How many more signs do we need? Is there evidence lacking that we have gone far astray from the morality to which our Creator calls us?
Proverbs 14:34 says that righteousness exalts a nation but sin is a disgrace to any people. As the prophet Hosea said (Hosea 8:7), we have sown the wind and reaped the whirlwhind.
Do not think that things cannot get worse. If we do not repent of our sins, they will get much worse.
