Interconnectedness between Land & Ocean Healing

You know how every part of your body is connected to the other parts? How if you injure the left side of your body, your right side has to overcompensate? Or how when you break your wrist you can feel  pain in your shoulder or back as it has to move differently to accommodate the injured wrist?

Well, planet Earth has been feeling all that interconnectedness too, and operates quite similarly. Current times are seeing an injured planet, that is working really hard to repair itself in mysterious ways - to heal both the ocean and the land.

Some of our planet’s injuries are new, like the COVID-19 pandemic that will take us some time to figure out how to repair from its devastating effects.

Other injuries, like deforestation, have been going on for decades. The slower rate of unfolding has tricked many people into thinking it isn’t also a critical injury that needs immediate attention. Like all anthropogenic increases in carbon emissions, the deforestation rates, which are totally out of hand, are directly affecting the health of marine life in our oceans. The land is injured - so the ocean is overcompensating and getting injured in the process.

What is ocean acidification?

Our planet’s forests store massive amounts of carbon. When we cut the forests down, the carbon is released into the atmosphere. And then, the ocean comes to the rescue (doesn’t it always?) by absorbing the atmospheric carbon

We have to admit, it’s really sweet of the ocean to lessen atmospheric CO2, but it’s doing so at its own expense. Marine biodiversity, the food chain, and other ecosystem processes are deeply impacted. The ocean is used to storing carbon - in fact, it is the world’s second largest carbon store and holds 18% of the planet’s carbon (1)

The sudden anthropogenic increase in atmospheric - and now oceanic - carbon levels, however, is way more than the ocean is used to storing. This sudden increase in carbon is lowering the pH of the ocean. Since the industrial revolution’s fossil burning frenzy began, the ocean’s pH has dropped by about .1 units. By the end of 2100, it is expected to drop by .3 units! This 150% increase in ocean acidification is happening at a really fast rate (2).  It has been millions of years since the ocean has had this type of composition, so you can imagine this makes it difficult, if not impossible, for marine life to adapt to this new environment. 

We call this ocean acidification because the excess carbon in the saltwater is lowering the ocean’s pH, making it more acidic than it has been in a million years (3).

Increasing water temperatures

Beyond ocean acidification, the warming up of global temperatures is also warming up the ocean’s temperature. The global temperature is expected to rise by 2° by 2050 (moderate predictions say by 2100), which is warmer than it has been in the last 420,000 years (4)! Most of marine life, as we know it, has evolved into its modern state during that time span. The effects of this dramatic increase in temperature slows current circulation and decreases primary productivity, threatening many of our beloved marine species (5).

The parts of the ocean that are experiencing the warmest increase in water temperature, happen to coincide with areas of greatest marine biological diversity. As these biological hotspots are experiencing the most pronounced increase in water temperatures, their marine animal populations are suffering. These areas have extensive economic dependence on fisheries, so their economies are suffering too. These biological hotspots demand extensive efforts towards ocean healing, to save the biodiversity and economies of these areas. 

Effects on marine life

Phytoplankton is often an oceanic indicator of environmental health. Their large population sizes, coupled with their quick cell division and reproduction rates gives them the advantage of rapid evolutionary change. 

Everyone is wondering - will they be able to evolve quick enough to the rapid acidification and temperature changes?

Phytoplankton is at the base of many different food webs. They are food for jellyfish, young fish like herrings, and feed larger zooplanktons which feed so many marine animals! If the bottom of the food chain is unhealthy, there are rippling effects seen throughout entire ecosystems.

Additionally, the photosynthesis produced by phytoplankton plays a critical role in balancing atmospheric carbon and oxygen levels. As large producers of oxygen (up to 50% of the atmospheric oxygen is produced by our ocean’s phytoplankton!), their health is of utmost importance (6).


As the trees release the excess carbon in the air, and oceans absorb more and more of this carbon, there is a direct adverse effect on calcifying organisms such as mollusks, shellfish and coral. There simply is a reduced amount of available carbonate ions that these organisms need to produce their shells and skeletons made of calcium carbonate.


When coral reefs are under stress, like from rising ocean temperatures, they release zooxanthelon - which is their main source of energy. The release of this algae leaves them with an eerie, bleached skeleton and often leads to their death. This devastating phenomenon is known as coral bleaching. And it is one of the most known devastating effects that calls for a mass effort towards ocean healing.

For the last thirty years or so, corals have had some thermal tolerance to the increased ocean temperatures, thus mitigating some bleaching. This protective mechanism, however, is suspected to disappear with just a .5° increase in temperature(7). As mentioned earlier, climate is expected to rise by 2° in the next 30-80 years as a delayed reaction to the massive deforestations. Not only does this threaten the spectacular coral reef itself, but the entire ecosystem that depends on them for their livelihood.


Fish and many marine mammals are being affected by ocean acidification and warmer water due to irregular food distribution, changing migratory patterns, and disappearance of habitat (like coral reefs and sea ice)(8). Perhaps most visibly, the arctic marine mammals are suffering greatly from the melting of glaciers. Narwhals, bowhead and beluga whales, and polar bears are significantly affected by this loss (9), and urge us to focus on ocean healing.

Unsurprisingly, the planet’s diverse ecosystems are all interconnected. We need to collectively care about the whole, so that our favorite places can thrive. When one aspect of the planet is injured, there are unintended consequences that show up all over. We need to have a systems-thinking approach to make the change we want and provide space for land and ocean healing.

The ocean is a powerful place. A healing place. A place for fun and play. And a place for lessons and challenges. 

Did you know seaweed has incredible therapeutic and culinary uses?

 How can you contribute to the ocean healing? 

Plant Trees = this will directly help store carbon from the atmosphere, making less of a burden for the ocean so it can heal

Support regenerative agriculture practices = this type of land management focuses on rebuilding soil - where most of the world’s carbon is stored. 

Support businesses that care about the ocean & the forests = There is only so much we can do alone. We need to turn to our community and it’s businesses to make larger scale change. Support social enterprises that give back to our planet.

If you choose to eat seafood or fish, make sure you choose sustainable options. Here is a blog post to help you navigate the best options.
