Zoos, pros and cons

Hi! i need help to see if this introduction is correct (puntuaction, structure, connectors, grammar...everything)
Thank you so much
Zoos
pros and cons

“All creatures are deserveing of a life free of from fear and pain”- Maura Cummings. This is why exits so many places that preserves and protects wildlife existlives; Zzoos, for example, are considered one of the best places that provides benefits to animals, at once while also that providinges entertainment to families. Around a 20% of the population in different cities visit a zoo per year; however, most of the animals are confined in small places and many other are overprotected. so, aAlthough zoos promote beneficial things such as conservation, appropriate nutrition and education are benefits promoted here, they also promote animal abuse, human amusement, and behavioral changes.

'Different cities' is not clear; if 20% of the populations in cities go to the zoo every year, just say in cities. If it's western cities, say western cities. A native English speaker would not say 'in different cities'; if you really want to say many cities say 'various cities', not 'different'.

Putting "human amusement" in with behavioral changes and animal abuse indicates that human amusement is an inherently bad thing, where earlier it seems like it is a good thing "provides benefits to animals while also provides entertainment to families"

By behavioral changes,  do you mean the animals rely on humans? If so, write "behavioral changes in the animals".
