Too much can be learned by animals. They have their purpose as our food, then why not medicine and other things? Limiting the used of animals isn't a wise step i think. There can be a big difference though between experimentation and cruelty.

There is much learned from animal experimentation that saves peoples lives. Tell them that you want to stop the only thing that could save their lives. Can you do THAT? Let humans die at the expense of ceasing animal testing. .
