Lt ripley thank you for another thoughtful and detailed analysis of my post. I agree with a lot of what you say but perhaps have a different slant/perspective /emphasis on some viewpoints. For example, I would say that worms do not have a purpose, because purpose implies intent. We attribute the worms role as a purpose, but the worm cannot. It is simply an evolutionary response/fact of life. The worm cannot chose any other "purpose". Only sentient self aware beings can do this. Thus the worm has a role, but only a human can create a purpose.(I appreciate this may be playing semantics,) but only through understanding my definition of purpose, can you understand my viewpoint on it.
This passage illustrates our different perspectives on life, which I am sure we have both come to honestly, and for each of us are equally valid. We, perhaps, cannot accept each other's viewpoints because our life experiences (which create our viewpoints )have been different.
As stated before, i do plan and visualise my life. As with sports training, this increases the possibility of successfully acheiving your goals. Sometimes one is smitten from left field. I never intended to fall in love with a first cousin, who was nearly 10 years older than me. Once this happened it required some radical readjustments of family and social values/ expectations. But we worked on this and achieved it.
My family was very poor. I gained an education dept scholarship for my last 3 years of high school and got to uni because i was bonded to the ed dept. This meant they paid my uni expenses, but I had to work anywhere they choose for my first four years. Every day, of every holiday, I worked as a cleaner and groundsman at my high school from the age of 13 to 17 This gave me a look at another aspect of life, a number of different skills, and an appreciation for the value of hard physical work. All my pay was divided between my parents, to help out, and a bank account for when I went 400 miles away to uni and teachers college.
I still have the same zeal for teaching. Given that I have to retire in a few years, i have already said to the principal that I would like to come back and teach on a voluntary basis.
I accept that life can make minor variations in your plans and purposes, but my experience is that we are indeed masters of our own fates and that every decision we make, large or small, leads us towards, or away, from that goal/purpose. If we understand our purpose, and the right decisions required, we can acheive the great majority of anything we set out to do. Being poor might make it harder, coming fom an african or south american country harder still, but no one should simply give up because it is too hard, or because they believe their fate/future is in any way predestined.
so we will have to agree to disagree.
yet purpose doesn't always come with intent. I became an artist with intent , but I didn't pull that purpose out of a hat , I was always gifted and not by my own doing. it was natural to me.
you may not think a worm has purpose , but they enrich the earth with thier waste. without them we'd starve.
The major benefits of earthworm activities to soil fertility can be summarized as:
Biological. The earthworm is essential to composting; the process of converting dead organic matter into rich humus, a medium vital to the growth of healthy plants, and thus ensuring the continuance of the cycle of fertility. This is achieved by the worm's actions of pulling down below any organic matter deposited on the soil surface (eg, leaf fall, manure, etc) either for food or when it needs to plug its burrow. Once in the burrow, the worm will shred the leaf and partially digest it, then mingle it with the earth by saturating it with intestinal secretions. Worm casts (see below) can contain 40% more humus than the top 6" of soil in which the worm is living.
Chemical. As well as dead organic matter, the earthworm also ingests any other soil particles that are small enough—including stones up to 1/20 of an inch (1.25mm) across—into its 'crop' wherein minute fragments of grit grind everything into a fine paste which is then digested in the stomach. When the worm excretes this in the form of casts which are deposited on the surface or deeper in the soil, a perfectly balanced selection of minerals and plant nutrients is made available in an accessible form. Investigations in the US show that fresh earthworm casts are 5 times richer in available nitrogen, 7 times richer in available phosphates and 11 times richer in available potash than the surrounding upper 6 inches (150 mm) of soil. In conditions where there is plenty of available humus, the weight of casts produced may be greater than 4.5 kg (10 lb) per worm per year, in itself an indicator of why it pays the gardener or farmer to keep worm populations high.
Physical. By its burrowing actions, the earthworm is of great value in keeping the soil structure open, creating a multitude of channels which allow the processes of both aeration and drainage to occur. Permaculture co-founder Bill Mollison points out that by sliding in their tunnels, earthworms "act as an innumerable army of pistons pumping air in and out of the soils on a 24 hour cycle (more rapidly at night)" [2]. Thus the earthworm not only creates passages for air and water to traverse, but is itself a vital component in the living biosystem that is healthy soil.
See Bioturbation.
The earthworm's existence can not be taken for granted. Dr. W. E. Shewell Cooper observed "tremendous numerical differences between adjacent gardens" (Soil, Humus And Health), and worm populations are affected by a host of environmental factors, many of which can be influenced by good management practices on the part of the gardener or farmer.
Darwin estimated that arable land contains up to 53,000 worms per acre (13/m²), but more recent research from Rothamsted Experimental Station has produced figures suggesting that even poor soil may support 250,000/acre (62/m²), whilst rich fertile farmland may have up to 1,750,000/acre (432/m²), meaning that the weight of earthworms beneath the farmer's soil could be greater than that of his livestock upon its surface. One thing is certain however: rich, fertile soil that is cared for organically and well-fed and husbanded by its steward will reap its reward in a healthy worm population, whilst denuded, overworked, and eroded land will almost certainly contain fewer, scrawny, undernourished specimens.
http://en.wikipedia.org/wiki/Earthworm#Benefitsyet it has no intent. as someone once said to me about one of the panhandelers off our freeway ( she was a known junkie) ' even she has a purpose . it may be to keep someone off drugs as an example.' I hadn't thought of that before.
