact, that the avocados are called superfood, you have to know that for only 1 kg of avocados you need 1000 l water. In Chile where the most avocados come from people are suffering, because they have too less water for themself. Water is something you can buy and not there for everyone. Here in Switzerland we have enough water for everyone. In Switzerland, the cold weather is probably more a problem when you want to grow avocados. Due to the climate change it could be possible that we could grow avocados in the south of europe or perhaps even here in Switzerland. Perhaps the cost of growing avocados in europe would be even smaller, than import them from South- and middle america. I am sure that from the ecological point of view it would make sense!
