As a matter of fact, that work is in progress:
Amazing, no?
That is amazingly cool. And the microorganisms aren’t even modified!
Science marches on.
But you can not compare a company’s decision to consistently use emission allowances intended to account for unintentional or unavoidable leaks as part of the company’s waste disposal policy, to an individual’s decidion to buy that cute little red convertible.
That is not a valid comparison.
Sure it is. It illustrates that most people have some idea that there is an acceptable level of safety at which it is not really that beneficial to keep spending money.
No, it is not.
Personal decisions effect a more limited number of persons, many of whom can influence that decision, and usually do not limit the decisions of other people.
The decisions made by companies effect a much wider range of people, which is the issue in the OP, most of whom can not have any effect on the decision, and the consequences of the decisions by a company can be, either in effect or in fact, impossible to avoid.
If you plan on surviving on canned tuna, I hope it’s light tuna rather than albacore, which contains high enough levels of mercury to be of concern if eaten more often than once a week. 
Just a little clarification on the Chicxulub crater in Mexico. The idea on an impact being responsible for a mass extinction was postulated before the discovery of the crater. The best evidence was the presence of iridium in the KT boundary.
The discovery, and dating, of the Chicxulub crater just allowed geologists to point to a specific event. There is still much debate on whether the extinction of the dinasours can be attributed to a single event as it took place over millions of years.
We’ll never know when we have enough information at our disposal. What defines a fool’s paradise is you don’t know when you’re living in it.
And yet you are obviously sure enough of the completeness of our knowledge of the toxicity of environmental estrogens that you dismiss concern over them as so much alarmist bullshit, brought on by the fact of our even knowing they are there.
