What area of work should i go for?

Lets just say i hate the retail bullshit world. They could care less of people. They just want to make profits from people. Its just not me.. I want to make a difference and help in any way i can.. like Animals. I love animals. They need love and care.. I was thinking.. maybe the zoo.. jungle or dogs and cats at my local spca.. I just want to do something that can be helpful. Its something i have more interest in
