There are geologists who believe our planet would be better named Ocean rather than Earth. 71% is water, a fact that astronauts have visually appreciated. Life of all kinds no matter what we call our home, is critically dependent on the health of our oceans, lakes, and rivers. Oceans provide 50 to 80% of our oxygen via the plankton that dwell there according to NOAA (National Oceanic and Atmospheric Administration)** Rain can also be traced back to evaporated water from Earth. The inhabitants of many countries would not survive without fish.
Usually, we cannot see the damage to oceans, lakes, and rivers caused by climate change. The trash on beaches is disgusting, but can be picked up before it contaminates the ocean . However, those who follow the News have been alerted about the Red Tide of algae killing 15 tons of dead fish that recently washed up on Tampa Bay with more to come. This time the ocean has fought back. I can’t imagine the stench. This tragedy echoes 2018 when 20 tons of dead sea life washed ashore. Ancient sea turtles, manatees, dolphins, and more lost their lives. Humans living nearby suffer from respiratory illness. Businesses depending on tourism are suffering economically.
The main culprit is fertilizer that has washed into waterways and ultimately the ocean. In addition, the rises in temperature in air and water contribute to the growth of the red algae. The only potentially positive aspect of these disasters is their high visibility. Plankton are also dying off at a rate alarming to marine scientists, but most of us don’t notice. Plankton not only provide oxygen, they absorb carbon, and are at the bottom of the ocean’s food chain.
With heat waves on the west coast and severe flooding in Europe, I am heartened that more politicians are no longer ignoring the dangers of global warming, but I won’t celebrate until aggressive plans are in place to save our planet. Protestors point out that there is no planet B. I am also heartened that scientists and activists are working hard on solutions so much so that all that is needed now is the public will to get our government to act.
**I saw the head of NOAA appear on PBS’s Climate One hosted by Greg Dalton. She described appearing before a Congressional committee in charge of funding. When she mentioned the critical role of NOAA in tracking the weather, one committee member replied that if he wants to know about the weather, he just turns on TV. I didn’t know whether to laugh or cry. I wonder how she was able to contain her poise in explaining to the unidentified gentleman where TV gets their weather information.
