environmental hazards

Some of my best memories are of the times I spent hiking and camping with my family as a child, Boy Scout, and on leave from the Navy.  I have great memories of swimming in rivers, lakes, and ponds; running for the park rangers when bears invaded our campsite, of watching the sunset over the ocean (or rise over the rim of a canyon).    What bothers me is that today, so many of these things can no longer be enjoyed.
Can a Livestock Revolution -- like Norman Borlaug's Green Revolution -- bring technological improvements to increase meat production in an environmentally responsible way? The Breakthrough Institute's whitepaper votes in the affirmative.
Smoking is bad. Bad for mom. Bad for the unborn and born baby alike. Now, a new study reinforces its adverse effect on the developing child, with a focus on the damage done to the kidneys.
