In examining a cell using the electron microscope, you see a structure that is composed of two membranes, contains numerous pores, and appears to be connected to a network of membrane-enclosed compartments. The structure you are observing is most likely the nuclear envelope.

Nuclear Envelope

Explanation:

The endomembrane system includes the nuclear envelope, the endoplasmic reticulum, Golgi mechanical assembly, lysosomes, vesicles, just as the plasma layerThese cell parts cooperate to alter, bundle, tag, and transport layer lipids and proteins The nuclear envelope is a double membrane, implying that there are two lipid bilayersThe nuclear lamina, a netlike cluster of protein filaments, associates the layers of the nuclear envelope

Iwould say overuse ( but not 100% sure ) in the u.s. we tend to overuse water by leaving it running, throwing it away, taking long showers, etc.
