Snorkeling underwater photos in green water

These photos are from a week or so ago when we were in Nha Trang, Vietnam. I have delayed in posting these photos because they just didn't look that great due to the green water making all the photos green.I then put the images into GIMP 2.0 (open source image manipulation programme) and experimented with changing the colours to compensate for the green water. I tried a few different things but in the end the simplest best way to improve the images was to use the curves tool, selected the green channel and lower the line with a simple adjustment. Then a few more tweeks with saturation and contrast lead me to be happy with the images. Please tell me what you think.

Isaac Asimov previendo el impacto de Internet - YouTube

How amazing that Asimov predicted so many of the things we are seeing today over 20 years ago. I think Isaac Asimov is the perfect example of how Sci Fi writers (either books, TV shows, movies and more) are some of the best guides to what will happen in the future, If you rewatch the 2001 space odyssey film you will A) improve your life and B) see an iPad decades before we get it in our hands. Sci Fi does a great job at both predicting and i think shaping the future! Sadly a large part of this video is dedicated to one potential benefit of the internet that Asimov is excited about but we have still not seen. The education system has still not been shaken up and we are not letting people learn in a natural discovery way or with reference to their own passions. Asimov is talking about a wide scale education overhaul which is made possible by the internet and technology. I hope that this will come true!

Fishkeeping in a Cambodian Rice Field

Improving subsistence farmers diet with fish husbandry in Cambodia How can a bunch of fish ponds make a real difference? This summer I am travelling around South-East Asia, including Cambodia. In Cambodia I will be visiting some NGOs and voluntary aid projects . I meet with our main contact this week and most of the work is focused on people projects, teaching English, prison visits , drug addiction etc but they mentioned one project where they help rice farmers start fish husbandry projects. These projects are designed to help the local subsistence farmers grow on fish to adult size for increasing the protein component of their diet. Being interested in all forms of fish keeping I hope that when we travel to Cambodia I can visit the project or at least meet up with the team managing the project. It sounds like a fascinating and practical way to help some of the worlds poorest improve th...

Another way to damage the marine world

Reading this article I am struck by how easily marine impacts are being ignored. Even within developments that relate to the marine world and explicitly use the sea as a selling point whilst slowly bringing about it's death. I know that the Arab gulf is not the only place in the world where marine ecosystems are being ruined by development but the rapid development of the mega structures on the coast could have so many unpredictable results. Historically it seems that humans have always found it easy to ignore damage in the sea, from dumping waste to the rise of the whaling trade we just love to cause destruction. I believe we find it so easy because we simple have the attitude of out of sight out of mind. When we cut down the rainforests it is easy to see, when we create massive landfill sites we see it when we create concrete jungles clogged with pollution we see it. But the waves cover the marine world so that most of us never notice the grow...
