Sad post. The animal agriculture industry is the lead cause of global warming, and that matters. The meat industry contributes more to global warming than all the cars, trains and planes put together in a year.

On top of this, plants do not have the brain or nervous system necessary to process pain or suffering. Animals do.

Please watch Cowspiracy and What The Health. Seriously - they'll open your eyes.

Also the obvious point - no one can be completely perfect, but we can try our best. The definition of being vegan is to avoid animal products as far as POSSIBLE and PRACTICAL. Therefore, you can be 100% vegan.
