The Age of Stupid - Great Climate Change Documentary


Blue IcebergsToday I saw a really great climate change documentary. It was called The Age of Stupid and was directed by Franny Armstrong. It was set in the future 2055 to be exact. The premise is that the one guy is basically the last, or one of the last, human on Earth. He is reflecting on how stupid humans were to have ruined the climate and become extinct even though they clearly saw it coming and could have stopped. The great line from the movie went something like this, "Humans certainly aren't the first species to kill themselves off, but they are the first to do it when they saw it coming". He goes on to compare what happened to suicide, which really fits quite well when you think about it. 


It is basically a montage of news clips which were real, except for the ones from the future of course. One of the really interesting concepts I took away from the movie is a great way to look at the whole climate change issue. Essentially it all breaks down to how much land is needed to support the number of people in the world. This includes the land for trees to create lumber and paper, the land for stream for us to drink, etc etc etc. It all comes down to how much resources this planet has to offer and how much we are using. Clearly right now we are using more then are replenished by Earth year after year. That is working for now because this planet has so many resources, but it is quickly starting to catch up with is for two reasons.

Reason #1 what we are doing isn't sustainable


First we can't sustain what we are doing now because there are just so many of us and the number is growing. This is what it all comes down to for me. I keep going back to the fact that there are just too many of us. Like it seems no matter how basically we decide to live our lives when there are 9-10 billion of us, it just isn't going to matter. With that many people we are just going to use more then the planet can replenish every year. This means were are going to be dipping into the planet's reserves of resources every year, and at some point there just won't be any left. It's just like a financial budget. You can spend more then you make for a while, but eventually it just catches up with you. Even if you have money in the bank, if you keep dipping into it each year eventually it is going to be gone, and then it's game over.

Reason #2 what we are doing isn't sustainable


The other issue with people is the amount of energy we use every year. Not matter the form we are essentially using energy. Whether it be the food we eat, the paper we write on, the clothes we wear, the house we live in, it all consumes energy in one form or the other. It's this energy which is the resources that I'm talking about. Not only are there so many of us living our lives that we are using more energy then is created by the sun shining on the planet each year, we are also using more and more of it each year. American specifically are the worst. We have be industrialized the longest I guess so we've just gotten used to being consumers. The goal of consumerism is to keep getting people to buy more then they did last year, and it works great until you realize that the resources are finite and there is just no way around the fact that you are going to eventually run out of resources.

A really interesting fact from the movie is that if all people on the planet right now lived the way that the average American does we would actually need 5 planet Earths to sustain it all! So with the amount of people alive now, living like we do in America, we would need more land to create all those resources each year. How much more? 5 times what we have now!!! And just think with climate change speeding up the caps are going to melts and there is going to be even less usable land as time goes by. It's like a train with no breaks going down hill!

Oil Pricing And How Soon We Are Going To Run Out Of It

Oil refineryI heard a really interesting news story on the radio this morning. They were talking about oil pricing and why even though US demand is down overall the price at the pump remains high. Typically when demand goes down the price should be going down as well. For the time of year (gas is usually cheaper in the winter time) gasoline and diesel are are historically high national averages. 



Lower Demand


So it turns out that the demand for oil is down in the US because of two main factors. The first is that the economy is still bad and many folks are still unemployed. Because there are many fewer people driving back and forth to work every day we are buying less gas. Also because people have less money in their pocket because of the bad economy they are thinking twice about spending at the pump. The other main factor is that, on average, the cars on the road in the US are getting more and more fuel efficient. Pruis, Volt, and Leaf and others are major contributors to this reduced need for gas. But all newer cars in general are getting better and better gas mileage which is having a real effect on the amount of gas we are all buying.

Why is the price saying so high then?


Well it turns out that the oil refiners here in the states started to realize they were ending up with a surplus. They also realized that the emerging nations are needing more and more gas and diesel, so our refiners are actually exporting it to other nations. This is a time when the overall economy being so global is bad for us. Normally give the existing conditions and reduced demand we would see a nice drop in the price at the pump. But because US oil refiners have found a market to still be able to sell that surplus the price is staying as high as ever. Ouch.

Craziness!

