The study said that the output of frankincense will continue to decrease

According to the Bible, when Jesus was born, three doctors from the east came to Jerusalem with mysterious gifts to worship him The mysterious gifts presented by "Three Eastern doctors" are gold, frankincense and myrrh These three gifts represent the rarest and most precious tribute that can be given to the king at that time Among them, frankincense is a kind of gum resin with aromatic smell It is taken from the trees of frankincense in the desert and used for sacrifice in ancient times Now it is an important Chinese medicine Unfortunately, today, frankincense has become rarer and will continue to decline The researchers report their findings in the latest British Journal of Applied Ecology In recent years, frankincense trees have encountered difficulties in tree species reproduction Previously, ecologists believed that when traders obtained resin from such trees, trees themselves would weaken During the two years working in Ethiopia, researchers monitored 12 tree building plants, six of which had been extracted and six had not They found that the trees that had been extracted from SAP could reproduce as well as the trees that had not been extracted This eliminates the possibility that human interference is the main killer Instead, the biggest threats seem to come from grazing livestock, fires and an insect called the longicorn Among them, longicorn can drill holes and kill trees in the bark, so that tree building can only become the fuel of forest fires If these problems cannot be remedied in time, the team's model shows that the production of frankincense will be reduced by 50% in the next 15 years, which will be a heavy blow to the economies of frankincense exporting countries, Ethiopia and Eritrea.
