Title says it all - from start to finish, you never see or hear any wildlife. Cooper has a farm but it's all corn - no livestock. Nobody is eating/using or even talking about animal products like milk or eggs. No mention of hunting or fishing, plus zero insects - even at the ball game, nobody is swatting flies or mosquitoes & other scenes show us having to clone & pollinate ourselves. Nobody has house pets like dogs or cats either. You're so focused on the rest of the story & effects that IMHO those small details get overlooked & underappreciated.
