But there are alternatives....
Campaigners say consumption such as travel, gifts and food are destroying planet and the meaning of Christmas
Whether out of poverty or virtue, many of us spend much of the year reining in our appetites to save our pennies and our health. But at Christmas many of us put our worries aside and go wild in an orgy of lavish gifting, extensive travel and a gluttonous feeding frenzy.
This carnival of consumption has a cost: not just to our wallets and our waistlines, but also to the climate.

From the Flask glacier to King George Island, intrepid researchers expect good cheer, snow and penguins
Many of us will not get a white Christmas this year, but a group of scientists are guaranteed one while carrying out research on the Antarctic peninsula.
While ice and good cheer are expected, their yuletide activities will be very different from those back home. Dr Kate Winter, of Northumbria University, and colleagues will be deploying instruments on Flask glacier to study the way that meltwater affects how quickly glaciers flow into the ocean.

Betchcott Hill has glorious views across the county and a mix of habitats home to curlew, cuckoo and lapwing
One of the most scenic and nature-rich spots in western England could be protected for ever in a boost for the curlew, cuckoo, lapwing and snipe that nest there.
Betchcott Hill has views across much of the county and its mix of grassland, wet flushes, woodland and heath sings with the calls of endangered birds in spring.
This article was amended on 24 December 2024 to correct the size of the site, which is 50 hectares, not 50 acres.

Aldro, North Yorkshire: The ‘major lunar standstill’ only happens every 18.6 years, and once upon a time it would have been an unavoidable event
There’s a place a short drive from home where I’m often drawn to watch the sunset. It’s been special for thousands of years – a high point on a pre-Roman trade route and a gateway to the chalklands of the Yorkshire wolds. The area is thick with prehistoric archaeology, including mounds, cursuses and earthworks.
Here at Aldro, the banks of a vast bronze age ditched enclosure would once have stood out white against both land and sky. It is a truly spectacular vantage point, with unobscured views west and north across the vales of York and Pickering to the dales and the moors. From here it is also possible to see almost all the setting stations of the sun as they track north in summer, south in winter, falling fully west only during the spring and autumn equinoxes.

Subsidence affecting many new builds, raising questions about sustainability of skyscrapers in coastal areas
Miami’s oceanfront skyscrapers are sinking. In 2021 the devastating collapse of the Champlain Towers South condominium in Miami’s Surfside resulted in the loss of 98 lives, and prompted closer inspection of the city’s high-rise shoreline. Now a study has identified unexpected levels of subsidence among many of Miami’s high-rise buildings, including prominent luxury properties such as the Porsche Design Tower, Trump Tower III and Trump International Beach Resort.
Using satellite data gathered between 2016 and 2023, researchers observed between 2cm and 8cm of sinking of buildings along Miami’s beachfront area. One beachfront – Sunny Isles Beach – recorded continuous subsidence in more than 70% of its new builds. The findings, published in Earth and Space Science, show the majority of affected buildings were recently constructed high-rises. Which means it is possible the subsidence is a consequence of their own construction. The combination of hefty high-rise buildings, vibration from construction, groundwater movement and tidal flows are potentially triggering the subsidence, with the worst-affected areas being those with a sandy layered limestone underlying them.

With restrictions due next month, food vendors are still using such plastics and some traders have not heard of ban
Labake Ajiboye-Richard, the founder of a Lagos-based sustainability consultancy, was driving in Nigeria’s most populous city earlier this month when she saw someone throwing rubbish out of their car window.
“I was so shocked to see that in 2024,” she said. “If you’re throwing something on the road, what are you doing in your home? What are you doing in your community?”

While some residents take to building houses in trees, officials recognise need for national response to climate disasters
Every summer, Dongting Hu, China’s second-largest freshwater lake, swells in size as flood water from the Yangtze River flows into its borders. Dams and dikes are erected around the lake’s edges to protect against flooding. But this year, not for the first time, they were overwhelmed.
For three days in early July, more than 800 rescue workers in Hunan province scrambled to block the breaches. One rupture alone took 100,000 cubic metres of rock to seal, according to Zhang Yingchun, a Hunan official. At least 7,000 people had to be evacuated. It was one of a series of disasters to hit China as the country grappled with a summer of extreme weather. By August, there had been 25 large floods, the biggest number since records began in 1998, reported state media.

The death of Tanaru, the last member of an uncontacted group in the Amazon, raises questions about ethnic cleansing of Indigenous people, justice and the future of ancestral lands
For at least 26 years a man known as Tanaru lived alone in a small forest in the south-western Brazilian Amazon, moving around his territory, building several houses, planting crops and hunting. He also dug large, mysterious holes inside his homes.
When a team from the National Indigenous Peoples Foundation (Funai) came across him in 1996, he resisted contact, aiming an arrow at them through a gap in his palm shelter, a scene captured in the 2009 documentary Corumbiara. In 2007, Funai officials made another attempt at contact. Again Tanaru repelled it, leaving one man with a bad arrow wound.

