see plastic dating back 怎么理解结构

"We see plastic dating back to the 1960s and 1970s" says a scientist.

By reusing these plastic bottles, the center can build more nesting boxes for owls.

The center is now raising money to buy a ship that will collect plastic directly from the ocean.

Ocean plastic is a big problem for people who rely on fish and seafood for their diets.

How can we be sure that the fish we catch or buy is safe to eat.

老师，这里see plastic dating back 怎么理解结构？另外，为什么不是nest boxes ? 因为人们用塑料制作了鸟巢给猫头鹰，

所以不需要猫头鹰筑巢了，因此，这里使用nesting boxes 是否有误？

1 dating back to ... 为现在分词短语作plastic的定语。

2 nesting boxes为动名词作定语。动名词作定语，表示被修饰名词的用途——筑巢。所以这里用动名词作定语表示供猫头鹰筑巢用的盒子。这里不存在所谓的错误。
