A new scientific review published in Nature found that marine life has been rebounding in recent years, thanks to conservation efforts, and the oceans could be fully restored by midcentury.

Why it matters: The oceans cover almost two-thirds of the Earth's surface, yet for too long we've treated the waters as a dumping ground.

The oceans are not in great shape. Coral reefs are bleaching, fish are being fished out and microplastics are spoiling the water. Despite that ill treatment, the oceans are more resilient than we thought — and humans have helped.

  • Researchers found that the proportion of marine species threatened with extinction dropped from 18% in 2000 to 11.4% in 2019, thanks in part to conservation efforts.
  • The review authors reported that oceans could be fully restored by 2050 by focusing on rebuilding marine habitats and fighting climate change.

The bottom line: Saving the oceans won't be cheap — the study scientists estimate it could cost $10 billion–$20 billion a year. But the benefits could be 10 times that much, and might just be priceless.

Hong Kong pro-democracy activist Jimmy Lai has been arrested for "collusion with foreign powers," said Mark Simon, an executive at the tycoon's media firm Next Digital Monday morning local time.

Why it matters: He was arrested under the national security law imposed by China in late June that gives Beijing more powers over the former British colony. Lai is the most prominent person arrested under the law, which prompted the U.S. to sanction Chinese officials, including Hong Kong leader Carrie Lam, over Beijing's efforts to strip the territory of its autonomy.

New York reports new low positive coronavirus test rate

New York Gov. Andrew Cuomo (D) announced Sunday 515 people, or 0.78% of those tested, returned a positive reading for COVID-19 the previous day.

Why it matters: It's the lowest single-day positive rate since the start of the pandemic. It's another sign that the state that was once a global coronavirus epicenter is curbing the spread of the virus. "Our daily numbers remain low and steady, despite increasing infection rates across the country, and even in our region," Cuomo said in a statement. "But we must not become complacent: Everyone should continue to wear their masks and socially distance."
