Oils ain’t Oils

I saw this very funny yet poignant video that aired on the Colbert Report about Oil companies and their false environmental credibility. It is about 5 months old, but still relevant.

I am so glad that the oil companies don’t advertise here as much as they do in the US. It would drive me crazy!

Enjoy!

[Ed] I spoke too soon! I just saw a very similar ad on TV tonight from Chevron Australia trying to push their oil induced eco creds down our throats!


Zero Footprint Week – Sustainable Gardening

Earth is here so kind, that just tickle her with a hoe and she laughs with a harvest.  ~Douglas William Jerrold, about Australia, A Land of Plenty

This is the last post in the series and it focuses on something dear to my heart.  Gardening.  My garden, is place of joy and tranquility.  When I spend time working in my garden, I instantly relax and forget about the worries of the world.  I feel connected with what I am doing at that very time and place.  The simple act of planting new seeds or seedlings and watching them grow in the following weeks, fills my heart with a warm glow.  When one of my hand raised seedlings die, a little bit of me goes with it, but when they thrive, I feel strong and filled with a sense of accomplishment.  It is the best feeling to be able to walk out to the veggie patch and harvest the ingredients for a summer salad or meal, safe in the knowledge that you are reducing your food miles and therefore, your carbon footprint. 

So here are today’s tips about reducing your water usage in the garden and decreasing your carbon footprint.

Using water wisely cuts your overall water usage by up to 50%.  Mulch is a wonderful tool to have in your gardening armoury.  It keeps the moisture in the soil, keeps the soil cool in summer and warm in winter.  Think of it as a big blanket for you garden beds.  They also keep weed growth down.  A great book on the subject is "The Miracle of Mulch" by Mary Horsfall, which describe the types of mulch and its many uses. 

Simple things are also effective for saving water.  Checking the weather forecast for possible rain in your area before venturing out to water the garden.  Check how damp the soil is before watering.  The mulch may look dry, but by looking underneath the soil is most probably moist enough and could last another day.

Wicking beds or wicking boxes are a great idea.  They water the plants from the bottom up with a constant supply of water near the root zone.  Hardly any water is lost to evaporation.  Have a look at this video to get a better understanding of the technique.  I will be giving them a go in the next few weeks.  The principle looks simple enough.

Here is another water saving tip I received from Kate over at Hills & Plains Seedsavers.  I think she called it a wicking pot.  I tried it out last weekend, with some amazing results.  What you do is lay your hands on some terracotta pots that are unglazed and unsealed.

Then you plug up the hole in the bottom with silicone (I used a rock and some silicon to stop the water from leaking out.

Then you bury the pot into your prepared garden bed up to the lip leaving about 2 cm above the ground to allow for the mulch.

Wicking pots 003Then you plant you water loving plants around the pot.  Veggies like lettuce, celery that need a lot of water are a good idea.  In this example, I planted lettuce.

Wicking pots 005 They look a bit sorry for themselves as it was a hot day, but they soon recovered.  Water the plants in well and fill up the pot to the top and bung on a lid to prevent evaporation.  Then mulch well around the plants and the pots to keep the moisture in.

Wicking pots 006 Since I planted last Saturday, I have filled the pots twice with water.  All of the lettuces survived the transplant and have new growth.  The pots structure lets the water seep out slowly, therefore keeping the soil moist at all times.  I find that it takes about 3 days for the pot to drain completely, and the soil around the pot out to about 20cm is damp to touch.  Fantastic tip, thanks Kate!  Kate used this method last year, and found that she could pick the lettuce during the heat of the midday sun, and found that the leaves were still nice and crisp.

Other great and easy ideas are reusing your greywater for watering fruit trees and non-root and leafy vegetables.  As long as the greywater doesn’t come in contact with the edible part of the plant, you should be fine.  Watermelons love greywater, as do most cucurbits.  Make sure you wash the produce well when picking after having used greywater just to be sure.  If you do decide to use greywater, ensure that you use an plant friendly laundry detergent with low sodium and phosphorous content.  We use Planet Ark Aware laundry powder, and the plants love it.

If you have the space and the funds, a rainwater tank is a must.  Even though I only have a 2300L tank, it saved my veggie patch last summer.  By only being able to use mains water twice a week, the ground dries out very quickly when the temperature get over 35 degrees C and the rainwater is a godsend.

Cultivating less lawn and more garden reduces garden water usage by 40%.  When I see a well groomed lawn covering an entire front yard, I see wasted energy, time, and money.  Last time I looked you can’t eat a lawn.  I will give you that kids can play on lawns but for all the effort to maintain them, it is easier to take them down the park for a frolic.  Plant vegetables where the lawn is.  Not only do you use far less water, but you get a tangible benefit out of your effort in the form of food.  Front yard vegetable patches are the new black!  Gone are the days of the lush lawn and all the petrol required to mow it.  So by not having to use fuel, or artificial fertilizer you can drastically reduce your carbon footprint by converting that antiquated lawn to vegetable production.