So let's think about this. Oil is pumped out of the ground in the Middle East. It is them put in oil tankers and shipped across oceans to the US. US oil refiners in NJ, Louisiana, and other coastal states then refine this oil into it's elements (gasoline, diesel, etc). Most of that is then trucked in tanker trucks to the gas stations all over the US for us to buy. But increasingly some of that gasoline and diesel is being put back into oil tankers and shipped back over oceans to developing countries where demand for oil products is increasing rapidly. The inefficiency of that whole process just boggles my mind!! The energy that it takes to create oil which we use to create energy is staggering!

When are we going to run out?


So just in case you never thought about it before, oil is a finite resource. That means there is an exact amount of it underground on Earth and no more. Once it's gone it's gone. It's been so plentiful for so many years that for a long time nobody put any thought into running out of it. But it is indeed going to happen and really is all ready happening.

The key really isn't so much when we suck the last drop out of the ground, because we are never as a planet ever going to see the last drop extracted at all. The key is when it becomes too expensive to pull oil out of the ground to make it worth doing. This is oversimplified but basically once you take out half of the oil in a given reserve it becomes harder and therefore more expensive to get the remaining half (peak oil). It increases exponentially as you get past the halfway point. So each year past the midway point of removing oil from the ground you are going to end up getting less then the year before and it will cost you more. As we reach that midway point as a planet (which many argue we just recently did or are just about to) oil is going to become more and more expensive. This is why sites that were historically not worth bothering with are becoming financially viable, like oil tar sands. Many of these new sites seem to take more energy to get the oil then that oil can produce. But because oil is become scarce it is becoming financially viable so it's being done.

The trick is that yes it seems that because of some key factors (the economy and better fuel efficiency in automobiles) the US is reducing it's over all oil demand. However many emerging countries are just hitting their stride like we in the US did as we industrialized. These are countries like China and India which have much larger populations then we do here in the US. Because these countries have such large populations they have the potential to dwarf our oil demand in future years. So if we aren't all ready at the midpoint of oil then we are racing there VERY quickly!

Rio 20 - Another Conference


Teamwork 1
Rio 20 - June 2012

It seems like every year or so there is some big conference of nations that is supposed to be the beginning of saving the world. They usually start with a few letter and followed buy a number. G8, G20, Rio 20, etc. Rio 20 is the next of these types of conferences. The interesting twist with the Rio 20 is that it focuses not just on the environment but on sustainable development. It seems idea is that they world is going to grow in population (we just hit 7 Billion and 8 Billion is probably just a little more then a decade away). Much of this population growth seems to be in developing nations. So if we as a planet can get involved and try to get this development to happen in a green way right from the start we can at least stem some of the bad effects that developed nations went through. 


Will it end in Disappointment? 


Like I mentioned it seems that most of these conferences just end in disappointment. Part of the problem though is that they come in with such lofty goals. Like they are hoping that the leaders will come to some kind of conclusive decision on some key point. They really want it to go their way because it will really set the world in motion to being greener, even though they know all the folks with money who back all the campaigns of all these leaders are against it. What do you think is going to happen right? It seems like every time the leaders make it look like it was really close and they say they really wanted to but they just couldn't agree to some small issue and it all fell apart. What a surprise!

So far I haven't heard of any such lofty goals for the Rio 20. So from that stand point it appears its more of just a meeting without specific goals so it would be hard to classify anything as a failure. They really just are saying they are trying to launch a global conversation. Now, don't get me wrong I'm all for this, but at the same time without some kind of concrete goal it hard to see them really getting anything does except for collecting frequent flyer miles and hotel points. I sincerely wish them luck though and hope they succeed. We as a planet really need to shift our thinking and begin to change our actions. We are going to run out of oil and it is going to dynamically change how we live, especially because there are just too many people in the world to sustain without oil energy! The only real question is how early we as a population really realize we are close to this kind of crash. The early we start acting the softer the landing is going to be. If we wait until we just can't afford gas for our car anymore it's going to be a really rough go!

So for Rio 20, and any other conference with some letters and numbers for that matter. I wish you luck but then again its not folks like me you have to convince, it's the folks with all the money that pay for election campaigns!

Dual Flush Toilets - Save Water - Save the Planet

One major area I talk about here on Saving Green is water conservation. There are many area that water conservation touches. Part of it has to do with global warming because newer weather patterns are taking the rain to un-populated areas and leaving populations in drought. Also there is the energy needed to pump the water to your house for use (remember that energy is required even if you have town water, you just aren't directly paying on your bill, but 's built in!). Another area is over population because more and more people are in new homes that are drawing more and more water for a reservoir that is holding less and less water.

