without clicking on the link, what is the motivation for such an attack?
In this case, meat from the elephant that was poached as the tusks were recovered by rangers from the scene. That in itself is ‘‘understandable’’ as there is very large and very poor community living right on the borders of many of our reserves that are in extreme poverty and not everyone there can go into the local supermarket and buy groceries.
It’s a 5 ton animal and when they had taken what they could, they laced the carcass with poison to kill the vultures who would naturally be gathering in their hundreds, an act of sheer spite. Poachers will say that vultures draw attention to kill sites and might draw ranger activity but that’s all balls because rangers are not going to investigate every time they see vultures circling, it’s a still a vast area and predation kills would still be the cause of a feeding event in the majority of cases. It literally boils down to spite and a lack of education.
The loss of hundreds of vultures in a critically endangered species is devastating as they play a key role in the ecology of the system.

Not really. This is a thought which potentially furthers genocide. No need for that.
@wyld.at.hrt is right: education is the key.

Norway built underwater wind turbines that harness power from ocean currents—without disturbing marine life
Deep beneath the North Sea, Norwegian engineers have deployed a new class of turbines unlike any seen before. Instead of standing above water catching the breeze, these massive structures sit beneath the waves, silently rotating with powerful ocean currents. Dubbed “SeaSpinners”, these turbines offer clean, round-the-clock energy — and a surprisingly gentle presence in the marine ecosystem.
Each SeaSpinner uses a helical turbine design — similar to corkscrews — which allows them to spin regardless of current direction. Anchored to the seafloor, the turbine arrays rotate with slow, consistent motion, harnessing the kinetic energy of deep-sea currents, which are more stable and predictable than wind.
Unlike surface wind farms, these units are shielded from storms, generate no noise pollution, and cast no shadows. Even more impressive, their rotation speed is calibrated to match local marine life swimming patterns — making them safe for fish and whales. Underwater cameras have captured dolphins and seals swimming comfortably through active arrays.
The power generated is transmitted to coastal grids via high-voltage undersea cables. A single turbine cluster can power 25,000 homes, with almost no visual impact on the horizon. Norway’s government is backing full-scale deployment along the Arctic coastline, aiming for 20% of its energy to come from submerged renewables by 2035.
This isn’t just offshore energy — it’s in-sea energy, quiet, constant, and invisible.

Unfortunately, there are similar turbine designs out there, and have been for sometime - the issue with tidal is still capital cost versus output being too high. Wind and PV both had the same problem for at least 25 years.

A carbon-negative concrete made from seawater and bacteria just outperformed cement in strength tests
In a coastal materials lab in Denmark, engineers have created a concrete that doesn’t emit CO₂ — it absorbs it. Made with marine bacteria, crushed seashells, and seawater, this living concrete hardens through biological mineralization instead of chemical heating, making it truly carbon-negative.
The process begins by mixing sand, powdered shell calcium, and a strain of calcifying bacteria. Once the mixture is poured, the bacteria activate in seawater-rich conditions, secreting enzymes that trigger calcium carbonate formation. This natural cementation strengthens over time without emitting greenhouse gases.
Unlike Portland cement — which releases over 1.5 billion tons of CO₂ annually — this formula actually locks carbon into its structure. In strength tests, it exceeded conventional concrete’s load-bearing capacity after 21 days, with better crack resistance and water durability.
The raw materials are abundant and renewable. The system works best in coastal regions, where seawater and marine calcium are easy to source. It’s already being trialed in sea walls, walkways, and low-rise buildings.
With the construction industry responsible for nearly 8% of global emissions, this could be the most sustainable building material ever made.
