The cotton pillowcase is infused with silver ions, which basically S&D (seek and destroy, for those of you not in the military-lingo know) bacteria before they have a chance to multiply and render your pillowcase a three-ring circus of vileness.
Habitat destruction is the process in which natural habitat is rendered functionally unable to support the species present. In this process, the organisms that previously used the site are displaced or destroyed, reducing biodiversity.
This type of habitat destruction is called fragmentation. Fragmentation is when the habitat is broken up into pieces or fragments. A road could cut the area of the habitat in half and cause the species a lack of options in which to mate with. This type of destruction can also cause a lack of resources for food.
