UMTMOOC – Large Scale Ecology : Global Ecology


Assalamulaikumwarahmatullah wbk and one greetings from Terengganu First of all congratulations for having made it to the very last module and the Large Scale Ecology section the very last topic of this course You have surely noticed that as you progress in the course from one topic to another you have in a way been gradually upscaling From understanding the importance of invisible atoms in energy and nutrient relations to microbes in food chains then to the interactions within and between species as well as how they fit into their respective ecosystem You will now after looking at ecology from landscape and geographic perspectives discover the exciting realm of Global Ecology This course will firstly introduced you to the Earth’s atmospheric envelope Yes! that thin, fragile layer that is critical to our survival on earth and this will help you understand the greenhouse effect that our planet is currently facing and the impacts on its meta scale ecology and finally the role of human species in all this and not only as contributor to global ecological problems but also as part of the solution Let’s begin by getting to know our precious atmospheric envelope from its fluffy clouds that we see to the invisible gases that it is made of as well as the importance to life on earth What better way to do that than by listening and singing to Mr Parr’s phenomenal atmospheric songs! let’s do it This layer has all the cloud Troposphere life will be found sun warms the ocean and ground I’ll tell you Breathable gases in Here warm sun radiates this layer gets cold as you move Up above as it turns to the next layer The atmosphere is why there’s life because the raging sons of firing Sky fans to the Ozone Rays are affordable of the sun Stratosphere here we come planes fly there to and fro the ozone layer is among It’s got ozone really so neat Blocking some rays like UV it rises up like a tide the temperature it will rise The atmosphere is why there’s life because the raging Sun’s a fire in the sky Thanks to the ozone rays are absorbed of the Sun Mesosphere is cold Meteors will glow, molten And all your for fears will subside All the meteors will fry Ionosphere’s on the list Aurora Borealis And the exosphere will disperse The hottest layer of course The atmosphere is why there’s life Because the raging sun’s a fire in the sky Thanks to the ozone Rays are absorbed of the sun Thanks to the ozone Rays are absorbed of the sun Yes, Rays are absorbed of the sun Now we all live in the troposphere with drops of water and breathale air, hey It has all the weather like snow and rain This layer is heated from below, hey Sunlight warms the oceans and the ground It radiates the heat all around, hey, hey Tell me, do we live in the troposphere Lowest layer of the atmosphere To see the clouds and water All life lives in this layer And tell me are you safe with the ozone layer? without it you’d have permanent scars and then you’d miss it we should be thankful for the Stratosphere Now Stratosphere is the next location The ozone layer helps civilization, hey The temperatures climb as one will rise And jet aircraft, well they will fly, hey Now the next one is the Mesosphere I’m afraid that this one is the coldest layer Most meteoroids from scape will burn And they will us without any concern But tell mee, does the mesosphere have shooting stars Did you ever get the chance To see them in the light of day Coldest layer by the Milky Way And tell me, does the Thermosphere blow your mind Ionosphere, Exosphere combined The hottest layer And it dissipates to space out there Thermosphere has the Ionosphere, Exosphere Aurora Borealis, UV radiation Both are in the Ionosphere and then there’s the hottest, highest layer Earth’s atmosphere becomes thin The exosphere is where the molecules mix with space Tell me, do you live in the Troposphere Did you finally get the chance To see all the storm clouds today That means it might rain all day But tell me, are you safe with the ozone layer Convection currents heat the earth that way To cycle the heat in cycles The Strosphere isn’t overrated And tell me, does the Mesosphere have shooting stars It’s the coldest layer by far And then you see them While you’re looking for meteors Na, na, na, na, na, na Na, na, na, na, na, na And did you finally get to see The thermosphere has two layers Na, na, na, na, na, na Na, na, na, na, na, na And this is the hottest layer This is the hottest layer Na, na, na, na, na, na Na, na, na, na, na, na And then it dissipates into space out there….. Now my fellow atmospheric “rock stars” to not agree that we are a blessed bunch thanks to the atmospheric envelope that reflects back 30% of the solar energy back to space leaving just enough to make things work for us on Earth but how you ask well through the Greenhouse effect, of course? You’re not sure what that means? well, watch the short video by Nasa Earth Observatory that is linked to the image of the slide to find out Now is that not amazing? But as you have seen the Global Energy Equilibrium meaning the amount of energy released out and trapped within the atmosphere which depends on the greenhouse gases needs to be maintained to ensure that our planet stays healthy This is because our global system such as the El Nino and La Nina phenomena which are the main players in the El Nino Southern oscillation or enso are affected by it And destructions of these global systems will impact life on earth As proven by scientists studying the impact of climate change on various animal populations The population of mammals in the arid deserts of Australia for example will boom or bust depending on the faces of Enso And ever wondered what role real human beings have in all this our activities on earth through intensive agriculture and industrial processes that cause fossil fuel burning and forestration may have in effect and it back to the global ecological systems I learned the answer to this question when i was a teenager Thanks to a movie So, i thought i should share it with you which is definitely more fun than listening to leave for an hour So please watch the movie to the link provided on the slide To find out whether we are part of the problem or the solution So what have you learned from the movie? that Kevin Costner was once an eco-friendly bartender before he became a bodyguard or a baseball player depending on the movie you watch Oh, no.. That’s cool!! But I also hope that you learn about the negative impacts of human activities on our planet For example intensifying the greenhouse effect by increasing the amount of greenhouse gases through fossil fuel burning plus thinning the ozone layer to the use of hose and humming chemicals But most importantly i do hope this film has also given you the inspiration to positively contribute to our planet’s healing It is really not too late in fact we have already achieved some success The Montreal Protocol that was set up in 1985 to protect the ozone layer has achieved its objective In 2003, scientists were able to produce evidence that the ozone layer is recovering More and more positive outcomes have been reported since Click on the video to the BBC report to find out more about this Now aren’t you glad that you’ll use aerosol free products? Not together let’s continue to keep our planet in good ecological balance and well done You’ve completed this course and will now be able to ensure that our global ecological balance is maintained Good luck to us all and thank you
