Is it grammatically right to start a sentence using the phrase 'As there are/is'

Solution 1:

It's not at all true that you can't use a coordinating conjunction at the start of a sentence. (This is coming from a high school chick) (But it might not be somebody's policy or style to do so, but it's not un-grammatical. There is no rule that is being broken.) It's just what schools teach (for some odd reason) but there's nothing wrong with starting a sentence with "As". "As" isn't actually a coordinating conjunction, it's a subordinating conjunction. As far as I know, no one has ever claimed that you can't (as a preference or rule) start a sentence with a subordinating conjunction. (There is only a problem if the sentence that starts with a subordinating conjunction has a single clause.)
