Lisa Jackson, former administrator of Environmental Protection Agency (US Environmental Protection Agency) and even Apple's vice president of environmental initiatives, was promoted.
As we can see on this page that highlights the company's chief executives, in addition to taking care of environmental initiatives, Jackson is now also responsible for Ma's political and social actions. This means that, in addition to being responsible for everything that involves the environment in Apple, she takes care of matters involving education and accessibility, as informed by the The Washington Post
According to a memo from Tim Cook to his employees, Jackson's new responsibilities are in line with Apple's dedication to "leaving the world better than when we found it."
Since taking over as CEO of Apple, Cook has been working hard on some fronts that until then were not at least part of Steve Jobs' management, such as the environment, social responsibility, diversity, etc. We, whether as consumers or simply citizens, have nothing to gain from this.
