The
UN Environment Programme says that rising temperatures could mean the end for
some migrating (迁徙) animals.
Migrating
animals move through several environments as they travel away from the cold
areas in winter to warmer ones. Birds may fly from one part of the world to
another, perhaps stopping at feeding grounds on the way. Whales and turtles
travel through huge areas of ocean. A report says that changes in any one of
the places where these animals stay can cause serious problems. "Obviously
these animals have developed their travelling ways over thousands of years. But
weather change is much greater over the next 25 to 50 years and it is
impossible for these animals to change their habits fast enough," said the
report writer Dr. Robert Hepworth.
Turtles
are hit hardest by rising temperatures. Scientists have found that at higher
temperatures, turtles have far more female(雌性) eggs
than male ones. In parts of Malaysia, turtles are only giving birth to female
babies. And some turtles are more probable(可能的) to
develop cancer as the waters get warmer.
With
birds, the main problem is the harm to important areas at the end of their travels
or at resting places along the way. About one-fifth of migrating birds are now
in danger because of these changes including rising sea levels, land loss and
more strong storms.
Some
other animals are now in great danger. For example, the North Atlantic Right
Whale (北大西洋露脊鲸)is losing their food because of the changing ocean flows(流动); the White-Nose Dolphin is out-competed (淘汰) by other kinds in warmer waters.
The
report is not all bad news. Even with the temperature changing, protecting the
environment can still help migrating animals return. "We need governments
to start taking action all over the world. The clock is ticking. We
should make full use of every minute." said Dr Hepworth. And now some
projects are already working! Whales are changing their feeding habits, finding
new feeding grounds and new foods to eat.
