Ecuador – Extreme flooding in the Ecuadoran Amazon has caused widespread disarray along the banks of the Bobonaza River, all amid the COVID-19 pandemic. Over the past couple of weeks, the surging water levels have left hundreds homeless, washing away homes, schools, crops, animals and a bridge in the Sarayaku indigenous community. The floods have also affected the Pacayaku and Teresa Mama indigenous communities.

Yemen – Heavy rains and floods in Yemen since mid-April are affecting 150,000 people, said the UN on Friday. Homes, shelters, roads and bridges were damaged, water supplies polluted, and basic services such as electricity cut because of the disaster. The capital city of Sanaa is the most affected city by the disaster and there has been electricity cut since April 21 in Aden. Underlining that polluted water sources increase the risk of malaria and cholera epidemic, more than 110,000 suspicious cholera cases have been detected in Yemen since January this year.

Highest Ever Level of Microplastics Found on Seafloor

An international research project has revealed the highest levels of microplastic ever recorded on the seafloor, with up to 1.9 million pieces in a thin layer covering just 1 square meter.

Over 10 million tons of plastic waste enters the oceans each year. Floating plastic waste at sea has caught the public’s interest thanks to the ‘Blue Planet Effect’ seeing moves to discourage the use of plastic drinking straws and carrier bags. Yet such accumulations account for less than 1% of the plastic that enters the world’s oceans.

The missing 99% is instead thought to occur in the deep ocean, but until now it has been unclear where it actually ended up.

Researchers have now found that microplastics are delivered to the ocean through rivers carrying industrial and domestic wastewater, carried down submarine canyons by powerful avalanches of sediment (turbidity currents) and then transported on the seafloor by ‘bottom currents’ and deposited in sediment drifts. Other microplastics sink from the ocean surface and can also be picked up and carried by bottom currents.

Record Ozone Hole Over Arctic In March Now Closed

Ozone depletion over the Arctic hit a “record level” in March, the biggest since 2011, creating the largest recoded ozone hole over the Arctic, but the hole has now closed, the UN World Meteorological Organization (WMO) said on Friday.

The springtime phenomenon in the northern hemisphere was driven by ozone-depleting substances still in the atmosphere and a very cold winter in the stratosphere.
