To letter writer Chuck Campbell, I say: Good luck with increasing U.S. oil production, which peaked in the 1970s and led to an ever increasing fraction of imported oil to fuel your SUV ("Increased domestic oil production is crucial for the United States," April 23).

If you want to frustrate OPEC, bicycle to work, walk to the store, eat locally produced food and stop buying plastics. You might also bother to read the peak oil page on Wikipedia.
