While the focus to date has been on microplastics in the ocean, microplastics in soils have largely been overlooked. Researchers are concerned about the lack of knowledge regarding potential consequences of microplastics in agricultural landscapes.
Two balsa rafts have sailed from Lima, Peru for the Easter Island. In six weeks the expedition will return after a trip of more than 5000 nautical miles. The rafts are equipped for full scale oceanographic research and the first attempt in our time to show how ancient mariners sailed the Pacifics.
Plastic in the form of very small particles, called ‘microplastic’, pollutes much of the marine environment. Scientists now find microplastics in the majority of samples collected from the world's oceans.
Rapid growth of the world’s population, especially in coastal regions, adds pressure on resources and land already approaching their physical limits. Scientists are designing platforms to combine industry and harbour activity with renewable energy, aquaculture and leisure.
