The best description was given by Jesus Christ when He told us,
Matthew 12:25
And Jesus knew their thoughts, and said unto them, Every kingdom divided against itself is brought to desolation; and every city or house divided against itself shall not stand:
The underlying reason we see that universally is because the enemy of humanity, and of God, has a great influence in this world. The world as we know it has been turned against God, and the ways of perfection with which it was originally created. God intends to return it to that perfection, after cleansing it thoroughly, but in the meantime we each must choose whether we will seek God's Truth, and the best way to live, or follow the enemy which will always lead to destruction.
No part of sinful humanity and our pride in inventions, will ever be able to "fix" what is broken, or to "escape" the tragic effects.
Life comes from the Creator God, and we obtain that life by seeking a relationship with Him. His message is in the Bible, and He will help us to learn the right way to go, if we become humble and willing.
His prophecy tells us that the current world conditions will worsen. The only safety is to meet with God and be on His side. He will at an appointed time, burn up all the pollution, sinful patterns, war machines, disease, and evil thoughts. Then He will recreate the earth in genuine restored perfection.
