What influences have humans had on your local environment, positive or negative?
Positive human impacts are generally limited to undoing problems humans have caused in the first place. [ At one time "positive impacts" were thought to be changing land which was just wastefully being "natural" into productive farms or cities.
Activities which improve damaged eco-systems include:
Ecosystems are reinstated
Pollution discharges are eliminated
Species are bred and
Foreign species are eliminated
Accumulations of contaminated sediments are removed
We exhale some carbon dioxide which assists green plants in survival
Our assistance in natural selection (culling) in some wild herds yield a less negative gene pool
The protected species laws assist in avoiding extinction
Use of new and different energy forms reduce pollution
Composting puts nutrients back into the earth, where they originally come from
"Re-greening" areas which have been subject to desertification
Reforestation of native lands ]
