FAO: two kinds of livestock are extinct every week

Introduction: according to the FAO, the number of livestock and crop species in the world is decreasing rapidly On average, two species of livestock are extinct every week In the past 15 years alone, 300 of the 6000 livestock species identified by FAO have disappeared, and 1350 livestock species are still in danger of extinction FAO believes that this situation will affect the safety of human food Food and Agriculture Organization of the United Nations reported that the variety of crops disappeared quickly In the past, 10000 plants were used as food by human beings, but now 90% of human food is provided by less than 120 crops At the beginning of the 20th century, 90% of the existing food crops had disappeared The group warns that food needs will double in the next 30 years due to the growth of the world's population According to a report published by the FAO, biodiversity can guarantee the safe supply of food and livestock to human beings, and it is very dangerous to rely on only a few varieties Because only a few kinds of livestock and crops are difficult to resist natural disasters such as pests and drought Only by relying on biological diversity can farmers respond appropriately to unexpected environmental changes Hartwig, assistant director-general of the FAO, said that the diversity of organisms makes ecosystems more resistant to climate change The biggest threat to livestock diversity is the export of livestock and food from developed countries to developing countries, leading to the reduction of local breeds Due to the high output of imported varieties, local varieties are gradually replaced by imported varieties At the same time, the industrialization of agriculture and the globalization of economy also lead to the decrease of the diversity of animals and plants If biodiversity continues to decline, the risk of large quantities of food produced by humans relying on only a few varieties will increase, cadillo said FAO is convinced that the adoption of more plant and animal varieties is the best way to preserve biodiversity The organization has put forward a global strategy to manage livestock and crop resources Its goal is to preserve existing varieties, develop and improve these varieties and accelerate their application in agriculture At the same time, it also needs to retain less excellent varieties to protect its genetic resources (author:) share to feed Weibo share to:
