Renewable resources should be exploited in a manner such that:
(1) harvesting rates do not exceed regeneration rates; and
(2) waste emissions do not exceed the renewable assimilative capacity of the local environment.
B. Nonrenewable resources
Nonrenewable resources should be depleted at a rate equal to the rate of creation of renewable substitutes.

I'm sorry to have to say that the number of spam comment postings has required that we turn off anonymous comment posting. There's been a massive boom in what seems like computer-automated spam comments with links to web pages that advertise cheap, nasty, bad-for-you products, mostly cigarettes.
From now on, you'll have to be a registered user to comment on this blog.
If you had something you wanted to say, but really didn't want your name attached to it for some good reason, you should email Mick at mwomersley@unity.edu
I'll protect your confidentiality and post your comment for you.
