Re: something is eating all our leaves on everything!
Just joined this forum and seen your unanswered(I think) post of 3 weeks ago.
Most species of caterpillar and other plant eating insect specialise on one or a few kinds of plant. Slugs and snails are general feeders on most vegetation, dead or alive, that is soft enough. As your damage is so widespread, I think mollusc damage is most likely. Of course you may have insect damage too on some plants, such as the turnip moth caterpillar on turnips and swedes.
