I have to write an argumentative essay on whether or not zoos are valuable to society. I have to consider economic, ethical, and scientific issues in my essay. My position is that zoos do serve a useful purpose. I need help with putting that information in a thesis statement.

This is an interesting paper and one that lends itself to a three point thesis statement.

A three-point thesis requires you to provide the three points you will be addressing and those often work as a mini-outline for your body paragraphs.. For example, "Zoos are ethically, economically, and scientifically valuable to society." This uses the wording of the assignment, provides three points for your body paragraphs, and also defines your position. 

You said that you feel zoos "serve a useful purpose," so you might add that wording. "Zoos are ethically, economically, and scientifically useful to society."

Remember each paragraph of your paper will provide evidence that shows why zoos are useful in each of those arenas, and you should also indicate who they are useful for. For example, when talking about how they are scientifically useful, who will benefit from the studies, research, etc... that occurs at zoos? When talking about the economic usefulness of a zoo, who benefits from the money earned by or spent on zoos? By reminding your reader who benefits, you more easily explain why the zoo can be viewed as "useful."
