Awareness is increasing about foods like lab-grown meat, insects and seaweed. These foods may help address environmental challenges, but it's important to be aware of both the costs and benefits.
According to some, meat "grown" in a laboratory would only have advantages: an end to animal abuse, preservation of the environment... But the reality is less idyllic.
Cultured meat comes from cells in a lab, not muscles in an animal. While regulatory and technological aspects are being worked out, less is known about whether people are up for eating this stuff.
