> When the first photosynthesizers started producing oxygen, it was a disaster for life on earth.-First, your example of photosynthesizers is speculation firstly, and secondly, it falls under the same categorical function as volcanism. It was initially (possibly) destructive, but actually worked to give rise to life. See this article: http://www.as.utexas.edu/astronomy/education/fall08/scalo/secure/309l_oct30_oxygen.pdf 

Abstract: The atmosphere has apparently been oxygenated since the 'Great Oxidation Event' ca 2.4 Ga ago, but when the photosynthetic oxygen production began is debatable. However, geological and geochemical evidence from older
sedimentary rocks indicates that oxygenic photosynthesis evolved well before this oxygenation event.-Secondly, from your link(I can not watch the videos because I am on a boat with limited bandwidth):-From what I can find about them though, nothing he says does anything to negate the negative impact we are having on ourselves and our biosphere.

What is the purpose of living? How about, 'to reduce needless suffering. It seems to me to be a worthy purpose.
