If you haven’t seen the movie "Don’t look up" which shows on Netflix, do it. It is a hysterical movie about an asteroid that is on its way to Earth and man's total denial of the threat of extinction. One can easily draw parallels with climate change and emissions.
If you watch the movie, or at least the trailer, the natural question will be "how can so many people close their eyes when everything it's going to h*ll"? According to Sébastien Bohler, author and specialist in molecular neurobiology, it’s the brain's pleasure and reward center that is the troublemaker here. Its task is to ensure that we move forward day by day, instead of planning for the future. Much like when we lived tens of thousands of years ago and the most important thing was to survive the day. Our brain hasn’t been significantly updated. So even though our brain has evolved evolutionarily with a front part, the neocortex, with an intellect that understands that we need to plan ahead and make wise choices for our future to be better, this more long-term intellect competes with our reward center that shoots out the reward hormone dopamine. It's easy for us to become addicted to the fast kicks. Everything should happen quickly, here and now.
Dopamine itself is not bad, it helps us to experience pleasure, satisfaction and motivation. Like when you have succeeded in something and you feel satisfied, it’s the dopamine that flows in the brain. The problem arises when we become addicted to the kicks and can’t wait for the reward that comes later, or when we can’t think wisely today to create a better future. Due to the brain's tug of war between the will to do the right thing and the desire for reward, we will always be inconsistent and alternate between one moment sorting garbage in the right container, and the next moment indulging in a trip to Spain that eats up our entire carbon budget for the year.
If you regularly increase your dopamine levels, it will be easier for you to also persevere and fight for the more long-term goals. You can increase dopamine quite naturally with:

  • Exercise
  • Cold showers
  • Massage
  • Good sleep
  • Listen to music
