If you read all of the article, you will see that their stated intent is to restrict access to abortion pills. This is scary because a government agency is being weaponized to lay ground work to strip rights. Neither of the hormones in those pills are on a list of environmentally damaging things.
Given that the risk is restricting rights for a whole group of people vs an unproven. Risk to the environment, the prudent thing to do is test for the KNOWN harmful chemicals and focus on mitigating them in the environment.
I would be in support of researching and if, after research, it was discovered that those drugs are harmful, testing for and addressing them.
Tl;Dr There are big fish to fry in terms of environmentally damaging chemicals. Frying something that might not even be a fish, at the price of government intervention in a whole group of people, and, honestly, generation of children, is a terrible violation of privacy, and rights.
