If you care about the world of nature, including the plants and animals that evolved along with us, you surely understand that the world situation has become unbearable (and unsustainable) for the future of the planet´s biota. We cannot stand passively by while populations and ecosystems continue to degrade, resulting in thousands of species being at the brink of extinction or tipped over the edge. We should never accept the terrible course that the natural world is taking today when the only end result seems to be the eradication of much of the world´s living organisms.
I have spent the last forty years studying primates, mostly in their natural habitats in Colombia, and I have been privileged to know many species of plants and animals in an entirely natural state. Yet more and more, I am aware of the increasing destruction of natural habitats and the threats that continue to increase, generated by us human beings. Many of these threats are due, I think, to the ignorance that many humans have about the natural world. Humans are so taken up by themselves that they often spend no time at all thinking about the other living things around us. I know that millions of humans are focused on themselves because of their poverty and the necessity that they have to survive, leaving little energy to worry about other organisms. Many other millions of people and much human development are motivated by greed and by laziness and do not appreciate what they are helping to destroy. Many have no concept of how we are connected to the natural world and the horrible, desolate life that we will reap if the natural world disappears.
About 48% of the world primates and 39% of the approximately 150 species of neotropical primates are threatened with extinction, due mostly to habitat destruction (Mittermeier 2013). A new species of monkey that we discovered in the Colombian department of Caquetá in 2014 may have only a few hundred individuals left in its total population because of intensive forest conversion into cattle pastures (see Colombian Primates that are Critically Endangered on this website). Other primate species in the world contain just a few dozen individuals; others like our Colombian titi of Caquetá only a few hundred. All nonhuman primates are threatened by habitat loss caused by human activities. One of the principal reasons that we humans don´t establish and protect populations of other animals and plants is because of our ignorance and our lack of caring. However, overpopulation is also enormous pressure on the natural world. It is worthwhile realizing that the most numerous species of animals on the planet are rats and human beings. Do we need to be competing with rats for dominance?
I, as a Colombo-American, do care about all Colombian and neotropical primates, and I would hope that you who read this might care as well. Colombia has about 38 (or so) primate species. The number isn´t yet certain because of the different ways that some of us define species and because we don´t have enough genetic information to allow us to say definitely that some populations are, indeed, species (see Colombian Primate Taxonomy in this webpage). Also, there still might be some Colombian species that haven´t as yet been recognized. So we need to do a lot more work on identifying what are and are not species. But even more critical, we urgently need to guarantee the survival of all these primate species as well as the multitude of other species of plants and animals that exist in Colombia.
On this website, you will find quite a lot of material that I have published that will educate you a little as to what I have discovered during my research alone and with other Colombians. There are a couple of my books available on this website that can be downloaded as pdf and information about my newest publications. I would be happy to hear from anyone who wants to discuss this information or any other aspects of conservation and primatology, so drop me a line (in Spanish or English). From time to time, I will publish my comments on pertinent subjects that might be of interest to you.
