Eat meat in moderation!
If you're a meat eater, consider reducing your meat consumption and going for quality rather than quantity. Production of meat consumes enormous amounts of energy, not only for the growth and transport of animal feed, but also for the heating, air conditioning, and lighting of the immense animal farms. Changing to a diet with less meat helps the environment, but is also good for your health. It is best to buy meat from local producers and buy organic too.
