Is this a question or answer..I can't understand
Mucous membranes line the passageways that open to the exterior of the body, including those of the respiratory, digestive, reproductive, and urinary systems in the body.
A mucous membrane or mucosa is a membrane that lines various cavities in the body of an organism and covers the surface of internal organs. It consists of one or more layers of epithelial cells overlying a layer of loose connective tissue.
It is mostly of endodermal origin and is continuous with the skin at body openings such as the eyes, eyelids, ears, inside the nose, inside the mouth, lips, the genital areas, the urethral opening and the anus. Some mucous membranes secrete mucus, a thick protective fluid. The function of the membrane is to stop pathogens and dirt from entering the body and to prevent bodily tissues from becoming dehydrated.
One of its functions is to keep the tissue moist (for example in the respiratory tract, including the mouth and nose). It also plays a role in absorbing and transforming nutrients.
Mucous membranes also protect the body from itself. For instance, mucosa in the stomach protects it from stomach acid and mucosa lining the bladder protects the underlying tissue from urine. In the uterus, the mucous membrane is called the endometrium, and it swells each month and is then eliminated during menstruation.

Answer:
Humans have destroyed and modified various locations, such as forests, jungles, oceans. They begin to modify an environment in order to build new infrastructures, like buildings, factories, or even communities.
Explanation:
The reason for this is because they want to get as much resources for economic purposes, like for example mines, touristic places, factories. At first, this interaction affects the environment more, because of the loss of species or resources due to the human activity. Then, after this, it will affect the human, because of the lack of resources and global contamination caused by the environment being destroyed or modified.
