Genesis 1:30

1:30 And to all the animals of the earth, and to every bird of the air, and to all the creatures that move on the ground – everything that has the breath of life in it – I give every green plant for food.” It was so.

Ecclesiastes 2:21

2:21 For a man may do his work with wisdom, knowledge, and skill;

however, he must hand over the fruit of his labor as an inheritance

to someone else who did not work for it.

This also is futile, and an awful injustice!
