In your cover story about the overfishing of tuna you give tips on what to do to help save the species [Nov. 9]. You forgot to mention the most effective way to protect the fish and the marine ecoystem: drop tuna from your diet; eat more vegetables.

Tuna has long been a standard item on my shopping list. Not anymore. A small contribution to conservation, perhaps, but one by one it may make a difference. Thank you TIME for regularly alerting readers to the planet's predicament.
