How do we reach climate jsutice?

I personally believe that the main obstacle in our way of reaching climate justice is getting every person on Earth on board with the steps we need to take. It’s extremely hard for people to let go of habits that they have been practicing for so long that are actually affecting the planet in a negative way. For example, driving cars everywhere and buying unethically sourced goods. Therefore, if we can get people to stop buying things just to buy things and stop revolving their life on what they have, we might be able to halt climate change and reverse the damage we have done to the planet.
