Why we need to be sustainable (Argument Writing)

Does the world need to be sustainable? Is the Pope a Catholic? In a word, yes, definitely or absolutely would be appropriate. Sustainability is a vital part of this world’s survival, and if the trees keep getting cut down, pollution being pumped into the atmosphere, and natural resources exploited, then there won’t be any earth left to live on. Research shows that there could have once been rivers and water masses on Mars, or even life forms. Now it is known for being a big red desert that couldn’t sustain a life form. No-one knows what happened on Mars, but I hope that the same doesn’t happen to Earth because of Global Warming.
One of the primary reasons to be sustainable is the trees; if we humans keep cutting the trees down to create paper, because it is all being wasted, then the Carbon Dioxide (CO2) levels in the air are going to keep rising. Trees absorb Carbon Dioxide (CO2) and then release Oxygen (O2) back into the atmosphere. This (at least partly) counters the emissions produced by humans, factories, cars, etc, and with the number of all these rising, we need trees more than ever. So why is it that trees are getting chopped down right when we need them the most? It is because of people who think that Global Warming will never affect them, and are not recycling their paper waste.
Another great reason for being sustainable is that if we keep polluting, then disastrous things will happen to the environment. Already, Average temperatures in Alaska, western Canada, and eastern Russia have risen at twice the global average, according to a called the “Arctic Climate Impact Assessment”. Air pollution can cause very bad things to happen; aerosol sprays such as hair spray (or chlorofluorocarbons) can cause the Ozone layer to thin and get holes in it, this will increase the chances of us getting skin cancer (or melanoma) from being in the sun. For more about air pollution, see THIS SITE. Also, Greenhouse Gases will trap all the Sun’s heat on Earth, and cause the polar ice caps to melt and the world to become unbearably hot. To understand this better, follow THIS LINK. Greenhouse Gases are caused by burning natural resources, and that brings me into my last point.
The Earth’s natural resources take thousands (or even millions) of years to form, and us humans have evolved and come along and dug the Oil, Petrol, Diesel, Coal, and more up and just burned it like there’s no tomorrow (which, of course, there won’t be if we keep polluting the way we are). If we keep doing this, the fumes from the burning are going to pollute the atmosphere, and in turn, cause Global Warming. Secondly, those same fumes are going to cause major health issues for those who are stuck near, or working with, the fumes. And thirdly, if we keep burning the Earth's fossil fuels, then aside from ruining the environment, creating health hazards, and causing Global Warming*, burning them means that there will be no petrol, diesel, LPG, coal, or any of the other fossil fuels left for the next generation, and the generation after them. So I think that everyone should experience stuff, and the people of the future are going to miss out on this if we don't stop soon.
Likely side-effects of the Global Warming include melting of sea-ice (the Arctic especially affected), expansion of deserts, rainforests and forests growing smaller, increases in the intensity and regularity of extreme weather events such as tornadoes and flash floods, more species of animals going extinct, and many more. As I have mentioned, if we are not sustainable we will cut down all the trees and pay for it with our Oxygen, Global Warming and it’s by-products will destroy the environment, and the burning of natural resources will also cause major grief for the entire planet’s eco-system. So for all these reasons and also many more, we should be as sustainable as we can, else the past of our planet be in vain, the present a waste of time, and the future almost non-existent. There are simple ways to change, such as recycling and reusing paper and plastic, but also more scientific ways, such as Mitigation (the reduction of greenhouse gas release, though it would take centuries to work effectively), Adaptation (which involves various measures that range from installation of air-conditioning to abandoning cities and towns threatened by sea rise), and finally Geoengineering (pretty much just changing the Earth’s natural environment to suit us, like removing carbon and carbon dioxide from our atmosphere).

You write very well. This is in fact better than some of what Sasha has to mark at university. What you need to do to improve is to reference all your 'facts' - that means put in brackets after your statements about Mars, etc, the name of the book or a link to a website where you got the info. There are very specific ways to do this and it varies from place to place [which is annoying], but you have been introduced to APA style referencing in class.
Keep up the good work - yours is a magnificent sustainability blog! Well done :-)
... And should I bother re-typing any of it into Google?
And yes, the Pope is a Catholic. Was he also in the Hitler Youth movement once upon a time? And does that mean he's 'bad'?
