The current rate of species extinction in the world is estimated to 100-1000 times higher (spread across all types of life) than the background extinction rate (average over very-long time-scales), primarily as a result of modern/industrial human activity.
Some groups are experiencing much higher rates even than that though — amphibians, for example, are currently going extinct roughly ~45,000 times faster than the background extinction rate. Most/many amphibian species are expected to go extinct at some point in the foreseeable future — without large changes to the current trajectory occurring. (There are notable exceptions to this.)
Despite the growing rates of extinctions, research has shown that public interest and concern has actually been diminishing greatly over the last few decades. (Perhaps as backlash against the tactics/hypocrisy of many “environmental” organizations? Perhaps because less and less people grow up in rural areas and spend time in the “wild”? Perhaps because entertainment consumption, drug-use, and obesity, has all skyrocketed in recent decades? Hard to say…)
Many researchers have estimated that at current rates of extinction, up to one-half of all the currently existing plant + animal species in the world will be extinct by the year 2100.
