Biodiversity, short for biological diversity, is the term used to describe the variety of life found on Earth and all of the natural processes. . The different aspects of biodiversity all have a very strong influence on each other. It is helpful to think of an ecosystem as a woven carpet. Climate change is a major threat to biodiversity. Energy which is a major part of Biodiversity usually defined as the ability to do work. An energy system may be thought of as an interrelated network of Biodiversity and stores of energy, connected by transmission and distribution of that energy to where it is needed. The transformation from stores of energy in food to work and subsequent dissipation of energy is an example of such a system. It is now widely recognized that biodiversity and climate change are interconnected. Biodiversity is affected by climate change, with negative consequences for human well-being, but biodiversity, through the ecosystem services it supports, also makes an important contribution to both climate change mitigation and adaptation. Conserving natural terrestrial, freshwater and marine ecosystems and restoring degraded ecosystems (including their genetic and species diversity) is essential for the overall goals of both the Convention on Biological Diversity and the United Nations Framework Convention on Climate Change because ecosystems play a key role in the global carbon cycle and in adapting to climate change, while also providing a wide range of ecosystem services that are essential for human well-being and the achievement of  the Millennium Development Goals.

Plants define the habitat of a site, providing structure, shelter and food as well as contributing to the overall biodiversity. Plants are a kingdom of life forms that includes familiar organisms such as trees, herbs, bushes, grasses, vines, ferns and mosses. Through photosynthesis, they convert water and carbon dioxide into the oxygen we breathe and the sugars that provide the primary fuel for life. Plants were instrumental to evolution as a whole in that they produced the oxygen that made life on Earth possible — not only by "breathing" it into the atmosphere and transforming it, but also by crushing rocks with their roots, which created soils and released nutrients on a large scale. Plant diversity is well represented in rural areas, development pressures have reduced the amount of green space in urban and peri-urban areas, resulting in a poorer diversity of plant communities. However, there are still many small pockets of green space within the built environment with a rich diversity of plant species, and other areas where improvements to green space could encourage the establishment of plants. Management of urban green space directly influences the micro-environment and can create conditions favorable to a range of plants, which in turn can increase habitats for, and therefore the diversity of, other species groups. How animals have adapted to survive and thrive in their environmental riches? is one of the most fascinating aspects of biology. Farm animal biodiversity is important for maintaining genetically diverse and healthy livestock. However, this diversity is being threatened by industrial farming operations that depend on a small number of farm animal breeds that can thrive in an intensive livestock environment. Because of this, farm animal breeds that don't thrive in factory farming operations are becoming more rare. Variability is essential for the evolution and adaptation of living organisms, including animals be they wild or domestic, and constitutes a vast field of research. Such research will lead a better understanding of the ecosystemsand the discovery of various molecules with potential benefits to the humanity. biodiversity Protection is therefore crucial both for animals and humans, in particular at a time when global challenges are posed by growing human population; increasing movement of goods, animals and people, together with pathogens and invasive species; and climate changes, to name a few.

Biodiversity is now commonly defined as the variety of life in genes, species and habitats. According to the definition of the Convention on Biological Diversity, biodiversity is the variability among living organisms from all sources, including inter alia, 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. The three domains of life, bacteria, archaea and eukarya are present in the marine environment. In addition there are viruses. About 230,000 species of marine plants and animals have been scientifically described and a few thousand bacteria and archaea. This known biodiversity only represents a small fraction of the number of species existing, except for the macrophytes and seagrasses which are living in coastal environments and, in general, for the pelagic environment. Species diversity in the oceanic pelagic environment is extremely low. Habitat diversity and the number of marine habitats are difficult to define. Studies of zonation have typically demonstrated the existence of very narrow zones in intertidal areas, where direct observation is possible, and broader and broader zones as one goes deeper. Marine ecosystems deliver a series of services that are essential to the proper functioning of the Earth. These include the production and mineralization of organic material, the storage of carbon, the storage of pollutants and waste products from land, the buffering of the climate and of climate change, coastal protection (mangroves, dune-beach systems, coral reefs). Most of these services are delivered by microscopic organisms. Marine Biodiversity research an important product of marine biodiversity research should be the necessary knowledge and tools for adequately managing and protecting marine biodiversity. This requires knowledge on genetic and ecological mechanisms that control biodiversity (gene flow, dispersal, adaptive value of genetic polymorphisms, determination of dispersal and recruitment, species interactions including invasions, sediment transport, natural and human-induced catastrophes, etc.). It also requires knowledge on the functional role of biodiversity.

Conservation of Endangered Species is done by Captive breeding Captive breeding is the process of breeding rare or endangered species in human controlled environments with restricted settings, such as wildlife preserves, zoos and other conservation facilities. Captive breeding is meant to save species from extinction and so stabilize the population of the species that it will not disappear.  Additionally, if the captive breeding population is too small, then inbreeding may occur due to a reduced gene pool and reduce immunity. In 1981, the Association of Zoos and Aquariums (AZA) created a Species Survival Plan (SSP) in order to help preserve specific endangered and threatened species through captive breeding and Private farming. Where poaching substantially reduces endangered animal populations, legal, for-profit, private farming does the opposite. It has substantially increased the populations of the southern black rhinoceros and southern white rhinoceros. Recovery Plans In the United States and many other countries, recovery plans are often developed to aid in the recovery of the species. These recovery programs can be in situ (take place in the natural range of the species) or ex situ (in areas outside their natural range) and can involve.

