There are multiple studies and writings on humans impact on the planet. Each focus is important but what is addressed here is how the silos cross influence. The impact may be by design or untended consequences of seemingly unrelated factors, but when mixed become a synthesis of actions beyond the original intent. Here the factors are featured and also the inter related results in the designed planet.
And I look at what the form of hominin-like would be if designed for best function rather than the surviving elements (good and less than premium) of evolution.
