Scientists admit that extinction is probably inevitable including mankind too due to the natural selection of nature. Some species just make it on Earth longer than others. The “meek shall inherit the earth” may simply mean the ants and cockroaches will outlast us all.
Scientists also claim that 99% of the Earth’s species have already gone extinct and that every 20 minutes another species may disappear. The only thing constant is change. Western civilizations should try to help Third World countries fight poverty and sickness but at some point you may have to ask yourself are you simply prolonging the inevitable?
Mother Nature has her own way of letting us know when we may be overpopulated, creating too many questionable concoctions and pushing the Earth’s resources to the limit and the Earth’s ability to accommodate and cope with all mankind’s creations and mutations by creating unstoppable forces like disease, fire and maybe even war.
With any kind of system, like eco-systems, man must learn to control it and use it without abusing it or it will end up controlling mankind. Ignorance leads to unrealistic expectations. Salvation is understanding and know-how.
