Manatee Conservation Status - Sources of Danger

Sources of Danger

Various human activities threaten manatee populations, and activists working to save the species aggressively protest these actions. Fishing nets and lines can cause injuries to manatees that often lead to serious infections. Many manatee deaths are the result of collisions with boats when the mammals are surfacing for air. They are not fast enough to elude the boat propellers, and thus suffer from fatal gashes. Additionally, the recent increase in coastal development has severely affected manatee habitats. The habitats themselves have been destroyed as residential and commercial development has occurred along seagrass beds, mangroves, and salt marshes where manatees live. Pollution in these areas may also have an effect on manatee mortality, as chemicals introduced into their habitats lead to impaired immune systems. The fact that manatees tend to gather in the warm water outflows of power plants furthers the likelihood of the spread of disease. Humans are the only life that endangers manatees.

Famous quotes containing the words sources of, sources and/or danger:

    My profession brought me in contact with various minds. Earnest, serious discussion on the condition of woman enlivened my business room; failures of banks, no dividends from railroads, defalcations of all kinds, public and private, widows and orphans and unmarried women beggared by the dishonesty, or the mismanagement of men, were fruitful sources of conversation; confidence in man as a protector was evidently losing ground, and women were beginning to see that they must protect themselves.
    Harriot K. Hunt (1805–1875)

    On board ship there are many sources of joy of which the land knows nothing. You may flirt and dance at sixty; and if you are awkward in the turn of a valse, you may put it down to the motion of the ship. You need wear no gloves, and may drink your soda-and-brandy without being ashamed of it.
    Anthony Trollope (1815–1882)

    To an immature nature essentially honest and humane, forewarning intimations of subtler danger from one’s kind come tardily if at all.
    Herman Melville (1819–1891)
