Humankind's biggest challenge isn't climate change, large scale conflicts/wars, inequality or poverty. It is the origin of these challenges that poses most threat to our future. Reaching for the origin requires world view size upstream-system thinking. Our ecosystem is built on the principle of interconnectedness. While science allows us to understand few of the interactions in ecosystem, the entire image of our interconnectedness with other individuals, species and environment is still beyond our intellectual grasp. But we certainly understood the importance of having a system built on the principle of interconnection. As a result, we developed our social, economic and political systems that rely on our interconnectedness. The exponential growth in globalization continues to strengthen our bonds of interdependence every day. But the misconception that the greater fulfillment lies within hoarding more "toys" has deteriorated the truth of interconnection from our awareness. The resultant individualism born out of greed gives rise to our social issues and injustice. Only through the system thinking, we can understand this underlying cause of our struggle ranging from personal to global issues.
