Question

What are the different environmental principles and please explain each briefly?

Answer 1

You will need to read your textbook for the answer.

Answer 2

There are no single set of "Environmental Principals".  Like all words "principals" means different things in different settings and different people will have different values and perspectives on any given definition.

You need to restate your question to clarify the meaning.  You could be talking about scientific principals or principals of conduct and responsibility.
