you know, some people were really squeamish about eating aquatic roaches, and they were reserved for penal colonies...but over time the public at large started to love them, they also gave them better names, like "crabs" and "lobsters".
some people do want to eat crab and lobsters, some don't.
it's not a naming issue or a perception issue, it's a choice issue.
The title is called "Is it time to start eating algae?" even...
The answer to the title is no, unless you want to, which you can already.
If it was about another option it would be a recipe article, not a climate change article.
