Cargill ingredients are probably in every meal you eat. That makes the company's environmental goals a big deal.

• Cargill, the largest private company in the US, buys from farmers and ranchers in 70 countries.
• Insider spoke with Pilar Cruz, Cargill's chief sustainability officer, about its environmental work.
• The company has faced criticism over hazards including deforestation and greenhouse gas emissions.

Cargill buys corn, soy, palm oil, cocoa, and livestock from farmers and ranchers in 70 countries, then transports these goods around the world and processes them to be sold to companies like McDonald's and Nestlé.

That gives Cargill, which pulled in revenue of $165 billion in its last fiscal year, enormous power to improve the food system so it doesn't lead to deforestation and produce carbon dioxide and methane emissions that are frying the planet.
