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!
