Cowspiracy: The Sustainability Secret tackles the tough topic of environmental conservation through a new angle. Instead of focusing on things like deforestation or a lack of recycling, filmmaker Kip Andersen argues that animal agricultural practices are the primary cause of environmental issues.

The documentary follows Andersen’s journey as he attempts to uncover the truth behind the environmentally problematic behaviour of the animal ranching industry. Along the way he faces lies, hostility, and even outright threats. These obstacles only make him more determined to discover the true cost of raising animals for food.

Cowspiracy is able to make a compelling case that a great deal of modern environmental damage comes from the unsustainable practices of those supplying people with their meat, dairy, and eggs. It offers some hope in this time of global warming by suggesting that the burgeoning population of Earth can be fed in a more sustainable, plant-based manner.
