13、can also degrade(降解) plastic. Experiments show the insect can break down the chemical bonds(键) of plastic in a similar way to absorb beeswax.Each year, about 80 million tons of the plastic are produced around the world.The plastic is used to make shopping bags, food packaging, one-off raincoat and o
14、ther things, but it can take hundreds of years to degrade completely. However, caterpillars can make holes in a plastic bag in under an hour.“The caterpillar will be the starting point.We need to understand the details under which this process operates.We hope to provide the technical solution to cu
