Throughout much of human history, human civilizations found food by the killing of animals whether it be mammals, reptiles, or amphibians. Humans have allowed the extinction of many animals by simply hunting them for food or hunting them for trade and commerce. Although humans play a vital role in the animal extinction process, they are not the sole contributor. Climate change affects the weather in terms of temperature or precipitation which in turn causes animal food sources to perish allowing animals to suffer from starvation. In my script, I describe a future that consists of humanity without animals and the only food source being insects. With the repetition of animal killings and occurrence of climate change, we can only expect to cause …show more content…
The rise or fall of temperatures and the lack of precipitation can resort in consequences such as vegetation dying which can mean a lack of food supply for the animals and ultimately mean the death of animals. Extinction has been a theme in many readings throughout the course including Helen Simpson’s Diary of an Interesting Year. In Simpson’s short story she states, “No creatures left except squirrels, rats, and pigeons, unless you count the insects” (109). In this short story, the audience views that in the year 2040 nearly all animal species have gone extinct due to “the Big Melt” which is based on climate change (101-115). In the horrible conditions described within the story, insects prove to be survivors that are capable of outlasting any other species. In my script, humans get their food from the “insecto-snapper” which is just an insect trap because insects are the only means of food and protein in this futuristic situation. Simpson’s short story connects with my script by discussing the result of extinction and how much of an affect the loss of animals have on humans and their ability to survive without animal meat. One other reading that has the extinction theme was Lydia Millet’s Zoogoing, which describes animals who are “alone on the earth, vanishing” (39). Millet’s short story tells of a world that is in the process of extinction but still has the effects of a world without animals. Both Simpson and Millet’s short stories contribute to my script by describing a future where humans no longer rely or care about animal
An English naturalist Charles Darwin (1802-1882) developed a theory of biological evolution. He studied variation in plants and animals during his five years’ voyage around the world in the 19th century. Darwin studied hundreds of species, which he researches variations between locations. His theory states that all species of organism arise and develop through natural selection. Natural selection is the process of organisms that adapt to their surrounding environment, which tend to survive and produce more offspring. Killer whales are remarked to have evolutionary links from land dwelling organisms, millions of years ago. This paper will display the evolution and natural selection of the killer whale.
Long-term survival of a species depends on its ability to adapt to changing environmental conditions (Murphy, 1994). Genetic diversity within a species, which has taken 3.5 billion years to evolve, makes adaptations to these changing environments possible. Unfortunately, the rate of extinction of genetically diverse organisms is rapidly increasing, thus reducing this needed biodiversity, largely due to the human impacts of development and expansion. What was an average of one extinction per year before is now one extinction per hour and extinct species numbers are expected to reach approximately one million by the year 2000 (WWW site, Bio 65). As a result governmental and societal action must be taken immediately!
Extinction is no longer just a natural process. It is an enemy, slowly changing our world into a barren wasteland where life is as rare as a flower in the Arctic Circle's winter. The wolf, the tiger, the caribou, the elephant, the bison, the cheetah, the sequoia cactus, the redwood tree – all of these and so many more things are on the verge of disappearing from our planet forever. Extinction is the most pressing environmental issue of our time, because if it continues the way it is going without anything being done to counteract its causes and consequences, there will soon be no environment left for there to be debates about.
Over a century ago, humans fought animals for dominance of the landscape and we regrettably won, now they’re in need of our protection. The Government and Organizations have come to the rescue of wildlife species all across the U.S. Their main goal is to protect wildlife species from over harvesting and also their loss of habitat due to industrial and residential development. The beauty and curiosity of wildlife captivates all of us for different reasons. For certain species, they are the link to our existence Animals are not being hunted into extinction because the government is protecting certain wildlife areas and are controlling the animal populations within those certain areas. While increasing a wildlife species population and removing from the endangered species list, a predator such as the gray wolf, is sure to be seen as a success to some and a threat to others.
