Are Micro-Organisms slaves for Human-being??

You just said it can.

soon there will be marches for micro organism rights

I think that micro organisms have been using US for a long time, so what if we get some use out of them!

Interesting. I'll have to do some research. We've been using micro-organisms
for a long time. I don't know all applications, but for at least 10-15 yrs we've
been using them to metabolise petroleum products in oil spills. Yes, there are
bacteria that digest oil.

We've used certain kinds of viruses, that have been genetically altered to
render them harmless, in genetic engineering to deliver altered genetic
material to cells. They act as carriers because they basically inject the
dna, or rna depending on applications, into a particular kind of cell.

Are they slaves for us?

I guess it depends on how you want to look at it. Being a slave sort of
implies having one's free will taken away. Good luck arguing bacteria and
viruses have free will.

The natural order is symbiosis. Different living organisms co-existing and
"using" each other for their own purposes which is basically to survive
and procreate.

Feeling bad for micro-organisms? How about when they invade us, as
they always do every minute of the day, and cause all the various diseases
we get?

Eat some tainted food and think about them enslaving you when you're
spending an entire day either on the toilet or bent over it.

Hope that helps!
