The book delves into the critical role of forests in combating global warming through carbon absorption and oxygen production, while highlighting the negative impact of economic growth on forest resources. It addresses the lack of public interest in forest cultivation, despite the diverse ecological services forests provide. With Japanese forestry in decline and private operators struggling to maintain forest environments, the author advocates for policies aimed at sustainable economic growth and effective forest conservation.

The book extends the Frobenius theorem, traditionally applied to linear simultaneous systems, to explore its implications for nonlinear systems, particularly in economic analysis. It addresses the lack of discussion surrounding the conditions necessary for nonlinear systems to have nonnegative solutions, providing a comprehensive examination of this topic. By doing so, it enhances the understanding of the theorem's applicability beyond linear frameworks, offering valuable insights for economists and researchers interested in nonlinear dynamics.
