Why are the techno-barons so focused on human health? Not that there&#x27;s anything wrong with these efforts, but human disease is much less of a threat to our species and planet than an ever-increasing human population. What I&#x27;m saying is that humans have little difficulty reproducing; it&#x27;s a solved problem.<p>What&#x27;s not a solved problem is our disappearing fisheries[1], rhinos going extinct all over the place[2], farmland desertification[3], tropical deforestation[4], ocean acidification[5]... From my back of the envelope math, it seems that longer lives and a larger population will exacerbate our environmental and resource issues.<p>I&#x27;d like to see billionaires purchase large tracks of land simply for preservation. Cleaning up industrial waste from rivers. Foot the salaries of anti-poaching efforts. Get clean fusion energy production up and running. That sort of thing. Perhaps we should get our planet&#x27;s shit together before tackling immortality?<p>[1] <a href="http:&#x2F;&#x2F;www.washingtonpost.com&#x2F;posteverything&#x2F;wp&#x2F;2014&#x2F;06&#x2F;03&#x2F;the-end-of-fish&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.washingtonpost.com&#x2F;posteverything&#x2F;wp&#x2F;2014&#x2F;06&#x2F;03&#x2F;t...</a><p>[2] <a href="http:&#x2F;&#x2F;www.cnn.com&#x2F;2015&#x2F;04&#x2F;16&#x2F;africa&#x2F;kenya-northern-white-rhino&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.cnn.com&#x2F;2015&#x2F;04&#x2F;16&#x2F;africa&#x2F;kenya-northern-white-rh...</a><p>[3] <a href="http:&#x2F;&#x2F;www.bbc.com&#x2F;news&#x2F;world-africa-34790661" rel="nofollow">http:&#x2F;&#x2F;www.bbc.com&#x2F;news&#x2F;world-africa-34790661</a><p>[4] <a href="http:&#x2F;&#x2F;www.theguardian.com&#x2F;commentisfree&#x2F;2015&#x2F;oct&#x2F;30&#x2F;indonesia-fires-disaster-21st-century-world-media" rel="nofollow">http:&#x2F;&#x2F;www.theguardian.com&#x2F;commentisfree&#x2F;2015&#x2F;oct&#x2F;30&#x2F;indones...</a><p>[5] <a href="http:&#x2F;&#x2F;fm.kuac.org&#x2F;post&#x2F;increasing-ocean-acidity-threatens-marine-food-web-circumpolar-waters" rel="nofollow">http:&#x2F;&#x2F;fm.kuac.org&#x2F;post&#x2F;increasing-ocean-acidity-threatens-m...</a>
