The RSPCA are shocked at the study and now want zoos to give up their elephants.
They also want them to treat the ones they have better by giving them more pools, rubbing and scratching posts, mud wallows, and even heated rubber flooring.
The main problems zoo elephants have include:
There are about 500 elephants in Europe's zoos and circuses at the moment.
- Bad diets
- Not enough space
- Inadequate social groups
- Bad breeding programmes
- Rough treatment by keepers
