High-tech pollution protection
Technology company Dyson has created headphones with a visor(面罩)to help people avoid polluted air. Called the Dyson Zone, it connects noise-canceling headphones with a visor that sits just in front of the nose and mouth, providing users with cleaned air. The product is designed (设 计) to fight against air and sound pollution.
Two-wheeled solution
On March 15, the UN General Assembly (联合国大会) passed a resolution supporting bicycles as a tool for dealing with climate (气 候)change. It calls on member countries to add bicycles to public transportation and encourages them to focus on bicycle-sharing services. The UN said transportation is the third-largest source of carbon dioxide(CO₂), a greenhouse gas that causes global warning. Choosing a bike over a car just once a day can reduce (减 少) a person's transportation carbon emissions (排放)by 67 percent, according to a University of Oxford study.
