A TikTok video by traveling artist Island Life (@vagabondartist) is making waves on the internet, showing why desalination is not always the solution to the water needs of remote regions.

The author of the content lives on a small Caribbean island and explains his decision to collect rainwater instead of using a desalination plant. The reason? It’s not as easy or environmentally friendly as you might think.

“Desalination plants are incredibly expensive,” they stress. But the costs go beyond just money. These plants can have a significant impact on the environment, as they often draw not only seawater but also fish into the sea and kill them.

The process is energy and cost intensive, requiring electricity for pumps and pretreatment systems. For someone like this TikToker who relies on solar power, the electricity demand of a desalination plant is simply too high.

Perhaps the most worrying aspect is what happens after the freshwater is extracted. The leftover brine, which is extremely saline, is pumped back into the sea. This extremely salty waste can be fatal to marine life, killing fish and coral in the area.

This insightful statement highlights the complex challenges of balancing our resource needs with environmental protection, and is a stark reminder that even seemingly simple solutions can have hidden costs.

For coastal communities and island nations struggling with freshwater scarcity, this information is critical and highlights the need for innovative, sustainable water management approaches that do not come at the expense of our marine ecosystems.

The video sparked a flood of reactions online, with many viewers expressing surprise and gratitude for the information.

One commenter wrote: “I was wondering why desalination plants aren’t used near the coast and now I know! Thanks!”

Another chimed in: “Wow, I knew about the pumps and electricity and all that, but what happens to the excess salt never occurred to me. That’s crazy, thanks for explaining.”

Some viewers pointed to possible future improvements and expressed more optimism, with one user noting, “Thankfully with solar getting so cheap, this will become more affordable (still expensive to install though).”

This discussion is a powerful reminder of the importance of understanding the bigger picture when it comes to environmental solutions. Sometimes the most sustainable decision may be the simplest – like collecting rainwater.
