1.What are a couple of examples of how animals have
changed because of climate change?
2. What is some
evidence that proves that climate change is
3. Can people die because of too much
carbon in the atmosphere?
4. Where is climate change
effecting in the world the most?
In your opinion,
can climate change be stopped?
5. What year is

We are in an
investigation project for school and are trying to
get these questions answered by Tuesday, May 31.
If you are able to answer them, we would REALLY
appreciate it and were wondering if we could also
add a picture of you as our expert that we asked
questions from. If that is fine, can you also
send a picture with your answers. We are using
our teachers email because we do not have one.
Thank you sooooo much.

|201: ||I seem to recall reading somewhere that crystal
clear sea water was not actually a good indicator
of a healthy environment from a wildlife
perspective. My understanding is that crystal
clear water is that way because it contains no
sediment/nutrients (which make the water cloudy)
and therefore, nothing for microbial life to
consume. This in turn feeds up the food chain
meaning that, while clear water appears ideal from
a human perspective, the reverse is actually true
and that it is bad from an ecological point of view?
Can you confirm this?

|248: ||Hello! I am doing a school project on trees. I saw
your article on the question
"How come plants produce oxygen even though they need
oxygen for respiration?" I have a similar
question. I am wondering if
there is a way to make trees produce more oxygen.
I know that they
produce oxygen during their photosynthesis by
using carbon dioxide,
water, and sunlight but I wonder if there is any
way to make them
produce more by giving them large amounts of those
things. Thank you
for your consideration of my question. |

|269: ||My question to you is, can there ever be a man
made substitute for water that give us the same
benefits of water? I thought of this question
because I once heard that if water did not have
exactly what it has right now, we would not be
able to rely on it and we would not be able to
live. I wanted to know if that was true and if we
could use an alternative for every single molecule
that water has. In my opinion, it would be awesome
if people that did not have access to fresh water
could have another option to gain the nutrients
and hydration that water provides |
