- Abstract (please use no less than 300 words to describe your proposal)
- Science Education through WiKimedia has been very effective. For example, if we talk of Conservation of Animal Resources for Sustainable Productivity, wast information is available on this subject on WiKimedia.To enlist some, a concise report is presented below.
"Perpetuation of annual production without causing disturbance in the ecosystem refers to sustainable productivity. The sun is the ultimate source of energy that reaches the earth in the form of sun light. This energy is trapped by the autotrophs, and then transmitted to higher trophic levels along the food chain. This transmission leads to the loss of 90 per cent energy at each trophic level. Therefore, production of animal resources along the food chain is, ecologically, very costly and needs great precisions and cares. However, this production is not only for the perpetuation of the biodiversity but also for providing animal protein to man. The food derived from the animals is most important component of human diet, as this is the only best source of protein. But other than man, there are several organisms / animals on earth to share this nutritional component.
Normally a man weighing 70 kg needs 1700 Kcals / d ; an Asian needs 2070 Kcals / d ; and a generous estimate is 3000 Kcals / d or 106 Kcals / year. The total arable land on earth is 4.56 x 109 ha. The solar input to the ecosphere can ensure production of various components in the food chain in differential yet fixed amount. For example, potential of earth for algae production is equal to meet the nutritional demands of 90 thousands billion persons, for grain to 380 billion persons, for prunes to 300 billion persons, for milk to 300 billion persons, for pork to 110 billion persons, and for eggs to 150 billion persons. These are the maximum limits of production which are regularly diminished by the diminishing arable land due to continuous change of land use from agriculture to other purposes. In coming years, more food will be required by the increasing human population. Therefore, there is going to be food crisis in the world. The over-exploitation of the animal resources has already shown adverse effects on sustainable animal resource production. The sustainability of terrestrial herbivores and aquatic faunal resources alone can support nutritionally 24 billion persons per annum. But this is possible only through adopting ecological principles of resource exploitation. Population growths in natural ecosystems follow the expected sigmoid patterns that, in turn, follow the principles of carrying capacity and a natural balance of populations. The optimum and sustainable harvest of these populations is possible through their scientific exploitation. The breeding and surplus stocks should be separated, breeding stock should be vigorously conserved / protected, proper regulations for animal harvest should be implemented and ecological needs of the exploited bioresources should be met. The annual harvest should be regulated on the basis of time, duration and extent of exploitation. If these principles are followed, animal bioresources of the world can provide a sustainable crop. The climate change has put multiple challenges on the animal productivity. Not only the primary productivity is going to be adversely affected, the secondary productivity will be lowered several folds due to multiple new ecological and physiological interactions. To sustain the global animal productivity, therefore, climate change should attract the attention of all concerned". This is one example. There are thousands of such cases which are of common interest to the public and the community.
