When I actually calculated what the land and sea areas of the Earth have been and might be in the future and when I considered the amount of time it takes for the sea level to change (even with our current high usage of energy and fossil fuels), I had a better perspective on the issue. It is a far more serious matter that, for example, in my lifetime the population of the Earth has more than doubled and a large fraction of the population has living standards that would generally be considered unacceptable.
My keynote address (there were several keynote addresses on each day of the conference) at the 3rd International Conference on Sustainable Energy & Environmental Protection was well received on Friday 15th August. I was delighted to have a truly international audience that included some very highly respected experts in the field. On the previous day there had been a round table discussion in which I participated and that too had been a very stimulating experience for me. None of us have all the answers to the challenges we face in the area of sustainability.
Using-up non-renewable energy resources is an issue, but using-up chemical elements that exist in concentrated form and dispersing them minutely within the environment is, at least, as important an issue.
I believe it is important to allow and encourage debate about all the options that are available to humankind. Globally concerted action, respecting and involving all stakeholders, is required to address the challenges.
My slide presentation is available in the Dublin Institute of Technology’s ARROW archive at the web page link below. The file size is 41 MB because it contains a total of about 43 minutes of audio for the 62 slides, so it may be slow to download in a browser window (6 minutes with my home broadband connection). In due course I hope to have a paper based on the presentation published in a journal.
