Answer to Question 1

One: The product may degrade before its intended function is completed. Two: The product may degrade into components which are polluting.

Answer to Question 2

Snap-fit joints depend on the ability of the plastic material to deform slightly without breakage or permanent deformation. If the plastic part is so stiff that small amounts of movement will cause it to break, snap fits cannot be used. This breakage might also occur in the mold is a snap fit depends on an undercut in the part that must be stripped out of the mold.
