We just returned from a National Geographic guided tour of Alaska aboard the ship Sea Bird. The food served was all McDougall style: low-fat, vegan, and starch-based (with some very rich dessertsâ€”an option). The cruise line, Lindblad Expeditions, referred to us as â€œthe vegan, no oil charter.â€ Every aspect of this McDougall Adventure trip was excellent.
This was my third trip to Alaska (1993, 2001, and 2016). Massive melting of the glaciers was obvious and a topic frequently discussed among our group. However, our National Geographic guides, including one national park ranger, seldom mentioned the connection between global warming caused by human activities and the threat to these northern lands. Dwelling on this topic may have detracted from the travelersâ€™ enjoyment of their trip. I suppose no one wants to hear about the changes we all need to make in order to keep our planet healthy.
However, the â€œfood cardâ€ is the most essential one to play now in order for us to have some breathing room so that we can fix other issues like transportation and energy. Overnight the worldâ€™s human population could change from animal foods to starches (beans, corn, potatoes, rice, wheat, etc.) for the bulk of our calories. We could!
