Ever since life formed on Earth, numerous species of plants and animals have come and gone, and the process of extinction has been occurring long before the existence of humans and is somehow a natural process. Generally, through specialization, a new species develop at the same rate that other species become extinct. But, due to the growth of human population plus factors like pollution, deforestation, over hunting, loss of habitat and environmental changes, species extinction is now occurring at a rate that far outstrips the specialization rate. Humans are selfish creatures, but they dont understand that every extinction diminishes the
complexity and biodiversity of life on Earth. We should understand that if enough of these living connections are broken, then our whole ecosystem could fail to balance and could be altered forever. See also P P P P P P P P P PP We are currently experiencing a greatly accelerated rate of extinction for both flora and fauna and by 2050; about 40 percent of the worlds species could be extinct. It is hard to believe that we are in the worlds 6th mass extinction of flora and fauna since the dinosaurs left the town 65 million years ago. Imagine going to a zoo ten years from now with your children. You bump into an empty jungle themed cage that says, This used to be home to some of the last surviving Lions in existence; apparently, these creatures are known to be extinct. But you might be thinking that why should I care about something without a brain and a name I cannot pronounce?
Well, the thing is, each living organism whether it is a plant, animal, fungi or micro-organism, possesses a unique genetic code that has evolved since the beginning of life on Earth. And if they are lost, it cannot be recovered. You might never know when we need a specific plant or fungi to cure a disease. As history speaks, many plants and other organisms have helped humans to create drugs and treat diseases. This impact to humans includes ecological, medicinal, agricultural and commercial recreation. Life-saving drugs and foods are derived from plants and animals, and humans depend on ecosystems such as grasslands, forests and coastal inlets to clean their water, purify their air and food supply. When species become endangered, these ecosystems are most affected, and they will begin to unravel. A study estimates that even losing a one plant species can trigger the loss of up to 25-35 insects, plants and animal species. It is compulsory that word take action now, and many Acts have been authorized by countries to save these endangered species, so we have a chance to save some of the species of flora and fauna. The diversity of flora and fauna helps to maintain a stable ecosystem, and if a species is lost, you never know what the consequences will be. People must be educated about the risks and dangers of sustaining in the series of action that leads to this problem.
Will we lose an important phenomenon that could cure AIDS/cancer? Or life on Earth will collapse? As you may or may not remember I am going to focus my civic issues blog on critically endangered species and why should anyone care? Why should anyone care about animals that are going extinct due to habitat loss and poaching? I want to explore these animals and how there extinction could potentially affect humans and the world we live in. For my first post I am going to be talking about the Black Rhino. Recently I have seen posts being shared on facebook saying that the African Rhino is officially extinct in the wild. That is not true at this point, but they are still critically endangered. Black rhinos used to be found throughout a fair portion of Africa. Now they are in fragmented populations in Namibia, Kenya, Tanzania, Zimbabwe, South Africa, Cameroon, Swaziland and Malawi. The start to the decline in there population began with European hunters and has continued. Habitat loss has contributed to the loss of population, but poaching is the main cause of the declining population. In just 22 short years between 1970 and 1992, 96% of the Black Rhino population in Africa was killed. And the numbers arenБt really getting better today. The demand for rhino horn is rising. Many people in Asian countries believe in folk remedies that contain rhino horn. But rhino horn is just keratin, the same type of protein that makes up our hair, skin and nails.
Conservation efforts are being made, but despite them loses to poaching in places like South Africa are still increasing. In 2014, there was a 21% increase of rhinos poached in South Africa as compared to the previous year. Rhinos are one of the oldest groups of mammals in the world and humans are currently hunting them to extinction. Now the question is why should we care? I know IБve asked myself that, what would really happen if rhinoБs and other animals go extinct due to human expansion and intervention? There isnБt an answer to this question because biodiversity and ecosystems are very complex. But most conservation scientists and the like assume there will be an affect. All species are constantly interacting and having an impact on their environment and it is very difficult to say what exactly will happen if a species impact is removed. б But we can look at the possible effects and what has happened when other species have become extinct in certain habitats. The most obvious impact of any species becoming instinct is the impact it would have on the habitat. Ecosystems and the species in them have intentionally involved keeping each other in balance and removing or adding something from an ecosystem will easily throw the balance off. б For example, when wolves were exterminated in western America there was an increase in the elk population which led to more pressure on their foods sources.
It is impossible to know what exactly the effect of rhinoБs becoming extinct will have on the environment but it will most likely cause some sort of cascading effect. The impact on many human lives from black rhinoБs extinction could also be great. Tourism in the countries where black rhinos live is a very important part of their economies. Many people go to places like South Africa, Namibia and Kenya to see the wildlife specifically animals live the Бbig 5Б, rhinos, elephant, lions, leopards and buffalo. If the populations of rhinos and the rest of these animals continue to decline it could seriously hurt the tourism industry and the economies of African countries. Tourism supports nearly one million jobs in South Africa, Kenya, Namibia and Zimbabwe. And in Namibia the tourism industry indirectly supports 19% of the jobs. So we have to think what could happen if one of the main reasons people go to these places goes extinct. What could it do to the environment and the economies of these countries? These consequences may not necessarily be Бclose to homeБ for us, but they will greatly effect a large part of our world and the people in it. Now the question is what can we do to save the rhinoБs and there is not a clear cut answer to that either. Ideally people would start realizing the consequences for their actions and stop hunting them but right now the market and the potential monetary value for rhino horns is just too large.
