Salmon run

Salmon will soon swim freely in the Klamath River for first time in a century once dams are removed

| By | -, Change Milestones

The largest dam removal project in U.S. history is nearing completion. Crews will use excavators this week to breach rock dams that have been diverting water upstream of two dams that were already almost completely removed, Iron Gate and Copco No. 1. The work will allow the river to flow freely in its historic channel, giving salmon a passageway to key swaths of habitat just in time for the fall Chinook, or king salmon, spawning season.

Ecuador river is granted the right to not be polluted in historic court case

An Ecuadorian court has ruled that pollution has violated the rights of the Machángara River, which runs through the capital of Quito. In some parts of Latin America and North America, inhabitants have constitutional rights to a clean environment, but Ecuador is one of the few countries that recognize the right of natural features not to be degraded or polluted.

Plastic pollution in the water

Plastic-choked rivers in Ecuador are being cleared with conveyor belts

| By | -, Change Milestones

Created by the tech start-up Ichthion, the Azure system’s simple design has the capacity to stop and collect around 80 tonnes of plastic per day. The Azure system is a boom device that stretches across the river to stop objects floating on the surface. It extends two feet down into the water, allowing fish and other organisms to move freely below and is placed at an angle allowing the natural water flow to direct all debris into one corner of the riverbank.

| By | Change Milestones

Since it was founded in 2015, the Trees for the Future (TREES) mass reforestation campaign has convinced and enabled thousands of farmers to plant tens of millions of trees every year. The program spans nine African countries ranging from Senegal and Mali to Tanzania and Kenya. In less than 10 years, it has reportedly restored a combined area of more than 41,000 hectares, which is about seven times the size of Manhattan.

U.S.-China collaboration creates the cheapest and fastest way to desalinate seawater yet discovered

“For the first time, it is possible for water, produced by sunlight, to be even cheaper than tap water,” said Lenan Zhang, a research scientist from the team from MIT and Shanghai Jiao Tong University. “This opens up the possibility for solar desalination to address real-world problems.”
