Taking Care of the Planet Is Taking Care of Your Future

(Opening – calm and reflective tone)
Good morning, everyone. My name is Pablo, and today I want to share a simple but important lesson: Never judge a book by its cover.

That phrase doesn’t only apply to people or books — it applies to the world around us, too. Sometimes, we look at our planet and think it will always be fine, or that nature will “fix itself.” But that’s just the cover. The truth inside is very different.

Definition and Nature of Learning

Learning is defined as an enduring change in behavior mechanisms resulting from experience. It is crucial to understand the difference between learning and performance: performance changes do not necessarily indicate learning, and learning can occur without visible performance improvements.

Associative Learning involves forming associations between stimuli/events (CS-US) or behavior and outcomes (R-S). Learning can be conscious or unconscious (procedural/implicit learning) and supports emotions, motivations, decision-making, and survival adaptation.

Types of Learning

• Associative Learning: Predictive learning is observed in performance, but changes in performance do not

Small-Scale vs. Large-Scale Risk Aversion

The core idea is to understand the differences between how small and large changes in wealth affect risky gambles.

Diminishing marginal utility (risk aversion) primarily applies to large-scale gambles. This is because the utility function is sufficiently concave over lifetime changes in wealth. This concavity results in a higher utility for taking a certain outcome than for taking a gamble, even if the gamble has a higher expected return.

However, for small-scale gambles, the utility function is locally linear, yielding almost risk-neutral behavior. For wealthy individuals, the utility function is very weakly concave, leading to an asymptotically linear curvature. Thus, diminishing marginal utility cannot...
