If the world factories would have been working for 12 hours a day only for past 50 to 100 years, then only 50% of world's resources would have been consumed today. The world economy would have easily survived for another 100 years without any problem. There would have been no financial crisis and multi-trillion bailouts for next 100 years and more. The human greed to develop very fast and competition has led to the downfall of world economy ultimately. Example, if there is 200 storey building, you will reach the top of the building by elevator/lift or staircase. If you use elevator you reach the top in 2 minutes and then you have to come down. If you use staircase, you reach the top in 2 hours and then you come down. For past 50 to 100 years, world factories and manufacturing facilities have been working and producing products and goods for 24 hours a day and 365 days a year. That is the reason the world resources and raw materials are in serious trouble and world prices are sky-high because everything has been consumed in a short span of time. Human beings are breeding like rats and they say rats are breeding like rats. To feed the massive hunger (food and products) of 7.5 billion people, the world production works for 24 hours a day which further increases the population. All the world factories should be shut down for 12 hours a day. There should be death silence so that everybody and animals can rest in peace and the Earth can cool down for 12 hours a day.
