Never Buy Toothpaste Again! 4 Easy Steps to Make Your Own
I haven't purchased toothpaste in years, and yes, I brush my teeth! How is this possible? I make it myself!
When I transitioned to a zero waste lifestyle more than two years ago, toothpaste was the first product I stopped buying and started making. The ingredients are simple and easy to find at almost any store: baking soda, organic coconut oil and organic essential oils. It takes no more than 2 minutes to combine these three ingredients, and the toothpaste leaves my mouth feeling so incredibly fresh—way fresher than store bought toothpaste. In fact, when I used my friend's store bought toothpaste a week ago, I couldn't believe the difference!
But let's take a step back ... why did I make the switch from “conventional" packaged toothpaste to one that I make myself?
For starters, I live a Zero Waste lifestyle and toothpaste tubes are totally wasteful. They are typically sold with not just the tube, but a box as well. While the box is recyclable, the tube is very difficult or impossible to recycle and will most likely end up in a landfill. The benefit of making my own toothpaste is that I can put it in a glass jar that I can wash and reuse infinitely. No plastic tubes, no trash, no landfill.
I like to have control of what I am putting on and in my body. There is a lot of controversy around the ingredients that are in conventional toothpaste. Two that I will focus on are triclosan and sodium lauryl sulfate, but conventional toothpaste also contains fluoride, propylene glycol and sodium hydroxide, all of which are controversial because they are linked to cancer and a long list of other ailments.
Triclosan: A chemical added to many products to reduce bacterial contamination which is also used in toothpaste to prevent gingivitis,according to the FDA and toothpaste manufacturers. In addition, it has been said to be potentially carcinogenic and have negative effects on the endocrine system in animals. It is banned in certain applications in Europe and in 2011, some of Colgate's soap products were reformulated without the chemical, but not their toothpaste. The ecotoxicology of the ingredient is still under heavy scrutiny and EWG rates it to have a moderate/high health hazard. That's all I needed to hear to make the decision to stay clear of it for good.
Sodium Lauryl Sulfate (SLS): SLS is surfactant (a foaming agent that lowers the tension between two liquids or a liquid and a solid) used in toothpaste to evenly disperse the ingredients and help with effective rinsing and removal of mouth debris. It also promotes foaming. Many studies on SLS show that it is contaminated with 1,4 dioxane, a byproduct of the manufacturing process, which is also a possible carcinogen. SLS is also said to aggravate gums. No, thank you.
If something has a supposed risk, I will avoid it until I have concrete evidence that it is safe. This is why I choose to make my own toothpaste with just three ingredients that I trust and buy packagefree: baking soda, organic coconut oil and organic essential oils.
Toothpaste can cost anywhere between $1 and $8 for a 6oz tube depending on the brand you are buying and where you are purchasing it from. In my experience (purchasing ingredients in NYC), I have spent at most $.60 for 6oz of toothpaste. All aside, the cost savings alone are worth it!
With so much to gain and not much to lose, making your own toothpaste makes sense! It's cheaper to make, tastes better, feels better in your mouth and is better for you. See for yourself, to learn how to make my zero waste toothpaste by checking out this video.
The U.S. District Court of Appeals ruled 2-1 Tuesday saying that the Federal Environmental Energy Regulatory Commission (FERC) failed to adequately review the environmental impacts of the greenhouse gas (GHG) emissions of the fracked gas Sabal Trail pipeline, which runs more than 500 miles through Alabama, Georgia and Florida.
As ocean waters warm and acidify, corals across the globe are disappearing. Desperate to prevent the demise of these vital ecosystems, researchers have developed ways to "garden" corals, buying the oceans some much-needed time. University of Miami Rosenstiel School marine biologist Diego Lirman sat down with Josh Chamot of Nexus Media to describe the process and explain what's at stake. This interview has been edited for length and clarity.
What is killing coral?
I wish we had an easy, straightforward answer for what's killing corals. We know there are many, many different factors influencing coral abundance, diversity, distribution and health these days, but I think the specific answer varies based on where you are.
Temperatures play a major role at global scales, and then you have all of these other, more local factors like disease, physical impacts of storms, or ship groundings.

