EEZ, and so we may underestimate the impact of fishing. In addition, legacy effects of overfishing would not be captured by this analysis, and are likely greatest with habitat-modifying gear and long-lived species that primarily occur along continental shelves and pelagic waters, respectively. ...
Also, the overall number of sea animals has gone down by about half since 1970. In some parts of the ocean, scientists now record fewer animals singing and calling than in the past. Experts say that effects (影响) of noise on sea animals are not well understood. However, some studies ...
rather than being used for agriculture or other purposes. After all, usable water is a scarce resource. Reinforcing the concerns, the Japanese government has admitted that the cumulative effects of discharging the wastewater for 30 years in the ocean are still unpredictable despite the water being ...
Knowing the extent of human influence on the global hydrological cycle is essential for the sustainability of freshwater resources on Earth1,2. However, a lack of water level observations for the world’s ponds, lakes and reservoirs has limited the quant
