Food security,an important standard of people’s life quality ——a reflection of China and Israel

Food security has been an international topic for many years.Especially in a large country with a huge amount of people such as China,food security is closely related to the level of the national economic development.But it is not optimistic that the crisis of global food security has not been solved,instead it is increasingly serious.

In recent years,the climate crisis is more and more serious,and it is one of the biggest challenges the food security facing now.Temperature rise cause problems like plant diseases and insect pests and extreme weather such as drought,flood are affecting global agricultural production.How to ensure food security has become a big problem to China and even the whole world. In general,China's food security has the follow problems.

To start with,the food supply in tight balance.As is known to all,we have only 9% of the world's arable land,but we need to use the food grow on that area to feed almost 22% percent of the people in the world.It is obvious that how great pressure we under.Although we do not have to worry about food since we born,there still some people who live in remote mountain village always stand hunger.The crop yield of many parts is not high,once any big disaster happened,stored food could not resist one year's living.

Besides,food price is increasing everyday,which cause the hunger to grow.After new China founded,food prices continued to rise till now,especially in recent years.At the same time,citizens' average income did not receive corresponding improvement,so that now people's living pressure is bigger than before.

What's more,natural disasters has influenced the quantity and the quality of food badly in recent years.Investigation shows that from 1999 to 2006,Chinese cultivated area had reduced from1.697billion acres to1.572billion acres,average annual it reduced 17.88 million acres during those seven years.The excessive use of pesticides not only affects the quality of soil,but also damages the safety of food,which cause heavy losses to people's health.We should attach great importance to environmental protection.

Compared with Israel,we need to learn and improve in many parts.They overcome many problems such as the low rainfall,infertile soil,and high temperature in summer,cultivate a variety of fruit,walnut,breeding fish and dairy.They also use undrinkable water in desert develop health and harmless vegetables.Israel has made many contributions for Global food security,many of which are very useful to China's agricultural development.

The most important invention is drip irrigation technology.Israeli use slow and balance drip irrigation on the most effective part to create huge growth of crop yield.The equipment has an ability of self purification,which make sure the quality of water as well as food security.

Another valuable creation is GrainPro Cocoons,which used to keep food fresh.Developing countries' farmers tend to deposit the crops in original basketball or bag,but the storage method can't partition hungry pests and subtle pollutants.Research shows that 50%of grain harvest and 100%of soy crop harvest are lost because of mycete and pests.Using the Cocoon can solve the problem effectively,even in extreme hot and humid environment.

In addition,biological control of pests is worth mentioning.An Israeli company called Bio-Bee cultivated some beneficial insects and mites to control pest instead of chemical pesticide.The method could produce real green food.

Apart from the above,Israeli also invented many useful ways to improve the environment condition and the quality and quantity of food. Every year,the food exported from Israel supports many people’s life.

As the most populous nation,food is very important.We should not only let every Chinese eat their fill,but also let them eat safely.We should learn from Israel,develop more advanced and safe technology instead of traditional agricultural technology.Always remember that food security is more important than everything.

Now we should study hard to grasp theoretical knowledge.On day in the future,when we become the main force of our country,we must assume this responsibility of food security,spare no effort to give our wisdom and strength.
