According to the video in class and the links provided, keystone species are pivotal in the balance of an ecosystem. A keystone is a species whose very presence contributes to a diversity of life and whose extinction would consequently lead to the extinction of other forms of life. Using this information I have come to the conclusion that humans are not a keystone species. Before humans populated planet Earth, life on Earth functioned and carried on for millions of years. It is when human population increased that problems arose on this planet. Now we have issues such as the global warming, an increase in the number of species that are considered extinct , an increase in diseases caused by human ignorance that are killing our own kind and more problems solely caused by people. I believe that if the human population understood better how this planet operates and learn what actions better our environment; we could all live longer and healthier lives without ruining the lives of natural species. Humans have put themselves at the top of the food chain while wiping out those that fall below them. Frank Lloyd Wright once said, Study nature, love nature, stay close to nature. It will never fail you”. The human population is currently serving as a major disservice to nature and I think it is in our best interest to treat this planet with the respect and understanding it deserves; this way we can hang around a little longer.
