Organic – A Concept for and Feeding a Growing Population

1st HiPP Scientific Symposium on Organic Food

Today, organic agriculture were based on observation of nature and chair of the symposium, the is regarded as a more sustainable and respect for natural laws and central working principle of organic alternative to conventional farming, subsequently transformed in practical farming is the ideal of a closed cycle which is a main contributor to green- farming methods by organic pioneers.1 (fi g. 1): plants grown on the soil of a house gas production, environmental Since then, and food farm are either used as foodstuff or pollution, soil quality decline, and bio- production developed into a worldwide entered back in the cycle as , diversity loss.

Moreover, organic food contains less residues that may cause detrimental health effects even in very low concen- trations, especially in fetuses and children. Aside from these advan- tages, organic agriculture has proved to be more cost-effi cient than con- ventional agriculture. This is particu- larly the case if the true costs of conventional farming are taken into account. Most importantly, organic food production is regarded as vital to safeguard a safe and nutritious food supply for the growing world population in the years to come. Source: Prof. Carola Strassner
