Today, river herring populations are dwindling. They were once abundant and spawning in most rivers along the Atlantic Coast, but now there are stringent limits on fishing to get their numbers back up.
Dams block the river herrings’ passage to their preferred spawning location. The slow-moving, warmer water above dams fosters the growth of harmful algae blooms and lowers dissolved oxygen, harming wildlife habitats and overall river health.
“The number one reason that river herring has declined historically is because of dams,” said Rebecca Swadek, the director of wetlands management for the city Parks Department.

The sustainable construction industry is undergoing structural transformation, driven by digital integration, whole life carbon assessment and measurable environmental accountability. Artificial intelligence is being embedded as a fundamental component of sustainable building design rather than a supplementary feature, optimising resource efficiency and supporting rigorous lifecycle assessment. Its greatest barrier remains organisational culture rather than technical capacity.
Carbon management is maturing from aspiration to precision. Companies are adopting advanced methods to quantify embodied carbon in materials, evaluate the carbon footprint of construction and apply life cycle thinking in construction procurement. The shift towards verifiable data supports informed investment and ensures compliance with stricter regulations on embodied carbon and whole life carbon reporting.
Policy pressure on energy‑intensive sectors reinforces the requirement for net zero carbon buildings and broader decarbonising of the built environment. Governments are tightening rules on supply‑chain transparency, life cycle cost evaluation and end‑of‑life reuse in construction as they promote a circular economy in construction. Firms that embed circular construction strategies, low carbon design and sustainable material specification will remain competitive as low embodied carbon materials become critical to achieving net zero whole life carbon.
Certification systems such as BREEAM and the forthcoming BREEAM v7 revision are defining benchmarks for eco‑design for buildings and environmental sustainability in construction, translating ambitions into measurable outcomes. These frameworks align environmental product declarations (EPDs) with resource efficiency in construction, improving building lifecycle performance and supporting the creation of energy‑efficient buildings.
The sector is converging on a data‑driven, system‑wide model of sustainable design. The integration of green construction methods, sustainable building practices and renewable building materials signals a decisive shift towards carbon neutral construction and long‑term sustainability in the global built environment.
