Answer: Human activities is the most likely reason for it
Explanation:
A species is said to be extinct when there are no more individuals in that group, i.e, when a certain species of living beings definitively disappears from the planet. Since the emergence of the Earth, several species have disappeared and these extinctions happened for several reasons. Among the reasons, there are those caused by forces of nature such as earthquakes, volcanoes, changes in the planet's climate, such as glaciations - periods when certain parts of the planet were covered with ice, which caused the death of many beings that lived in those environments. However, in the modern society in which we live, the human being has been the biggest cause of the extinction of species.
The big problem is that the action of human beings has caused great environmental changes, altering the planet's climate, destroying habitats of several species. Human activities have a greater impact on terrestrial and freshwater ecosystems and for this reason the rate of extinction of terrestrial and freshwater species is higher than the rate of extinction of marine species