We had the dredging of the Port of Miami channel a couple of years ago and that caused a lot of localized mortality due to sediment burial and sediment stress. You also have land-based sources of pollution that can damage by location and nutrient influence that causes algal overgrowth of corals.
Local factors are superimposed on regional factors directly related to global climate change. Changes in temperature, more temperature extremes, acidification of the water, changes in storm frequency and sea level rise— all are at different scales — but they all combine to cause coral mortality.
Factors vary both spatially and temporally, but the outcomes are all the same. Regardless of where you are, we've lost a tremendous amount of coral.

In the face of all those threats, can restoration work?
Historically, restoration was developed and used for acute disturbances. A ship runs aground, and so then there's a recovery, and funds are allocated to recovering the reef structure at a given location, and then corals are planted on top of that. But as global conditions decline for coral reefs, there's now a need to scale up. So, we're not just dealing with the localized impact—we're looking at species declining throughout their range.
We need other tools at larger scales, and that's where coral reef gardening has come into play, because it works at larger scales compared to just dumping cement and rebuilding reef structures, costly endeavors that recover just a very small footprint. We're growing and planting these organisms.
Do you worry about planted coral dominating the reefs?
Initially, these techniques were developed for fast-growing corals. The genus that we're focusing on, Acropora, is threatened, so these are very important reef-building species.
When abundant, they monopolize shallow environments. They form thickets, extensive areas of high-density colonies. That's the way they used to grow, until about three to four decades ago when they got wiped out by disease and other factors. The branching corals that we're working with grow between 10 and 15 cm per branch per year, so that's very fast growth.
Through recent advances in coral aquaculture, we're now also able to grow massive species, the ones that grow very slowly. Mote Marine Lab has developed microfragmentation techniques where they can cut coral colonies very, very small and make them grow very, very fast. Although we focused on branching corals initially, now most of the programs, especially here in Florida, are expanding onto other threatened species.

Can these efforts solve the problem, or are they a placeholder until climate stabilizes?
You hit the nail on the head. One of the early criticisms of reef restoration was the scale issue and spending a lot of resources working on a very small footprint.
We've dealt with that now, over the past 10 years we've expanded to the point where we're growing thousands and thousands of corals—we're planting thousands and thousands of corals—so that issue of scale is no longer a valid criticism.
The other major criticism is that, even though we're planting a lot of corals, we're planting them onto environments where the same stressors that caused their initial mortality are in place. Now there is ocean acidification and increased temperatures, so things have gotten, in some cases, progressively worse.

That is a valid concern if we were just planting corals, but we're not just doing that. We're still concentrating on all of the other aspects of reef restoration, setting up marine protected areas to protect fish stocks and coral impacts, working to curb land-based sources of pollution, and setting up sedimentation and nutrient controls. And then, on a much larger scale, we're all trying to curb carbon emissions, trying to limit the greenhouse impacts and acidification impacts. All these tools just help us buy time.
We're also doing a lot of genomics work to see how corals can increase their resilience. A colleague of mine here at the Rosenstiel School at University of Miami, Andrew Baker, is stress-hardening corals. He works on coral symbiosis, and he found that by applying a little bit of non-lethal stress, he can make corals shuffle their Zooxanthellae, which are the endosymbiotic microalgae that provide energy to the corals. In that process, they're able to uptake Zooxanthellae that are more thermally tolerant. So, through the forced shuffling of symbionts, you may be able to buy these corals one or two degrees of tolerance, so that they become more tolerant to bleaching in future years. That is cutting-edge science.
We're trying to actually find out what makes corals survive, and trying to beef up their defenses and their resilience over time. And that's because we have access to all these coral genotypes through the active propagation from coral gardening.

The decades-long struggle for social and environmental justice in the Niger Delta continues, largely unseen by the wider world.
On Aug. 11, hundreds of people from the Niger Delta stormed the Belema flow station gas plant owned by Shell in the Rivers State region of the Delta. The plant transports crude oil to the Bonny Light export terminal, from where it is shipped overseas.
The National Academy of Sciences, Engineering and Medicine said in a statement the Interior Department has directed it to cease its study on the potential health risks for people living near surface coal mines in Central Appalachia.
The Interior Department, which committed more than $1 million to the study last year, has begun an agency-wide review of grants over $100,000 because of the "Department's changing budget situation."
