A new study in the May 5 issue of Science Magazine shows that human noise pollution has doubled in 63 percent of U.S. protected areas.

Why it matters:

  1. Human disturbances are supposed to be reduced in these protected areas since they're specifically designed to be safe havens for biodiversity.
  2. Noise pollution reduces the ability of prey to hear predators approaching, can interfere with finding mates, and can also affect plants if herbivores change their locations due to excess noise.

The good news: Species listed under the U.S. Endangered Species Act seem to be experiencing about a 56 percent lower noise excess than unprotected areas.

Where to focus mitigation efforts: The authors found that human transportation networks, development, and extraction (think: timber, mining, oil, and gas) correlated with a proximity to cities led to a high noise pollution. Plus, lands managed by local governments had the highest noise levels.

North Carolina can accept absentee ballots that are postmarked Nov. 3, Election Day, until Nov. 12, a federal appeals court decided Tuesday in a 12-3 majority ruling.

Why it matters: The 4th Circuit Court of Appeals' ruling against state and national Republican leaders settles a lawsuit brought by a group representing retirees, and it could see scores of additional votes counted in the key battleground state.
