Natural cork is a sustainable, renewable, and biodegradable material, but many wineries are switching to synthetic corks for their wine bottles. Using a database like CORKWatch, I will choose wines with a natural cork closure, and properly compost or recycle them after enjoying my wine.

An estimated 50,000lbs (23,000kg) of contact lenses end up in sewage sludge in the US each year. This month, I will learn how to recycle used contact lenses and packaging or switch to wearing glasses instead.

There are many benefits to enjoying meatless meals - including reducing our plastic footprint. Most meats and dairy products are packaged in plastic, so this month, I will reduce my animal product consumption and enjoy 1 vegetarian or vegan meals each day.

Using your dishwasher doesn't just save water! I will use my dishwasher whenever possible to extend the life of my sponges and dish cloths, and shed less microfibers from them.

Single-use plastics are everywhere, but that wasn't always the case. I will spend at least 15 minutes learning about the history of single-use plastics and how it became ubiquitous in our daily lives.

Greenwashing can fool even the most experienced eco-advocate. This month, I will spend 15 minutes learning what greenwashing is, how to spot it, and what I can do about it.

The average paperback book has the same carbon footprint of driving about 7 miles (11 km) in an average car. Instead of purchasing new books this month, I will borrow books, e-books, and/or audiobooks from my local library or library-affiliated apps, or host a book swap with my friends.

There's value in our old electronics! This month, I will properly recycle any old laptops, tablets, cell phones, or other electronics I have lying around so the raw materials can be reused and reduce demand for virgin materials - thereby also protecting critical wildlife habitat for animals such as gorillas and forest elephants.

The only thing worse than a single-use item is a zero-use item! I will use (and use up) what I already have in my home before buying something new.

Eliminating 100% of all plastic from our lives simply isn't possible. Throughout this month, I will embrace imperfection in my plastic-free journey while exploring and testing new ways to reduce my plastic footprint.

In the UK, the average person creates 512kg (1,129lbs) of waste in the bathroom over the course of their lifetime - 50% of which ends up in a landfill. As they run out, I will replace my soaps, shampoos, conditioners, and lotions with sustainable, unpackaged, or refillable options.

Whether I'm at work, on the go, or having food delivered, I will keep 1 plastic cutlery out of the landfill per day by using my own reusable cutlery.

Science has shown that focused time in nature calms our over-worked frontal lobe and gives space for the areas of our brain associated with emotions, pleasure, and empathy to take over, providing a sense of calm that is measurable in brain scans and even blood tests. Each day this month, I will spend 10 minutes outside in nature, and share my observations, reflections, and learnings on the Participant Feed.
