Paleoclimatic records show clearly that the past 10,000 years, the Holocene, is a remarkably stable period in which we went from being a few hunters and gatherers to become more sedentary agriculture-based civilizations, which then moved us to the current populated modern era.

It is essential to ensure that the Fourth Industrial Revolution is a sustainable one for people and planet. It could even drive greater innovation, not only for short-term benefits and solutions for human wealth but also long-term solutions that benefit all and enable planetary stability.

There is an old belief that solving environmental problems can only be achieved by first building enough economic wealth so we can 'afford to save the environment.'

China leads the world in energy consumption, carbon emissions, and the release of major air and water pollutants, and the environmental impact is felt both regionally and globally.
