Find out if any environmental organizations or consumer groups are involved in your issue and contact them for information and resources. If you have access to the Internet, you may want to visit the Web sites of environmental organizations to get an overview of programs and resources. Interview people in your community who are familiar with the issue. Don't be afraid to talk to the opposition - knowing their viewpoints can help strengthen your position. Try to get several sources of information for every topic.
Many information sources provide only one side of the story.
Relying solely on sources with a one-sided perspective will undermine your arguments and reduce your ability to make sound decisions. Present the results of your research so that your target audience will respect the accuracy of your information and the general public will understand what you are trying to say. Once the environmental issues have been defined and well researched, then it's time to put together a plan of action. Set a series of goals that represent what can be accomplished in a specific time frame. Know your target.