Living within our environmental limits is one of the central principles of sustainable development. One implication of not doing so is climate change. Environmental sustainable development involves making decisions and taking action that are in the interests of protecting the natural world, with particular emphasis on preserving the capability of the environment to support human life. Environmental sustainable development is about making responsible decisions that will reduce your business' negative impact on the environment. It is not simply about reducing the amount of waste you produce or using less energy, but is concerned with developing processes that will lead to businesses becoming completely sustainable in the future.   Monitoring, analysis and management of environmental pollution in biodiversity  Monitoring analysis and Assessment discusses technical developments and data arising from environmental monitoring and assessment, principles in the design of monitoring systems, and the use of monitoring data in assessing the consequences of natural resource management and pollution risks. Monitoring analysis designed to estimate exposure both at the individual and population levels, and also focuses on the development of monitoring systems related to the management of various renewable natural resources in, for instance, environment ,agriculture, fisheries and forests.

Biodiversity is under serious threat as a result of human activities. The main dangers worldwide are population growth and resource consumption, climate change and global warming, habitat conversion and urbanisation, invasive alien species, over-exploitation of natural resources and environmental degradation. Species often become threatened or disappear when several of these factors are combined. The fragmentation of habitats decreases the size of populations and makes these more vulnerable to other factors.

Ecosystem functioning reflects the collective life activities of plants, animals, and microbes and the effects these activities feeding, growing, moving, excreting waste, etc. have on the physical and chemical conditions of their environment. (Note that functioning means showing activity and does not imply that organisms perform purposeful roles in ecosystem-level processes.) A functioning ecosystem is one that exhibits biological and chemical activities characteristic for its type. Ecologists abstract the essential features of an ecosystem into two compartments, the biotic and the abiotic. The biotic compartment consists of the community of species, which can be divided functionally into plant producers, the consumers that feed on producers and on each other, and the decomposers. The abiotic compartment consists of organic and inorganic nutrient pools. Energy and materials move between these two compartments, as well as into and out of the system. Comparing different ecosystems is likely to yield an unclear result because the response to variations in biodiversity cannot easily be distinguished from responses caused by variations in environmental and other factors. [biodiversity conferences USA] explained very well about Biodiversity & Ecosystem.

Flora is the plant life occurring in a particular region or time, generally the naturally occurring or indigenous, native plant life and Fauna is all of the animal life of any particular region or time. Both are collective terms, referring to groups of plant or wildlife specific to a region or a time period. To geographical groupings, environment also helps further their classification. For example, aquatic flora and fauna of a region refers to the plant and animal life found in the waters in or surrounding a geographic region. Conservation, The area of flora, fauna and biodiversity is quite interrelated. Flora and fauna forms a major part of biodiversity. India is a land of varied flora, fauna and biodiversity. India is one of the twelve mega-diverse nations of the World. Two of India's great mountain ranges, the Eastern Himalayas and the Western Ghats have been designated among the world's eighteen 'hotspots' of biodiversity. But In the last few decades we have seen a steady increase in the extinction rate of flora, fauna etc. all over world including India and so now, conservation of biological diversity is of paramount importance to the survival of man. Conservation of biological diversity leads to conservation of essential ecological diversity to preserve the continuity of food chains. The genetic diversity of plants and animals is preserved. It ensures the sustainable utilization of life support systems on earth. It provides a vast knowledge of potential use to the scientific community. A reservoir of wild animals and plants is preserved, thus enabling them to be introduced, if need be, in the surrounding areas. Biological diversity provides immediate benefits to the society such as recreation and tourism. Biodiversity conservation serves as an insurance policy for the future.

The Biodiversity Management Branch is responsible for the conservation and restoration of biodiversity within the City's boundary. A fundamental aspect to the branch’s work is to ensure that biodiversityand nature are mainstreamed into everyday life, which includes delivering tangible benefits to all communities. More specifically, this Biodiversity Management branch is responsible for conservationplanning, biodiversity management and alien species eradication. In the field of conservation planning, the City’s approved Biodiversity Strategy has resulted in the identification of a biodiversity network of sites that need to be secured to conserve a representative sample of the Cape Town’s unique biodiversity and, thus, promote sustainable development. Key functions of the Biodiversity Management branch include:

Healthy ecosystems are essential to increase resilience and agricultural production in the face of change. Production needs to be sustainable: capitalizing on biological processes and harvesting resources without compromising natural capital such as biodiversity and ecosystem services. A large number of the world’s poor rely directly on biodiversity and ecosystem services, and their livelihoods would be affected first and foremost by biodiversity loss.A vastly broader share of the human population would be affected by a decrease in the provision of ecosystem services related to food production, nutrition, water and sanitation.
