The Two $20 Trillion Opportunities is the third and final part of a series dedicated to offering innovative solutions to ease problems tied to global warming, climate change, rising ocean coastlines, biodiversity loss, desertification, ocean pollution, and the depletion of fresh water.

The first book in the series-Building the Climate Change Bridge-explored how we can transition from relying on fossil fuels to green energy. More importantly, it proposed a bridge for getting from here to there.

The second book-Defeating the New Axis Powers-focused on the geopolitical issues related to climate change.

This final book in the series lays out a plan to create what author James Michael Matthew calls "the selfless economy." He reveals how to pay for both building a climate bridge and creating a selfless economy.

As our collective concern about the future of our planet grows, there has never been a more critical time to explore how humanity can pursue responsible and practical strategies to move forward and ensure our future.
