Did you hear? This summer’s Olympics will be the greenest yet. The Olympic Park is the first major new parkland developed in Europe in more than a century. The only way to get around is by foot, bike or via public transportation. Walking will be especially fun, as each step by the public will be channeled to a power source that lights the walkway. Between recycling, composting and less product packaging, Olympics organizers aim to send zero waste to the landfill. That gives us more than Team USA to cheer but Team Earth too.
