I only buy locally grown, free-range, organic meat

In all farms, regardless of how the lives of animals are before slaughter, animals die at a fraction of their lifespan. Farmed animals get killed as soon as their purpose is served, or as soon as they reach a profitable size. The definition of grass-fed, organic and free-range animals is very loose and can vary wildly. It doesn’t necessarily mean that the animals have any quality of life, it just means the farm has to meet some arbitrary requirements to earn that title.
