The investigation goes on to conclude that if protection against the manatees is not more heavily enforced, “there won’t be enough manatees within 100 years to sustain their population”.Many humans recognize that change is needed to protect a great number of plants and animals from becoming endangered, or even worse, extinct.
As such, those animals that have been designated are afforded protection under conservation and preservation laws.
species of plants as either threatened or endangered.
Take a look at the image that illustrates examples of what people have done that put plant and animal lives at risk.
The burning of fossil fuels, which supplies much of our electricity, causes pollutants like sulfur dioxide and nitrogen oxide to go into the air where they join water droplets in the clouds.
Other causes of human-related manatee mortalities include being crushed and/or drowned in canal locks and flood control structures; ingestion of fish hooks, litter and monofilament line; entanglement in crab trap lines; and vandalism.
Ultimately, however, loss of habitat is the most serious threat facing manatees today.
The precipitation that falls becomes acid rain, which gets into our land and water systems, affecting everything in that area.
An invasive species is one that is not native to an area.
Although the manatee is strictly an herbivore and has no known natural enemies, collisions with watercraft in their natural environment coupled with death via problems with pollution and habitat decimation have drastically reduced the number of manatees that currently exist.
Aside from genetic difficulties, scientists break down the causes of manatee deaths into six different categories: Most human-related manatee mortalities occur from collisions with watercraft.
