Takayna, the book and film.

Help make this Pozible, donate today!

I have just pledged $35, because I love books and it looks like a great design! I think it’s a great way to inspire people to protect this wonderful area.

There is only one week to go on this campaign. I hope some of my connections can also contribute.

I have shared this video with my whole network! I have also pledged $35. And yet I am unemployed. So if I can do that, then so can most people.

Here is a direct link to this crowdfunding campaign: https://www.pozible.com/project/takayna-tarkine-book-film

(for some reason the hyperlink isn’t ‘active’ even though it should be, please highlight the link, copy & paste into another browser window, I have been trying for ages to fix the link with no luck so far… I have also added a link to the pozible campaign in the youtube comments section)

The problem with using biofuels in aviation.

Recently on LinkedIn:

First, it’s a premise of sustainable, alternative fuels that their production actually draws down atmospheric carbon–the carbon comes out of the atmosphere to make the fuel. The carbon is released again when the fuel is burned. By (albeit partial and imperfect so far) application of that principle, vastly lower net emissions (on the basis of life cycle analysis) are now possible.

I understand all abot life-cycle assessment. Yes, true, biofuel crops do take CO2 out of the air. 

But not if brazilian rainforest has to be cut down to make way for new plantation crops — because the native forest already does a way better job of taking CO2 out of the air than a crop with less biodiversity ever will. 

So my question is: where are we going to grow all of the new crops that will be needed for this additional biofuel?

It’s no good saying that new sustainable crops will reduce the CO2 from the air if you harvest the whole thing every year and burn it again. That only releases the same carbon that was absorbed by the crop in the first place… so no net CO2 increase. (well that is probably an over-simplification, because some carbon dioxide no doubt goes in to the soil) [Read more…]
