I'm not sure that conducting a survey of everyday people's opinions about bees is really the best route to take in order to gain information that will help you with your particular project. Conducting a survey that is geared towards scientists or farmers that work specifically with bees, or pollination of crops, and asking them what they know about the problem, then asking them to reveal any thoughts they have about the potential causes of the problem and what they know about current solutions would push you deeper into relevant research.
In conducting a survey, it is important to tailor both your questions and your target audience (who you choose to survey) to best suit the needs of your particular problem, and assist you in attaining the information you MOST need to gain, thereby giving you meaningful insight into the nature of the problem itself that will lead you towards creating a solution.
In your case, you still need a clearer definition of the problem itself, and how it came to be.
