Reading 1 "Wild Food Crops to be 'Rescued'

Scientists have announced a plan to collect and store the wild plant relatives of essential food crops, including wheat, rice, and potatoes. The project, coordinated by the Global Crop Diversity Trust, will collect and catalogue seeds from across the globe. The aim is to safeguard valuable genetic traits that the wild plants contain, which could be bred into crops to make them more hardy and versatile. This could help secure food supplies in the face of a changing climate. All of the plant material collected will be stored in seed banks in the long term, but much of it will also be used in pre-breeding trials to find out if the wild varieties could be used to combat diseases that are already threatening food production. Dr Paul Smith is head of the Millennium Seed Bank at London's Royal Botanic Gardens, Kew, which is playing a key role in the project. "There is a real sense of urgency about this," he told BBC News. "For some of these species, we may just get this one bite of the cherry, because so many of them are already threatened [with extinction] in their natural habitats." The hope is that the wild relatives of food crops will help plant-breeders to "correct for", not only a changing climate, but plant diseases and loss of viable agricultural land. Cary Fowler, executive director of the Global Crop Diversity Trust explained: "All our crops were originally developed from wild species- that's how farming began." But they were adapted from the plants best suited to the climates of the past. "Climate change means we need to go back to the wild to find those relatives of our crops that can thrive in the climates of the future."

Statements 1 through 10 (on your answer sheet circle + if the statement is true, - if it is false)
1. Scientists haven't begun to collect anything yet.
2. Scientists will be collecting wild relatives of domesticated crops.
3. Many of these wild plants are in danger of dying out.
4. All of the seeds will be stored and studied as historical examples of genetic diversity. 5. The project's goal is to use the wild plants to genetically strengthen current crops.
6. The project will collect wild variants only of wheat, rice and potatoes.
7. The Millennium Seed Bank is the leader of the project.
8. Scientists will use the stored seeds to research solutions to current food-crop problems.
9. Dr. Smith feels that there is no reason to rush into this project.
10. This project could reverse the effects of climate change.
