I created some new photo art this morning. 2 new pieces; 1 b/w piece here.
They're visual contrasts between devastating logging #clearcuts & world famous #OldGrowth tree, Big Lonely Doug. These creations are sparked by my lifelong love of ancient #forests & the need to keep protecting them, against government lies & #ecocide industry greed.

"As transportation networks expand and urban areas grow, noise from sources such as vehicle engines is spreading into remote places. Human-caused noise has consequences for wildlife, entire #ecosystems and people. It reduces the ability to hear natural sounds, which can mean the difference between life and death for many animals, and degrade the calming effect that we feel when we spend time in wild places."
Today's topic.... #movies
Only in second place in the last vote
But we all love movies, don't we?

It seems that, as with the introduction of new animals (#neobiota, e.g. rabbits to #Australia) the introduction of new plants( #neophytes*) can be a huge source of disruption regional #ecosystems as well.
After reading through the aforementioned article about #grasslands, I now begin to understand the complexities involved.
Europe is not prepared for rapidly growing climate risks
#Europe is the fastest warming continent in the world, and #climate risks are threatening its energy and #food security, #ecosystems, #infrastructure, #water resources, financial #stability, and people’s #health. According to the European Environment Agency’s assessment, published today, many of these risks have already reached critical levels and could become catastrophic without urgent and decisive action.
‘Revolutionary’: EU Parliament votes to criminalise most serious cases of ecosystem destruction
"Countries will have two years to put the updated directive, which covers crimes 'comparable to ecocide', into national law. Ecosystem destruction, including habitat loss and illegal logging, will be punished with tougher penalties and prison sentences under the EU’s updated environmental crime directive."

#Flowers grown floating on polluted waterways can help clean up nutrient runoff
Cut-flower farms could be a sustainable option for mitigating water pollution.

"Flowers grown on inexpensive floating platforms can help clean polluted waterways, over 12 weeks extracting 52 percent more #phosphorus and 36 percent more #nitrogen than the natural nitrogen cycle removes from untreated water, according to our new research. In addition to filtering water, the cut flowers can generate income via the multibillion-dollar floral market.
"In our trials of various flowers, giant #marigolds stood out as the most successful, producing long, marketable stems and large blooms. Their yield matched typical flower farm production.
Why it matters
"Water pollution is caused in large part by runoff from #farms, urban #lawns, and even #septic tanks. When it rains, excess phosphorus, nitrogen, and other chemicals wash into #lakes and #rivers.
"These nutrients feed #algae, leading to widespread and harmful #AlgaeBlooms, which can severely lower oxygen in water, creating 'dead zones' where aquatic life cannot survive. Nutrient runoff is a critical issue as urban areas expand, affecting the health of water #ecosystems.
"Water pollution is an escalating crisis in our area of Miami-Dade and Broward counties in #Florida. The 2020 #BiscayneBay fish kill, the largest mass death of aquatic life on record for the region, serves as a stark reminder of this growing environmental issue.
How we do our work
"We study sustainable agriculture and water pollution in South Florida.
"Inspired by traditional floating farm practices, including the #Aztecs’ #chinampas in Mexico and the #Miccosukees’ tree island settlements in Florida, we tested the idea of growing cut flowers on floating rafts as a way to remove excess nutrients from waterways. Our hope was not only that the flowers would pay for themselves, but that they could provide jobs here in Miami, the center of the US cut-flower trade.
"We floated 4-by-6-foot (1.2-by-1.8-meter) mats of inexpensive polyethylene foam called Beemats in 620-gallon (2,300-liter) outdoor test tanks that mirrored water conditions of nearby polluted waterways. Into the mats, we transplanted flower seedlings, including #zinnias, #sunflowers, and giant marigolds. The polluted tank water was rich in nutrients, eliminating the need for any fertilizer. As the seedlings matured into plants over 12 weeks, we tracked the tanks’ improving water quality.
"Encouraged by the success of the marigolds in our tanks, we moved our trials to the nearby canals of Coral Gables and Little River. We anchored the floating platforms with 50-pound (22.7-kilogram) weights and also tied them to shore for extra stability. No alterations to the landscape were needed, making the process simple and doable.
What still isn’t known
"The success of the giant marigolds might be linked to the extra roots that grow from their stems known as adventitious roots. These roots likely help keep the plants stable on the floating platforms. Identifying additional plants with roots like these could help broaden plant choices.
"Future raft designs may also need modifications to ensure better stability and growth for other cut-flower and crop species.
What’s next
"Our promising findings show floating cut-flower farms could be a sustainable option for mitigating water pollution.
"One of us (Locke-Rodriguez) is expanding this research and working to scale up floating farms in South Florida as a demonstration of what could take place in the many locations facing similar issues worldwide.
