Worse, biodegradable plastics designed to disintegrate, are increasingly common.

更糟的是，设计为可自行分解的可生物降解塑料正在日益普遍。

And that's true for both traditional and biodegradable plastics.

传统塑料和可降解塑料都是如此。

At the same time, there are enzymes that have been discovered and that are being optimized to make non-petroleum-derived biodegradable plastics.

与此同时，人们还发现并优化了不以石油为原料的可生物降解塑料。

We've also been able to program cells to make completely synthetic polymers containing the chemical linkages found in several classes of biodegradable plastics.

我们还能够对细胞进行编程，以制造完全合成的聚合物，其中包含在几类可生物降解塑料中发现的化学连接。

It's possible we can decrease further impacts by switching to biodegradable plastics, dumping less plastic in the oceans, or cleaning up the patches of sea most strewn with plastic.

我们有可能可以藉着改用可生物分解塑胶、丢较少塑胶到海洋里来减低更长远的冲击，或清理散布最多塑胶的海洋区。

This century we'll have to concentrate our innovations on addressing those problems— by reducing plastic use, developing biodegradable plastics, and finding new ways to recycle existing plastic.

本世纪，我们必须将创新集中在解决这些问题上——通过减少塑料的使用、开发可生物降解的塑料以及寻找回收现有塑料的新方法。
