Background information：The plastic rings that hold six-packs of beverage cans together pose a threat to wild animals, which often become entangled in the discarded rings and suffocate as a result.
Premise：Following our lead, all beverage companies will soon use only those rings consisting of a new plastic that disintegrates after only three days’ exposure to sunlight.
Conclusion：Once we all complete the switchover from the old to the new plastic rings, therefore, the threat of suffocation that plastic rings pose to wild animals will be eliminated.
Prephrase：在new plastic rings分解前同样也会对wild animals产生威胁

in most aquatic and woodland environments.-------------correct
(C) The new plastic rings are slightly less
expensive than the old rings.-------------------价钱动物窒息无关
(D) The new plastic rings rarely disintegrate

substances that are harmful to aquatic
animals when ingested in substantial
quantities by them.----------------这个威胁不是文中说的动物窒息威胁，文中说窒息会下降。
