It's funny to think that humans are somehow more sentient, more feeling than other beings. I believe other living beings are far more sentient - their bodies, instincts and senses taking score of change, always, as it comes. Plants, fungi, insects and non-human animals feel the impact of winds moving in new directions, pesticides in earth, chemicals in water and the sun shining stronger. Wings disintegrate. Forgotten pollen turns to dust. Mothers go missing and some eggs never hatch. Trees fall and soil grows weary.
They notice when something - or someone - in their food chain goes missing. Us, on the other hand - we carry on as if everything was just fine, blissfully disconnected from the delicate network of feeling and sense that is ecology.
We are the lords of adaptation, damned with the superpower to feel nothing at all.
