It is unlikely that death rates will fall as rapidly in the next few decades as in the recent past in either developed or developing countries.
One type of weathering is man made weathering. (For example) Humans may carve a rock or mine for minerals. Another type is natural weathering. This is when a river may push a rock or lighting may scratch a tree. That weathering is naturally occurring. Hope that helped!
