A fuller definition is given in the Convention on Biological Diversity (CBD) from the Earth summit: ‘Biodiversity is the variability among living organisms from all sources, including terrestrial, marine, and other aquatic ecosystems and the ecological complexes of which they are part ; this includes diversity within species, between species and of ecosystems’ (Hambler, C., Essay on Biodiversity – Essay 1 ( Words) Introduction: Biodiversity also known as biological diversity is the variables that exist among several species living in the ecosystem. These living organisms include marine, terrestrial and aquatic life.

Human Impact on Biodiversity
Human Impact on Biodiversity. Trisha Hostetter, biodiversity essays. Biology Senior Seminar. November 21, Thesis: Humans affect biodiversity on many levels and it is important to realize these effects biodiversity essays an individual, societal, biodiversity essays, and government level and attempt to minimize them in order to ensure biodiversity essays future for humanity.
Biodiversity Defined and Why It Is Important. Extinction of Species. Rates of Extinction. Cause of Extinction. Human Actions. How to Determine Impact. Human Population. Climate Change Problems. Poverty and Biodiversity. Logging in Malawi.
Rich vs. Government Actions. President Bush. Kyoto Protocol. Regional Greenhouse Gas Biodiversity essays. Debt for Nature Swap. Many individuals do not think about the damage they are causing on biodiversity. However, it is important as humans to realize the impact we have on biodiversity because without it, biodiversity essays, there would be no human existence.
If no changes are made in the ways humans use resources on earth, there will continue to be a degradation of biodiversity until human lives can no longer be sustained. Humans affect biodiversity by their population numbers, use of land, and their lifestyles, causing damage to biodiversity essays for species.
It is important for humans to realize how their actions affect biodiversity and the importance of maintaining what biodiversity is left on the earth. Through proper education, biodiversity essays, and by demanding that governments make decisions to preserve biodiversity, the human population will be able to sustain life on earth longer.
Biodiversity is the term that is given to describe the variety of life on earth and the natural patterns it forms, biodiversity essays. It is the result of evolution, natural processes, biodiversity essays human influence. SecretariatBiodiversity involves diversity of genes within a species, of species within ecosystems, and of ecosystems in the biosphere Frequently Biodiversity is not determined by only one factor, but rather many factors that differ spatially and temporally Climate Although many humans may not biodiversity essays how important biodiversity is to them, it is clear that without it humans would not be able to exist.
Each day biodiversity essays use 40, species, most of which go totally unnoticed Eldredge Simply put, there would be no population of humans without biodiversity. The most obvious indicator of biodiversity is the number of species on the planet. Currently there are 1. To look at the loss of biodiversity, the number of extinctions of species should be examined. This rate is 50 times the natural rate of extinction and is expected to increase in the coming years Sherbinin The extinction rate is of great concern because once a species is extinct, biodiversity essays, there is no chance of ever getting that species back on the planet.
Three main problems that cause species extinction are: habitat loss, degradation, and fragmentation Noss et al Habitat loss is described as the complete destruction of a habitat. An example of habitat loss would be logging of a forest.
Habitat degradation is when a habitat diminishes to a point where it can no longer support biological communities Effects An example of this would be habitats that are polluted by industry.
Habitat fragmentation is described as a habitat that is broken into smaller discontinuous segments of land for development Mapping An example of this would be putting a road in the middle of a habitat, biodiversity essays. All three of these problems that result in species extinction are directly related to human influence.
There is no clear way of determining the total impact that humans are making on biodiversity; however, it is obvious that many actions by humans are causing a decrease in biodiversity. To determine the total impact that humans are making on a given environment, the area of productive land and water needed to produce the item that is being consumed and the need to account for the waste being generated biodiversity essays humanity must all be taken into account according to management and production practices in use during that time Wackernagel et al, biodiversity essays.
Direct or indirect actions by humans have resulted in the decrease of biodiversity, biodiversity essays. The Convention of Biological Diversity states that there are both indirect and direct human drivers. Some of the indirect human drivers are demographic, economic, sociopolitical, scientific and technological, and cultural and religious factors.
Some of the direct human drivers are changes in local land use and land cover, species introductions or removals, external inputs, biodiversity essays, harvesting, biodiversity essays and water pollution, biodiversity essays, and climate change Climate In the next 50 years it is expected that humans will seriously impact percent of land in developing countries.
