have today were once green lands,full of the plant life.One of todays biggest,deserts is in North Africa.However,in the,1st century BC farms in the North Africa,grew corn and wheat to make bread for,the whole city of Rome.How did this area,become desert?,FIGHTING GROWING DESERTS,Both weather and people can help,form a desert.Hot weather or very little,rain makes the land so dry that nothing,can grow.If people cut down or burn trees,and plants to make land clear for farming,the wind can blow the soil away and turn,the dry land into sand.Another big,problem is farming on land that is not,very good.,This poor land can very quickly turn into,desert,if it is farmed too much.One of the,biggest causes,however,is when people,take their animals to the same fields to,feed over and over,and the fields finally,lose all their nutrition.Because of these,problems,deserts are slowly taking over,green land in many parts of the world,including China.,However,we can fight the growing,deserts!In some parts of China people,are working to prevent desert from,expanding.In,Xinjiang,for example,some farmers are trying new scientific,farming methods.These methods make,it possible to use less land for crops,so farmers then can plant trees on the,rest of their land!,One,Xinjiang,farmer used only half of his,fields to grow the same amount of crops,as last year.On the other half of his land,he planted fruit trees.The work of people,like this is helping to fight the worlds,growing deserts.,Who is he?,贾思勰,北魏末年和 东魏时的著名农学家,为我国完整保存至今 最早的农书,齐民要 术,的作者。贾思勰
