re: #263 Altermite
Zombie, that is not what “nonbiodegradable” means. I don’t know where you got that definition.
There are many nonbidegradable products that are toxic to the biosphere.
Please explain then.
If something biodegrades, it breaks down into its constituent components. If it’s nonbiodegradable, it doesn’t. (Under natural conditions.) If a nonbidegradable product is toxic to the biosphere, then it isn’t truly nonbiodegradable.
If it’s leaching toxins or chemicals, then it’s degrading, hence is biodegradable.
Perhaps there are other definitions?
