Showing posts with the label Global Warming

Now I am confused

So what is the greatest threat that mankind is facing. I guess I have lost touch. All this while, I still think that the depletion of the ozone layer is the threat because, by depleting the ozone layer we allow all the harmful rays of the sun to enter our atmosphere thus causing cancer or other skin diseases. However, as I watch the show - Al Gore's "An Inconvenient Truth" , it talks about global warming. Apparently global warming is different from the ozone depletion. The global warming is actually the rays of the sun that are deflecting from earth is not able to escape the atmosphere. For those who have not watched the show, I encourage you to watch it. The message it is trying to convey is critical to our survival as a species. According to the show, the recent disasters which we are facing in recent years can be linked to the global warming - primarily diseases like SARS and recent disasters like Kathrina and recent earthquake.

Saving the environment with alternative fuel?

With the recent increase of oil prices, there is new incentive for searching for alternative fuel. Let us review what are the current alternatives: Nuclear energy. Hydro energy Coal Wind BioDiesel Solar Energy. Nuclear Energy When Nuclear energy was first proposed, it seems like it is the answer to all the power but as you know now those who are using them have to find ways of disposing all the radio active waste generated. True the generators generate immense energy but the waste is very toxic to the environment. Hydro Energy Hydro energy is great for countries that are blessed with hills and waterfall. However, the process of building the dam and the reservoir for this requires that we clear out vast forest and eliminate natural habitats of animals there. The other problem has to do with the sludge that will accumulate over the years when the hydro electric plant operates which if not handled properly will cause the plant to be unusable. Overall though this is still one which caus