This is a result of growth in population and in over consumption of natural resources Mappingbiodiversity essays, The population of humans is, biodiversity essays, what many consider, the root of the biodiversity biodiversity essays Eldredge The number of humans on earth, as of Julyis at 6.
The increase in human inhabitants causes a problem because with it comes a need to convert natural habitats to land for human consumption. One way that the humans have been able to sustain their growth is by converting natural habitats to fields where foods can be produced.
In the United States there is a direct relationship between the loss of forests to the increase in cropland Dobson Internationally, there is half a hectare of tropical forest disappearing to farmland every second, biodiversity essays.
One of the potential dangers of decreasing the amount of natural habitats remaining is that species will no longer be present on earth.
This directly affects agriculture because many of the species that are being destroyed for croplands may have been used for genetically enhancing crop products Frequentlybiodiversity essays, In this manner, biodiversity essays, the increase in agricultural land biodiversity essays harms our agricultural future. Human actions have also played a role in climate change, biodiversity essays, which is also causing great danger for biodiversity, biodiversity essays.
The change in climate is due to increased atmospheric concentrations of carbon dioxide, which causes increased land and ocean temperatures, and changes in precipitation and sea level rise, biodiversity essays. With the change in climate also comes a change in species. Climate affects the timing of reproduction and migration, the biodiversity essays of growing seasons, biodiversity essays, species distributions and population size, biodiversity essays, and the frequency of pest and disease outbreaks.
It is also expected that the change in climate in the 21 st century biodiversity essays have a much higher rate than the past 10, years biodiversity essays create an even bigger impact on biodiversity Climate It is expected that 80 percent of biologically rich regions will suffer great losses of plant and animal species because of global warming. The rate of change of habitats is expected to increase up to ten times due to global warming Sherbinin Biodiversity affects everyone to varying degrees, biodiversity essays.
People that live in poverty depend heavily upon nature to provide them with resources to live. In third world countries logging has become a common activity of the poor. It is a huge problem in many developing countries because it is destroying natural habitats, yet it seems to be one of the only ways that people can make enough money to support their families. The New York Times recently ran an article about individuals in Malawi illegally cutting down trees in order to make enough money for food, biodiversity essays.
One individual states, "We have no money to raise our families. We have nowhere to run, biodiversity essays, nothing else to do.
So we have to cut the trees to feed our families. The current rate of deforestation in Malawi is 2. Wines The degradation of the environment will affect both poor and industrialized nations.
However, The developing nations will be the ones that are affected the most by the degradation of the environment by increasing poverty, reducing labor productivity, and exacerbating the current economic social crisis Mapping Developing biodiversity essays do not have the resources to help their citizens find an alternative to use nature for survival, biodiversity essays.
Educating individuals in developing countries about the need to preserve biodiversity is a must for ensuring human survival. Educating locals on the impact people are making on the environment and showing people how they can live in equilibrium with nature, will help preserve biodiversity without causing further oppression.
Many times individuals do not realize that there are alternative ways of obtaining money that do not put the environment into jeopardy. Biodiversity essays example, in the case in Malawiif the locals were to obtain honey from beehives found in the forests they would be able to make more money than they would by selling wood Wines General education in developing countries is very important to biodiversity even if it does not focus directly on sustainable living.
There have been significant studies that have shown that educating and empowering women lead to a decrease in birthrates which would make a huge impact on population growth, especially since developing nations have a higher birthrate compared to industrialized nations. Simply educating individuals, biodiversity essays, all individuals, not just impoverished ones, about their impacts on biodiversity is a step in the right direction.
Eldredge Governmental Actions. Although there are actions individuals can make that can assist in helping the biodiversity problem, biodiversity essays, it is important for governments biodiversity essays take actions that will provide a larger scale effect on saving biodiversity.
The George W. Bush administration biodiversity essays not known for protecting the environment. President Bush has eliminated the roadless rule, which was a rule that kept logging and roads from being present in 60 million acres of national forests. Bush has also cut 42 million acres of critical habitat from the 83 million acres that are needed for threatened and endangered species. There has been a biodiversity essays decrease in the amount of designated wilderness in the United States.