Dual Flush Toilets


I found a really cool item that can help when it come to home water conservation and ease the issues with all of the above areas. I've actually heard about these for a little while now but when I saw a conversion kit at the end of the isle at Home Depot this weekend for $20, I knew it was just time!

So the basic concept is that you need much less water to flush urine and a small amount of toilet paper then you do solid waste. I know it sounds gross but when you get over the factor of using bathroom words, it comes down to very basic water conservation. You existing toilet is going to use the same amount of water every time it flushes no matter how much water it really needs. Typically toilets that were manufactured after 1994 use 1.6 gallons per flush (before 1994 I believe it was 3.5 gallons - Yikes!). For solid waste 1.6 gallons is appropriate, but for urine much less will do the trick.

Dual Flush Installation


So I bought the kit for twenty bucks. It claimed that I could install it in 10 mins with no tools. Well I won't say that is really true but it was very basic. I ended up using a screwdriver and a pair of pliers (I also used a battery powered sawzaw but that was just because I didn't want to waste time carefully taking out the old handle and I knew my kids would think it was really cool :).

You just take out the old flapper and handle. Follow a few basic steps and pop in the new mechanism and flush button. Read the directions and do a few basic and quick adjustments to make sure it's flushing how you'd like. Wa La!

There is one round button split into two. The top is for a "quick flush" and the bottom is for a "full flush". Simple as that. In the short run I probably used more water because my kids kept testing/playing with the new flusher. But starting tomorrow we are going to really save some solid gallons.

How Much Will I Save?


They don't give specific stats as to how much the quick flush uses vs the full flush. Although like I say a regular toilet uses 1.6 gallons so I would guess the full flush is the same. I would also ballpark that the quick flush is about half that. Which means every time someone in my family uses that bottom compared to the old flusher we are saving about .8 gallons. Think about how many times you toilet gets flushed in a day. That savings is going to add up!

I have a drilled well so for me the big money savings is the savings on my electric bill because my well pump will kick on less often. But also from a planetary standpoint that is quite a bit less water I'm going to be pumping out of the ground each year.

The box claims that the average family of four will save 15,000 gallons per year if they install this on their most used toilet in their house. They also say that is enough water to be equal to stacking water bottles 45 miles high!

New Dual Flush Toilets


This technology is really catching on. Recently I stayed at a Marriott in Baltimore, MD and noticed they toilet was a dual flush. You can also pretty commonly now buy new toilets with dual flush technology as well.  If you are going to by buying a new toilet anyway then you should pull the trigger on the new technology. Your water/electric bill will be lower and you'll be doing your part to save the planet.

Population and the Environment


1170737
One of the big things I always seem to come back to when I am looking into all the bad things that are going on with our environment these days it that there are just too many humans! Humans do lots of bad things for the environment but one of the major issues with this is that there are just so many of us. If there were far fewer of us then the bad things we do would have a much smaller impact. 



With that thought in mind I was very interested with an article I saw in the Oct 31, 2011 article of TIME called Head Count, which talked about how the world population just hit 7 Billion, and what impacts it is having. Mainly it was a lot of interesting facts that relate to this very topic. I'll give you a few here, they are really interesting stuff!

1. In 1804 the world Population was 1 Billion. So in just over 200 years the world population has gone from 1 Billion to 7 Billion!!!

2. The world population is expected to go to 8 Billion in 14 years, and then 9 Billion in 18 years after that. Yikes!

3. In the history of the world there has been approximately 108 billion humans. That means the 7 billion alive today represent 6.5% of the total history of human population. That is a lot of humans on one planet at the same time!

4. If you put the world's current population in a population density equal to that of NYC, we would all fit in an area the size of Texas. This was actually kind of comforting in a way for me. I mean 7 Billion is way too many, but it put it in perspective that it didn't feel quite so big.

5. 19% of the world's population lives in China. It's scary to think China is one of the emerging industrial countries, and they all ready have rules in place to reduce population growth. That is scary!

6. 50.4% of humans are Male. I just thought it was interesting how balanced this was.

7. 73% of the worlds population doesn't use the internet. I get it when I think about it, but this was very surprising when I first read it. We need to increase this number so more people can read Saving Green :)

8. The US is the third most populated country at 310 million, behind China at 1.3 billion and India at 1.2 billion.
