Here's a simple Thinking Tool for Earth Day. For every day in fact. Five prompts starting with letters that spell EARTH. Simple to remember, challenging to apply. Try it on climate change. Try it on EVs. Try it on plastic, oceans, solar power, smart buildings, warfare, walking. Try it on a personal or professional challenge.

E – Evidence: what are the facts and are they true?

A – Action: what should be done/what can you do?

R – Result: what do we want to happen and why?

T – Tell: who do you need to tell?

H – Help: who can help you and who can you help?

Earth Day is about care, respect and service. It's about valuing the gift of a home and acting to preserve that gift. Our Earth. We've ravaged it and exploited it and scarred it. We've scraped it and pummeled it and heated it - possibly beyond a point of no return. It groans at our demands, it bucks at our excessive needs. It might just kick us off it we're not careful.

But there is hope. Repeated small actions taken by many, many people may just halt the damage-making and begin the repair-making. We should play our part - make decisions in the moment - instant choices to reuse this, repair that, to walk there, to cycle here. Make drops of change that together fill an ocean. And we have a duty to inspire our children to do the same. They walk our legacy, they bear the consequences of our actions.

Here's a short (1:56) summary of the problem and of the growing number of solutions:

You'll find a mountain of Earth Day (22 April) resources online. Overwhelming yet essential. If you want to start simply and effectively, just pick up the EARTH Thinking Tool and help you students apply it. Pick a fact, a video, an opinion, an idea related to climate change and Earth-care, then use the five prompts. I hope it helps. Constructive developmental feedback always welcomed. mi**@th***************.uk
