Food Production, Food Miles and the Green House Effect.


The Greenhouse Effect.

Did you know that every time we transport something, the engine of the boat, train, truck or plane that is used gives out invisible gas called CARBON DIOXIDE. This gas is making an invisible force field around our planet that is keeping too much heat in our planet. Heat should be able to move away into space so that the Earth can cool down. But all the CARBON DIOXIDE gas we humans are making is trapping the heat and our planet is heating up. Also Animals and decaying food waste make METHANE gas which also causes the Green House Effect.

This means ice melting in the north and south poles and animals like Polar Bears have no home and are becoming endangered.


As the ice melts it makes the oceans bigger. More water and more heat makes MORE TYPHOONS. These cause a lot of damage. The picture below is the Philippines after Typhoon Yolanda when you were in Grade One.



Food Production, Consumption and the Greenhouse Effect.

But did you know that the food you eat can lead to more Carbon Dioxide and Methane and cause more Green House Effect? Its also known as Global Warming and Climate Change. Here are some ways that happens.

1. Animals that are part of Food production cause the Green House Effect.

The Animals that become food or who produce food like dairy make lots of Methane. Also their food that we feed them leads to lots of Carbon Dioxide when it is being produced. Look at the data handling infographic below! What does it tell you?


Here is another. What conclusions can you make?



2. The food that you buy and eat usually has to be transported.

The food that you eat has to be transported. Sometimes from nearby. Sometimes from VERY far away. The engines of the different vehicles used to do this all produce CARBON DIOXIDE gas. Some types of vehicle produce MUCH more than others. If they were not being used to transport food, these vehicles would NOT be using their engines.

Look at the data handling info-graphic below. You can click on it to make it bigger. Which forms of transport produce the most Carbon Dioxide?



This is sometimes called Food Miles.


Now for the big questions!

What can you do to reduce how much your food, your families food and ISM’s food causes Climate Change?

What things do you do already or that other people you know are doing?

What could you do?

What WILL you do?

See if you can finish the sentence starter with some real things that you can do.

I can stop climate change and I will stop climate change by……………..



Notes for teachers………….




This model is called Harts ladder of participation. We want the action to be student led so that they may become aware of their ability to bring meaningful change to the world. But you can guide and suggest too.



Its Ok to model what YOU do!




The Community Garden is there as a resource for you to practically inquire into the merits of locally produced organic produce.

Safe Guardians of the World.


This year our Elementary School Music Department, through the Grade Four Children’s Musical Theatre group produced a performance entitled ‘Safe Guardians of the World.’ The ‘Big Idea’ of the production was SUSTAINABILITY. The performance was organised in the same way that the Compass Point method of analysing life on our planet is organised with four main elements (N)ature, (S)ociety, (E)conomy and (W)ellbeing.


The themes of ECONOMY  are mainly about how sustainable the production of food and things we need are, along with levels of waste and saving. In the production a wasteful Queen was shown a more sustainable path by a green hero who encouraged her to conserve more and distribute her wealth more evenly.



The theme of ‘SOCIETY’ was illustrated through a second scene where a group of friends where in a social ‘bubble’ which was surrounded by a kind of invisible force that prevented awareness of the world and other groups that were outside of the bubble. New people were unable to join and connect. Community came to the rescue, puncturing the bubble and uniting the groups together.


The third scene featured the theme of NATURE. This took the form of a dance off, set in a forest in Bohol between machines and native species of tree and animals like Tarsiers for example. The Big Idea in this scene is a key idea behind sustainability and it is the simple truth that we are not separate from nature. We are all one. One can even take this view of the Universe as a whole as the atoms that make up life in our planet where primarily created in the centre of stars many light years away!


The final section on WELLBEING was about balance and friendship. It was about being more mindful of placing connection as more important than competition. A scene was acted out with students acting as characters in a Go Kart computer game. At the end of the race the winner decided to prioritise making sure that their fellow competitors felt ok rather than focussing on celebrating victory.


At the end of the performance some children stayed behind for a questions and answer session with the curator, narrator and performers. There were many questions about how the CMT group had organised the performance over the four months since preparations began.


There are also important questions to consider about the Sustainability theme. Perhaps it would be good for us all to consider………….

-How do you connect with Sustainability?

-How could you connect with Sustainability?

-What could you do?

-What will you do?

ISM Community Gardens Project

In 2009 students, teachers and parents from ES, MS and HS all joined hands and built our ISM Community Garden! Since then we have been learning more about plants, making friends from all over our school and solving problems together.

Service Partners

By learning more about the people in our community we are able to help each other solve problems like trash, floods and poverty. Click here to find out more about our Service Partners, who they are, what they do and how you can get involved!
