1. This is your most important decision

I had never thought of it that way: «Your choice of career is the most important ethical decision of your life.»

80’000 Hours is a non-profit that helps people figure out how they can best use their career to help solve the world’s most pressing problems. In this new article, they offer a framework anyone can use to make career decisions. Four factors define your impact:

  1. How pressing (or neglected) the problems you focus on are.
  2. How effective the solutions you pursue are.
  3. The amount of leverage you can apply to those solutions.
  4. Your personal fit for the path
This is your most important decision
You have about 80,000 hours in your career: 40 hours per week, 50 weeks per year, for 40 years. This makes your choice of career the most important ethical decision of your life. From adulthood, you’ll spend almost half your waking hours on your career — more than the time you’ll spend eating, on ho…

2. How we fixed the ozone layer

«The most impressive example of international cooperation on any challenge in history» — What can we learn from how humanity dealt with the depleted ozone layer for tackling the climate crisis?

3. How To Be A Girl: The Medical Stuff

Longtime subscribers might remember this wonderful podcast: The story of a six-year-old child, born as a boy, who knew she was a girl from the age of three. Regular updates ended in early 2019, but now there’s an update. On the onset of puberty and what that means for a transgender child.

Episode XXXII: The Medical Stuff

4. To protect the world’s wildlife we must improve crop yields – especially across Africa

The bad news: If things remain unchanged, by 2050 we need additional cropland the size of India and Germany combined to feed a world population of then ~10 billion people. The habitats of thousands of species would be destroyed. The good news: With the right measures taken, we can feed 10 billion people while reducing current land use for crops by the area of India and Germany combined. Insightful analysis.

Bonus: Was wir wirklich über gesundes Essen wissen

In German, but you can always try Google Translate. Über Essen und Ernährung zu lesen ist meistens frustrierend: Ständig neue Ratschläge, die auf wackliger Evidenz stehen, in der Summe nur verwirren und einem jede Freude am Essen nehmen. Nicht so dieser Zweiteiler: Ich hab mich selten so gut informiert gefühlt und gleichzeitig Lust zu kochen (und essen!) bekommen. Teil 1, Teil 2.

What else?

Thanks for reading. Have a nice weekend!
