I looked this question up to see if it had answer choices, but I wasn't able to find any. So I will give you a general answer that may help you in case it does have answer choices.
Answer and Explanation:
The sentence "I want to find that cowrie shell. I search through seaweed heaped upon the sand, but all I find are beer can rings and plastic bottle tops" shows people's disrespect toward nature. It is easier to find plastic everywhere than it is to find natural shells in heaps of seaweed.
Most people do not seem to care that our actions influence the whole delicate system of our planet. Our waste is usually not properly disposed of, and industries keep on producing materials that are not recyclable or degradable. This has a harmful impact over other beings. The can rings and bottle tops mentioned in the sentence, for instance, are polluting and destroying habitats. If swallowed by fish and birds, for example, they will most likely end up making them sick or even killing them.
