We are missing the big picture – factory-farm earth

Just one example, as Eric notes, is the enormity of tens of billions of animals unnecessarily and unsustainably bred, raised, transported and slaughtered for food, consumption of which is scientifically proven to be damaging to human health. Meat- and dairy-rich diets contribute to many life-threatening conditions, such as cardiovascular disease, stroke, high cholesterol, diabetes, bowel and other cancers. Also, the runoff from these slaughterhouses is polluting our ecosystems, rivers and oceans. 
I too would like to address Robin Grant’s vitriol in earlier letters. Animal rights advocates/activists are ordinary people, who care about our human and non-human earthlings and want to help them.
