Z_7 may be a smaller field, but it does not contain a copy of the positive integers. The elements of Z_7 are equivalence classes. These equivalence classes are subsets of Z which collectively contain all elements of Z+, but are not themselves integers. Since the elements of Z_7 are not integers, Z_7 does not contain a copy of Z+.