Modern-day genetic technology has granted mankind with the opportunity to bring back extinct species from the dead. If humans have come to possess the DNA from an extinct animal population, it is possible to create an identical clone of the animal in question, effectively “bringing it back from the dead”. Many ethical dilemmas surround the practice of de-extinction, and rightfully so. Recreating an extinct species could produce groundbreaking scientific breakthroughs, generating exciting opportunities for future genetics-based research. However, there could also be monumental consequences: the newly revived, once-extinct species might destroy the ecological equilibrium of modern Earth
Global warming has become a more prominent issue every decade since the mid 1900s. The increased temperatures are leading to substantial ice loss. This loss in ice is causing severe destruction to polar bear habitats and homes and is leading to their extinction. It also is affecting their food supply. Global warming is making it harder for polar bears to repopulate and is causing a decrease in the overall size of each bear. The chemicals associated with global warming are getting into the food chain and eventually into the polar bears themselves. Global warming is causing the extinction of polar bears in the arctic because it’s destroying their homes, decreasing their food supply, is affecting chemicals in the air and in their food, decreasing the average size of the bears, and contributes to a decrease in reproduction.
Imagine a world where there are no animals anywhere. There are still the ordinary cows, pigs, cats, dogs, but there is not a single tiger or rhinoceros. People all around the world have been killing animals for thousands of years and they need to stop and obey the laws. Make your voice heard for the animals; they can’t speak for themselves so we need to do it for them. Other reasons on why animals are getting put on the endangered species list and or going extinct: habitat intrusion, pet trade, climate change, and disease. Please help to save the animals or they won’t be here any longer.
Humans are very quickly dominating the globe. Today, the human population is around 7 billion people. Humans are populating at a rate of almost 220,000 per day! Humans are rapidly heading towards Earth’s carrying capacity.

Did you know that more than 90 percent of all organisms that have ever lived on Earth are extinct? According to Pandey, the author of Humans Pushing Marine Life toward ‘Major Extinction’, nearly 10,000 species go extinct each year, and this rate is estimated to be 1,000 times higher than the natural extinction rate (1). Human beings are causing irreversible damage to the oceans and their wildlife, which is being led by two major reasons: Commercial fishing or over-fishing, which damaged the marine environment and caused a loss in the marine life diversity, and pollution, which is a primary way of the extinction causes that drastically modifies the marine life habitat. As a result of the commercial fishing and pollution, many of the marine species will start disappearing of the oceans. Briggs emphasizes that over-fishing “has induced population collapses in many species. So instead of having less than a hundred species at risk, as was the case some 30-40 years ago, there are now a thousand or more (10).”
Chapter One: Animal Negligence Animal Abandonment Animal abandonment. The word makes me sick. The whole IDEA of animal abandonment sickens me. Basically, you decide, Oh, I don’t want this dumb pet anymore.
Climate change is one of the major issues surfacing earth over the past century. The earth’s temperature has increased over the years leading to detrimental effects on the economic and life sources of people, especially that of agricultural production and livestock. The Merriam-Webster online dictionary (2014), defined climate change as a change in global climate patterns apparent from the mid late 20th century. The Intergovernmental Panel on Climate Change, IPCC, (2007) predicts that by 2100 the increase in global average surface temperature may be between 1.8° C and 4.0° C. With increases of 1.5° C to 2.5° C, approximately 20 to 30 percent of plant and animal species are expected to be at risk of extinction. Moreover, the IPCC (2007) purported that climate change has severe consequences for food security in developing countries. There are numerous factors that are solely responsible for this change which are both natural and man-made. Climate change has led to a decrease in quality and quantity of plant produce and livestock because of heat stress, drought and an increase in plant and animal diseases.
Animal Cruelty has many forms, many reasons and most importantly many victims. It is a growing problem in today’s society. Many people may wonder why people abuse animals. The thought is simple, however the answer is a little more complex, there are three main types of animal cruelty. The three reasons are as follows: unintentional, intentional, and cruel intentions. I will discuss each one in more detail.
Stray animals are dangerous reason being is children or elderly people can be bit while walking or playing around at parks. I live in Mercedes and at one point when I was walking from stars to the high school, and stray dog for no reason started growing at me and my instinct was to run until I got the a building. This can happen to anyone, they can be attacked trying to touch a stray or just simply walking by, or even worse a child can catch a disease. Also owners with their pets are also getting attacked by stray animals because they strays tend to be over protective of their territory, or they just want to fight with the pet of the owner.
In our world today we have approximately 26,021 endangered species. Endangered species are organisms that may possible become extinct. The term 'endangered species' refers to all species that fits this description. However some conservation biologists and scientists normally use the term ‘endangered species’ to refer to species that are put on the IUCN(International Union for Conservation of Nature)Red List. Many factors can be looked at when considering the conservation status of a species. Factors such as human threats or environmental threats can cause a species to become endangered.
