Do we all know what biodiversity means? Well I think some of us do not know what biodiversity is, but it is important for us to know is the meaning of biodiversity. Biodiversity is the variety of life. Most of the people recognize biodiversity by species but biodiversity is more than just species. A species is a group of living organism that can interbreed for example white-tailed deer, blue whales, and bacteria that you cannot even see with your eyes. Species is only one part of biodiversity. Biodiversity can be studied on many levels and at the highest level you can look at all the different species in earth. Biodiversity occurs at multiple scales of ecological organization, from genes all the way up to the entire biosphere. The full range of species that lives in a particular area is included to biodiversity. Here in the Philippines, we are rich when it comes to biodiversity. As a paradise of biodiversity, our country the Philippines’s terrestrial ecosystems
They also destroyed the natural habitats of the many species in this country. I am doing this research for us to know that we are not the only one that is living in this country. That there are so many species that is also lives here in the Philippines. There are the animals like dog that serves to be our best friend cat, bird, fish and etc. There are also plants that help us human to inhales or breathes fresh air and stayed alive, sometimes its serves for our food and also for animals for them to stay alive. If we do not stop all those wrong doings that we are doing right now all of those species will be homeless. If we continue all of that wrong doings one day we just notice that are country, our world is not that clean, fresh and beautiful just like the past
(http://www.encyclopedia.com/doc/1O7-densityfrequencydominance.html) Biodiversity is the number of richness or the number of species in a local area. This happens when someone can look at a species, in order to indicate a degree of uncertainty. This can happen by calculating the number of species given, where the individual is picked at random from the community. In other words, if the diversity is high, then oneself will have a poorer chance of correctly calculating the species of the next individual picked at random. (http://www.tiem.utk.edu/~gross/bioed/bealsmodules/shannonDI.html) This experiment was a way to find out the diversity of the school parking lot and the possibility to identify the type or model of the student’s, faculties and guest
In the article "Island Civilization: A vision for human occupancy of earth in the fourth millennium" a very good point was made about how humans are not treating the earth with respect, however our generation still has a chance to turn the earth from cancerous to healthy.
Landscape fragmentation contributes to loss of migratory corridors, loss of connectivity and natural communities, which all lead to a loss of biodiversity for a region. Conservation of biodiversity must include all levels of diversity: genetic, species, community, and landscape (CNHP 1995). Each complex level is dependent upon and linked to the other levels. In addition, humans are linked to all levels of this hierarchy. A healthy natural and human environment go hand in hand (CNHP 1995). An important step in conservation planning, in order to guarantee both a healthy natural environment as well as a healthy human environment, is recognizing the most endangered elements.
Biodiversity is the variation and amount of species across the globe, or within in a specific geographical habitat. There are three different areas of study within biodiversity; ecological diversity, species diversity and, genetic diversity. Science Book Species diversity is the variety of different organisms and relationships within a specific species, this essay will discuss the declining of species diversity among sea turtles and the implications it has on the worldwide seas. I have chosen to research about the topic because, sea turtles are believed to have been alive during the Jurassic period. However, now all seven sea turtle species are critically endangered or vulnerable, due to human activities such as; commercial fishing, bycatch and, climate change. (WWF, OCEANA, ACTIONBIOSCI)
The ecosystem I have chosen is tropical rainforest. In the following paragraphs, I am going to firstly introduced the structure of tropical rainforest in brief, with the second part of the plant ecology and last the diversity within this ecosystem.
The reason I found this so fascinating was that it made me remember the fact that all species will inevitably be extinct, just with the connection that even all great nations will soon crumble such as Egypt, one of the greatest nations that had ever lived, but have had its empire destroyed from the Roman empire, whose empire has also soon been crumbled from other countries. With the extinction of human beings, there could be a possibility of other species still able to survive, or no other species that are left to survive on the planet. Human beings have a massive impact on other species whether it is beneficial or consequential to them. Such as providing with habitats so that they won't go extinct, or hunting them down with weapons that cause harm. The most likely case that will cause the extinction of humans could be the sixth mass extinction that is predicted to occur in a few million years. The 6th mass extinction could wipe out most of the human population and cause the few remaining humans who have survived the crisis, to also be extinct due to the limited resources that have been destroyed. There could be a possibility of newer species that rise up that become more advanced and more complex species, these new species will most likely be
There are many aspects to include when defining diversity. Diversity is understanding biological variations, space, social organization, communication, time and environmental control of a culture. The first aspect is understanding the different biological variations within different cultures of people. Biological variations include: body structure,
In The Diversity of Life, Edward O. Wilson reflects on how the living world became diverse and how humans are destroying that diversity. In the book’s preface, Wilson defines biodiversity as “the totality of inherited variation in all organisms in a selected area” (Wilson ix). He adds that modern technology will allow for us to find many new species that were previously unknown to be in existence.
