Not only are humans changing the surface and temperature of the planet, but also its sounds – and those shifts are detectable even in the open ocean, according to research.
Changes in the ocean soundscape affect wide swaths of marine life, from tiny snapping shrimp to huge right whales, the researchers found.
Many fish and marine animals use sound to communicate with each other, to locate promising locations to breed or feed, and possibly to detect predators.
But increased noise from shipping traffic, motorized fishing vessels, underwater oil and gas exploration, offshore construction and other human activity is making it harder for fish to hear each other.
China's Tianwen-1 probe has sent back its first image of Mars, as the mission prepares to touch down on the Red Planet later this year.
The spacecraft, launched in July around the same time as a rival US mission, is expected to enter Mars orbit around February 10.
The black-and-white photo was released by the China National Space Administration showed geological features including the Schiaparelli crater and the Valles Marineris, a vast stretch of canyons on the Martian surface.
The photo was taken about 2.2 million kilometres (1.4 million miles) from Mars.
The five-tonne Tianwen-1 includes a Mars orbiter, a lander, and a rover that will study the planet's soil. China hopes to ultimately land the rover in May in Utopia, a massive impact basin on Mars.
