Hi, Mr.Chasse

wouldn't we save a lot of trees by shifting wood products to recycled wood and artificial wood?
Shouldn't Co2 promote growth in plants?
How does wood ooze(I think it's sap)
Is it possible to ban coal so that our global warming problem might shrink considerably?
Doesn't the debris in your rain gauge affect your data?
Hey Scott, thanks for writing. I'm sitting here with Mr. Lewandowski right now--he's my roommate. You have a good idea..we should be reusing wood. There's a lot of it that is scrapped. If it's used as fuel it will release carbon into the air but as long as we're keeping our forests healthy and replanting native trees where they should be, we can keep the cycle in balance. CO2 does stimulate plant growth..in fact, they need it to survive. The problem is there aren't enough plants to take in all the carbon dioxide from our atmosphere. We're overloading the atmosphere with it and, at the same time, we've been deforesting the earth. This throws off the balance. Burning coal and oil releases even more carbon into the air, adding to the CO2 humans exhale, the CO2 released by electrical energy and the CO2 released by decomposing plants.
Politicians, environmentalists, scientists and the energy industry are arguing about coal right now. Many countries are building coal fire plants thinking that if they get them built before laws pass, they will be free from those laws. There's a lot of coal in the earth but if we use it, it will only increase global warming.
When I say that wood 'oozes' I'm being a little bit poetic. But if you think about it, in the course of tree time --dendrochronological time--wood really does behave a lot like liquid in its growth and the way it adapts to situations. In a way, it looks to me as if wood 'flows' like a liquid with high viscosity (honey, for instance). Have you ever seen a tree whose wood has grown around a fencepost or street sign?
And yes, you're right about the debris in the rain gauge--it will displace the water throw off the measurement. I removed the leaf before measuring. Even doing that, I realize that some water gets removed with the leaf. That's why there are many rain gauges in a field (20) so an average rainfall measurement may be taken.
Best wishes, Mr. Chasse.
Hello Mr.Chasse I am Alex Luu form aiea high school, a student of Mr.Lewandowski
I was looking at the pictures that you had and I saw some intresting stuff.
Do you have any ideas on how to reduce global warming such as a new invention or something like that?
I hope you enjoy your time in the forest.
hi mr. Chasse. I'm one of Mr. Lewandowski's students from his Period 1 (Chemistry). Do you mind if i ask a question?
Do you think that the data you guys are gathering are going to influene future earthwatch projects such as this? And do you think this project is going to help educate more people about climate change? :-D