Planting native Australian species reduces garden water usage by another 20%.  I dig native plants.  I have a few that require absolutely no watering at all.  After all, this is the climate they survive in so it comes naturally to these plants to last a long time in prolonged droughts.  I have been trying to get my hands on some local bush tucker plants other than the Lilly pillies that I already have, but the knowledge at the nurseries around here is lacking.  All I got were stupid looks when I asked the other day.  I will have to do a bit of research to see what will survive around here and that is edible.  Wish me luck.

Gardening is a kind of disease.  It infects you, you cannot escape it.  When you go visiting, your eyes rove about the garden; you interrupt the serious cocktail drinking because of an irresistible impulse to get up and pull a weed.  ~Lewis Gannit

Well, sad but true, but today is the final day of Zero Footprint Week.  I hope you all enjoyed the series as much as I did writing it, and I would like to thank the team at One at a Time Foundation for contacting me, in particular Dan, and letting me run with the idea.  I hope all of the tips have been helpful and all I ask is that you have a think some of them, and try and make a difference to your carbon footprint in your part of the world. 

Zero Footprint Week – Transport

Transport: How we get from A to B. 

Before man invented the wheel, the only choices we had were shanks pony (our feet), and riding animals.  Both modes of transport were and still are, extremely low carbon.  Then we invented the wheel which for thousands of years were attached to various types of vehicles that were pulled/pushed by humans or animals allowing for greater loads to be carried.  Once again, very low carbon options.

Then the steam engine was invented in the early 1700’s and it took George Stephenson to put wheels on it in the form of the Rocket,  thus began the industrial revolution and the beginning of the human race’s addiction to burning fossil fuels. 

Then, with the discovery of oil and the refining process, and the subsequent invention of the internal combustion engine, it all quickly went to custard.  Cars were relatively rare early on, and it wasn’t until Henry Ford invented the production line method of manufacturing cars making them affordable to the masses, did the automobile have any real environmental impact.  From that day in 1908, carbon emissions have been increasing exponentially  ever since.

So now we know a little history behind transportation, what can we do to reduce our own personal carbon footprint in this area?  Well here are three tips that will help you achieve this goal.

Walk, Cycle or Use Public Transport
A trip to the shop or the beach can be much more enjoyable if you leave the car at home and walk or cycle.  Not only do you save money on petrol, but you can also save time spent waiting in traffic and looking for a car park.  Also remember that kids have legs, and as they begin to look for more responsibility, let them ride or walk to school instead of you being the local taxi service or if they are too little, then walk to school with them.  I used to have a neighbour who’s drove her kids to the same school as Ben, and when I left for school at the same time as her, I actually used to beat her to the classroom, and then win the race back home as well.  We are only talking 1km here people.  So many people forget to factor in the hassle of parking, that they get much  more stressed than I ever would walking, and all because of pure laziness.  You also would not believe how many people actually drop their kids off in their pyjamas that also live very close to the school.  Obviously, none are too worried about their carbon footprint and too eager to get straight back in to bed when they get home!  Which leads me to the next tip.

Drive Smart
Making sure your car is healthy and planning trips ahead of time for maximum efficiency can save on time, money and carbon.  Planning trips will save you a lot of money.  Why do two trips when one will suffice?  When I go out on errands for Kim, she writes me a list of things to do and get, and the places to visit.  I then map the best route out in my head so that I don’t have to backtrack and waste any fuel.  Also, don’t skip on the maintenance.  Make sure your tires are inflated as per the manufacturers recommendations.  Flat tyres increase rolling resistance, and you burn more fuel.  Regular services ensure that the engine is at peak performance and not struggling by moving thicker dirty oil around its block.  This also burns more fuel.  I also find that by accelerating gently from a standstill, I save a lot of fuel.  In my hybrid, it can make the difference of 2 litres per 100km if I have a lead foot for a few hours.  Just think what that is like in a normal car! 

Choosing your next car on the basis of fuel efficiency also helps. Visit www.greenvehicleguide.gov.au to find out more about choosing a more eco-friendly car.  I have notice of late that there are so many V6 and V8 cars for sale on the side of the road around our town.  Even now that fuel prices have gone down a bit from before the global recession started, people are still ditching these gas guzzlers in droves.  I know it is not because everyone in my town has suddenly become environmental superheroes, it is just that the price of fuel is cutting into the household budget more than it used to.  Even by buying a second hand 4 cylinder car, you will reap the environmental benefits and lower your carbon footprint.

Try Car Pooling
Sometimes you need to drive to work, but why not have some company while you do so?  Driving to work with your fellow employees saves money, fuel and stress on your car.  For more information visit http://www.travelsmart.gov.au/links/.  Hey, what a cool link.  Thanks Zero Footprint Week site!  I have asked so many people in my town who work in the same building as me if they want to car pool, and I always get some lame excuse.  I am quite happy to do all the driving, because I have to pay for the lease anyway and have to do a ludicrous amount of kilometres per year to get a tax benefit.  But, alas no one want to share my green trip in with me :(

I will definitely be checking out the travel smart site to see if there are any tips on getting fellow travellers in my area.  Share the love I say!
