Interpretação de texto em inglês - Future Foods Discourse Marker

The world's population is increasing at a fast rate, and it is estimated that about one billion people in the world go hungry every day. Some  people say that genetically modified (GM) food is the answer to this problem, however the use of a new technology always involves risks and people have to consider many arguments before they make their choices. Let's explore one aspect related to GM food: how to battle bugs. Can genetic modification help farmers keep bugs at bay and therefore avoid pests and diseases? 

A) Instead of spraying crops with pesticides and fungicides, scientists in Peru are testing a cheap and safe alternative. They've released chickens into the local potato fields to eat up the Andean potato weevils - a notoriously damaging pest. 
This method saves farmers money and time, and reduces the potential hazards of handling powerful chemicals.

B) Instead of spraying crops with expensive and potentially hazardous chemicals, researchers are trying to create plants that resist problems by themselves. 
Currently, farmers have to spray potatoes once a week to avoid the devastating late blight disease. But there are wild Andean potatoes that aren't affected by blight. If scientists can transfer their genes to other potato varieties in the lab, the GM super-spuds won't need spraying with fungicides.
