The document discusses why the speaker, Graham Hill, is a weekday vegetarian. Some key points made include: 1. Eating meat is bad for the environment due to pollution and the resources required to produce it, and many animals are killed for consumption. 2. Being a weekday vegetarian, or vegetarian Monday through Friday, means reducing one's environmental impact while still enjoying meat on weekends. 3. Some benefits of being vegetarian include lessening pollution, saving water, reducing risk of disease, and saving animals. The speaker chose not to be fully vegetarian because he still likes the taste of meat.
