Threats to Seagrasses: 1  Natural threats to seagrasses include storms, climate changes such as floods and droughts affecting water salinity, disruption of seagrasses by small predators as they search for food, and grazing by animals such as sea turtles and manatees.eagrasses may be confused with seaweeds (marine algae), but they are not. Seagrasses are vascular plants and reproduce by flowering and producing seeds. Marine algae are classified as protists (which also includes protozoans, prokaryotes, fungi and sponges), are relatively simple and reproduce using spores.
According to Defenders of Wildlife, a wildlife charity organization, sea otters are endangered because they were nearly hunted to extinction in the 1700s and 1800s. Sea otters once numbered in the hundreds of thousands, but fur traders hunted them in large numbers and, consequently, reduced their population size. The International Fur Seal Treaty of 1911, the Marine Mammal Protection Act and the Endangered Species Act of 1977 helped stop the sea otter population from dwindling. However, the sea otter population has been slow to recover. In addition to oil spills, sea otters also face other human threats.
