 With this breakfast, Dwayne 'The Rock' Johnson is in top form - Muscle Building Breakfast Dwayne Johnson has not made a secret that he for his superhero debut in comic filming "Black Adam" (Start: Summer 2022) as hard as never trained. As a superhero, the ex-wrestler has never been to be seen on the screen, so not only damped DC fans are looking forward to the comic film adaptation. Due to the Corona pandemic, the production of action film had attracted for about two years - a real challenge for all involved.

Bangladesh ranks seventh for countries most affected by extreme weather in the past two decades, according to the Global Climate Risk Index. Farmers are desperately trying to adjust to these ever more destructive and unpredictable conditions caused by global warming -- from using floating seed beds to developing salt - resistant rice .

Rural Bangladeshis are having to adapt to survive . Historically, people in Bangladesh had worked around seasonal flooding; farming for part of the year Where rice might have once grown, shrimp farms are taking over – the saltwater providing the right environment to switch to aquaculture. While scientists might develop saltwater- resistant crops in time, and some Bangladeshis will find work in

Rising sea levels and violent flooding are already putting tens of millions of lives at risk in Bangladesh, but they bring another problem that threatens the entire nation: Water-logged land and high salinity in streams and soil are killing crops.

How Queensland's strawberry growers planted a $100k prize to help solve a labour crisis

  How Queensland's strawberry growers planted a $100k prize to help solve a labour crisis Queensland strawberry growers are crediting a "pick and pack" competition for warding off their worst labour crisis on record and saving the season.Each season, Queensland produces about 42 per cent of Australia's annual strawberry crop, with a farm gate value of $435 million last year.

Floating farms are common not only in Bangladesh , but also in parts of Myanmar, Cambodia and India. Due to difficult climatic conditions, regular floods and floods in these countries, floating gardens have literally become a salvation for rural farmers and the only way to continue growing food. They believe that the Bangladeshi floating farm model can offer a solution to the food problem in the parts of the world most affected by flooding due to climate change. Scientists suggest that such farms can guarantee food security for individual households. Mission impossible - grow food with little or no soil.

In Bangladesh from July to October, rivers rise, but farmers are learning to grow crops and raise animals even when the floods come. If you can create floating schools, why not floating farms ? From VOA Learning English, this is the Agriculture Report. Rivers in northwestern Bangladesh rise sharply during the rainy season causing months of flooding on farms and villages. This hurts the rural poor who depend on agriculture to survive . When the floods cover their lands they cannot grow crops or raise animals.

"Even 25 years ago, we could grow crops throughout the year... but then water started to stay here seven months. We were clueless how to survive," Altaf Mahmud told AFP.

"Most of the farmers here are poor and the land is scarce. But if we can't grow anything during the seven months, we would starve," neighbour Mohammad Mostofa added.

So they and other local farmers in Mugarjhor, a region 200 kilometres (120 miles) south of Dhaka, revived a century-old technique of using seed beds that sit atop the water.

Floating farms , salt - resistant rice : Bangladeshis adapt to survive .

"No matter how deep is an ocean, a boat always floats at the top." - Listed on Nasdaq stock market | Symbol: $VMAR. Join the conversation. Rice is grown submerged in water not because it needs that much water, but because it can survive being in water. It's a sure way to prevent pests.This way, you don't even need to flatten out an area for farming .

They stack layers of water hyacinth and bamboo tied together by their roots to create a raft, between two and four foot high, on which to plant seeds -- often using wood chippings and coconut coir as a fertiliser.

This forms a light, floating vegetable garden -- bitter gourds, spinach and okra can all be grown this way -- able to rise and fall with the water levels.

The floating farms have become community initiatives, in some villages, women spend months preparing the beds before boatmen take them across water-logged fields, old beds are composted.

Ever-more frequent cyclones, rising sea levels, floods, erosion, drought and unreliable rains have already displaced millions, either into city slums or abroad.

Those that stay have no choice but to find new ways of working.

adaptation ; how do and will communities continue to adapt to the challenges of living in the Sundarbans? - in some areas, salt - resistant rice crops are being grown - this will help with sea level rise and flooding - building houses on stilts is aiding to protect housing - non-intensive farming ensures that fragile environment remains usable for future generations.

