Environmental science - Research Paper Example Nowadays, 10% of the world is legally protected in one way or the other. In conservation practice, private fundraising is insufficient to pay for the effective management of so much land with protective status hence government assistance should intervene. This paper discusses in depth some environmental issues that negatively affect the Galapagos Island. Galapagos Islands have unknown waters surrounding the famous volcanic archipelagos that consist of natural wonders of a realm that is truly a living natural laboratory. These islands portray a range of mysteries of the deep, caverns buried beneath the earth and primitive wildlife entirely unknown to humanity. These islands remain as hosts for biological mysteries to date. They extensively portray unique geographical features, organisms, and locales. Scholarly research depicts that quite a range of animal species found on these islands seem so unreal to human beings. Charles Darwin, who once visited the islands, formulated a theory embarking on natural selection due to the curious unique species he came across. He used the theory to refer to the evolutionary changes that enables both plants and animals to adapt to the environment. For instance, different environments in the islands have different characteristics that the inhabitants have to get adapted to them. Moreover, Charles Darwin’s perception of natural selection based its argument on the feeding habits of different animal species, climate of the environment and genetic inheritance. Some of the animal species observed from these islands include Blue-footed booby, Waved albatross, Flightless cormorant, Galapagos tortoise, and Galapagos penguin. Although these beautiful sceneries act as tourist attraction sites, they are pessimistically affected by humanity. For instance, several environmental issues such as fishing, poaching of both plants and animals, and introduction of foreign species of plants and animals to the environment

Stem Cell Research Ethical Dilemma Essay Example | Topics and Well Written Essays - 1000 words

Stem Cell Research Ethical Dilemma - Essay Example The functionalities of stem cells allow the body to repair itself internally as they can divide through mitosis so as to replenish other cells. While dividing, stem cells can either remain as it is, that is a stem cell, or can develop into any other body cell such as nerve cell, white blood cell, red blood cell, or muscle cell. It is there unique qualities – as unspecialized cells as well as ones that can be induced to be specialized to perform certain functions – that they have attracted such attention and research from the scientific community. However, the extent to which these cells can be induced under particular conditions is arguable especially due to its association with ethical concerns. While many characteristics can be induced upon the cells by exposing it to different conditions without any harm, the fact that there is a potential danger from such exposition takes over progressive research on the subject. Also, several stem cell experiments on human embryoni c cells for IVF (in vitro fertilization) and somatic cells presents ethical concerns which is seen by many as ‘tinkering’. It is important to consider that science has forwarded and developed as a result of research. Since its early days, the various researches conducted by scientists and theorists have played a central roles in the advancement of scientific knowledge. However, this fact does not ignore the moral and ethical responsibilities of a scientific researcher while she or he is on his path to conduct experiments. Most stem cell research experiments are looked upon as essential discoveries that can lead to a transformation of the modern world. More researcher in the field can provide answers to several of the scientific questions and can also resolve problems associated with human reproduction. The debate revolving around embryonic stem cells is its position on the value of life which may considers an embryo as a person or otherwise. Since embryo is considered to be an early form
