第一篇：Why Buy Shade-Grown Coffee?
When people argue about whether coffee is good for health, they're usually thinking of the health of the coffee drinker. Is it food for your heart? Does it increase blood pressure? Does it help you concentrate? However, coffee affects the health of the human population in other ways, too.
Traditionally, coffee bushes were planted under the canopy(树冠)of taller indigenous(土生土长的)trees. However, more and more farmers in Latin America are deforesting the land to grow full-sun coffees. At first, this increases production because more coffee bushes can be planted if there aren’t 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 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 also 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" and "bird friendly." Sure, these varieties might cost a little more. But we're paying for the health of the birds, the land, ourselves, and the planet. I think it's worth it.

第二篇：More Rural Research is Needed
Agricultural research funding is vital if the world is to feed itself better than it does now. Dr. Tony Fischer, crop scientist, said demand was growing at 2.5% per year but with modern technologies and the development of new ones, the world should be able to stay ahead.
“The global decline in investment in international agricultural research must be reversed if significant progress is to be made towards reducing malnutrition(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 world’s ability to feed itself in the first 25 years, when the world’s population is expected to rise from 5 X to X billion people. He said that things will probably hold or improve but there’ll 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 2020, similar to the currenti pattern. 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.
