Logical Fallacies

My three fallacies:

   Either-or: "The entire planet must adopt a Vegan diet, or the human race will continue to suffer."
           -This paints an extreme picture that either every single person switches to the Vegan diet, or our lives will be miserable. Obviously, this not the case. If the human race switched to a Vegan diet, many health/environmental issues might be solved; but violence, war, prejudice, ignorance, mental illness, habitat destruction, etc. etc. would still exist. Adopting a Vegan diet would not end all suffering.

  Slippery Slope: "If we stop eating all animal products, as Vegan's persist, millions upon millions of wild animals will trample through the land."
          - The statement above implies that being Vegan would inevitably lead to this highly unlikely scenario. That is similar to saying if we only eat meat and no plant-based food, wild plants will grow thousands of feet tall and block the sun; a very unlikely outcome. This statement is set up to make veganism sound outrageous, so one reading would easily disregard that position.

  Oversimplification: "No one would get heart disease if every person was a Vegan."
          - Being vegan may greatly reduce your chances for heart disease and other illnesses, but many other factors play into this. Lack of physical fitness, smoking, drinking, and numerous factors all play a part in causing heart disease. This 'oversimplification' implies being Vegan is the solution. However, this is not the case, as many factors play into it.
