the world, there are around 2.35 billion acres of highly saline(含盐的) land. and the number is increasing because of rising sea levels and climate change.“probably only a small part of the worlds saline land could be brought into production with seawater rice，but that would still have a very important effect on food security，” even r. pay, a senior analyst, said.yuan told xinhua that one of the varieties of rice grown in dubai produced over three tons, per acre, which yuan said was beyond expectations.rice is the basic food in many parts of the world. about 90% of rice consumption is from asia, but demand in africa and latin america is on the rise.a climate change researcher said the successful experiment could potentially benefit many countries. “this is a fantastic development, which is likely to have a good effect on agricultural resource and waterpoor countries, particularly in north africa region.”even though the cost of growing salttolerant rice is still high，it will also have strategic value once its commercialized.【解题导语】本文主要介绍了在“杂交水稻之父”袁隆平带领下的科学家们进行了在沙子和海水中种植水稻的试验。1what has caused the scientists to find new ways of growing rice?athe increase of rice consumers.bthe high
