two billion people lack access to essential lifesaving supplies, such as blood and vaccines
(疫苗). In the African nation of Rwanda, for
example, several remote health clinics do not
have sufficient quantities of blood and other
healthcare products. A company called Zipline
is trying to address this problem. It uses drones
(无人机) to transport medical supplies around
Rwanda. A drone can now deliver medicine in
30 minutes.
Drones are also assisting emergency
organisations after natural disasters. In 2015,
for example, a powerful hurricane destroyed
thousands of buildings in the Pacific island
nation of Vanuatu. Around 75,000 people lost
their homes, and at least 15 died. After the
storm, drones photographed the damage. These
surveys helped emergency workers assess the
situation quickly and answer important
questions: Which areas were hardest hit? Were
crops damaged? What roads were affected?
Drones are also helping to protect wildlife
populations in parts of Africa and Asia. Every
year, poachers ( 偷 猎 者) kill thousands of
elephants, rhinos, and other endangered
animals. To stop them, the environmental
organisation World Wildlife Fund is using
drones to find where poachers are hiding and if
they are carrying weapons. Equipped with
infrared video cameras, drones can easily
identify people and animals at night. These
drones are not only helpful, they are affordable.
As well as finding poachers, drones can
be used to track animals. Scientists at Liverpool
John Moores University(LJMU) plan to employ
drones for an ambitious conservation project:
documenting the world?s wildlife. The longterm project will start with scientific surveys of
animal populations. And animal species can
then be identified using special software.
Ironically(讽刺地), a tool originally
created for military use is increasingly being
used to save lives instead of taking then.
Drones have the potential to provide solutions
that will benefit both humans and animals.

My elephant adventures began in 1984
when, with our one-year-old daughter, my
husband and I crossed the jungle in a jeep,
sticking behind a lorry for comfort and company.
The elephants standing like watchers on either
side of the forest highway had us praying for
our safety. One elephant made loud noise and
angrily pawed ( 抓) the ground, warning us
off. We raced away before they could attack.
It was wise to keep elephants at a distance.
We heard stories of tourists whose jeeps were
overturned, and a couple of photographers were
