In celebration of Earth Day, petfood brand Rachel Ray Nutrish is asking consumers to tell them how they celebrate Earth Day.

The petfood company's Earth Day campaign asks consumers to share their Earth Day celebration on the Nutrish Facebook page.

In 2012, Nutrish says it began adding up everything they do that releases carbon into the atmosphere, then invested in sustainable forestry programs that specialize in removing carbon. "So, in its simplest form, when you buy a bag of Nutrish, someone plants a tree," the company says.
