4. 5.1.1 - Define Pollution
“The addition to the
biosphere of any
substance or agent (such
as heat) by human
activity at a rate
greater than that at
which it can be rendered
harmless by the
environment, and which
has an appreciable effect
on the organisms within
it.”

Add something to the “The addition to the
ecosystem biosphere of any
substance or agent (such
as heat) by human
activity at a rate
greater than that at
which it can be rendered
harmless by the

Point-Source Pollution
easy to identify
impacts are localized (smaller area)
simpler +/or easier regulation
Non point-source pollution
harder to identify
many sources from large area
