Yes, because we have so many chemicals in circulation now that, if we continue to add them, we will have continual problems. So if we're going to put forward a new chemical, we had better need it; there had better be a reason for doing so. If it's better at doing something than another product, then maybe that other product should be withdrawn, but we shouldn't keep adding to the total constantly.
