Happy Earth Day! We hope that you spend sometime offline today with Mother Nature herself.

To celebrate, we're highlighting Makers who are working hard to preserve our planet, especially as climate change is becoming more of an existential threat. We've gathered some of our favorite nuggets of wisdom from these pioneering entrepreneurs:

Loop is a reusable packaging subscription service on a mission to phase out single-use plastics. Global recycling organization TerraCycle is behind Loop, along with big brands like Procter & Gamble, Nestlé, PepsiCo, Unilever and Danone.

“Every day, more and more disposable material gets put in the ocean and landfills, so no matter how much we clean the ocean or recycle we’re never going to solve the problem. To us, the root cause of waste is not plastic, it’s using things once, and that’s really what Loop tries to change as much as possible” - Tom Szaky, TerraCycle CEO

Blueland is creating everyday cleaning products designed to reduce plastic waste through its creative packaging (or lack thereof). They launched on Product Hunt today.

“I decided two years ago to cut back on my plastic consumption, but then realized that many times I just had no choice as a consumer. So many of our everyday goods such as window cleaner, toothpaste and laundry detergent, all come packaged in just one way - single-use plastic. So I founded Blueland with the belief that you don't have to sacrifice a clean home for a clean planet. And to make the biggest impact possible we've focused on making it easy for people to make the right choice with products that are effective, money-saving and convenient.” - Sarah Paiji, Blueland CEO

Sustain makes tampons, condoms and lubricants that are — you guessed it — sustainable. The company uses organic ingredients for all of its products and works with rubber plantations to keep toxins out of the environment.

"The way I think about 'sustainable' products is not just about ingredients, packaging, or how the product will be used and how much energy that consumes. Instead, I think about it based on the products' 'net impact.' For example, condoms are a 'net positive' product because when you compare the supply chain, manufacturing, shipping, using, and disposing of the product, the costs come nowhere near close to outweighing the benefits of helping prevent climate change (overpopulation is one of the largest drivers), the spread of HIV, and the ability for women to plan their family size." - Meika Hollender, Sustain CEO
