The question is based on the following passage. A renewable-energy “oasis” scheduled to be built more may serve as a proving ground for new technologies designed to bring green living to the desert. The planned research center is part of the Sahara Forest Project which does not mean it will be built in Africa. The center is meant to be a small-scale version of massive green complexes that project managers hope to build in deserts around the globe. Experts are now examining arid sites in Australia, the U.S., the Middle East, and Africa that could support the test facility. “The Sahara Forest Project is a holistic approach for creation of local jobs, food, water, and energy, utilizing relatively simple solutions mimicking design and principles from natur.” said Frederic Hauge. For instance, special greenhouses would use hot desert air and seawater, make fresh water for growing crops, solar energy would be collected to generate power, and algae pools would offer a renewable and easily transportable fuel supply. In addition, planting trees near the complex would trap atmospheric greenhouse gases such as carbon dioxide while restoring any natural forest cover that has been lost to drought and timber harvesting. “From my perspective as an environmentalist, this could be a game changer in how we produce biomass for food and energy, and how we are going to provide fresh water for the future, “Hauge said. But not all experts are as enthusiastic about the project. In terms of the reforestation plans. “Trying to grow trees in the Sahara desert is not the most appropriate approach,” said a forest ecologist at the University of California. After all, even though it was literally green in the past, the Sahar was never heavily forested. What does the word "it"in "... which does not mean it will be built in Africa."(paragraph 1, sentence 2) refer to?