Večernji obroci mogu utjecati na metaboličko zdravlje, upozorava nedavno objavljena studija. Naime, konzumirati više od 45% dnevnog unosa kalorija nakon 17 sati, može pridonijeti višim razinama glukoze u krvi kod starijih osoba s predijabetesom ili ranim dijabetesom tipa 2, a loše regulirana razina glukoze u krvi može tijekom vremena pridonijeti razvoju dijabetesa tipa 2, većem kardiovaskularnom riziku i kroničnoj upali.
U novoj velikoj studiji otkriveno je da su genetske varijante koje povećavaju mogućnost disleksije povezane s razlikama u područjima mozga koja su uključena u motoričku koordinaciju, vid i jezik.
Ispijanje više šalica kave tijekom dana može pomoći u sprječavanju kognitivnog pada kod osoba s fibrilacijom atrija, ukazuju rezultati novog istraživanja. Inače, fibrilacija atrija je najčešći poremećaj srčanog ritma u odraslih osoba koji povećava rizik od demencije.
Nova studija pokazala je da se plazmatske razine proteina znanog kao placentni faktor rasta (PlGF), potencijalno mogu koristiti kao biomarker za probir i praćenje kognitivnih oštećenja i demencije.
Prema rezultatima nove studije dodatak stereotaktičke radioterapije tijela (SBRT) sistemskoj terapiji sorafenibom značajno poboljšava preživljenje bez progresije bolesti (PFS) i vrijeme do progresije u bolesnika s lokalno uznapredovalim hepatocelularnim karcinomom.
Rezultati nove studije pokazali su da većina hranjivih tvari dobivenih iz jaja (lecitini, apolipoproteini i nezasićene masne kiseline) nije povezana s povećanim rizikom od pretilosti. Iznenađujuće, većina istraživanja sugerira da te hranjive tvari smanjuju vjerojatnost pretilosti putem regulacije metabolizma lipida.
Poznato je da sleep apneja pridonosi srčanim problemima, dijabetesu i bolestima jetre. No, čini se da ona također ima izravne učinke na zdravlje mozga, pokazuje nova studija. Naime, pokazalo se da osobe sa sleep apnejom doživljavaju ubrzano starenje bijele tvari mozga, koja služi za povezivanje različitih regija mozga.
Rezultati nove studije ukazuju da zanemarena vrsta neizravnog oštećenja mozga pridonosi trajnoj invalidnosti nakon moždanog udara. Naime, pokazalo se, da je talamus - neka vrsta središnjeg mrežnog čvorišta koje regulira funkcije kao što su jezik, pamćenje, pažnja i kretanje - pogođen mjesecima ili godinama nakon što je osoba doživjela moždani udar.
Znanstvenici upozoravaju da su ljudi koji žive s neurodegenerativnim bolestima poput demencije ili Parkinsonove bolesti posebno osjetljivi na pogoršanje zdravlja uslijed toplinskih valova zbog većeg rizika od komplikacija povezanih s vrućinom.
Unatoč medicinskim smjernicama koje podržavaju upotrebu antivirusnih lijekova kod male djece s dijagnozom gripe, nedavna studija izvješćuje o premaloj upotrebi spomenutih lijekova. Inače, gripa čini do 10% svih pedijatrijskih hospitalizacija tijekom zimske sezone.
Doba u kojem živimo obilježeno je sve bržim promjenama koje se name?‡u morskom okolišu, a gotovo za sve odgovorni su ljudi. Obalna zona Sredozemlja, pa tako i našeg Jadranskoga mora, mjesto je na kojemu obitava više od polovice ukupnog stanovništva Mediterana te zbog toga ovo usko područje predstavlja i jedan od najugroženijih morskih okoliša.
U našem dijelu svijeta, koji zovemo zapadnim i smatramo razvijenim, prije samo 50 godina nisu sve žene imale pravo glasa na izborima, nisu imale jednak pristup obrazovanju, nisu mogle voditi države i nisu imale pristup visokim pozicijama u poslovnom svijetu.
Gotovo svi su upoznati s činjenicom kako oceani i mora prekrivaju više od 70 % površine Zemlje. Me?‘utim, nedovoljno je prepoznato kako su oceani, mora i obalna područja esencijalni dio Zemljinih ekosustava te kako o njima ovisi cijelo čovječanstvo, bilo na obali ili u dubokoj unutrašnjosti kontinenata! Zašto?
Ovaj cilj održivog razvoja odnosi se na ostvarivanje održive proizvodnje i potrošnje u čemu trenutačno ne uspijevamo jer je ekološki otisak koji ostavljamo i dalje ve?‡i od resursa koje imamo na raspolaganju. Dakle, potrebno je promijeniti načine na koji proizvodimo hranu, smanjiti bacanje hrane, pove?‡ati udjele obnovljive izvore energije u ukupnoj proizvodnji energije, pravilno gospodariti otpadom tijekom čitavog njegovog životnog ciklusa kako bi, me?‘u ostalim što manje utjecali na zaga?‘enje zraka, vode i tla.
Razvoj industrije i infrastrukture kao temelja za pove?‡anje životnog standarda za sve ljude, uz okolišno prihvatljiva rješenja te uključivanje novih tehnologija tema je cilja održivog razvoja koji se odnosi na okolišno prihvatljivu industrijalizaciju, kvalitetnu, pouzdanu, održivu i prilagodljivu infrastrukturu, a sve uz primjenu novih tehnologija, istraživanja i inovacija.
