Of recent times we have seen a hysterical level of denial of climate change science reminiscent of the kind of madness that prevailed around the issue of whether the earth was flat during the middle ages and more recently, whether the earth was the centre of the universe, as it was "written", during the time of Galileo.

The passion and anger... even hate that surrounds this issue can only be explained by irrational fear. Fear of change is what drives most emotional debates and this is underpinned by fear of mortality.

Change is a fact of the universe. Nothing stays the same. We can choose to put our head in the sand and pretend that everything will always be in our comfort zone and never change and that we will live forever and the tooth fairy will come and leave us a gold coin and that.... shouldI go on?

Change happens. It is happening all the time. We can choose to ignore it and suffer the consequences or we can embrace change, do our best to control it and make it work to our advantage.

So it is with climate change. Instead of making threats to our scientists, as some angry loonies, stirred up by Tony Abbott's hate politics have been doing, we should be looking for opportunities to benefit from the changes that are attached to the need to protect our environment.

Take the example set by Denmark. Tiny Denmark with very little land and a smaller population than Australia has made the wind turbine industry its own. Every time a new wind turbine is erected somewhere in the world (and one is put up each hour in China alone), the cash registers ring in Copenhagen.

Denmark is laughing all the way to the bank.

Australia has massive tracts of empty land, ideal for harvesting sunlight. We have a coastline that is longer than just about any country in the world where wave energy can be harvested. A study has found that there is enough accessible wave energy around our coastline, where most of the population lives, to provide 3.5 times our electricity needs. And it is BASE LOAD energy.

In pursuit of my passion for the commercial opportunities offered by the need to develop sustainable and renewable technologies, I have built a website which is a guide to investing in public companies in Australia that are working on these technologies. http://www.sustainable-renewable-guide.com.au/ is my answer to the naysayers and the low achievers who simply have nothing to contribute other than criticism.

Even if the greenhouse effect was not a threat to the environment, there is a very strong argument in favour of environmentally friendly technology. Pollution cost billions of $$ per year in health impacts on our society. And then there is the issue of peak oil. (Another issue that the deniers have latched onto, firmly planting their heads in the sand in their irrational fear of change.)

Opportunity knocks but once. You can either jump aboard the freight train of opportunity or get run over by it. Check out the website and dare to be part of the solution.
