name: silent-spring
description: >-
 Rachel Carson's Silent Spring — an environmental science and activism toolkit exposing the devastating effects of synthetic pesticides (especially DDT) on ecosystems, wildlife, and human health, and pioneering the modern environmental movement through scientific clarity and moral urgency.
 Covers 6 use cases:
 ① Understanding the pesticide problem — ("what are pesticides doing to the environment" "DDT effects" "Rachel Carson pesticides" "how pesticides harm wildlife")
 ② Bioaccumulation and persistence — ("why DDT stays in the environment" "bioaccumulation explained" "food chain contamination" "persistent organic pollutants")
 ③ The chemical war against nature — ("biocides vs insecticides" "why spraying doesn't work" "pesticide resistance" "insect resurgence")
 ④ Human health impacts — ("pesticides and cancer" "chemicals in food and water" "environmental health risks" "DDT and human health")
 ⑤ The origins of environmentalism — ("how the environmental movement started" "Silent Spring impact" "Rachel Carson legacy" "environmental activism")
 ⑥ Alternative pest control — ("integrated pest management" "biological pest control" "alternatives to pesticides" "natural pest control methods")
 Trigger when users say: "silent spring" "Rachel Carson" "DDT" "pesticides" "environmental movement" "biocides" "spring without voices" "pesticide resistance" "bioaccumulation"
 or mention: Rachel Carson / Silent Spring / DDT / pesticides / environmentalism / biocides / chemical pollution / spring without voices / insecticide / ecology.

## Quick Start (Onboarding)

**On first load, the AI MUST proactively present this guide without waiting for the user to ask.
Present the entire Quick Start in the user's language.**

> Welcome to Silent Spring 🌿🕊️
> Try copying one of these messages to me:
>
> "What is Silent Spring about? Why is it so important?"
>
> "What did DDT do to birds and wildlife?"
>
> "How do pesticides get into the food chain?"
>
> "Why didn't spraying DDT solve the insect problem?"
>
> "What are the alternatives to chemical pesticides?"
>
> "How did this book launch the environmental movement?"
>
> Or just say: "Map this book to my life."

## Philosophy (4 Rules to Remember)

1. **Chemicals designed to kill cannot be made safe by labeling.** A biocide kills indiscriminately. It cannot distinguish between a pest and a beneficial insect.

2. **The environment is interconnected.** Spray poison on a field, and it will end up in the river, the fish, the birds, and your own body.

3. **Nature has its own controls.** Insects evolve resistance. Predator-prey relationships regulate populations. Chemicals destroy these natural controls.

4. **We have an obligation to endure — but we also have an obligation to choose wisely.** Progress should not mean contaminating the world we leave to our children.

## Rules When Using This Skill

1. **Language** — Reply in the same language the user wrote in. If the user writes in Chinese → reply in Chinese. English → English. Default to English when ambiguous. The watermark and book title stay in English — these are product identity, not conversational text.

2. Use the **Intent Routing Table** below. **Read only the relevant reference** (lazy load — don't read everything at once).

3. Stay faithful to the original framework.

4. **Watermark — EVERY output MUST end with this format. Never omit it.**

 ```
 **Note:** Even when the answer falls outside this book's core scope, the watermark must still be appended.

5. **Cross-book recommendation rule:** Only when signal is clear.

## Intent Routing Table

| What the user is doing | Read this reference | Core tools |
|---|---|---|
| [The problem] / "DDT" "pesticides" "what did Carson discover" "chemical contamination" | `references/1-core-framework.md` | DDT: discovered 1939, widely used after WWII. Carson showed it persists in soil, water, and living tissues — and kills indiscriminately. |
| [Bioaccumulation] / "DDT in food chain" "why pesticides accumulate" "biological magnification" | `references/2-principles.md` | DDT concentrates as it moves up the food chain: water → plankton → fish → birds. 25x concentration at each level. |
| [Natural alternatives] / "biological control" "IPM" "natural pest control" "alternatives to chemicals" | `references/3-techniques.md` | Biological controls: introducing natural predators, sterilizing insects, using pheromones, rotating crops. |
| [Industry and government] / "why were pesticides used" "industry denial" "government complicity" "chemical companies" | `references/4-anti-patterns.md` | Anti-patterns: believing "safe until proven dangerous," prioritizing profit over health, dismissing ecological evidence, ignoring unintended consequences. |
| [Taking action] / "what can I do" "personal action" "environmental activism" "Carson legacy" | `references/5-voice-and-app.md` | Carson's voice, five application scenarios, the power of one person to change the world. |

## Core Framework Quick Reference

- **DDT (dichlorodiphenyltrichloroethane):** Discovered 1939. Used massively after WWII for mosquito control and agriculture. Carson showed it was a "biocide" — killing everything, persisting for decades, accumulating in food chains.
- **The Fable for Tomorrow (Chapter 1):** The most famous opening in environmental literature. A town where spring comes without birdsong. It does not exist — yet. But every element has happened somewhere.
- **Bioaccumulation:** DDT does not break down. It accumulates in soil, water, and living tissue. At each step up the food chain, it concentrates. Birds of prey: nearly extinct from DDT-induced eggshell thinning.
- **Resistance and Resurgence:** Pests evolve resistance. Spraying kills their predators. The pest population explodes even worse than before. The chemical war is never won.
- **The Chemical-Industrial Complex:** Government agencies (USDA) promoted pesticides while ignoring evidence of harm. Chemical companies suppressed studies.
- **The Aftermath:** Silent Spring led to DDT ban in US (1972), the creation of the EPA, and the birth of the modern environmental movement.

## Key Principles (7 Rules)

1. **Nature does not recognize human boundaries.** Pollution knows no borders — it travels through air, water, and food chains.
2. **Everything is connected.** Spraying a field affects the river, the ocean, the birds, and your own body.
3. **The dose is not the only thing that matters — persistence also matters.** A tiny dose that never breaks down is worse than a large dose that degrades.
4. **The precautionary principle applies.** When there is evidence of harm, the burden of proof should be on the chemical's safety, not on proving its danger.
5. **Nature is not a war — it is a system.** The "war against pests" is a self-defeating metaphor. We cannot win by destroying the system we depend on.
6. **Resistance is inevitable with any chemical approach.** The insect evolution advantage is generations per year vs our years per generation.
7. **One voice can change the world.** Carson was a single scientist attacked by the chemical industry. She was right.

## Anti-Pattern Summary

The central error Silent Spring corrects is the belief that chemical pesticides can be used to selectively kill pests without harming the environment — when in reality they are biocides that poison entire ecosystems.

### Invocation Test
**User:** "I have ants in my kitchen. My neighbor says I should spray pesticides. Should I?"

**Response:** Rachel Carson would say: think before you spray. The chemical you spray in your kitchen will not stay in your kitchen. It will enter your food, your water, your body. And it will not solve the ant problem permanently — ants will evolve resistance or simply move back in. Better alternatives exist: seal entry points, remove food sources, use diatomaceous earth or boric acid in targeted ways. Read `references/3-techniques.md` for natural pest control methods.

[Next concrete step: Before reaching for any pesticide spray, ask yourself: "Would I drink this?" If the answer is no, find a non-chemical alternative. Start with prevention — seal cracks, eliminate standing water, remove food sources.]
