The Mexican grizzly bear had the temperate grasslands and the rich mountainous pine forests of northern Mexico as its home. It was one of the largest and heaviest mammals in the biodiverse country. Although its main diet consisted of the plant, fruits, and insects of the forest, it occasionally considered small mammals and carrion. The fate of this bear changed when farmers began seeing the bear as a disturbance because it hunted their cattle. The bear was trapped, shot and poisoned. Although it found a little safety in Mexico’s isolated mountains of Cerro Santa Clara, Cerro Campana, and Sierra del Nido, its population dropped to 30 by 1960. The bear continued to be hunted despite its protected status. Just four years later, in 1964, the lovely Mexican grizzly bear was considered as extinct.
Oryzomys nelsoni was a large rodent distinguished by its particularly long tail, large incisors and robust skull. This reddish to yellowish above and mostly white below animal inhabited the María Madre Island of Mexico feeding on plant material and small animals. After its discovery in 1897, it has never been recorded again. It is now considered extinct. The introduction of black rats to María Madre may have contributed to its extinction.
The Socorro dove only existed on the Socorro Island off the west coast of Mexico. Feeding by feral cats, high rate of understorey grazing by sheep, and human hunting most likely contributed to its drop in numbers. Although there are around 100 of the birds in captivity for conservation, it was last sighted in its natural habitat in 1972.
What do we learn from the Extinct Animals From Mexico?
Mexico is recognized as one of the most biodiverse countries in the world. It is home to about 10% of all known species. From tropical jungles in the Yucatan peninsula and Chiapas to its coral reefs in the Caribbean Sea and its deserts and prairies in the north, Mexico boasts incredibly diverse ecosystems. But the rich wildlife of the country has been seriously threatened by human encroachment and climate change.
The Mexican grizzly bear, Oryzomys nelsoni, and Socorro dove are just a few examples of the extinct animals from Mexico. In past years, dozens of animals, including several sea creatures, birds, mammals, and amphibians, have been driven to extinction by humans activities. Poaching, habitat destruction, and pollution have led to the loss of many species. The preservation of species is essential to our existence. Scientists that every part of the world where life exists provides humans with about $33 trillion worth of various services each year. For instance, we depend on other species for our foods and shelter. Several of our medications like those used for high blood pressure are derived from little unknown species.
Scientists predict that we might be on the brink of yet another mass extinction. We have less and less time to waste. We can start with changing the way we treat and care for the planet and most importantly change our habits of consumption.
