Answer:
plastic
Step-by-step explanation:
According to research by The Guardian, the US generates 34.5 million tons of plastic a year. Only 9% is recycled, with the remainder being exported to developing countries, which do not have the ability to properly manage their own plastic waste when it comes to waste from the US.
Among the waste generated by the US, plastic is the least recycled. This is a serious problem as it causes waste to accumulate in the wild and can destroy natural ecosystems and habitats.
