M3.8 PDC+++ : M3.8 PDC+++ Biodiversity is the variety of life in all its forms, levels & combinations. To maintain the biodiversity of the Gaian organism is of vital importance because each species represents a node of connexion in the complex web of Life which sustains us. At the moment our industrial & highly consumerist civilization is responsible for the disappearance of some 200 species per day. These are converted into human biomass on a daily basis, but we're destroying the foundation that support our own survival. So there is a big job to do. In this class we explore some direct ways of increasing biodiversity at a local level, like seed recuperation, habitat protection, & starting to change our diet in a conscious way so that it adapts better to the indigenous ecosystem of our region, instead of trying to adapt nature to our whims. of the PDC + + + M3.8 BIODIVERSITY an integral exploration
wangari maathai : wangari maathai "Until you dig a hole, plant a tree, you water it & make it survive, you haven't done a thing. You're just talking" “The essential role of the environment is still marginal in discussions about poverty. While we continue to debate these initiatives, environmental degradation, including the loss of biodiversity and topsoil, accelerates, causing development efforts to falter.” Kenia, 1 April 1940 - 25 September 2011

Biodiversity : Biodiversity Biodiversity is the variety of life on Earth, from the genes to species and populations to the complex ecosystems in which they live
14 million species : 14 million species is an an estimate of the biodiversity of the Earth we've only documented 1.7 million habitat destruction & pollution play major roles in destroying animal & plant species 2004 team of scientist estimated that 15 to 37% will extinct due to global warming
Importance of Biodiversity : Importance of Biodiversity Biodiversity is crucially important also because because the Earth's Vital Cycles depend on a great variety of organisms Our lives depend on preserving biodiversity "EarthCare" as an ethic implies that we take care of all of Earth's creatures' rights to thrive.
PowerPoint Presentation : Importance of Biodiversity Climate change will severely test ecosystems' resilience , & resilience is a factor of biodiversity
PowerPoint Presentation : we are all "odd-balls" And it is our weirdness interacting with other people weirdness that CREATES BIODIVERSITY CULTURALDIVERSITY
PowerPoint Presentation : a Social Model (RC) owning class working class sexism classism racism adultism/ageism isolated BY OPPRESSIONS (which are combinations of PATTERNS) ISOLATION is the pattern we perceive but INSIDE each group there is also tension The Oppressions (inner and outer) don't allow us to appreciate a care for our diversity
PowerPoint Presentation : Internalized Oppression External Oppression (institutions & people who limit & batter us from outside) (patterns that limit & batter us from the inside) LOTS OF PRESSURE!! eg. adultism sexism racism classism ... > we attempt to ‘liberate’ it by acting as oppressors whenever the opportunity presents itself (= PERPETUATES the pattern) > or we anesthetize ourselves (drugs of any kind: it's their function = PERPETUATES the pattern)

Seeds : Seeds "The Seed is today's Spinning Wheel" (Vandana Shiva) Patenting & Genetic Engineering are major threats Seed saving & recuperation of local species therefore crucial Also very good business!
Seed Banks : we have a great Seed Saving Manual in the e-Book! Collecting Heritage Varieties & Locally adapted crops very important for your bioregion Seed Banks Learn how to collect your own seeds & how to support your nearest Seed Bank

Plant Reproduction I : Plant Reproduction I Sexual Reproduction (Seeds, some spores) - involves genetic re-combination Hybrids & non-hybrids > seed propagation Hybridization: a naturally occurring genetic process where individuals from two genetically distinct populations mate
Plant Reproduction II : Plant Reproduction II Asexual Reproduction - exactly same plant as 'mother' plant There is a great number of methods for this, see Plant Propagation section under Biodiversity in e-Book! Cuttings Layering Division Budding/grafting << some of the most commonly used ways there are lots!
PowerPoint Presentation :
Layering : Layering Many plants propagate themselves this way in nature: stems produce roots when they come into contact with the ground. Eg. Strawberries (below) Water stress minimized Nutrients high Natural or assisted When root formed can detach from mother plant can't go wrong :)
PowerPoint Presentation : Auxins - when plant is wounded > alter nature of cell division in cambium layer > embryonic root tissue New year's growth Stem snaps scratch to cambium Rosemary Sage some Basils Mints Geraniums ... Cuttings
Budding & Grafting : Budding & Grafting Lots of fruit-trees are reproduced this way, can use different root-stock. Also roses & vines for eg. (below) Budding when bark 'slips' (growing season) apples, peaches, pears Grafting when dormant (winter) Must match cambium layers
Marcotting : Marcotting Like with budding & grafting, used for fruit trees & bushes also because fruit quicker than by seed. Also roses & vines for eg. (below) Woody stems 1-2cm Bark cut off section When enough roots appear Cut off mother plant & potted Also low-risk, like layering

PowerPoint Presentation : many types of nursery tree nurseries especially VITAL & easy
the Green Belt Movement : the Green Belt Movement Through creating their own tree nurseries – at least 6,000 throughout Kenya – and planting trees, women began to control the supply of their own firewood, an enormous power shift that also freed up time for other pursuits.
