If your asking about ecosystems their are 2 types.... Aquatic and Terrestrial. Obviously one would choose terrestrial because aquatic is way more dangerous than on land.... Inside the terrestrial category their are many types of locations such as Grassland, Desert, Tundra, Forest, Rain forest, Swamps... I would choose Grassland because its the safest but can look dangerous with a few editing skills, For example you could be shooting a safari movie in the grassland and if you add a few wild animal sounds.... That's interesting!!!
Hope this helped!!! XD
