And one of the species fungi can help preserve is us--homo sapiens sapiens. Mushrooms are rapidly becoming recognized as one of the superfoods for a healthy human diet.
Quote: All we have to do is to look at modern agricultural practices, including GM farming techniques, to observe the extent at which we are destroying biodiversity, on both micro- (microbial life) and macro- (flora and fauna) levels. For instance, it is no mystery that monoculturing, i.e. growing only a very select number of plants on massive tracts of land, requiring the destruction of all competing plants and insects and animals that could damage or consume them, is contributing to the mass exit of species from this planet. Clearly, the way we chose to produce and consume food is a primary driver in either progressing or decelerating (and perhaps reversing) the extinction event we are presently experiencing. The implication is that if we focus on developing sustainable agricultural practices (e.g. biodynamic-, permaculture-, and otherwise truly organically based farming practices) we will slowly but surely change the deadly course we are on and stimulate the regeneration of the biosphere.
