Estimates suggest that Earth is currently losing species at a rate of approximately 100 to 1,000 times higher than the natural background rate, with many scientists warning that we're experiencing the sixth mass extinction. The exact number can vary widely depending on the source, but a commonly cited figure is around 100 to 200 species per day, translating to roughly 36,500 to 73,000 species per year. Therefore, none of the provided options accurately capture the scale of species loss per year, but option D (121) is the closest to the lower estimates, albeit still significantly underestimating the actual rate of loss.