Humans are the cause of environmental damaging things like acid rain and global warming. People also damage other species by killing them till extinction or causing things like oil spills that cause them to die. Why destroy the only place the human species lives on, instead people can spend their time restoring the planet and making it better, they can learn to coexist with other species instead of learning how to be the dominant and overpowering species.
Humans are destructive. Not a lot of us think about how what we do affects the world around us. We almost act like we are the only ones on this planet. We go around polluting and destroying our world with no regard for our actions. The things that live out in the wild are paying the price for it. Every day that passes there is another animal or plant that is placed on an endangered list. This is happening at an alarming rate. Because of man’s desire to expand and conquer their surroundings, there are animals and plants that are on the brink of extinction that will not be around for our kids and future generations to enjoy if something is not done about it now. This problem has been going on for hundreds of years. There are animals and plants that can only been seen in paintings or early photography. It is because of our early ancestors that we have this problem today and we have to do more to prevent more animals and plants from disappearing forever.
Biodiversity conservation is about saving life on Earth in all its forms and keeping natural ecosystems functioning and healthy. Biodiversity is being depleted by the loss of habitat, fragmentation of habitat, over exploitation of resources, human sponsored ecosystems, climatic changes, pollution invasive exotic species, diseases, shifting cultivation, poaching of wild life etc. Since the human beings are enjoying all the benefits from biodiversity, they should take proper care for the preservation of biodiversity in all its form and should prevent the degradation as well as the destruction of the habitats thereby maintaining the biodiversity at its optimum level which will ultimately conserve the biodiversity for the future generation.
We have contributed to the harming of species and habits with factors such as deforestation, over fishing, poaching and pollution by factories. Our carbon footprint has caused a whole in our ozone layer and caused a green house effect commonly known as Global Warming. All these issues upon our environment are threatening the Earth’s biodiversity and increasing the amount of endangered and already extinct species.
Nowadays it is common to read articles in newspapers and magazines regarding biodiversity issues. Human beings have been knowingly and unknowingly destroying biodiversity since their existence. Biodiversity is the measure of the variety of species of animals living in an area. Forests are usually areas with high biodiversity while deserts are the opposite. Human beings have always destroyed biodiversity either by deforestation, or by some other means. Biodiversity depletion is a natural phenomenon. But the present levels of biodiversity depletion are many times higher than the natural rate. Recently the levels of loss in biodiversity have started causing global concern. Some of the main causes for loss in biodiversity are alteration of habitats, increasing levels of pollution and human population growth.
Everyone’s all seen those wildlife shows on tv. The shows on National Geographic and such, showing animals in beautiful environments, everything lush and growing and nothing at all wrong that could threaten these creatures and places. But, have anyone seen the other side? The side where all these beautiful creatures and plants starve, are decimated by predators that have never been there before, and sometime even become poisoned by their very own homes and habitats? Of course no one has. That doesn’t mean that its not happening. It is happening, and its happening everywhere. And guess who is to blame? People. Society. Humans as a race pollute the environment, hunt animals simply for their parts, fish way more than humans will ever need just for the sake of money, introduce new species to new places for our own gain, and even purposefully destroy entire regions just for human expansion. And its starting to take its toll. While it is true that nature is constantly in flux and certain species come and go, humans are causing more species to disappear in the past few hundred years then nature has ever caused since the age of the dinosaurs, and therefore it is up to humans to repair the damage caused, be it cleaning the environment and habitats of these creatures, or taking more direct action to protect and preserve the species that are on the brink of extinction.
NEED AND PURPOSE FOR CONSERVATION OF BIODIVERSITY: Biodiversity, a contraction of “biological diversity,” generally refers to the variety and variability of life on Earth. The very existence of human species and sustainable development depend on biodiversity conservation, therefore the need for conservation of biodiversity is basically for this reason that all living creatures need other creatures and plants in one way or the other. At least 40 per cent of the world’s economy and 80 per cent of the needs of the poor are mainly derived from biological resources. Biodiversity is necessary for our existence as well as valuable in its own right as it provides the fundamental building blocks for the many goods and services which are essential
