Hi, I'm
Alexandra, and I'm an astronaut. I am working on a space station that
has instruments to measure the air pollution on Earth. We can also see
where the ozone layer is thin and what the effects of global warming
are.
The air here, in Beijing, is often dirty. But we must make it clear
by next year for the Olympics.

Hi, I'm
Alexandra, and I'm an astronaut. I am working at a space station that
is orbiting around our beautiful planet, the Earth.I often marvel at
the Earth, I think a lot about its future. Have you ever seen pictures
of our "blue planet?" You know, it's called blue because three
quarters of its surface is covered with water. Even the white ice caps
on its poles are water. And it has some water under its surface. But
from all this water the creatures on Earth can only drink 1 percent!
And all creatures need water!
How
long do you think we'll have clean water to drink?
Hi, I'm
Alexandra, and I'm an astronaut. I am working at a space station that
is orbiting around our beautiful planet, the Earth.I often marvel at
the Earth, I think a lot about its future, and I'm afraid that one day
it is going to end up like a huge trashdump.
Where
does your trash go?
What does hazardous waste do to our planet?
Hazardous waste can kill plants and animals. It has
already harmed the ocean life when oil spilled out of
ocean liners. [Rex04 - Germany]

What
if all the energy sources of the Earth will be get used up?
Will everything stop working and go dark?
Where is your energy coming from?
We'll never use up all the energy sources. People are working on
coming up with new ways to make energy. For example, if there is not
enough oil, cars can run on electric power. [Jason-USA]

Do
you know how our planet connects to other planets?
What is our place in the universe?
Are we alone here?
