Abstract
Biodiversity and ecosystem are crucial issues that have an impact to the human well-being now and in the future. Biodiversity depends on many factors but the most influentive is the habitat loss which influences the biodiversity worldwide. Humans converts native areas into agriculture and industrial areas without realising how much impact it has now and will have in the future. Habitat loss is connected with fragmentation which influence the increasing amount of extinction. The specific climate is essential to be maintained for some species. If it is changed some species may not be able adjust to new conditioins such as extreme weather conditions like drought or flooding and long term changes in water and air temperature. It causing species to die out. It is a huge threat for the ecosystem because every specie is dependet on another one. Another global threat are alien species that become invasive and suppress the native habitants. In addition, species dependent on the suppressed ones will have to adobt or they will become extint.

Out of the 44, 838 species living on the earth, 905 are already extinct and 16, 928 are listed to be endangered and possibly become extinct. Aaet-asean. Retrieved from: http://www.aaet-asean.org/upload/Ear%20Choung%20Chhay-%20Essay.pdf
Considering that many species are not officially assessed on the list, there are probably many more species that does not exist any more. Most of the extinct species died out due to the human activity. The most serious causes of extinction are habitat loss, alien invasive species and the global climate change. In this essay, I will discuss the human factors that are causing the extenction of the species.
Habitat loss and fragmentation are the largest cause of biodiversity

    Important fact to consider is extinction risk is much smaller than total percentage of species influenced by climate change. This is a crucial little explored supporting detail to the author's claim of need to urgently curb climate change. Studies incorporate factors that both increase or decrease predicted risks. Evolution is the major factor for decreasing predicted risks, and it happens pretty slow. The extinction risk is predicted to grow exponentially with each degree of climate change. It's apparent we need to act now to save…

    The Sixth Mass Extinction: True or False?

    It is believed Earth may be in the midst of another mass extinction, also known as 'The Sixth Mass Extinction '.

    Analyze The Impact That The Extinction Of A Species Will Have On An Environment

    When we hear of extinction, most of us think of the dilemma of the rhino, tiger, panda or blue whale; however these are only small pieces of the extinction puzzle. The overall numbers are terrifying. Of the 40,168 species that the 10,000 scientists in the World Conservation Union have assessed, one in four mammals, one in eight birds, one in three amphibians, one in three conifers and other gymnosperms are at risk of extinction. The peril faced by other classes of organisms is less thoroughly analyzed, but fully 40 per cent of the examined species of planet earth are in danger, including perhaps 51 per cent of reptiles, 52 per cent of insects, and 73 per cent of flowering plants.…

    ‘Maintaining biodiversity at its present level is impossible if people are going to achieve a reasonable standard of living in the near future.’

    Biodiversity is especially affected in the Tropical Equatorial Biome where biodiversity is very high. The biodiversity is high due to the climate allowing for a yearlong growing season. The climate has a constantly high temperature of around degrees, varying by only a few degrees throughout the year due to its position close to the equator where there is an overhead sun. There is also a high rainfall of around 2000mm a year due to convectional currents, also a consequence of the overhead sun. The yearlong growing season means there is always a supply of food for animals to maintain their populations. The climate allows for a large biomass of vegetation too, which means lots of species can grow and provide food for a large variety of animal species, further increasing biodiversity.…

    How Does Earth Enter Sixth Extinction?

    According to Buchanan, all species on the earth are entering the sixth great extinction event. A report authored by scientists at Stanford, Princeton and Berkeley universities, found that vertebrates were vanishing at a rate 114 times faster than normal. Gerardo Ceballos, lead author of the research, said "If it is allowed to continue, life would take many millions of years to recover and our species itself would likely disappear early on”(qtd in. Buchanan 3). They also found that there are some species which are…

    What Impacts Do Invasive Species Have On Biodiversity

    Invasive species are the second largest threat to biodiversity after habitat loss, why do invasive species have such an effect on biodiversity? Well invasive species are species of animals that are not native to a certain area or place, normally with the help of humans by boats or aircraft, they start to populate and establish. Invasive species have a greater impact on ecosystems than other species; they have a disproportionate effect, which is what makes them so harmful. Some invasive species are not harmful; some garden plants from other countries are very beneficial, even though they can grow wild they cannot achieve big populations and do not make a big splash on native populations. These are called non-native or introduced…

    Invasive Species

    Since invasive species have no predators, it becomes difficult to keep that parity. What’s occurring in areas invasive species are present is often the population of a particular species diminish while the population of invasive species is on a rise causing the ecosystem to be imbalanced. Obstructive species is an issue society must be aware of and must continue to be involved with until there is a resolution. As a result of this barrier, research is in place to educate the general public regarding invasive species, and funds are currently available. The contribution of managing the rising populace of these species shouldn't be trifled with and the duration of tending to this issue is a step in the right…

    The Five Mass Extinctions

    A multitude of species have vanished in the five cataclysmic mass extinctions, and as of today, about 99.9 percent of all species that have existed on Earth are extinct. These five extinctions were the Ordovician-Silurian extinction, the Late Devonian extinction, the Permian-Triassic extinction, the End Triassic extinction, and the Cretaceous-Tertiary extinction. They wreaked havoc on more species than you could imagine, and if you think today that there are a lot of species, imagine if the five mass extinctions hadn't happened.…
