FLASHCARDS: QUICK EASY EARTH DAY TIPS
Welcome back to Math! Science! History!, where we explore the big ideas that shape our world. I’m your host, Gabrielle, and today we’re taking a global look at something very close to home, our planet. This Earth Day we’re going to talk about real, practical things people around the world are doing to make the Earth a better place.
From Copenhagen to Cape Town, from Vancouver to villages in Vietnam, today’s episode is full of tips you can apply, no matter where you live, how much money you make, or how busy your schedule is.
Let’s begin in Denmark, a global sustainability leader.
🌍 Segment 1: Denmark, A Model of Clean Living
In 2025, Denmark ranked at the top for eco-friendly living. And what’s most inspiring isn’t just their policy, it’s how much of the action starts in everyday households.
Danes have embraced wind energy so fully that it powers over 50% of the country’s electricity. But individuals also play their part, by reducing meat consumption, biking instead of driving, and investing in home energy retrofits like better insulation and heat pumps.
Want to take a page from Denmark’s book? Here’s what you can do:
- Switch to LED lighting.
- Insulate your windows, even DIY with thermal curtains.
- Invest in wind or solar shares if you can’t install panels yourself.
- Opt for a bike or walkable commute once a week, just one day makes a difference.
And most importantly: share what you’re doing with your friends. Did you know that in Denmark, climate action is contagious. I’ll talk more about that later.
🇮🇳 Segment 2: India, Local Solutions at Scale
India faces monumental environmental challenges, but it’s also home to some of the most creative solutions. In Tamil Nadu, students use banana leaves instead of plates. In Pune, a women-led cooperative runs one of India’s most efficient waste-sorting programs, serving over 500,000 households.
If you’re feeling overwhelmed, take this tip from India: start small, and make it collective.
- Host a neighborhood swap or repair day.
- Learn how to compost at home, even in a small space.
- Reuse fabric or old clothes before tossing them.
And if you’re in an area without city compost services, consider partnering with local farms or community gardens who often accept kitchen scraps.
🇨🇦 Segment 3: Canada, Building a Greener Infrastructure
Let’s head to Canada, where cities like Vancouver and Toronto are investing heavily in green buildings and public transport.
Vancouver, especially, has a bold plan: they want to be the greenest city in the world. They’re getting close, with more electric buses, zero-emissions building requirements, and urban rewilding projects that bring pollinators back into city life.
Here are some lessons we can learn from Canada:
- Support local policies that fund public transport and clean energy.
- Start a pollinator garden, even a window box helps.
- Petition or ask to have your building, school, or workplace cut emissions.
And don’t forget: advocacy is powerful. One email or one phone call to your city council, really matters.
⚡ Quickfire Round: Everyday Eco Tips with Global Roots
Let’s do a quickfire blitz of five things you can start today, inspired by countries across the world:
- Japan: Separate your recyclables, even better, reduce packaging altogether.
- Germany: Embrace the “repair culture”, fix it before you toss it.
- Kenya: Ditch plastic bags. They’ve been banned nationally since 2017. Use woven or reusable ones instead.
- South Korea: Get serious about food waste. Freeze scraps for compost, or join a food-sharing network.
- Netherlands: Rethink your travel. Trains, bikes, even walking all beat car emissions.
Remember: you don’t have to do everything, just pick one and build from there.
🧠 Segment 4: Science, Math & Behavior Change
You might be wondering, what does math and science have to do with all this?
Well, it turns out behavioral science plays a huge role in sustainability. A 2021 study showed that when people see their neighbors installing solar panels, they’re more likely to do the same. It’s called the social diffusion effect, and it’s measurable.
Another neat stat: a single person who switches to a plant-based diet can reduce emissions by nearly 1 ton of CO₂ per year. That’s the same as not driving a car for six months.
These numbers may seem small, but when multiplied by millions of people? That’s exponential change.
🧑🔬 Segment 5: The Business of Climate Survival
Let’s talk money. Green habits aren’t just good for the planet, they’re good for your wallet.
- Induction stoves use 5–10% less energy than gas.
- Home composting can reduce waste disposal fees.
- Energy-efficient appliances often come with rebates and tax credits.
And on a bigger scale? The green economy is exploding. By 2030, clean energy jobs are expected to outnumber fossil fuel jobs worldwide.
So, what’s your place in this green economy? Maybe it’s a side hustle in repairing clothes. Maybe it’s starting a rainwater garden. Maybe it’s just sharing this episode with someone else.
🚪 Closing Thoughts: Your Front Door is the Starting Line
Earth Day doesn’t live on a calendar. It starts at your front door, in what you eat, how you move, how you vote, and how you teach.
If everyone who listens to this podcast took one new action this week, we could inspire ripple effects around the world.
So here’s your challenge:
🌱 Pick one tip from today.
📆 Do it this week.
📣 Tell one friend.
And then? Celebrate it. You’re not just one person. You’re part of a global chorus singing for the Earth. Keep taking care of this beautiful blue planet we all call home!
