NEED AND PURPOSE FOR CONSERVATION OF BIODIVERSITY
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.
The United Nations designated 2011-2020 as the United Nations Decade on Biodiversity. In biodiversity, each species, no matter how big or small has an important role to play in ecosystem. Various plant and animal species depend on each other what each offers and these diverse species ensures natural sustainability for all life forms. A healthy and solid biodiversity can recover itself from variety of disasters. It is estimated that the current species extinction rate is between 1,000 and 10,000
That is, the conservation of selected plants and animals in se¬lected areas outside their natural habitat is known as ex-situ con¬servation. The stresses on living organisms due to competition for food, water, space etc. can be avoided by ex-situ conservation there by providing conditions necessary for a secure life and breeding. Such strategies include establishment of botanical gardens, zoos, conservation strands and gene, pollen seed, seedling, tissue culture and DNA
Native plants in any given area have adapted to all the other organisms in a given area and genetically diverse ecosystems are generally maintained.
The preservation of any species that contributes to the biodiversity of an area. In an ecosystem, the absence of one species creates unfavorable conditions for the others. The. The absence of the spotted owl could have a significant effect on the North Coast forest ecosystems. In order to send the owl population to the right.
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.
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!
According to the IBO, conservation is the sustainable usage of natural resources and preservation is the exclusion of human activity in places not yet infiltrated. One way to ensure the conservation of biodiversity is through habitat conservation. Designing protected areas allows the natural fauna and flora to flourish. However, questions such as these should be asked when creating a protected area: What’s the ideal shape for the reserve? Should the entire reserve be one or should there be separate areas? How close to human society should this reserve be?
The 1992 Convention on Biodiversity (CBD) conceded that the eminent adversity threatening biological and resource diversity is a global calamity. Pertaining to biodiversity alone, studies have revealed that about 1.4 million of all known species (comprising of 26.96% of flora and 73.04% of fauna) are in existence globally (WCMC, 1992; Bhargava, 2006). Despite the rich biological diversities, there are manifestations that, these global diversities are constantly disappearing at quite an alarming proportion. Biodiversity levels are projected to be deteriorating across the globe with about 25% of all mammals threatened by extinction in the next three (3) decades (Yelfaanibe, 2011). Some scholars have advanced reasons responsible for the failure
It wasn 't until recently that I decided that I was going to give up my plan to learn radiology and instead follow my passion for working with animals. Since I was a kid, I have always had a strong interest in animals and their welfare. But it isn 't realistic to own 40 pets so the next best thing is working with them and help make a difference in their lives while I 'm at it. Wildlife rehabilitation is the best label for what I want to do, they take care of orphaned and sick animals in hopes that they can be reintroduced back into their natural environment. A wildlife rehabilitator raises awareness about the challenges facing endangered animals and helps to monitor and boost wildlife populations. I believe that this is the best job for
1. Biodiversity includes variation from the level of genes and genomes to that of ecosystems to biomes. Scientists can measure trends in biodiversity by monitoring the fate of individual species of animals and plants. However, monitoring familiar creatures such as amphibians and mammals do not give a comprehensive picture of life on Earth. The extinction of species can lead to a threat of the sustainability of ecosystems.
The Convention on Biological Diversity (hereafter: “CBD”) is an international treaty adopted by United Nations Conference on Environment and Development, held at Rio de Janeiro in June 1992 and came into force on December 29, 1993. Initially when it came into force there were 168 members now it is 193 in total. The aim to protect biodiversity and the dramatic steps taken for conservation, sustainable use and the fair and equitable sharing of benefits attracted the world communities to become members (History of the Convention, n.d). In principle the convention on biological diversity changed the ownership concept of biodiversity protection i.e. (“common heritage of humankind”) to the “sovereign right” of each member country (Hirsch, 2012). It is the responsibility of the each member to develop and implement policies in a way that helps in the conservation and sustainable use of biological resources. It also recognizes the knowledge of local and indigenous people for conservation and sustainable use of biodiversity (Brahmi et al., 2004).The article 8(j) of CBD has an important provision which gives the member state rights to “respect, preserve and maintain” traditional style and knowledge about the conservation and sustainable use of biological diversity. The protection must promote the wider application of such knowledge and stimulate innovation and also ensure that the benefits are shared in fair and equitable manner to the communities.
Reintroduction is a very costly from this more cost effective ideas can be overshadowed. Within captivity animals lose some vital skills in order for their potential to survive in the wild. Also ecosystems are very dynamic, they are forever changing and adapting. Therefore, by the time species are reintroduced back into the wild. The ecosystem has evolved into something different, due to anthropogenic disturbances or environmental catastrophes.
Many of the issues of biodiversity loss can be traced back to human interaction to the environment. One of the issues is alteration and loss of habitats. A lot of this issue is based on the destruction of habitats and for the land to be used for human consumption. The land is either used up for agricultural use or for neighborhoods. Destroying habitats and building them for our own use can have a positive impact on our way of living but a negative impact on the environment. We would gain land for building land for crops and communities to be built. The habitat for the animals would be destroyed and the species local to the land would either relocate or die. There are restrictions to deforesting land and there are organizations to help protect the land.
These benefits include by giving the chance to public to observe the life specimens of wide diversities in the endangered species. Those who bear the costs include land owners that may lose their traditional land’s value, when the government issues land restriction on private property to protect the species habitat
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
The Earth is far and away the most biodiverse planet in our solar system, with about 8.7 million more unique species than the other 8 planets (UNEP). However, the Earth’s commanding lead is shrinking; not because the other planets are increasing biodiversity, but because Earth’s is decreasing. According to the World Wildlife Fund, we as a planet are losing 1,000 to 10,000 more species than the natural rate. Since the total number of species is hard to pin down, this can mean anywhere from 200 to 10,000 species going extinct per year (World Wildlife Fund). This obscenely high extinction rate is dangerous not just to ecosystems directly affected by the loss, but also creates a domino effect that circles around the globe and up and down the food
Loss of biodiversity is an environmental issue that is causing a lot of global concern. Some of the main causes for loss in biodiversity are alteration of habitats, increasing levels of pollution and human population growth. There are measures that are being taken worldwide to prevent loss of biodiversity. Many wildlife sanctuaries have been built worldwide to preserve the lives of various endangered species. However, it is important to remember that every individual has a role in the protection of wildlife and biodiversity. Every human being should play his part of the role by following simple rules such as stopping others from the hunting of endangered species, preventing deforestation, encouraging reforestation and creating awareness among fellow human beings.
