Yes rivers can self purify but NO we should not pollute. It doesnt make things better
Any resource that is not renewable, or self-renewing, cannot be replaced (at least, not in our lifetime).Fossil fuels (coal, oil and natural gas) are a good example, as they took hundreds of millions of years to turn from organic material to fuel.
Rear calipers are self adjusting. lower piston has an adjuster in centre thet takes an 8mm allen key. This can stick in when renewing pads and will not self adjust unless freed off
There are two types of fertilizer, artificial (man made) and natural (rotting plant material, animal waste and nitrogen fixing bacteria). Natural fertilizers are "self renewing" if used properly and therefore "self replace".
There is a field of study call self-purification, that occurs in streams, rivers and ponds. The biological factors that enhance self-purification are the friendly bacteria that are part of the natural eco-system.
That depends on whether the lease is self-renewing, and, if so, how much notice is required to cancel the renewal.
