Now I am confused

By -
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.

If we don't pay attention to the warnings and take action now, it will mean the end of our survival as a species.

According to a colleague of mine, the depletion of the ozone layer has been captured with the control of the ozone depleting chemicals. I wonder if this is really true or are we facing many different threats (most of which are self incurred).

Both global warming and ozone layer depletions are two different issues,, eventhough both are the signs of the sufferings of our mother nature. Dont get confused,,coz these are the major threat to mankind today compared to anything else. Your friend may be right about the control of the ODC(Ozone depleting Chemicals) but who is controlling them? CFC, CF4 and halons (which contains bromine instead of chlorines) are still found in most of the products. And the countries that is taking these control measures are those who has terrible ozone condition(Im not even sure if they are serious about it due to its high cost in order to find a substitute for these chemicals) This clearly shows that the countries without razor thin ozone layers dont care much about these ODC,,(which is depleting their ozone gradually). And there will be a hole soon,, only then they will take this seriously. We cant count on the authorities, the survival of homo sapiens comes from the very individual of us,, stop using aerosol sprays,, air conditioners,hair spray,, (phh! B,, is this possible?) talk to my sisters about hairsprays,,and can you drive around your car with the windows unwind? If we cant do it as an individual,, no point worrying,, coz we asked for it,,.

Removing Skin Tags

I do not remember when I skin tag first appeared on my neck. Skin tags may appear cosmetic, but I have some tags that feel sore, the kind of soreness that seem to come from the nerves. At first, I did not know what to do with the tags, but luckily for me, my wife came up with a way to remove the tags. She pulled a strand of her hair and tied the tag. The tag will turn black and fall off together with the hair. This approach was effective until my wife decided to shorten her hair and her eyesight started to deteriorate. Since then I tried looking for alternative ways of removing the skin tags. One of the approaches is to apply apple vinegar on the tags. I tried it, but it did not work for me, either because of the way I applied or because I had not applied it frequently enough (I applied it only at night because of the strong smell of the vinegar). I considered freezing the tag using hydrogen peroxide - treatment used to remove benign warts. The pharmacist recommended an alt...

Anime Review: Rakshasa Street

I recently watch this anime that was in Mandarin with English subtitle. The story revolves between a girl and two brothers. She met him while crossing the road without looking. He knocked her down and caused him to lose the food he was delivering. This chance encounter explains why she calls him and why he calls her stupid girl. The anime consist of 24 episodes. The development was good, the first episode focus on her looking for a job as a fresh graduate at a job fair (where thousand of others are doing the same thing). Later she receives a text to attend an interview at night. While walking towards the interview, she looked around and realized that the building looked spooky. She then started thinking of why a company would call her for an interview so late in the night - human traffickers or organ traders. By then she was lost in Rakshasa Street filled with demon soldiers. Turns out that she is in a place for the dead and humans are forbidden there. I enjoyed the story....

Movie Review: Zootopia

By -
Initially I was not interested in watching Zootopia in the cinema, but my son expressed interest in the movie. However, he was too busy with a lot of other activities and was unable to go with us. Instead I took my daughter with me to the movie. We loved it, the storytelling was great, it has mystery, plot twist and humor. We are first introduced to Judy Hopps, a bunny who wanted to the first rabbit to join the police force, but both her parents did not support the idea. They preferred that she continued the family tradition and remain a carrot farmer. Most would have succumbed to the pressure and give up the dream but not Judy. Her partner is Nick Wilde a fox; Judy fell for one of his scams during their first encounter, but managed to blackmail him to help her later in the movie. The movie makes good use of stereotypes in the story, showing how societies prejudice pressures makes some of these stereotypes, self fulfilling (as in the case of Nick). Judy and Nick reminds me of 48 h...
