There are many sites on the internet that discuss noise issues in general, and the issues of "propane cannons and other noise polluting bird scare devices" in particular. The table below is an ever growing list of anti-noise web sites catagorized as follows:

• anti-noise sites that discuss the problems and impacts of noise in our every day lives.
• a list of world organizations and environmental groups that are concerned about noise, and what they are saying.
• provincial and federal government sites of interest concerning noise, legislation, farm practices, etc.
• city and municipal sites that tell us what our cities are and aren't doing about noise.

So one day when it's raining in British Columbia, or on a day when you have been driven inside by the incessant "Kapow" of propane cannons, surf through these many links and learn more about the harmful affects of noise, and what our governments are not doing about this problem.

You will see that our government's departments of agriculture actually promote the use of noisemakers that create a level of noise above the pain threshold of the human ear.
