Genetic suicide is when animals, plants, or humans, make a conscious decision to cease
procreation in order to reduce suffering to their community, their children, and the world around them.
Many animals (and humans) make the decision to take on genetic suicide, and this is because humanity has caused so much
destruction and suffering, that they would rather bow their heads gracefully and depart while they have any sense of
happiness.
The animals know that there is no use in reproducing when the odds are against them. They will not bring suffering unto their own species any longer than they feel they need to endure.
These animals do not trust human society to care for and guard their young into the future.
So in short, the animals would rather die and become extinct, rather than live with humanity.
