The world around us exist how excitement. They always exist parallel to each other and parallel to our lives. Our life is extremely rich and diverse, making them hard to understand and explain everything is all that is going on around them. This is the biodiversity. Because of that that we have to take a lot of knowledge from many different disciplines where can understand more clearly, more profound issues of which he has the proper measures, optimized for solving them.Biodiversity is a term expressing the diversity of living individuals, species and populations, the genetic variations between them and all of the complexities of gathering them into the biomes and ecosystems. Biodiversity is expressed at three levels: genetic diversity, diversity of species and the diversity of ecosystems. "Despite numerous attempts in the management of biodiversity in recent years, but the biodiversity of Vietnam remains on the momentum of the recession," said Bui Line, Deputy Minister of natural resources and the environment affirmed that at the event celebrating International Biodiversity Day 2013. Vietnam is known as a center of biodiversity of the world, with a rich natural ecosystems.While genetic diversity is thought to be the difference of genetic characteristics between originated, populations and between the individuals of a species or a population, species diversity is just the level of the number of species richness or species on the Earth side, in a geographic area, within a country or in a particular scene. Species diversity is diverse in terms of number of species, are found in a certain area. In addition, it also demonstrates the difference in one or more populations of a species as well as for the populations of other species. So far, estimates the world has about 1.7 million species have been identified. But essentially there to 12.5 million species on Earth. According to the report of the United Nations development program in Vietnam (UNDP), nearly 900 species are endangered and there are at least 10 species have become extinct in Vietnam, including the Javan Rhino.First, we talk to the plant world. The plant is very diverse in species, body structure and activities were adapted to different habitats. According to ke has about 300 thousand species of plants in the world. In Vietnam there were about 15 thousand species, of which there are about 2300 species of economic significance. Forests in Vietnam covered almost 50% of the area with incredibly diverse flora, rich. The animal is also equally diverse. The number of animals lived on the Earth are rising fast, especially mammals, when approximately 1/5 of the animals are endangered in front. jungle animals have made significant contributions to the economic development of the country and is an important basis for the protection of the ecological environment and sustainable development. But, due to many different causes, this resource has been seriously degraded, is in danger of extinction or depletion of a number of worrying. About diverse ecosystems, there is a definition and classification for the global level. Diverse ecosystems are typically evaluated through the diversity of the members; It may include the assessment of the relative abundance of the various species, as well as the diversity of species.Due to various causes, biological diversity is the most valuable resource, a huge role with respect to nature and human life are seriously degraded. But we are conscious of our interests but we are gradually destroying the diversity thing. There are two main reasons causing the degradation of biodiversity, it is due to the adverse impacts of natural and human, in which the human influence caused particularly severe from the mid NINETEENTH century to the present and mostly do change and degradation extensive landscaping and that has pushed the species and biome in survivor. The wrecker, separating degenerate born landscape, exploitation of species for your needs, introduced foreign species and increasing disease also causes significant degrade the biological diversity.The main factors causing the problem is the lack of sexual abuse and exploitation of human consciousness. The indiscriminate deforestation, Habitat metastasis migration of some nationalities, ... do damaged vegetation, caused many consequences such as loss of housing, land being the Wolf Trail and degeneration, droughts, flash floods rise, etc. The hunting of rare animals, a religious cause ecological imbalances. The mills, factories when production activities also emit poisonous gases, causing an endless black sky turn dark. The gas then when flying into the air part will cause respiratory diseases in humans, part evaporates up, met the cold will condensed into clouds, creating acid rain make the buildings were damaged. The peasant since the libido of profits that have used bluff the insecticide, herbicide caused water supplies around the heavily polluted, the creatures living underwater die-off, also pollute the atmosphere, affecting human health. The main reason do jungle animals resource degradation fall victim to unauthorized dealers, hunting and forest loss; The decline of forest conversion due to the purpose of use, industrial development, tourism and service has resulted in loss of Habitat, distribution and Habitat disturbance of species. Due to the market demand for the products originating in wildlife is increasing, leading to excessive hunting accident and the management have not yet effectively did for wildlife populations suffered serious decline.The value of biodiversity is extremely large and can be divided into two types of values: the value of direct and indirect value. Direct economic value of biological diversity is the value of the products that are direct human exploitation and use for your needs; indirect value also includes the ones that humans could not sell, the benefits which include the quantity and quality of water, soil protection, regeneration, education, scientific research, climate and provide the means for the future of human society.Firepower, we must protect the diversity it for all the living things in the ecosystem has a close relationship with each other and have a relationship with us. The forest has a great role in the climate, moisture retention for the soil, avoid hither and land desertification. Forests retain water and regulate the amount of water on Earth as steady flows, restrict flooding, painting the Wolf Trail. The forest is where the breed, is Habitat for the animal. The forest also provides gas and manual materials and countless types of precious medicinal herbs. It provides a food source for animals.Along with other resources, the forest animals have made significant contributions to the economic development of the country and is an important basis for the protection of the ecological environment and sustainable development. Each animal species is a key chain with each chain and litter for food. Animals contribute to the process of material metabolism and circulation in nature, created the ecological balance. Animals contribute to the spread of plant and thereby participate in maintaining the diversity of living organisms. Animals also provides a source of food and nutrition for human beings, the source of medicinal herbs, raw materials for manufacturing industries and human activities. Animals provide traction, industrial and agricultural products. Some species have cultural value, some species of which destroy harmful organisms. We have to conserve the animals you hiêm because now the hunted rare animals indiscriminately, unplanned exploitation of human beings, environmental pollution has led to a number of extinct species of rare animals. due to many different causes, this resource has been seriously degraded.Before that situation, we need to take the best measures to address these problems. The conservation of biodiversity is not only the responsibility of scientists, conservationists and nature that is the responsibility of each person living on this blue planet.We need to take measures to exploit and use biological resources in a reasonable way and efficiency, combined with the protection and rearing, avoid waste of resources. Do not use the guest approach, getting started was prohibited so as not to affect the living environment and the reproduction of living things. Need to build nature reserves, ecological zones to increase natural habitat area for species breeding at the same time, in order to preserve the rare species. The establishment of the system of protected areas is very important step in the conservation of the species, biome and ecosystem. The reserve is defined as
