Does this study i did surprise you?!
Answers:
To be very honest, I think the premise of your study is skewed. People are vegan/vegetarians for reasons other than environmental. Just because someone gardens, it does not mean that they are doing it for the environment - it could be a hobby they took up just as one might, say, collect stamps. For one's own pleasure, rather than environmental reasons. Also something like a garden is a luxury that can be enjoyed for those with the time and the space for it.
Again I don't know what your sample space was, but for your numbers to have relevance (even if I discount the underlying faulty premise) your samples must be random and chosen from a large sample space.
I for one am a vegetarian, primarily because I cannot thinking of killing an animal to fill my stomach. And I firmly believe that a lot of vegans/vegetarians have chosen this lifestyle out of compassion, and not purely from an environmental perspective.
I appreciate the time you have taken to collect these statistics, I just don't think the conclusion drawn from them is accurate.
your study fell down when you "assumed"
you assumed wrongly
so your study is a moot point
definition of "study"
The pursuit of knowledge, as by reading, observation, or research. 2. Attentive scrutiny. 3. A branch of knowledge
your "study" wasnt based of fact, it was based on what you "assumed"
it has no merit
Your study is biased and is a convenience study, you are studying only a small portion of each population. You have no idea if anyone was telling the truth or not, or if they just wanted to make themselves look good. I consider the data flawed.
your sample size is way to small to draw any reliable conclusions
