Alright, I’m sure not everyone is going to agree with me about this point but I’d like to make my opinion clear on this whole "Green, Save the Planet" chant that has been attached to our generation.
I’d like to preface everything by saying that I do think making cars with better fuel efficiency is a good thing and recycling your plastics and such a great way to reduce waste and allow us to make better use of our resources. I just have a problem with the lobbyists and people behind this green movement phrasing the reason why we should do these things is because we have to save the planet. I would like to point out that this planet does not need saving. To illustrate my point, let me make a list of the events this planet has already survived:
Earth: Tougher than you Think
1. Birth - The Earth was formed about 4.5 billion years ago from the nebula (nebulan?) disk of which the other planets and sun formed. First the Earth was molten and very very very hot. And was bombarded with meteors and meteorites day after day after day for about 2.5 billion years. There was very little atmosphere on the planet so there was nothing to protect the Earth from the meteorites. Earth was a very tough place to live back then. But you know, nothing lived back then
2. The Moon - a theory suggests that the Earth was hit with a large mass (probably the size of Mars) and thus this probably resulted in the Earth being knocked around and then ejected a certain amount of monlten mass into space - forming the moon in the process. I’m sure this wasn’t a rosey day for the Earth but still it survived.
3. Oxygen - Water on this planet probably came from ice comets or other proto-planets that contained ice and such in the young solar system. The mixture of the atmosphere at this time was mostly water vapor (also from volcanoes), nitrogen, ammonia and other trace gases. But it wasn’t until, somehow, life appeared that the Earth was really plagued. Early organisms were able to use the nitrogen and ammonia for respiration (something very few organisms can do today). But as evolution moved onward, there arose organisms that were able to transform carbon dioxide (and I suppose ammonia as well) into pure oxygen. But you’re saying to yourself, "I thought oxygen was a good thing?" Oxygen is good for us and the animals that live now on Earth but oxygen is actually a toxic gas. It killed off most of the earlier organisms on the young planet.
Fun Fact: The U.S. Constitution is actually locked up in a glass case filled with inert Argon gas since oxygen has been proven to react with the paper and ink to cause decay/degredation.
You know how red Mars looks? Do you know why? Mars is rusted. Iron oxides as far as the eye can see. Oxygen isn’t free anymore, its locked up in a molecular bond with Iron on Mars until someone decides to mine it, of course.
4. Plants and water -
Plants are able to dig right into the Earth, much like water, and slowly pry the rocks apart and eventually topple mountains. These fources change the surface of the Earth over many many years. But, hey its for a good cause - this creates soil and junk, right?
5. Extinctions - Let’s talk about animals. There have been many many mass extinctions on this planet. It’s not just the one 65 million years ago that killed the dinosaurs. I believe that one was actually not that bad. These are the Big Five mass extinctions:
a. Ordovician extinction - 450-440 million years ago. Second biggest marine extinction to be studied. Probably caused by the continental plates shifting and causing temperature changes and such.
b. Late Devonian extinction - 364 million years ago. The cause isn’t really known. We do know that the two major continents before Pangea (Euramerica and Gondwana) were racing towards each other to form Pangea, this might cause some mineral imbalances in the sea as well as ocean anoxia. Another theory includes a comet. Mostly affected marine life.
c. End Permian - 251.4 million years ago. Earth’s most severe extinction, wiping away 96% of marine life (they don’t get a break, do they?), 70% of land vertebrates, and the only extinction to affect insects! This translates to 57% of animal families and 83% of all genera killed. And it also came in pulses so it must have felt that it kept going and going. Possible causes include increased volcano activity, continental shift, ocean anoxia, and some more comets or asteroids.
d. Triassic - Jurassic extinction - 199.6 million years ago. This extinction basically allowed dinosaurs to be the dominant lifeform on Earth since a bunch more marine life and amphibians and some other reptiles were killed off. Possible causes come from the usual gradual climate shift, space impacts or increased volcano activity.
e. End Cretaceous - 65 million years ago. This is the extinction that allowed mammals to be the dominat lifeform on the planet since it killed off the dinosaurs, all of them. The cause is generally accepted to be an impact from some rock from outer space.
But look at life now. It surely has rebounded, huh?
Oh, I forget, there’s one going on right now. It’s called the Holocene extinction. This is the count of species being killed off from the start of human history (probably because of human activity - not volcanoes or asteroids).
6. Lastly, the Earth is going to be swallowed by the sun when the sun becomes a red giant after a few billion years. By then, I’m sure there’s going to be tens more mass extinctions and the continents are going to shift some more (and so the face of this planet isn’t going to be familar at all).
Okay, so my point is - the Earth is one tough piece of rock. It’s not going anywhere. If a thousand asteroids could hit it and billions upon billions of animals dying on it hadn’t totally devasted this planet, I don’t think we will. My gripe is that although this green movement is totally appropriate for humans, it’s not really appropriate for the planet.
Yes, I know that the trash we produce is going to remain on this planet for thousands of years (some even millions?) but when time is measured not in single years but in millions of years, it really doesn’t matter.
This green movement should say something like, "Recyle and help save the human species". If we don’t recycle, if we don’t find an alternative fuel, if we don’t change our ways we will change this planet so much that it won’t be inhabitable for humans and a bunch of other animals. But the fun thing about biology is that other animals will evolve and adapt. So what if the humans die off? Some other animal, after million of years, will become the dominant lifeform on this planet and they’ll see our buildings and trash (if its still here) and say "Boy, I sure hope we don’t end up like that."
Let’s not be dreamers, let’s call this movement what it really is. This planet does not need saving - Humans need saving. We are an endager species to our own destructive actions. When humans disappear, the Earth will still orbit the sun and the moon will still be there hanging in the sky and I’m sure someone using some sort of eye-like organ will gaze upon it one day in the future and hopefully they won’t be as destructive as us.
