Lesson 4:
KNOWING MY IMPACT AND MAKING CHANGE
KNOWING MY IMPACT AND MAKING CHANGE
This lesson focuses on looking at data trends and using this information to make better choices. Using a carbon footprint food calculator, students will get another glimpse at how their food choices can affect global greenhouse emissions. Students will be tasked to make changes in what they eat based on data from the calculator. They will also begin to think about goals and how to continue to strive for them as St. Paul describes in Scripture.

Atmosphere is the layer of gas that surrounds the earth and is held in place by gravity. The atmosphere consists of several different gases in 5 different layers (stratosphere, troposphere, mesosphere, thermosphere, and exosphere). The atmosphere protects life on earth by absorbing ultraviolet rays from the sun.
Carbon dioxide is a molecule that contains two oxygen atoms and one carbon atom. It can be found as a gas in the air, or as a solid in the form of dry ice, which is very cold. Carbon dioxide is produced from breathing and from burning certain substances called fossil fuels.
Climate change refers to the long-term changes in global temperatures and other characteristics of the atmosphere. Climate has changed throughout the earth's long history, but this time it's different. Human activity is causing worldwide temperatures to rise higher and faster than any time we know of in the past.
Consumption is the act or process of using up something (such as food or coal).
Degrowth is a planned reduction of energy and resource use designed to bring the economy back into balance with the living world in a way that reduces inequality and improves human well-being.
Earth scientist studies the fields of natural science related to planet earth.
Grassroots movements are an organized effort undertaken by groups of individuals in a given geographic area to bring about changes in social policy. Today, grassroots movements work to influence social issues such as racial injustice, reproductive rights, climate change, income inequality, or affordable housing.
Mathematicians are specialists or experts in mathematics who study numbers and how they are related to each other and to the real world. Mathematics is concerned with numbers, data, quantity, structure, space, models, and change.
Overconsumption describes a situation where the use of a natural resource has exceeded the sustainable capacity of a system.
Sustainability is the idea that humans must interact with the environment in a way that ensures there will be enough resources left for future generations.
Revisit the data from last lesson. Ask students: "What were the trends in greenhouse gas emissions students identified in their prediction IF no efforts were made to reduce our carbon footprints?"
Show students the graph from NASA,"The relentless rise of carbon dioxide - Vital Signs if the Planet."
Analyze the graph as a class:
What do they notice?
What are the trends?
Predict why carbon dioxide levels rising at this rate.
How does the data relate/compare to the data examined in the previous lesson?
Ask students: "How do you think your diet affects greenhouse gas emissions?"
Discuss:
Did you know, different foods have a range of effects on the environment?
Think back to all of the learning from the past few lessons, can you recall the foods that had the highest impact on the environment and greenhouse gas emissions? Why?
Which foods do you think have the least impact? Why?
Tell students that in order to make a change we must know our impact. Thanks to data, compiled by mathematicians and scientists, we can see and understand the trends in the natural world are affected by the actions of humans. We have ample data available to us to make informed decisions about what we consume and how our consumption affects the earth.
Have students recall a recent dinner they had. Ask: "What did you eat? What did you drink? Did you have a dessert? Discuss briefly as a whole class.
Introduce the "Climate Change Food Calculator" from BBC News and do a quick read through with them and guide them through the site. (*Note: There is a great deal of information to unpack on this site, allow students time to explore.)
Ask students: "What types of data do you see being used on this site, and how is this data represented?" Discuss their responses as a class.
Revisit the meal students discussed earlier, what was on their plate? Ask students to record the carbon footprint for each of the items on their plate using the "Climate Change Food Calculator."
Ask students to share their environmental impact, by using these (or other) questions to prompt the discussion:
How many kilograms of greenhouse gas emissions were produced in this meal?
What was the equivalent of greenhouse gas emissions in kilometers travelled and how many days of heating for an average home could it provide?
How many showers equal the amount of water used for this meal?
Challenge students to look for ways they could make their meal more sustainable. What substitutions could be made for improved environment and personal health?
Ask students: "Are there connections between healthy choices and a healthy planet? If so, what are they?"
Have students meal plan for one day, using the "Climate Change Food Calculator" to carefully choose what they are putting on each plate to minimize their carbon footprint.
As a class read "35 Easiest Ways to Reduce Your Carbon Footprint" from Columbia Climate School to learn about other ways they can reduce their carbon footprint.
Say: Tackling climate change can seem like a daunting task for any one person. Despite how it may feel at times we are not powerless. In the encyclical Laudato Si, Pope Francis says:
“An awareness of the gravity of today’s cultural and ecological crisis must be translated into new habits” (LS, no. 209).
Explain that changing their eating habits is one thing that they can control and change. Every time they eat a certain way, purchase a certain food, they are unconsciously contributing to greenhouse gas emissions. There are also other areas that contribute to increased carbon footprint which they can control (i.e., transportation, shopping habits, electricity and waste production etc.).
As a class, generate a list of possible goals to reduce their carbon footprint.
Lead the class in a discussion using the questions (or your own) below:
Why are goals important?
What are some barriers or challenges that can get in the way?
What can support you in meeting your goals? (e.g. scripture and prayer)
Say: “In Paul's letter to the Philippians he describes the ability to keep focused and make a commitment to reach an ultimate goal. Paul asks us to use goals to guide our lives as he does to guide his.”
Read the passage together and pray for strength in keeping committed to our goals with God’s help.
12 Not that I have already obtained this or have already reached the goal; but I press on to make it my own, because Christ Jesus has made me his own. 13 Beloved,[b] I do not consider that I have made it my own;[c] but this one thing I do: forgetting what lies behind and straining forward to what lies ahead, 14 I press on toward the goal for the prize of the heavenly[d] call of God in Christ Jesus. 15 Let those of us then who are mature be of the same mind; and if you think differently about anything, this too God will reveal to you. 16 Only let us hold fast to what we have attained.
Have students create a SMART goal for one way they will reduce their carbon footprint (see the weekdone.com SMART Goal template for guidance).
