Is there any release from the corruption of nature and the darkness of ignorance?

Would anyone care to share their views on the following statement?

Abdu’l-Bahá says: —

In the world of nature the dominant note is the struggle
for existence—the result of which is the survival of the
fittest. The law of the survival of the fittest is the origin
of all difficulties. It is the cause of war and strife, hatred
and animosity, between human beings. In the world of
nature there is tyranny, egoism, aggression, overbearance,
usurpation of the rights of others and other blameworthy
attributes which are defects of the animal world. Therefore,
so long as the requirements of the natural world play
paramount part among the children of men, success and
prosperity are impossible. Nature is warlike, nature is
bloodthirsty, nature is tyrannical, for nature is unaware of
God the Almighty. That is why these cruel qualities are
natural to the animal world.

Therefore the Lord of mankind, having great love and
mercy, has caused the appearance of the prophets and the
revelation of the Holy Books, so that through divine education
humanity may be released from the corruption of
nature and the darkness of ignorance, be confirmed with
ideal virtues and spiritual attributes, and become the
dawning-place of merciful emotions. ...

A hundred thousand times, alas! that ignorant prejudice,
unnatural differences and antagonistic principles are
yet displayed by the nations of the world toward one another,
thus causing the retardation of general progress.

This retrogression comes from the fact that the principles
of divine civilization are completely abandoned, and the
teachings of the prophets are forgotten.
