INTRODUCTION There have been 5 mass extinctions in the past, of which the last one best known to man, the Cretaceous-Tertiary mass extinction which caused the disappearance of the dinosaurs. Although the last one occurred 65 million years ago, something that represents this mass extinction phenomenon is underway in our time. While in the past mass extinctions were caused by natural forces, and asteroids, climate change and sea level changes were thought to be the culprit, this time the actor behind it is not natural, and it is us humans. It might occur to many that the current trend towards animal extinction has no consequences for us, but in reality this is not true. Many of the endangered species are important to us. In this article, using as main headlines examples of some neglected critically endangered species, I will examine the different forms of human activities that have led to their losses and, more importantly, how these losses might have impacted about us. THE NEW EXTINCTION Definition of mass extinction by David Jablonski, American professor of geophysical sciences at the University of Chicago is "substantial losses of biodiversity that occur rapidly and are global in scope" (Kolbert, 2014). But how exactly could current species loss actually be relative to the above definition? Although the exact number of species on earth is too complicated to calculate, researchers have tried to find some ways to estimate the numbers. The extinction rate currently estimated by experts should be between 1000 and 10000 times higher than the rate if man had not been present (background rate), reflecting the damage caused by human activities that is unimaginable and indeed very serious. (Thomas et al., 2004) For…half of the paper…we will secure what we have today. According to National Geographic News, “There are more than 20,000 plants and animals that are on the verge of disappearing forever.” (National Geographic News, 2005) Animals in danger of extinction are not a myth, they are real and they are happening. As the world becomes increasingly interconnected and globalized, trade and economic issues have become the top agenda for most countries, where animals and the environment have been ignored, and everything that benefits us even though harms the latter is not considered wrong. In my opinion, despite knowing the impact that animal extinction has on us humans, we should not let animals that have lived for millions of years go extinct just because of us and our selfishness. We need to start thinking about the earth as a whole, sharing it with all animals and not with humans as the dominant group..
