In a world saturated with words, you have created what I consider to be an uncommonly relevant and distinctly mature social voice. As you indicate, the time to act is now. One important thing each person can do to reduce threats related to global warming is to switch toward plant-based diets. Modern livestock-intensive agriculture and the consumption of animal products contribute great quantities of greenhouse gases. The burning of tropical forests to create areas for livestock releases tons of carbon dioxide into the atmosphere.
Cattle emit methane as part of their digestive process.
The large amounts of petrochemical fertilizers used to produce feed crops for grain-fed animals create significant amounts of nitrous oxides. Also, the increased refrigeration necessary to prevent animal products from spoiling adds chlorofluorocarbons to the atmosphere. Hence, for the health of our precious, but imperiled, planet, as well as for our own personal health, it is essential that we shift toward plant-based diets. I was in awe of the people in attendance and those who spoke. It was an honor and a privilege to be there.
