* Danaus plexippus *

It may be the most familiar North American butterfly. Butterflies , help pollinate plants, making them a vital contributor to crop growth and food production.
Several factors have contributed to the monarch's decline; climate change, loss of reproductive habitats, predators, and deforestation in Mexico’s forests, have all impacted the butterfly’s migration pattern and habitat. The most significant threat is the decline in milkweed, the plant where monarchs lay their eggs, and that serves as the only food source for caterpillars.
Their colonies in Mexico now occupy the smallest area since records began in 1993.

S. Name: Trichechus manatus
Cause of extinction: It is estimated that the population of the Antillean manatee was several thousand when the Europeans came to what we know as the United States. Unfortunately the meat was considered as exquisite, besides the fact that being dry lasts about 1 month and if room can last up to 3 months (True, 1884). The exploitation of manatees also occurred for oil and skin. More directly man has contributed in his decline by altering the habitat of the species by pouring waste and waste water into it, as well as by dredging and filling areas.

Extinct in 2008. The case of the baiji or Chinese river dolphin is the best example that a delayed reaction is not enough. Overfishing and dam construction decimated the population of this type of dolphin, characterized by its elongated snout, until in 1979 the Chinese government declared endangered. In 1983 hunting was outlawed and the species was gradually decreasing until only 23 specimens were found in 2007. In 2008 it was officially declared extinct.

Balaenoptera musculus

The blue whales have been massively hunted since the beginning of the XX century for their oil, and they've managed only a minor recovery since then. Humans have made that process even slower with these threats:

- Many are injured or die each year from impacts with large ships, as well as becoming trapped or entangled in fishing gear.

- The ever-increasing amount of ocean noise, including sonar make it harder for them to communicate, also interfering with foraging behavior.

- The accumulation of polychlorinated biphenyl (PCB) chemicals within the whale's body due to humans.

- With global warming causing glaciers and permafrost to melt rapidly and allowing a large amount of fresh water to flow into the oceans, there could be a disruption in the thermohaline circulation affecting their migratory patterns.

- The change in ocean temperature would also affect the blue whale's food supply.
