Every year, one third of all food produced globally goes to waste. This not only affects our wallets but also has a significant impact on our environment. When food waste ends up in landfills, it releases methane gas, which contributes to climate change. We can reduce food waste by buying only what we need, planning our meals, and composting our food scraps. Let's work together to reduce food waste and make a positive impact on our environment. Food waste is a significant problem that affects individuals, businesses, and the environment. According to the United Nations, approximately one-third of all food produced globally goes to waste each year. This equates to 1.3 billion tonnes of food, which is enough to feed three billion people. Food waste has many negative consequences. Firstly, it is a waste of resources. Producing food requires land, water, energy, and other resources. When food is wasted, these resources are also wasted. This is not only bad for the environment but also ...
The impact of global climate change ,as we all know, cannot be denied.
The green snow has lined a considerable quantity of southern continent's snow.
This is not white, but green.
It has been foretold that within the coming years, the green snow is probably going to unfold across continent – a results of hotter temperatures and global climate change.
The conditions required for algae to bloom within the space are because of water , that is available in ample quantity in Antractica, because the planet is heating up therefore apace.
To conduct the study, the researchers checked out satellite information gathered between 2017 and 2019 and combined it with on-the-ground measurements over 2 summers in continent. That method allowed the scientists to map the microscopic algae as they bloomed across the green snow of the peninsula, consistent with CNN.What is rumored is really a conservative estimate since the information solely enclosed chlorophyte. The satellite is barely capable of memorizing green snow, which implies the information unheeded the red and orange algae that accompany it.
"The algae blooms in continent ar adore regarding the quantity of carbon that is being omitted by 875,000 average United Kingdom hydrocarbon automobile journeys," Davey same to Reuters. "That appears heaps however in terms of the world carbon budget, it's insignificant. It will take up carbon from the atmosphere however it will not build any serious dent within the quantity of dioxide being place within the atmosphere at the instant."
A new study printed within the journal Nature Communications on Wednesday found that the green glow within the snow is really caused by a microscopic algae blooming on the surface of the snow, consistent with CBS News.
The researchers from the University of Cambridge within the United Kingdom and also the British Antarctic Survey say the algae can unfold because the planet heats up as a result of warming temperatures are making additional of the slushy conditions that the algae want so as to thrive, consistent with The Guardian.
Where the algae are at their most dense, their bright inexperienced shine alters the looks of the snow and is really visible from house.
The scientists conjointly say that because the protoctist spreads, it'll invite in different species that may feast thereon as a potent supply of nutrition, because the Guardian rumored. To conduct the study, the researchers checked out satellite information gathered between 2017 and 2019 and combined it with on-the-ground measurements over 2 summers in continent.
That method allowed the scientists to map the microscopic algae as they bloomed across the snow of the peninsula, consistent with CNN. The information was gleaned from pictures collected by House of Agency satellites with measurements from Antarctica's Ryder Bay, Adelaide Island, the Fildes dry land and King martyr Island.What is rumored is really a conservative estimate since the information solely enclosed chlorophyte.
The satellite is barely capable of memorizing green snow, which implies the information unheeded the red and orange protoctist that accompany it. "We currently have a baseline of wherever the algae blooms and that we will see whether or not the blooms can begin increasing because the models recommend within the future," same Matt Davey of the University of Cambridge's Department of Plant Sciences to Reuters.
Even though mosses and lichens ar the dominant plant species in continent, the new mapping known one,679 separate algae blooms that ar a key element within the continent's ability to capture dioxide from the atmosphere, as Reuters rumored."The algae blooms in continent ar adore regarding the quantity of carbon that is being omitted by 875,000 average United Kingdom hydrocarbon automobile journeys," Davey same to Reuters.
"That appears heaps however in terms of the world carbon budget, it's insignificant. It will take up carbon from the atmosphere however it will not build any serious dent within the quantity of dioxide being place within the atmosphere at the instant." The green snow seems on the Antarctic coast, that ar "warmer" areas.
There, the typical temperatures reach simply higher than freeze within the summer.The researchers found that the distribution of inexperienced snow protoctist is powerfully influenced by marine birds and mammals, as a result of their waste is an efficient plant food. Over sixty p.c of blooms were found close to sphenisciform seabird colonies, et al. were found close to birds' nesting sites, consistent with CBS News.
"This may be a vital advance in our understanding of land-based life on continent, and the way it would amendment within the coming back years because the climate warms," same Davey in an exceedingly handout.In order to flourish, the protoctist want a prepared offer of water, that they must have Associate in Nursing ample quantity of because the planet heats up and snow on the continent dry land melts.
"As continent warms, we have a tendency to predict the general mass of snow algae can increase, because the unfold to higher ground can considerably outweigh the loss of little island patches of algae," same co-lead author Dr. Saint Andrew grey, of the University of Cambridge and also the University of capital, as CBS News rumored.And the algae can facilitate additional snow soften."It's terribly dark — a green snow algae bloom can replicate regarding forty five p.c of sunshine touching it whereas contemporary snow can replicate regarding eighty p.c of the sunshine touching it, therefore it'll increase the speed of snow soften in an exceedingly localized space," same grey to CNN.
To achieve bigger accuracy in their results, the scientists supplemented information from the house Agency’s watcher a pair of satellite with measurements from the sphere. info from the satellite, that measures specific wavelengths of sunshine mirrored off the Antarctic surface, may be hampered by inclemency and false signals that would be misread as chlorophyte, says Saint Andrew grey, the paper’s lead author.
As far as eating snow goes, don’t try the white stuff. Researchers in Canada found in 2017 that melting urban snow releases a cocktail of toxic chemicals, largely from car exhausts, trapped in the snow from polluted air. Snow in its beauty has always exercised a hold over our imaginations, symbolising purity and transcendence, harking back to a mythical state of innocence. As the snow around us stains black, grey, brown, green and the rest, there could hardly be a more potent emblem of our runaway global problem with pollution.
A team of U.K. scientists recently created the first-ever large-scale map and estimate of the extent of green algae on the Antarctic Peninsula — a mountainous extension that stretches more than 800 miles toward South America and has experienced one of the most rapid rates of warming in the world. The study results, published in the journal Nature Communications, show that the “green snow” is a significant carbon sink for the continent, absorbing approximately 479 tons of carbon a year through photosynthesis.
The researchers found that the distribution of green snow algae is strongly influenced by marine birds and mammals.
Over 60 percent of algae blooms were found near penguin colonies, and others were found near birds' nesting sites.
The green snow has the capacity to refelct only 45 percent of light whereas the white snow reflects about 80 percent of light hitting it.As the result of growing algal (green snow) bloom , the snow will further melt at high speed.
This microscopic algae had spread so much that it is now visible from the space.
This is a big concern and can have a long lasting treacherous impact on the planet.
