[00:00:00]Across more [music] than 21,000 rivers worldwide, scientists have detected a major chemical shift already underway. A new study [music] in science advances found that nearly 79% of global rivers are losing dissolved oxygen, the critical element that sustains [music] aquatic ecosystems. Using almost four decades of satellite data, researchers discovered [music] that climate warming is steadily reducing the amount of oxygen rivers can physically hold. And according [music] to the study, this trend is projected throughout the century. So, what's driving it? Which regions [music] are most vulnerable? And how do heat waves and dams intensify the problem? Watch the full breakdown on Environment [music] IP.
