Marwan abd, Beirut’s mayor, estimated that the explosion would cost between $3 billion and $5 billion, equivalent to nearly one tenth of Lebanon’s GDP. In addition, 300000 people have been left homeless. However, the storage granary at the port of the incident was seriously damaged. The granary stored 85% of Lebanon’s strategic grain reserve. After the destruction, Lebanon’s Grain Reserve has been less than a month. < / P > < p > before the explosion, Lebanon was in a financial crisis. The cause was a problem with the exchange market in Lebanon. Lebanon is one of the few countries in which there are more people in Lebanon than in Lebanon. Therefore, remittances from overseas Chinese play an important role in stabilizing the economy of Lebanon. In recent years, however, the price of oil and gas in the periphery has decreased due to the fluctuation of oil and gas. At the same time, many rich people in Lebanon have transferred their US dollar assets abroad, which is estimated to be more than US $30 billion, equivalent to Lebanon’s fiscal reserves. Once in and out, the local currency of Lebanon has been difficult to support. Since September last year, Lebanon has declared an economic emergency due to the turmoil in the foreign exchange market. Since then, Lebanon has fallen into severe inflation. In the past 10 months, the Lebanon pound has depreciated by more than 80% to 9000:1 against the US dollar. The government of Lebanon plans to set the exchange rate of the pound against the US dollar at 4297:1 by 2024, while the official exchange rate for daily necessities will remain at 1500:1. < / P > < p > the double exchange rate has thrown Lebanon’s foreign exchange market into more chaos. Importers are afraid to import in order to avoid exchange rate risk. In the first quarter of this year, imports fell by 40%, which directly affected the supply chain of Lebanon. For 10 months, soaring prices and a devalued currency have taken a wave out of Lebanon. The World Bank estimates that 45% of the population in Lebanon will be below the poverty line this year. Of the many crises facing Lebanon, the biggest challenge at present is to eat. Lebanon relies on imports for 80% of its food supply, mainly from Russia and Ukraine. However, due to the epidemic situation, Russia has temporarily stopped grain exports and Ukraine’s exports have also decreased. Just at this time, the explosion destroyed Lebanon’s granary and destroyed 85% of its strategic reserves. < p > < p > in fact, to grow food, Lebanon is truly a “land of milk and honey”, with the best conditions in Arab countries. However, as the hometown of Carthage, the people here have little enthusiasm for growing grain. The 15 year internal war in Lebanon has just ended, followed by the cedar revolution, the conflict between Lebanon and Israel, the war between the Lebanon army and Fatah, and the conflict with the Amal forces. The economic ecology of Lebanon has been destroyed time and again, and there is no solid environment for agricultural farming. Therefore, although Lebanon has a good agricultural economic endowment, it can not solve the problem of food self-sufficiency for a long time and can not support 6 million people. However, the exchange rate crisis has led to rising prices, which has exacerbated the food crisis. As early as may, Lebanon’s prime minister, diab, warned in the Washington Post that Lebanon was on the verge of massive food shortages and starvation. The reason is the superposition of political corruption, financial crisis and epidemic isolation measures. Now, coupled with the destruction of the granary, the first thing to solve is the problem of feeding 300000 displaced Libyans. Since the financial crisis in Lebanon last year, there have been large-scale protests, which have not stopped. The main appeal of the protestors is “anti central bank” and the establishment of expert government to solve the economic crisis. Some of the demonstrations also targeted high-level government. Although the explosion has reduced Street activities, the voice of accountability has appeared. The relevant statements of all parties in the political arena of Lebanon have vaguely pointed to the opposite. The factions in the political arena of Lebanon, which have already constrained each other, have greatly increased the possibility of political disputes. In this situation, the effect of disaster relief and reconstruction is not optimistic. In addition, due to the cooperation between the Central Bank of Lebanon and the United States government, the Central Bank of Lebanon has frozen the assets of its allies in Lebanon and abroad, and has formed enmity with the United States and its agents in Lebanon. < / P > < p > and the port where the big explosion occurred was under control, which inevitably increased the suspicion of foreign enemies. In fact, the prime minister’s explanation of the cause of the explosion is not consistent with that of the prime minister with a Sunni background. The history and reality of Lebanon are full of sighs. Facing the huge crisis of people’s livelihood caused by the explosion, it is incumbent on us to help. At present, some countries and international organizations, including China, have indicated that they will provide assistance. This is not only a manifestation of international morality, but also a necessary measure to prevent Lebanon from becoming a “powder keg” in the Middle East again.
