Question 23
23.
Thinking about the Carbon Footprint Calculator activity where we saw how different
things increase our carbon footprint such as:
how many members are in our family,
how much money a family has to spend,
if we choose to eat more veggie and fruit instead of meat, fish and eggs products,
if we purchase products from companies that are ecofeindly or not.
Why do you think our individual actions mater to reduce our carbon footprint instead of waiting for big companies to change their practices first? Explain your thinking in full sentences.
