Human Perception of Other Species

The number of wild animals on Earth has halved in the past 40 years . Creatures across the land, rivers, and the seas are destroyed as humans killed them for food in unsuitable numbers, while polluting or destroying their habitats.

The scale and pace of change is dramatic; for example, the extinction of species is occurring at around 100-fold pre-human rates4. The population sizes of vertebrate species have, on average, declined by half over the last 45 years5. More than 2.3 million km2 of primary forest has been felled since 20006. About

Plants and animals on Earth have experienced evolution and extinction since the beginning of time. It is a natural event. In order to adapt, a species needs to be able to survive predators, find food, have a living space, live in the right climate and be able to reproduce. These are all natural processes that influence a species existence. There is another more serious factor that is not a natural occurrence, but is causing a more rapid

Extinction: Most species become extinct because they can’t cope with the environmental change, and also because of introduced species that turned into competitors for

Forests have been cut, crops planted, pastures seeded, and urban areas paved. One of the most troubling consequences of human modification of ecosystems is an ongoing loss of species and therefore a loss of biodiversity around the world. The current extinctions have a human cause: habitat loss (such as clearing of tropical rainforests); the introduction of invasive species; unregulated hunting and fishing; and pollution of water, air, and

Humans do things like: Overhunting, deforestation, pollution and land conservation, destroying the environment for food, materials and research etc. This destroys habitats for certain creatures affecting the whole ecosystem, possibly killing the organisms in the ecosystem.

Summarize: The result of one species extinction could potentially be fatal to the environment. In the animal kingdom, there is a food chain. Keystone animals, are the key ingredient to the food chain. When that keystone animals goes extinct, it sets off a chain reaction on the other animal’s food source. This causes one species to flourish and another to dwindle. The environment needs a healthy checks and balance system to keep each animal population under control (Stuart, 1990 ). Humans can cause the keystone animal to become extinct and therefore, responsible for rise and decline of other species, ultimately, throwing the food chain off balance.

More than 20 football fields of trees are removed each minute. Logging can affect plants and animals by losing their homes. Predator - prey relationships will alter which can then cause a trophic cascade by overpopulation from the prey or extinction of predators. Also keystone species could be removed by these factors. So these living and nonliving factors could affect an ecosystem in many ways. Changes affect the ecosystem strongly in ways which population could boost in biodiversity or severely diminish the population of both plants and animals.

Citizenship What impact are you having on the sixth extinction? After reading the novel The Sixth Extinction: An Unnatural History, written by Elizabeth Kolbert, one wonders if indeed the sixth extinction is the result of actions taken by Homo sapiens. Kolbert describes the scientific theories supporting the five mass extinctions that took place in the past and provides a disturbing theory regarding the sixth extinction period. Kolbert writes, “. . . we are deciding, without quite meaning to, which evolutionary pathways will remain open and which will forever be closed.”

From the smallest fly to the blue whale, from a blade of grass to a towering redwood, everything exploits the natural resources that Earth and its other inhabitants provide. In order to ensure its survival, an organism must assimilate itself into the food web or risk extinction at the hand of natural selection. Sometimes, a species is accidentally or purposefully introduced into a new area. These newcomers, commonly known as invasive species have no choice but to make themselves a part of the food web or die out. Unfortunately, that usually leads to fierce competition for resources between a local species and the invasive one, in which only the victor is allowed to survive. In a relatively short amount of time, the sudden pressure on resources can completely upset and destroy an ecosystem, taking the invasive species with it. With the invasive species destroyed, the ecosystem can slowly rebuild back to the way it was before. According to National Geographic, an invasive species is a “type of plant or animal that is not indigenous to a particular area and causes economic or environmental harm.” (National Geographic).[6] Based on that definition, humans sound suspiciously like an invasive species, except on a global scale. If humanity does not decide to become more sustainable soon, we will suffer the same fate as other invasive species: extinction. Luckily, the pressures of human exploitation of the environment for resources can be mostly eliminated through the use of

Our relationship with nature has currently become strictly economic. we tend to don't associate ourselves as a section of nature as a result of we tend to use it for profit. Forests ar abate for the profits of the lumber trade and to form area for placental mammal. Animals that we tend to ar doubtless associated with, that have senses and therefore the ability to socialize ar slaughtered by the billions to feed Associate in Nursing more and more carnivorous population. Resources like oil and food ar all erratically distributed throughout the globe and thus used as a platform for profit. All the whereas the surroundings bears the grunt of our

The value of environment is changing because animals are disappearing. Like Nora L. Deans said in his book A Nature Balance. “The problem of the endangered environment is not new, and over time larger groups of plants and animals quickly began to disappear” (page 340). This is trying to tell you that animals and plants are dying over time because of humans this is killing them and if animals die then so does humans. Some people do not think that it is a big deal. So that is why we need to help save animals and humans. If there are no animals then we

Throughout The Future of Life by Edward O. Wilson, many major issues involving the natural environment of our planet are brought to the forefront. These issues all have to do with the destruction of our biosphere for economic gain, in the short term, whilst ignoring the long term gains that the environment brings to the economy. This ignorance brings about the extinction of many species that are critical to Earth’s survival. The most concerning of these issues is habitat reduction. Earth’s natural habitats are being destroyed at a catastrophic rate, with many of these species losing their habitat, they no longer fill the niche that they need to in order to survive.

Loss of Biodiversity will affect the life cycle of several species which depend on each other for survival. This dependence determines the survival of species and the change of our environment. Exploiting the biodiverse species to extinction will result in desertification, rise in carbon dioxide in the atmosphere, increased pollution, increased droughts, increase in loss of items that we derive from nature for our own survival such as honey, fruits, vegetables, medicines etc. The greed to exploit will result in our ultimate extinction If a sustainable solution isn’t provided to prevent loss of biodiversity. If we continue the path we are on without taking steps to balance the equation the planet will

The health of the earth degrades with the destructive activity of human beings. A recent study by a group of scientists looked at twenty four different services that the earth’s ecosystems provide for humans, ecosystem services, and found that fifteen of them are in need of desperate help (Gazette 31 March 2005). These services are vital to the survival of both human and nonhuman life and include filtering water and providing nutrient rich soils and ocean waters. Many of the members of these various ecosystems are also decreasing in numbers. In a British survey of bird populations found that in the 200 birds of Britain tracked there was about a 54% population decrease between the 1968-1971 tacking period and the 1988-1991 tacking period. In two other surveys of 254 native plant species from the same area there was a decrease of about 28% during the past 40 years. Humans are pushing the sixth mass extinction (Gazette March 19, 2004).
