My version: According to recent surveys, vegetarianism has gradually become an alternative to meat doctrine. Perhaps those who have lately embraced vegetarianism were persuaded by the following saying of Master Buddha: "All ancient creatures were herbivores; after all, plants precede animals chronologically." A more faithful version: According to a recent survey, vegetarianism has gradually become a trend alternative to meat doctrine. This is not surprising, for as once Buddha said: "All ancient creatures were herbivores. After all, animals originated later than plants." Corrections: statistic survey - > recent survey (Most surveys are statistical, so it seems redundant) has gradually become a trend of an alternative -> has gradually become an alternative to (has gradually become suffices, you needn't trend. If you really wish to keep trend, you ought to erase that "of an", for alternative already acts as an adjective to trend) In addition to a saying of the Master Buddha, -> Perhaps those who have lately embraced vegetarianism were persuaded by the following saying of Master Buddha (As I was not sure about what you wanted to express I made some major changes, more fitting to the topic discussed... It appears that you want to express the cause of the trend, therefore, you should use a causal connector or construction instead of a copulative one (which serve to extend a point or give an example) "all ancient creatures were herbivores. After all, animal produced is the latter than plants." -> "All ancient creatures were herbivores; after all, plants precede animals chronologically." (The ; just seems more appropiate, as both clauses are semantically related. The second clause was quite strange so I remade it so as to render it more suitable to the topic; nevertheless, provided you change produced for originated, add an s to animals (for pl), change latter for later, and erase that the you should get a correct--albeit stoic--sentence) I hope it helps!
