Today we're going to today talk about a really important aspect of the Christmas and holiday season - which is the transportation of cargo. Find out in this video how the Oceanbird and the International Maritime Organization are changing the industry.   There are a lot of cargo ships out on the sea and all of them burn fossil fuel! We always talk about traffic jams, our roads, and our cars because we see them every day. But, an even bigger problem comes with what's happening out on the ocean. There's so much poisoning of wildlife due to these old gas-guzzling machines.
