People have relied on the abundance of the ocean since the beginning of human history. But things are rapidly changing. Scientists project that by 2048 the ocean will be depleted and fisheries will cease to exist. Billions of people rely on fish as their primary source of food and income – a number that will continue to grow over the next few decades as the world population increases. A collapse of ocean fisheries will be a massive threat to the food security and well-being of life on this planet. Nations around the world are pursuing better management practices and sustainable fishing in an attempt to curb this loss… but it is not enough. Despite our efforts, the health of the ocean is decaying even faster than initially predicted. Moreover, we have discovered that overfishing is only part of the problem. To see the bigger picture, we have to go much, much smaller. The whole oceanic ecosystem obtains its energy, food, and nutrients from tiny green phytoplankton – microscopic organisms that play a critical role as the base of the marine food chain. They grow and multiply through the absorption of sunlight – alongside water, carbon dioxide, and micronutrients such as iron.
Phytoplankton are the food of zooplankton, which in turn are consumed by small fish, which are themselves consumed by larger ones and so on. For their health, phytoplankton depend on the natural fertilization of iron-rich winds and upwelling currents, which have been ongoing for millions of years. However, as a result of climate change, winds and currents are changing, and the oceans are getting warmer. This hinders the mixing of surface layers, separating phytoplankton from the nutrients they need to grow. A NASA study has shown a constant decrease of phytoplankton in the ocean… 1% per year since 1950. That means plankton has declined more than 40% in just 60 years. When phytoplankton are in danger, the whole ocean is in danger. Less plankton means less food for fish and other organisms. With the continual decline of plankton, we are facing the collapse of the marine food chain as we know it due to climate change.
The question is: WHAT CAN BE DONE? Over the last several decades, scientists have observed that the iron-rich dust of volcanic eruptions can create massive plankton blooms over deserted areas of the ocean. On several occasions, scientists saw the volume of wild fish in these areas increase significantly – far beyond expectations. Given these observations, experts began to consider what might happen if humans could mimic natural volcanic iron fertilization to boost ocean life. This process is known as OCEAN SEEDING. In a recent Ocean Seeding project, researchers added iron dust to an area of the ocean that was part of the migratory route of juvenile salmon. Only a year later, mainland rivers experienced one of the largest salmon returns in history. Ocean Seeding offers an opportunity to begin repairing the damage to our ocean, rebuild wild fish stock, and improve food security for the growing populations of the world. This vital shift cannot be made without further research in Ocean Seeding and your support. Support us by sharing this video with your friends on social media.
