The following is a GRE-style sentence-completion question, where you must fill each blank with a suitable option from the three given. I emboldened the right choices.
For environmental advocates, the increased focus on ecoefficiency (measures to reduce negative environmental impact brought on by businesses processes) might seem (i) ______. Were these advocates more informed on the possible ramifications of ecoefficient practices, they would likely regard those businesses conforming to ecoefficient standards with (ii) ______. For one, businesses that conform to such standards and become profitable can reinvest this money into industries that are ecoinefficient, or these businesses, if wildly successful, can through sheer scale create more (iii) ______ than they did before.
an outdated approach
a counterproductive strategy
an unqualified gain
a conciliatory stance
Why is the answer for the last blank "waste"? Is it not a good thing to reinvest into businesses that are ecoinefficient (to make them ecoefficient)? Also if these businesses are "wildly successful" then can't they make more improvements (through other businesses?). I don't understand it. I can understand from the sentence before it that the last word probably has a negative connotation, but I don't understand the last sentence itself.
