       | Years ago, in a pool of improperly disposed of motor oil in the
       | corner of my ex-girlfriend's parent's yard, I was amazed to
       | discover mushrooms that started growing in the oil and looked
       | like they were consuming the oil. Each winter, when mushroom
       | conditions were ripest, they returned until the stump the pool of
       | oil gathered around sprouted new branches and started growing
       | again. Turns out there are species of mushrooms that consume oil
       | on the surface of the planet.
       | 
       | So this doesn't shock me at all, its an example of how regardless
       | of humanity's arrogance, life on Earth will be around long after
       | our species and its descendants cease to exist, to think
       | otherwise is to prove one's ignorance.

             | 
             | Damage to nature, as a general concept, can often shorten
             | lives, cause great harm to the living (warfare,
             | starvation), and cost enormous amounts of money - climate
             | change is very expensive. One reason is that we have
             | enormous amounts of fixed capital - 10,000 years worth, in
             | a way - invested in the ecosystems as they currently are,
             | including all our agriculture, ports, cities,
             | infrastructure, borders, food and water supply, etc. etc.
             | It will be very expensive and pointless to rebuild it all
             | for new ecosystems instead of just retaining what we have.
             | 
             | Also, most people agree that harming animals is also wrong,

             | angry and there are laws against it in most places.
             | 
             | And I think most people value what is 'natural' to some
             | degree; it seems like a common value of humanity across

         | The biology and evolutionary history of fungi is incredibly
         | fascinating.
         | 
         | To my (admittedly layman) understanding, they're sort of life's
         | premiere resource extractors. Their whole thing is breaking
         | down things that other life can't, so it's not surprising at
         | all that some species can consume oil.
         | 
         | We know they co-evolved with plants, and one theory suggests
         | that fungi allowed plants to make the jump from water to land
         | by using their hyphae to act as a proto-root system, unlock
         | nutrients like phosphorus from the soil, and transport water,
         | while early land plants provided sugars produced from
         | photosynthesis in return.
         | 
         | One of the main differentiations that might have led to the
         | split between proto-fungi and proto-animals is their nutrient
         | acquisition strategy. The organism that would become fungi had
         | extracellular digestion, while the organism that would become
         | animals captured and ingested other organisms.
         | 
         | This split led to different approaches to cellular adhesion
         | along with different developmental and signaling pathways
         | (different strategies for achieving homeostasis for instance).

         | If you want to read about some really wild stuff, look up the
         | Late Paleozoic era in the Carboniferous period. Basically
         | plants evolved Lignin (wood) but there was nothing in the world
         | that could break it down so it rapidly accumulated along with a
         | hyperoxgenated atmosphere due to the extensive growth. This
         | meant there were 8 foot long millipedes and dragonflies that
         | size of crows flying around. There were also massive forest
         | fires spanning the globe since fire was one of the only ways to
         | get rid of the lignin until, eventually, some fungi evolved to
         | take care of the problem.
