According to Malhotra, N. biodiversity is a fragile thing, vulnerable to all threats that might happen. Even though biodiversity supports and provides all things that all the life on earth needed, we cannot control those problems that might happen in just a snap. Right now biodiversity was facing a huge problem and threats and those threats are comes from many sources some sources is from us, humans and some are natural. And based on Malhotra N. the real problem that we are facing was the conservation
how evolution generates biodiversity through the process of natural selection and speciation, we must first understand and define those terms. Oxford dictionaries define natural selection as "the process whereby organisms better adapted to their environment tend to survive and produce more offspring." Speciation is "the process in which new genetically distinct species evolve usually as a result of genetic isolation from the main population." (Speciation, 2008) Biodiversity is the variation of life
2.2. CONCEPT OF BIODIVERSITY It has been estimated that more than 50 million species of plants, animals and micro-organisms are existing in the world. Out of these, about 1.4 million species have been identified so far. Each species is adapted to live in specific environment, from mountain peaks to the depth of seas, from polar ice caps to tropical rain forests and deserts. All this diversity of life is confined to only about one kilometre thick layer of lithosphere hydrosphere and atmosphere which
Biological resources provided by the Earth play essential role in economic and social development of the humans. Therefore, it is of great importance to acknowledge an enormous value of biological diversity both to present and future generations. However, ecosystems and species have never been under such threat as they are nowadays. Loss of species caused by human activities continues at an alarming rate (CBD, 2014). As a reaction to the seriousness of the problem, in November 1988 the United Nations
The global community has realized the value of biological diversity in the last quarter of 20th Century more than ever before for the sustainability of life on earth. Biological diversity is also understood as a source of food, good health and its indispensability for human development. The pace of destruction of biological diversity due to different anthropogenic reasons and rapid advancements in bio-prospecting has triggered countless concerns amongst the global leaders and policy makers. The Convention
Biological warfare effects on Biodiversity Biological weapons are considered as one of the most destructive known weapons. It is used to deliberately cause epidemics among humans and to destroy the environment including water, air and soil. It is also targeting agricultural crops and livestock. Examples of diseases used in biological warfare: anthrax, smallpox, plague, cholera, and avian flu. In addition to the catastrophic effects of biological weapons, the danger lies in their low cost, rapid
environment. The concept of 'Sustainable Development', which aims at striking a balance between preserving the environment and achieving economic progress, has emerged as the biggest challenge for mankind today. It was recognised as an issue of great importance in the last decades of the 20th century and continues to be so in the 21st century as world population burgeons and natural resources across
and non – participatory governance of protected area have rigorously affected livelihoods of an indigenous people who are predominately dependent on natural resources (Amin, 2015; West, 2006; Wells 1995). In the context of Nepal, the notion of biodiversity conservation held constraining perspective on the protection of flora and fauna. Therefore, several conflicts between park – people in protected areas are presented in literature case studies of Nepal (Nepal, 1992; Limbu, 2003; Pant 2012; Gyawali
Most tourists make "cultural tours" where they visit important destinations. Paro, Thimphu, Punakha, Wangdue and Jakar are popular destinations. Further on, the unknown area of Gangung (bird paradise, excellent wildlife) and East Bhutan are just open to tourism. If you are an adventurer and want to explore the unexplored east of Bhutan, this is the place for you. This unique and still untouched part of the country offers the best experience.

National Forest Policy (NFP) which formulated in 1978 and revised in 1992, is endorsed by National Land Council (NLC) has established Permanent Reserved Forests (PRF) (Tempatan, 2010) . The objectives of NFP is conserve and manage the nation’s forest based on the principles of sustainable management and to protect the environment as well as to conserve biological diversity, genetic resources, and to enhance research and education in Malaysia. According to this policy mangrove forests, both peat
