Title: A Visitor or a Host
Where do you live? Where are you living? Where will you be after tomorrow? (Showing up with projector 1-2) This is the place all of us living in. No matter who are you; rich or poor, intelligent or dumb, white or black, African or Asian, Norwegian or Indonesian, even speak English or not. We are living together in this big house.
Our living place, Earth, is it beautiful? Do you like to live here? What role would you like to play, a visitor or a host? A visitor means that you just come to enjoy, to pleasure, to consume and then go away.
A host also means that to enjoy, to pleasure, but plays more as a provider, cater, giver and investor. The visitor just concern and take pleasure in what he wants right now, no more about the next time or tomorrow, but the host shall take care of his big house and think about the day after tomorrow.
In this 5 hundred million olds planet something is going to change. Do you know what is it the most severe circumstance? I know most of you already have the idea, global warming. Yes it is. Some of Toastmasters fellows had shown up similar topics on their speech in our club before. I’m sure most of you have the basic knowledge connected with this topic. But I would like to remind you again what severe situation we are facing now and offer more evidence and go into a little more detail about it.
---What we did yesterday and doing right now continuously hurt it— All we know that the earth is protected by the atmospheric surface.
Earth's atmosphere is a layer of
gases surrounding the planet and retained by the Earth's
gravity. (Showing up with projector 3-4)
There are 4 layers to protect the earth. Ozone layer (the most famous one and almost every one knows it)--It is vitally important to life because it absorbs the harmful ultraviolet (UV) from the Sun. Ozone layer is going thin and disappear---main cause of Global warming.
It has been claimed that the Earth's climate warming is due to the changes in the relative concentration of gases in the atmosphere. The gases involved are: (Showing up with projector 5)
Global Warming is caused by many things. The causes are split up into two groups, man-made or natural causes.
Natural Causes-- One natural cause is a release of methane gas from arctic tundra and wetlands and animal metabolism.
Man-made Causes-- Man-made causes probably do the most damage. Pollution is one of the biggest man-made problems.
Reasons –Pollution (Pollution is the introduction of pollutants (chemical substances, noise, heat, light, energy, etc.) into the environment which resulted in deleterious effects of such a nature as to endanger human health, harm living resources and ecosystems.)--- increased carbon dioxide (CO 2)
(Showing up with projector 6-11)
Temperatures going up cause the effects of Global Warming---
(Showing up with projector-12-14)
Global Warming – Cause the Green house effect-- Cause the Climate change -- Cause the agricultural problems-- Cause the economics problems -- Cause the political problems –Then what ???
The most severe circumstance is effecting on ecosystems and human health.
So far right now, if you followed my ideas you may waiting my suggestion or advice for what should we do or what we shouldn’t. No, I’m not going to offer or suggesting any bearings on them. I’m just demonstrating the severe situation we are facing now. And evoke you to think about what role we are playing in and that would be the tomorrow, a visitor or a host?
