Essay / 6e Mass Extinction Essay - 2004
Introduction:Our Earth has experienced five mass extinctions caused by natural disasters such as comet or meteor showers impacting and destroying sections of the Earth, the displacement of continents caused by changes in platonic position. plates and climate changes such as the end of the ice age which caused the disappearance of certain species. These mass extinctions occurred over a long period of thousands of years, not the concentrated 200 years of drastic geological and biological changes that have led scientists to believe we are currently experiencing the 6th mass extinction. Annenberg Learner (2013) states that unlike previous mass extinctions which were due to natural phenomena, the 6th mass extinction is due to human influence. We have helped harm species and their habits with factors such as deforestation, overfishing, poaching and factory pollution. Our carbon footprint has caused an upheaval in our ozone layer and a greenhouse effect commonly known as global warming. All of these problems in our environment threaten the Earth's biodiversity and increase the number of endangered and already extinct species. Despite the United Nations partners on climate change (2011), which led countries to agree and sign the Copenhagen Accord to reduce their greenhouse gas emissions. For the carbon footprint to be reduced, for individuals to actively participate in recycling and reuse, and for protected areas to be established, this may not be enough to restore balance to our Earth. We face the dilemma of our own approaching extinction. . Armed with intelligence and the capabilities of genetic engineering and cloning, we could undo the damage caused by the new age technology that has been proven...... middle of article ...... among extinct species and their revival through cloning can also revive diseases. If a missing animal is resuscitated, it could bring back a deadly disease for which we will not have the understanding or medical technology to prevent a pandemic. Personal Perspective Personally, cloning does not seem to be a long term solution and cloning humans goes against my values, but I do however think that genetic engineering could help prevent extinction, help humans and the environment from what I researched. Conclusion Although there are some risks associated with cloning and genetic engineering of animals to eliminate extinction, the benefits and opportunities remain greater and will help animals, the environment and humans in the long term. I therefore conclude that cloning and genetic engineering are a viable option to help eliminate extinction..
