Extinction is a natural selection process. Should humans strive to preserve a representative sample of all biomes or aquatic zones? Why should humans be concerned with the extinction rate?…
The animal that was chosen for our team was the Manus Green Tree Snail, and this snail species is endangered. There is only to two main risk to the existence of the species: habitat destruction and over collection. The habitat destruction is the greatest threat to the Manus Green Tree Snail. Over collection is less of a threat than the habitat destruction. Mostly people buy the shell of the snail which protect the snail which causes the endangerment.…
Pimm is afraid that De-Extinction will give politicians and others a way to push conservation into the back seat with the idea that they can worry about it later. (Pimm,…
In conclusion, although involvement to save endangered animals in sometimes necessary, its necessity is hinged on whether it affects the human species directly, and or will negatively affect the longevity of us as a species…
I am on the side of preservation. I think that things should be left as natural as possible. That was the way it was before mankind, and the wildlife was not threatened in any…
4. I think we need to protect most, if not all, of the species, including some unattractive ones like snail darters. As mentioned in the book, we are now mostly focused on protecting “flagship” species, the species that look attractive to us as human beings. When we are amazed at the aesthetic value of those megafaunas like tigers and pandas, we are constantly forgetting the values of small animals like snail darters and many other pants. However, there are several reasons that we should protect those “unattractive species “too. The author of our book taught us that it is almost impossible to restore an extinct specie. When a specie of plants or animals actually disappear, with current technology, we have no way to bring them back. Also, those…
Life on earth is greatly influenced by oceanic habitat. All species are directly and indirectly impacted by the choices made by today’s existing generations. Often times humans outweigh anthropometric value from intrinsic value of habitats they’re not familiar with or exposed to every day. Human decision making functions in a way that focuses on determining costs and benefits of a particular situation, which often leads to the perception of natural resources being seen as available resources solely there to benefit humans. When aesthetic values are neglected, species readily become endangered or extinct and natural ecosystems depleted. Species diversity can be defined as a measure of diversity within an ecological community that considers species richness and evenness of species abundance. Over 80% of life on earth lives in the ocean. Large oceanic beings have experienced a horrific decrease in population over the past century due to majority of the world’s societies living by a ‘Frontier World View’ mentality. Recent human exploitation of Elasmobranchii in particular has had an even greater impact globally than majority of society is aware of.…
More and more people should be educated and aware to the conservation process as it is our duty to save incredible species on our planet. We should understand that every living organism have the same right to live as we all humans we should not disturb the natural bio diversity as it has consequences which can never be healed.

Mass extinctions are very important events to the living organism. When mass extinction happens, it will create huge impact toward the world, negative or positive. For the conservation biologist, they usually think this is a great loss. On the other hand, from the evolutionary perspective, mass extinction could be something good and bad at the same time. Mass extinction would end a lineages and the unique genetic vitiation will be eliminate (Jablonski, 2001). The result of this factor is the loss of the species and it might have some value toward the humankind, such as the medical or economic value. Also, if the extinct species still exist, it might make a different in the world, such as human no longer the most intelligent species in the world.…
First argument why humans have moral obligation to preserve endangered species would be for the reason of biodiversity. Every species are all unique with each other. Each one has its own unique genetic code. So, if one species become extinct, they cannot be replaced. As well as all species have a purpose for one organism or so. Extinction of species would cause the chain of an on going process that occur everyday for organisms to be in disorder. That is, if one would take a species out in the ecosystem, it would lead to extinctions of many other species. As Holmes Rolston (Duties to Endangered Species p. 323) argues, “Extinction shuts down the generative processes. The wrong that humans are doing or allowing to happen through carelessness, is stopping the historical flow in which vitality of life is laid. Every extinction is a kind of superkilling. It kills forms (species), beyond individuals.” Therefore, if extinction of species affects the ecosystem, then it will also affect humanity. Humans benefits from plants and animals, just like plants and animals benefit from humans and to one another. However, short-term effect of extinction may not be visible, but in a long…

The problem is not just the loss of species, but the degradation of the ecosystem after they’re gone, the scientists concluded.…

We should protect these endangered species because if these species go extinct, it can imbalance the ecosystem. Firstly, the ecosystem imbalance can be a threat to the human health. It can prevent diseases and it can also sustain good health for the humans. The ecosystem supplies the humans with shelter, clothing, food and a stable climate. The forests provide the mankind oxygen. If humans keep chopping down all the forests, humans will not have enough oxygen and by the end of the day, humans too will be extinct. Moreover, every single animal is important for the balance of the ecosystem. If one animal has been wiped out, it can ruin the chain life. For example, if algae in the pond is destroyed then the tadpoles that feasts on algae will no longer have food. The tadpoles will die of hunger which…
According to Darwin, it is important for natural variation to take place. This allows a species to change, improve, and adjust to the ever changing climate. Without variation, all species would be like clones, never adapting and soon would die. There have to be certain traits that make another type of the same species better than the other. The species with the bad traits will get killed off and the one with the good traits will get to pass on its genes.…
