The term biodiversity refers to the variety of life on Earth at all its levels, from genes to ecosystems, and the ecological and evolutionary processes that sustain it. Biodiversity includes not only species we consider rare, threatened, or endangered, but every living thing—even organisms we still know little about, such as microbes, fungi, and invertebrates. Biodiversity is important everywhere; species and habitats in your area as well as those in distant lands all play a role in maintaining healthy ecosystems.

Despite the numerous benefits and advantages gotten from biodiversity, it 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 urbanization, invasive alien species, over-exploitation of natural resources and environmental degradation.
Biodiversity action plan
A biodiversity action plan (BAP) is an internationally recognized program addressing threatened species and habitats and is designed to protect and restore biological systems. The original impetus for these plans derives from the 1992 Convention on Biological Diversity (CBD). As of 2009, 191 countries have ratified the CBD, but only a fraction of these have developed substantive BAP documents.
The principal elements of a BAP typically include: (a) preparing inventories of biological information for selected species or habitats; (b) assessing the conservation status of species within specified ecosystems; (c) creation of targets for conservation and restoration; and (d) establishing budgets, timelines and institutional partnerships for implementing the BAP.
Summary
Pakistan spans a number of the world’s ecological regions with its latitudinal spread and immense variations in altitude. These regions include the coastal mangrove forests of the Arabian Sea as well as some of the highest mountains of the world, where the western Himalayas, Hindu Kush and Karakoram ranges meet. This diversity encompasses a variety of habitats that support a rich biodiversity. A number of animals and plants have become endangered due to over-exploitation and loss of natural habitat. Rapid human population growth puts increasing pressure on the country’s natural resource base. Increased poverty has forced rural people to exploit biodiversity at unsustainable rates. Deforestation, overgrazing, soil erosion, salinity and waterlogging have become major threats to Pakistan’s remaining biodiversity. The continuing loss of forest habitat, with its associated fauna and flora, will have serious implications for the nation’s other natural and agricultural ecosystems. Protected areas have been established for in-situ conservation of biodiversity.
A wide range of laws also exists relating to conservation of various components of biodiversity. The key to protecting the biological diversity of Pakistan is involving local communities and obtaining support from relevant institutions in sustainable use initiatives. The Government of Pakistan recognised the importance of these measures in the preparation of the National Conservation Strategy (1992) and in becoming a party to the Convention on Biological Diversity (CBD) in 1994. The Biodiversity Action Plan (BAP), endorsed by the Pakistan Environmental Protection Council (PEPC) in 1999, calls for government agencies, local communities and NGOs to work together as partners in biodiversity conservation.
These are the most critical issues for biodiversity conservation in Pakistan:
The need for associated policy and institutional reforms and institutional strengthening; integration of biodiversity conservation measures into sectoral initiatives; better understanding of all aspects of biodiversity and effective means for ensuring their sustainable use; developing community-based biodiver

Energy Flow and Nutrient Cycle - Environment Science Community and EcosystemPreetiSinha52
Energy Flow and Nutrient Cycle - Environment Science Community and Ecosystem Concept
Energy flows through an ecosystem from producers to consumers. Energy flows from one trophic level to the next.
(troph = feeding)
Nutrients (matter) cycle in an ecosystem.
The processes of photosynthesis and aerobic respiration are important in nutrient cycling and energy flow.
Environment literally means surrounding and everything that affect an organism during its lifetime is collectively known as its environment. In another words “Environment is sum total of water, air and land interrelationships among themselves and also with the human being, other living organisms and property”. It includes all the physical and biological surrounding and their interactions.
Environmental studies provide an approach towards understanding the environment of our planet and the impact of human life upon the environment.
Thus environment is actually global in nature, it is a multidisciplinary subject including physics, geology, geography, history, economics, physiology, biotechnology, remote sensing, geophysics, soil science and hydrology etc. Scope of Environmental Science Environmental science is a multidisciplinary science whose basic aspects have a direct relevance to every section of the society.
Its main aspects are:
• Conservation of nature and natural resources.
• Conservation of biological diversity.
• Control of environmental pollution.
• Stabilization of human population and environment.
• Social issues in relation to development and environment.
• Development of non-polluting renewable energy system and providing new dimension to nation’s security. Importance of Environmental Science Environment belongs to all the living beings and thus is, important for all.
Each and every body of whatever occupation he or she may have, is affected by environmental issues like global warming, depletion of ozone layer, dwindling forest, energy resources, loss of global biodiversity etc.
Environment study deals with the analysis of the processes in water, air, land, soil and organisms which leads to pollute or degrade environment. It helps us for establishing standard,Environment and Ecology for safe, clean and healthy natural ecosystem.
It also deals with important issues like safe and clean drinking water, hygienic living conditions and clean and fresh air, fertility of land, healthy food and development. Sustainable environmental law, business administration, environmental protection, management and environmental engineering are immerging as new career opportunities for environment protection and managements.
Need for Public Awareness With the ever increasing development by modern man, large scale degradation of natural resources have been occurred, the public has to be educated about the fact that if we are degrading our environment we are actually harming ourselves.
To encourage meaningful public participation and environment, it is necessary to create awareness about environment pollution and related adverse effects. The United Nations conference on Environment and Development held in Rio-de-Janeiro, followed by Earth summit on sustainable Development have high-lighted the key issues of global environmental concern and have attracted the general public towards the...
Ecology derived from two Greek word “oikos” means house, habitation or place of living & “logos” means study.
Definition: Ecology is the study of interrelationship between living organism and their physical and biological environment.

"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.
Micro RNA genes and their likely influence in rice (Oryza sativa L.) dynamic ...Open Access Research Paper
Micro RNAs (miRNAs) are small non-coding RNAs molecules having approximately 18-25 nucleotides, they are present in both plants and animals genomes. MiRNAs have diverse spatial expression patterns and regulate various developmental metabolisms, stress responses and other physiological processes. The dynamic gene expression playing major roles in phenotypic differences in organisms are believed to be controlled by miRNAs. Mutations in regions of regulatory factors, such as miRNA genes or transcription factors (TF) necessitated by dynamic environmental factors or pathogen infections, have tremendous effects on structure and expression of genes. The resultant novel gene products presents potential explanations for constant evolving desirable traits that have long been bred using conventional means, biotechnology or genetic engineering. Rice grain quality, yield, disease tolerance, climate-resilience and palatability properties are not exceptional to miRN Asmutations effects. There are new insights courtesy of high-throughput sequencing and improved proteomic techniques that organisms’ complexity and adaptations are highly contributed by miRNAs containing regulatory networks. This article aims to expound on how rice miRNAs could be driving evolution of traits and highlight the latest miRNA research progress. Moreover, the review accentuates miRNAs grey areas to be addressed and gives recommendations for further studies.
