BIODIVERSITY
Biodiversity is made up of two words that is biological and diversity. Biological word is related to life and diversity is linked with variations or changes. In simple terms, we can say that biodiversity means the variations in life. Biodiversity is defined as whole life that exists on earth planet including animals , plants, fungi and micro-organisms as well as the associations among them including their eco-system (IUCN, 2010).
Classification of biodiversity
The biodiversity can be of following types (Ontario Biodiversity Council, 2011):-
1.Genetic Biodiversity:- It includes variability occur between the genes among the different species.
2.Species Biodiversity:- It is defined as alterations in different organisms in specific area.
3.Eco-system Biodiversity:- This term refers to variations in the interactions of species that they form among them.
Importance of Biodiversity
Biodiversity is essential for the survival of every species on the earth because it maintains the equilibrium in the environment . Its importance are as follows:-
1. Plants provide food and clean environment to humans and give oxygen for their respiration.
2. Forests provide homes to several wild animals and also help in preventing soil erosion as well as floods.
3. Paper, wood, textiles, fibres are obtained from biological resources and thus helpful in running the industries which can increase the world economy.
4. many medicines are extracted from different plants and animals which are helpful in treating many deadly diseases in humans. for instance:- Quinine obtained from Cinchona tree is helpful in treating malaria. Penicillin(antibiotic) is obtained from soil fungus.
5. Biodiversity provides aest...

Forests cover 31% of the land area on our planet. They produce vital oxygen and provide homes for people and wildlife. Many of the world’s most threatened and endangered animals live in forests, and 1.6 billion people rely on benefits forests offer, including food, fresh water, clothing, traditional medicine and shelter (drug war facts, Page 1).
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.
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.
We depend on plants to obtain our oxygen. Plants produce glucose that assists in its living and growing and we contribute by releasing carbon dioxide. In order for us to live, we need the oxygen that plants produce by making glucose.
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.
Environmental issues affect every life on this planet from the smallest parasite to the human race. There are many resources that humans and animal needs to survive; some of the most obvious resources come from the forests. Forests make up a large percentage of the globe. The forests have global implications not just on life but on the quality of it. Trees improve the quality of the air that species breath, determine rainfall and replenish the atmosphere. The wood from the forests are used everyday form many useful resources. Moreover, thinning the forests increases the amount of available light, nutrients and water for the remaining trees. Deforestation (forest thinning) is one of the most critical issues of environmental problems that are occurring today.
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.

Without plants, none of this energy could be produced and the herbivores that humans consume would not exist. The cells in plants also undergo cellular respiration, which creates the byproduct oxygen.
Biodiversity loss can lead to extinction, and hurt human life. It is our responsibility to take care of the environment. We bring in machines that harm the environment and destroy animal life. We need to limit ourselves on how much land and resources we consume. There are major issues that are causing species to become extinct and hurt our way of life and other animals do to the change in food chain.
Scientists have begun to say that we have to do more to protect our ecosystem, because our very existence is depending upon it. When the ecosystem is not functioning properly the continuation of plant, animal and human life ecosystems would be impossible. Life cycles can not function without ecosystems. The ecosystem provides us with clean air, water, habitats for fish and other services. They also aid in the mod...
Forests are vital for life and have many important functions. They are home to millions of species and protect soil from erosion. Along with this they produce oxygen which is vital for human life, store carbon dioxide and help control climate. They also provide humans with shelter, food and medicines vital for life.
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.
...at we need. Clean up the rivers and streams, lakes and oceans. Reduce the use of chemicals and pesticides. But society must do something, even if only donating money to an organization who does. Just do something to help, before even more animals disappear, before all the fish and forests are gone, before the earth has so little diversity that only humans remain.
