No. It’s doing things to take care of or monitor the environment. Making sure industries, businesses, and so on keep to environmental codes set out by the province. For example, collecting and analyzing water, air, soil samples; monitoring pollution in specific areas like conservation zones. It encompasses many things—my daughter had to collect certain types of insects in water/soil samples and look at them closely (under a microscope) to look for evidence (or lack of evidence) that certain areas were thriving or not. You might be thinking of domestic engineer (another term sometimes used to describe a housewife or maid).
I love this comic strip! The expression on little Pedro’s face—priceless!
