32、is increases production because more coffee bushes can be planted if there arent any trees.With increased production come increased profits.Unfortunately,deforesting for coffee production immediately decreases local-wildlife habitat.Native birds nest and hide from predators(捕食者)in the tall trees and
33、 migrating birds rest there.Furthermore,in the long term,the full-sun method also damages the ecosystem because more chemical fertilizers and pesticides are needed to grow the coffee.The fertilizers and pesticides kill insects that eat coffee plant,but then the birds eat the poisoned insects and als
34、o die.The chemicals kill or sicken other animals as well,and can even enter the water that people will eventually drink.Fortunately,farmers in Central and South America are beginning to grow more coffee bushes in the shade.We can support these farmers by buying coffee with such labels as shade grown
35、and bird friendly.Sure,these varieties might cost a little more.But were paying for the health of the birds,the land,ourselves,and the planet.I think its worth it.31.What is the main idea of this passage?A.Farmers are changing the way they grow coffee.B.Coffee is becoming more expensive to produce.C

40、(营养不良)and poverty.he said.Research is needed to solve food production,land degradation(贫瘠化)and environmental problems.Secure local food supplies led to economic growth which is turn,slowed population growth.Dr.Fischer painted a picture of the worlds ability to feed itself in the first 25 years,when
41、the worlds population is expected to rise from 5 X to X billion people.He said that things will probably hold or improve but therell still be a lot of hungry people.The biggest concentration of poor and hungry people would be in sub-Saharan Africa and southern Asia in ,similar to the currenti patter
42、n.If there is any change,a slighe improvement will be seen in southern Asia,but not in sub-Saharan Africa.The major improvement will be in East Asia,South America and South-East Asia.The debeloping world was investing about 0.5%,or $8 billion a year,of its agricultural gross domestic product(GDP)on
43、research and developed world was spending 2.5% of its GDP.Dr.Fischer said more was needed from all countries.He said crop research could produce technologies that spread across many countries,such as wheat production research having spin-offs(有用旳副产品)for Mexico,China or India.Technologies still need
44、to be refined for the local conditions but a lot of the strategic research can have global application,so that money can be used very efficiently.Dr.Fischer said.Yields of rice,wheat ad maize(玉米)have grown impressively in the past 30 years,especially in developing countries.For example,maize product
45、ion rose from 2 to 8 tonnes per hectare between 1950 and 1995.But technologies driving this growth such as high-yield varieties,fertilizers,and irrigation,were becoming exhausted.If you want to save the land for non-agricultural activities,for forests and wildlife,youre going to have to increase yie
