I always wonder if i'm born as a chicken , duck or pig , what would i feel about human race with seemingly unlimited appetite for animal flesh,resourses & superficial power/glory at the expense of environmental destruction ?

I think evil coldblood monster is the best description that those 'low life' animals could think of us but of course this is just the perspective of the animals , not human, so their "subjective perspective" may not be worthy of discussion as according to many people.
There will come a time when the nature says enough is enough, and the human race, along with other animals will be transformed into different kind of energy form (via massive natural disaster or nukular disaster of some sort ) , readily absorbed by "low life" insect, trees , glass and plants to initiate the all new ecological balance . Hurrayyyy ..
