Let say you got 100,000.0 euros (about 109,000.0 USD) or you already have them, will you try to establish a small zoo first. A more realistic approach that arguing about big zoo for wich are needed milions, if not bilions... and more people can actually try with these money, and in reality, smaller part of us will ever try to establish big modern zoo for wich are needed milions of money. So will you try with 100,000.0 euros, and what type of zoo would it be, the size of the whole zoo, the first animals that you will want/try/get in your zoo. Ok this sum of money has different power in different countries, but lets talk just for that sum of money. Eg. you can buy a Eastern green mamba for about 200.0 euros including transport, and plus antivenom for about 90.0 euros.
