A warmer world is going to be a sicker world for everything
from trees to marine life to people, according to a new report by a
panel of U.S. scientists. But opponents remain unconvincing there is 【S1】______
sufficient evidence to support the conclusion.
A team of researchers led by Drew Harvell at Cornell University
have completed a two-year study into climate-disease links. "That is 【S2】______
most surprising is the fact that cli mate sensitive outbreak are 【S3】______
happening with so many different types of pathogens—viruses,
bacteria and parasites (寄生虫)—as well in such a wide 【S4】______
range of hosts including corals (珊瑚虫), oysters, land plants
and birds," Harvell says.
the Co-researcher Richard Ostfeld, an animal ecologist at
Institute of Ecosystem Studies, adds, "This isn't just a
question of coral bleaching for a few marine ecologists, or just 【S5】______
a question of malaria (疟疾) for a few healthy officials—the
number of similar increases in disease incidence is astonishing.
We don't want to be alarmist, but we are alarmed."
The U.S. team found evidence for a variety of routes
for climate warming to adverse affect disease spread, For 【S6】______
instance, warmer winters could reduce seasonal die-off many
pathogens and their carders, or allow them to move into areas
what were previously too cold.
The researchers examined a number of human diseases 【S7】______
which spread researchers have connected to warming, including 【S8】______
malaria, Lyme disease, yellow fever and others. Most involved
in the expanded range of carriers into higher latitudes. The 【S9】______
authors concede that such connections are controversial because
countless factors except climate, such as economics and failed 【S10】______
Prevention measures, play roles in the spread of human diseases.
