what is the first animal to go extinct? With their penchant for hunting, habitat destruction and the release of invasive species, humans undid millions of years of evolution, and swiftly removed this bird from the face of the Earth.

why do you think species become extinct?
The main modern causes of extinction are the loss and degradation of habitat (mainly deforestation), over exploitation (hunting, overfishing), invasive species, climate change, and nitrogen pollution.
how to find extinction coefficient given a graph?
εbc, where A is the absorbance, ε is the molar extinction coefficient, b is the path length of the cuvette and c is the concentration. Thus, the molar extinction coefficient can be obtained by calculating the slope of the absorbance vs. concentration plot.
how can pollution lead to extinction?
Air pollutants can poison wildlife through the disruption of endocrine function, organ injury, increased vulnerability to stresses and diseases, lower reproductive success, and possible death.
what animals have scientists brought back from extinction?
Here are five times over the past 10 years when scientists brought back the living dead — and one animal that may reemerge in the future.
what would happen if elk went extinct?
Animals such as Mountain Lions, Gray Wolves, Bobcats, and Coyotes would be affected. People see this as not important. If this were to happen, another species would have to fill its ecological niche.

What are the natural causes of species extinction?
Natural causes for extinction include the following: asteroids, acid rain, volcanic eruptions, earthquakes, climatic heating or cooling, changes in sea level or currents, cosmic radiation, predation and disease, and spread of invasive species.
What is the primary cause of the decline of frogs and salamanders?
Habitat loss, disease and climate change are thought to be responsible for the drastic decline in populations in recent years.
What are threats to cheetahs?

What wiped out megafauna?
Research suggests extreme climates, not humans, wiped them out. Human activities and population growth have wrought much destruction to life on Earth. But when it comes to megafauna extinctions, evidence suggests we may be off the hook – rather, the major culprit could be climate change.
Does pollution cause extinction?
Climate change and pollution continue to rise as threats, with severe weather, changing ecosystems and rising temperatures responsible for 33 animal extinctions, while pollution is responsible for 37 extinctions to date, new data shows.
Are elk protected in the US?
“Unlike the privately owned cattle that have unrestrained access to water sources in this area, the elk are protected by federal law that requires the Park Service to ‘conserve’ them for the public and future generations,” said Katherine Meyer, director of Harvard Law School’s Animal Law & Policy Clinic.
