Ship traffic between China and the United States accounts for 2. Air pollution created by ocean freight shipping between the United States and China causes health problems in multiple countries around the northern Pacific Ocean — not just in the two trade partners.
A team led by Huan Liu and her colleagues at Tsinghua University in Beijing analysed goods shipped by sea between the two countries inincluding US soya beans shipped to China and Chinese electronics shipped to the United States. The Sex cam Waiblingen also counted the number of ship journeys to calculate the amounts of greenhouse gases and air pollution emitted by the transportation of this cargo.
