Greenhouse gas levels dropped in the USA.

Upper Township - Greenhouse gas levels dropped in the USA. Why isn’t this in the headlines, as it is a positive thing? Isn’t this a great achievement? An interesting caveat to this is our nation has become the world's leading exporter of fossil fuels. Yet, we are emitting less CO2 gases into the atmosphere. Now, how can this be? This makes me question the validity of the whole approach to environmental issues.
