As a “young emerging economy,” Taiwan cannot afford to remain outside the global community in combating climate change, President Ma Ying-jeou (馬英九) said yesterday at the first sustainable green technology symposium in Taipei.
“In the past 100 years, humans have focused on rapid economic and technological expansion. However, these have brought with them environmental consequences that we must address today,” Ma told the audience.
The future of technology, he said, lies in sustainable development.
The forum was hosted by the National Taiwan University, which invited Taiwanese specialists who work both abroad or locally to discuss the trends in green technology.
Ho Chih-ming (何志明), director of the Institute for Cell Mimetic Space Exploration at the University of California, Los Angeles, said that 200 years ago, humans never had to think about sustainability, as the ecosystem was balanced and could sustain human activity without much change
However, as a result of population increase and modernization, human needs are now tilting the system, he said.
“As such, we can only reach sustainability with the assistance of technology. After all, I don’t think people are willing to go back to the living standards that obtained 200 years ago,” he said.
Tackling the rapid depletion of oil and coal sources through reliance on sustainable energy — including wind power, fuel cells and nuclear energy — was also discussed during the symposium.
Promising global energy alternatives includes cellulosic bioethanol, said Daniel Wang (王義翹), a professor in chemical engineering at the Massachusetts Institute of Technology.
“We are badly in need of oil alternatives. We are not using corn as fuel because it is economically feasible, we are using it because we need it,” Wang said, adding that while “no country in the world [could] afford using edible resource, such as corn, to make ethanol … cellulosic biomasses such as agricultural residues, trees and grass represent great opportunities as feedstock for conversion [although] many technological challenges lie ahead.”
While scientists may devise advanced technology to help us live better, humans still depend on a healthy environment for their survival, the scientists said.
“The world needs a minimum of 0.3 trillion liters of freshwater for human consumption a day. I don’t believe we can rely only on technology to process that amount,” Ho said.
“The only way we can make the system work is if we sustain a sound, natural ecosystem and combine it with artificial industrial system — in other words, we have to work with nature,” he said.
LOUD AND PROUD Taiwan might have taken a drubbing against Australia and Japan, but you might not know it from the enthusiasm and numbers of the fans Taiwan might not be expected to win the World Baseball Classic (WBC) but their fans are making their presence felt in Tokyo, with tens of thousands decked out in the team’s blue, blowing horns and singing songs. Taiwanese fans have packed out the Tokyo Dome for all three of their games so far and even threatened to drown out home team supporters when their team played Japan on Friday. They blew trumpets, chanted for their favorite players and had their own cheerleading squad who dance on a stage during the game. The team struggled to match that exuberance on the field, with
Taiwanese paleontologists have discovered fossil evidence that pythons up to 4m long inhabited Taiwan during the Pleistocene epoch, reporting their findings in the international scientific journal Historical Biology. National Taiwan University (NTU) Institute of Ecology and Evolutionary Biology associate professor Tsai Cheng-hsiu (蔡政修) led the team that discovered the largest snake fossil ever found in Taiwan. The single trunk vertebra was discovered in Tainan at the Chiting Formation, dated to between 400,000 and 800,000 years ago in the Middle Pleistocene, the paper said. The area also produced Taiwan’s first avian fossil, as well as crocodile, mammoth, saber-toothed cat and rhinoceros fossils, it said. Discoveries

Whether Japan would help defend Taiwan in case of a cross-strait conflict would depend on the US and the extent to which Japan would be allowed to act under the US-Japan Security Treaty, former Japanese minister of defense Satoshi Morimoto said. As China has not given up on the idea of invading Taiwan by force, to what extent Japan could support US military action would hinge on Washington’s intention and its negotiation with Tokyo, Morimoto said in an interview with the Liberty Times (sister paper of the Taipei Times) yesterday. There has to be sufficient mutual recognition of how Japan could provide
