Like all living things, parasites have two main purposes: to survive and to procreate. A parasite probably does not conceive itself as being a parasite. Only the host may feel the imposition. Some parasites, of course, cause the death of their hosts, one way or another. There are those who see man as a parasite gradually dooming the host, Earth, as a place on which to survive. Conservation, anyone?
Melissa - my understanding is different. I agree that viruses are on the edge of living/non-living. But, if alive, they fit the definition of animal - they don't photosynthesize, and live off other living things. But definitions change over time.
hahaha! Not at all, but it does seem so, right? Before medicine arrived the population was something like 2 billion and then it shot up exponentially all because of medicine. So ye probably for population control
A parasite is an Earth-borne life-form that can be an animal, a plant, a fungus, a bacteria - or even a virus (which is not even technically alive according to the standard text-book definition of 'alive/living').
And, just like all other life-forms, its sole goal (or its purpose, as it were) is to survive, thrive, reproduce, and gradually evolve, genetically.
Despite of how it might seem, a parasite's purpose is NEVER to kill or harm the host!
You are absolutely right. I was thinking my answer over and came to that same conclusion. What makes a parasite 'parasitic' is that it doesn't concern itself with the well-being of the host. The primary drive is to procreate at any cost...
Putting together what I see here: Purpose always is in a context.
The parasite's own purpose is to survive, even at a cost to its host.
The ecosystem creates a purpose for parasites - prevention of over-population by a species that is not being regulated by a carnivore above it on the food chain.
Human civilization, as a whole, is currently operating in a parasitic way in relation to Gaia, the living planet Earth. This is because we think and live on a survival level. Each human being who learns to think on a level and live of cooperation (commonly called Love) creates an expression of human life that is not parasitic, but symbiotic. If all of humankind learns to do this, then the resulting Gaia-human system will be a whole greater than the sum of its parts. That will be beautiful when it happens. Till the, we can each make it happen in our own lives.
A brain is not the issue. Epistemologically, purpose is related to function, and functional result. Any system can be seen as having a purpose. A parasite is a system within a larger pair-system and an even larger ecosystem. 3 levels of purpose.
Do you believe in overpopulation and/or population control?Do you believe there is a humane solution viable of human beings own free will? Many believe and have evidence that certain organized groups impose population...
What does it feel like to do a parasite cleanse?I'm going to do a parasite cleanse to kick start my chelation but wondered what 'symptoms' it created. Am I likely to feel rough and need to stay in for a few days? I'll...
Multiple arguments have been presented in various forums (inside and outside of HubPages) to argue for the existence of God. They run the gamut from the Cosmological ( Efficient Causality, Contingency,...
