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.