Finding staple foods such as rice that can survive an unreliable water supply is essential to the world’s long-term food security. So, too, is finding ways to make the use of water in all areas of agriculture more precise and efficient. The scale of the challenge is vast. From developing strains of rice that are more resilient to drought, to obtaining invaluable satellite data on water loss, farmers and researchers are rethinking agriculture to create a food system less vulnerable to a changing climate.

Some farmers have stopped growing crops opting instead to grow shrimp in the brackish water, or crab-fattening -- capturing wild crabs and feeding them up to then sell -- as well as rearing ducks, which fetch a high price in Dhaka eateries.

Bangladesh Rice Research Institute (BRRI) have created new salt-resistant varieties of the staple crop.  

"Normal rice does not grow in saline water.  Salinity saps the energy of rice stalks," explained scientist Alamgir Hossain.

BRRI has now created a strain that can grow in water with triple the saline levels that normal rice can cope with, he said. 

This has offered "new hope" to farmers in coastal regions, where seawater is increasingly encroaching the land, he added.

But Saiful Islam, a climate expert at Bangladesh University of Engineering and Technology, said such efforts are a drop in the ocean.

"We need to build new roads, preserve rain water and create alternate livelihoods for millions of people. Just inventing crops won't do. Bangladesh alone can't do it," Islam told AFP.

He added that Western nations were "responsible for emitting most of the greenhouse gases" and so needed to help.

Islam said Bangladesh received "barely any" of proposed $100 billion dollars set aside by developed nations for adaptation to and mitigation of climate change.

In some regions, it is ordinary people leading the charge for change. 

"Lungi" Jakir has become a local legend for his hands-on battle against climate change. 

A former construction worker, he and friends built an embankment to stop seawater breaching a 6.5-kilometre (four-mile)freshwater canal -- effectively saving the 43,000 people it serves in Pakhimara, in southern Bangladesh. 

It requires continual repair, but has ensured there's enough fresh water year-round to irrigate traditional crops and even try new ones. 

Poland's 'priceless' primeval forest pits environmentalists against state

  Poland's 'priceless' primeval forest pits environmentalists against state Stopping by a giant oak tree in Europe's largest surviving primeval forest, environmental journalist Adam Wajrak pauses in admiration. - Carbon reservoir - Strolling deep in the forest, Wajrak stopped to pull some hairs caught on a tree trunk. "A bison has passed here," said Wajrak, who works for the Gazeta Wyborcza daily.An emblematic animal for Poland, bison were hunted for centuries and disappeared from Bialowieza, its last habitat in Europe, before World War II. They were reintroduced using specimens reared in zoos.

"Salinity is all around us," he told AFP, "We got very little assistance from the government... so we have to find our own ways to survive."

"I could migrate to the cities. But I know how hard it is to live in a city slum."

Jakir said he "learnt new farming techniques from YouTube", detailing how they now also use plastic sheeting and raised beds to protect the top soil. 

The initiative has been such a success that the area has gone from growing only pumpkins and lentils to supplying fruit and vegetables to other districts and even workers at the nearby coal-fired power station.

Authorities admit farmers have shown them new possibilities for climate challenges. 

"We thought hyacinth is a weed and should be thrown out of the ponds but it has opened up a vast opportunity of farming," Mohammad Shahidullah, a former government agriculture chief for Mugarjhor, said of the floating vegetable gardens. 

"The state-run research institutes didn't know anything about it. We learnt from the farmers here," he added.

Officials are keen to "popularise" the technique in other water-logged regions, explained Shahidullah.

Farmer Mahmud said some of his family were now being recruited by the government to train others in this form of soil-free agriculture. 

Vegetable grower Mostofa was hopeful they can weather the changing climate. 

He told AFP: "Now thanks to the floating farm, we can grow our food and also sell the surplus."

Dems Vowed to Soak the 1%. Now They Want to Give Them a Tax Cut. .
If Democrats have been consistent on anything, it’s been their promise to make the wealthiest Americans pay their fair share in taxes. Joe Biden campaigned on rectifying the unfairness of the U.S. tax code. So did Bernie Sanders. And most of the lawmakers populating the Democratic majorities in Congress—from Sen. Joe Manchin (D-WV) to Rep. Alexandria Ocasio-Cortez (D-NY). With their control of Washington, Democrats finally had an opportunity to fulfill this long-running promise and, in doing so, provide a much-needed source of revenue for their trillion-dollar social spending package.
