Apple has teamed up with The Conservation Fund to purchase about 36,000 acres of private forestland in Maine and North Carolina, land that will be sustained and harvested for packaging future products, BuzzFeed's Ellen Cushing reports.

The Conservation Fund will manage the two tracts of land, which combine to be roughly two and a half times bigger than Manhattan. Apple — and other companies — will occasionally harvest the land in what's called the "working forest" model, which ensures the long-term economic stability of the forests.

In an announcement on Medium, Apple's head of HR Lisa Jackson and Conservation Fund CEO Larry Selzer said Apple will try to get 100% of its paper packaging from renewable resources.

"Apple is committed to zeroing out that impact by using paper more efficiently, increasing recycled paper content, sourcing paper sustainably, and conserving acreage of working forests around the world equivalent to its virgin paper footprint," Jackson and Selzer wrote.

Jackson was an administrator at the Environmental Protectin Agency from 2009 to 2013 before she joined Apple. And Apple has been heavily investing in renewable energy in recent years. The company's next headquarters will run on 100% renewable energy; it's developing a $850 million solar farm in California; and the company wants all its future stores and data centers to run on renewable energy, too.
