| dc.description.abstract | After World War II, the globe has been stopping into more peaceful period comparatively. With the obviously improving science technology and medical treatment, global population broke through 3 billion in 1960， and it is still growing in an average of 1 billion every 13 years, eventually it had reached 7.3 billion in 2016. According to United Nation published in 2015, the global population is estimated to reach 8.5 billion in 2030, 9.7 billion in 2050, and 11.2 billion in 2100.
According to the research, the speed of the population growth will gradually slowdown, but the trend that total population’s growing remains the same, and under the condition that the global land sources is limited, it will initially impact on human’s basic need. “Physiology need is the most basic need.” The principle aim is how to survive, and the key to basic source is food!
After experiencing the global food crisis in 2008, and the improving of medical technology, people in developed countries have now gradually turned to desirability of eating healthily than eating adequately in the past. And in the past, we used too much chemical fertilizer on food increasing. Though it actually achieved food redoubled, and has improved food lacking problem. However, in the meantime the accumulation absorbed by eating or through food chain has gradually caused civilized diseases. Under the consciousness of health, we begin to trace back to the food sources, therefore organic agriculture appeared!
Organic agriculture is to recentralize the wasted material that is produced during the process and use ecological engineering to maximize its surplus value then returns back to the nature ecosystem. To reduce the waste in one-time process, which adapts to the so-called “recycled-ecomomic”3R rules , “Reduce”, “Reuse”, “Recycle”!
(Because the source of organic fertilizer is difficult to acquire currently) The purpose of this study is to search for a way to produce massive amount of organic fertilizer, to reduce the wasted material, and create surplus value, furthermore spread to the ecological circulation and encourage more farmers to use organic fertilizer, produce more organic green products, make people eat more healthy and more relieved! | en_US |
