For faithful readers of this opinion page, you already know my summary of current research — Florida’s springs are dying by a thousand cuts. Many of Florida’s artesian springs already flow intermittently and some not at all.

Excessive groundwater pumping from more than a million wells is the root cause of this decline in springs health. Almost all of Florida’s springs are also polluted by harmful nitrate nitrogen levels, resulting from excessive fertilizer use and inadequate wastewater treatment. Dams strangle some of our mightiest springs and excessive recreation smothers many others.

I was witness to a recent presentation by Mary Christina Wood via Skype to the attendees of the University of Florida law school’s biannual Public Interest Environmental Conference in Gainesville. Wood, with the University of Oregon’s School of Law, presented a compelling vision of the disastrous effects of global warming if humans do not take their forward-thinking responsibility seriously.

We have heard that average world-wide temperatures are increasing and that an inevitable consequence of this warming trend is the melting of glaciers and a resulting rise in sea levels. After absorbing Wood’s talk about climate-change feedback loops and tipping points with no mercy and no second chances, it appears that too few of us are taking climate scientists’ dire predictions of a warming planet seriously enough.

For example, none of us seem worried about finding higher ground with sea levels rising less than one-eighth of an inch each year. Even old folks can hobble fast enough to keep their feet dry if that is the worse we can expect. But Wood’s talk posed a much harder question for us all: “What would we do if we learned that our grandchildren will not be able to survive to old age if we fail to act now to stop the rise in atmospheric greenhouse gases?”

But how can we be sure a sacrifice we make today will make a difference in the distant future? That is why evolution gave us brains and the ability to understand cause and effect. We can be sure that some disasters that will directly affect the quality of our grandchildren’s lives in the distant future will be prevented or at least mitigated by actions we take today.

Cutting our use of groundwater today has the immediate and long-term effect of improving the health of Florida’s springs and environment tomorrow. Keeping our fertilizer use to an absolute minimum improves the quality of groundwater that nourishes springs and our bodies for years. Driving a fuel-efficient car, recycling paper and plastic and planting trees reduce our carbon footprints, inevitably slowing the rate of global warming.

Experts are predicting that the collective and focused actions of all humanity can prevent the destruction of the world’s environment. Government regulations and public education have the power to positively influence the decisions of millions of thoughtful citizens. In any emergency, the best time for action is immediate.

The springs won’t turn themselves around. Neither will the world’s climate. Only humans were given the foresight needed to change the course of history.
