Industry representatives, government agencies, and organizations, including WWF, gathered in October 2021 at the annual North Atlantic Right Whale Consortium meeting to discuss and arrange right whale conservation efforts in the US and Canada. “It's going to be challenging, but everyone involved in right whale conservation believes we can create an environment where right whales can bounce back，” said Chris Johnson, the global leader for WWF's Protecting Whales and Dolphins initiative. “However, it's going to take significant investment and the greatest urgency and commitment to create conditions where we prevent entanglements and collisions with ships in the whales' critical habitats.” [解题导语]　本文是一篇说明文。本文主要介绍了北大西洋露脊鲸令人担忧的濒危现状以及人类为保护它们所做出的努力。 1．Which of the following best describes the right whale population?
