The players’ association co-founded by Novak Djokovic has filed an antitrust lawsuit against the women’s and men’s professional tours, the International Tennis Federation and the sport’s integrity agency.

In 2010, more than 150 countries agreed to goals to protect nature, but the new United Nations scorecard found that the world has largely failed to meet 20 different targets to safeguard species and ecosystems. Reducing "everything on the planet to single scores” obscures the fact that the picture may look different in different places, he said. But Mrema and lead author David Cooper said the world should think about a different poster animal: humans. One of the challenges in meeting global biodiversity targets is a mismatch between countries with abundant natural assets — such as large tracts of intact tropical forests — and those with money to enforce protections. Dalhousie University marine biologist Boris Worm, who also wasn’t part of the report, said the world is at a crossroads.
