How to write a petition
Develop your argument.
Before you start your petition, put some time into researching your topic thoroughly. Look at websites and literature about your cause.
Get an idea of not only what you want to change, but what the counterpoints to your arguments might be. If, for example, you want to petition your local government for a new park, look on your town's website regarding regulations and rules for parks.
