Environmental Warnings, why?

Real science isn't fun and largely would be a detriment, not a strength, for game design. It's the same reason why no game experience has realistic physics or chemistry. That doesn't mean games won't simulate those systems to a certain degree, but they will prioritize the fun and game experience over realism every single time. Whether deliberate or just carelessness with regard to realism, BioWare decided they wanted to require certain behavior from the player during specific periods in the game (Nomad only on the asteroid and limited exploration of Eos initially).

The Technical Director of The Legend of Zelda: Breath of the Wild gave a really insightful and thought-provoking lecture about why video games oftentimes create their own laws for physics and chemistry.
