Ecology and  How to slove global warming  - Page 3 Empty Flying cars and climate change

Have you ever been stuck in traffic and wished you could zoom above the gridlock in a flying car? A new study predicts these futuristic vehicles could be good for your commute and good for the environment — as long as they’re used on long-distance trips with several carpool buddies.

Yes, it is true that flying cars would be more sustainable if used as ride-share taxi services!

Ecology and  How to slove global warming  - Page 3 Empty Are flying cars ecological ?

Message  MurielB Lun 5 Aoû - 15:52

http://en.rfi.fr/france/20190805-frenchman-franky-zapata-hopes-unveil-flying-car-year-s-end

Flying Frenchman Franky Zapata who jet-powered  his hoverboard across the English Channel on Sunday intends to unveil a flying car by the end of the year.


The 10-turbine flying car that would be easy enough for anyone to pilot, without requiring the physical strength and long hours of practice to master the Flyboard, Zapata believes.

"We expect to have the authorisations for test flights in the coming days," he said, adding that it would initially have a range of 100-120 kilometres.
“We're going to take a bit of holiday... and then the whole team will get back to work so it's ready”
Zapata worked on his hoverboard for the past three years, despite losing parts of two fingers during its maiden flight in his garage near Marseille, when they got sucked into the turbines.

Message  MurielB Lun 5 Aoû - 16:54

The device has an autonomy of about ten minutes. The Channel crossing therefore requires refuelling with kerosene - which Zapata stores in his backpack - along the way, by landing on a boat. I wonder if his flying car project will be an ecological one - that is 0 percent of emission on use ?

Ecology and  How to slove global warming  - Page 3 Vegan_10
Interest in vegan food has been booming across the rich world. Celebrity claims of veganism are everywhere: Bill Clinton and Al Gore, Serena and Venus Williams, Lewis Hamilton, Mike Tyson, Beyoncé, take your pick. In America sales of “plant-based” foods—a term for foods that contain no meat, eggs or dairy that reliably says “vegan” to vegans but doesn’t say “weird” to the less committed—rose 20% in the year to June 2018, according to Nielsen, a market-research group
People are vegan to prevent animal suffering, for their own health (Eating red meat is not good) and for the environment.
This awareness is interesting and important. Each person can thus take part in the improvement of the world

https://www.theguardian.com/environment/2018/nov/13/the-plastic-backlash-whats-behind-our-sudden-rage-and-will-it-make-a-difference
Plastic is everywhere, and suddenly we have decided that is a very bad thing. Until recently, plastic enjoyed a sort of anonymity in ubiquity: we were so thoroughly surrounded that we hardly noticed it. You might be surprised to learn, for instance, that today’s cars and planes are, by volume, about 50% plastic. More clothing is made out of polyester and nylon, both plastics, than cotton or wool. Plastic is also used in minute quantities as an adhesive to seal the vast majority of the 60bn teabags used in Britain each year.

Add this to the more obvious expanse of toys, household bric-a-brac and consumer packaging, and the extent of plastic’s empire becomes clear. It is the colourful yet banal background material of modern life. Each year, the world produces around 340m tonnes of the stuff, enough to fill every skyscraper in New York City. Humankind has produced unfathomable quantities of plastic for decades, first passing the 100m tonne mark in the early 1990s. But for some reason it is only very recently that people have really begun to care.
Yes genetically modified algae will be very useful. We used to see plastic as litter that is a nuisance but no a menace.  To-day Plastics pollution has a direct and deadly effect on wildlife especially in oceans and seas. Thousands of seabirds and sea turtles, seals and other marine mammals are killed each year after ingesting plastic or getting entangled in it.

Ecology and  How to slove global warming  - Page 3 Empty Bees declared the most important living creatures on earth

Message  MurielB Sam 12 Oct - 17:58

The Earth Watch Institute has declared the #bees as the most valuable species in the world in the last debate of the Royal Geographical Society of London.
Ecology and  How to slove global warming  - Page 3 Image

The direct benefits that for life and #Saludhumana represent the products made by bees are secret to anyone. But the reality is that we should not stop just thinking about the benefits it brings to our health but assess its most extensive function in the natural chain that is pollination without which life on the planet would definitely be impossible. The bee is the only insect that provides food to humans.
The #biodiversity is the process of interaction between living beings and the planet, the relationship between them, and of course, the biological response of the environment to the species.
In this process the bee has a vital function since the world agriculture depends on 70% of these insects, said more clearly 70 of every 100 products that we use to feed depend exclusively on the bees. The balance is self-explanatory: Without pollination plants could not reproduce and without plants the fauna would also disappear and consequently, humans.

Hi everyone
While the negotiations about political ecology projets are not successful, the coronavirus has drastically reduced the emission of greenhouse gases in China.
Saving the planet is therefore possible because when there is a will there is a way !

Ecology and  How to slove global warming  - Page 3 Empty The ‘herd immunity’ route to fighting coronavirus is unethical and potentially dangerous

Message  MurielB Jeu 19 Mar - 22:34

As most of the world tries to suppress the coronavirus spread, some countries are going it alone - trying to manage the pandemic through so-called “herd immunity”.

Herd immunity means letting a large number of people catch a disease, and hence develop immunity to it, to stop the virus spreading.

https://theconversation.com/the-herd-immunity-route-to-fighting-coronavirus-is-unethical-and-potentially-dangerous-133765
 Hi everyone
Some countries do not choose containment and  let the population expose itself to the virus by invoking the phenomenon of herd immunity. This decision is hardly acceptable as the coronavirus has already killed more than 8,000 people worldwide. The solution of letting the population expose itself to the virus is favourable to the economy but is not ethically acceptable.

Ecology and  How to slove global warming  - Page 3 Empty Generation Anthropocene: How humans have altered the planet for ever

Message  MurielB Dim 28 Juin - 18:34

https://www.theguardian.com/books/2016/apr/01/generation-anthropocene-altered-planet-for-ever
n 2003 the Australian philosopher Glenn Albrecht coined the term solastalgia to mean a “form of psychic or existential distress caused by environmental change”. Albrecht was studying the effects of long-term drought and large-scale mining activity on communities in New South Wales, when he realised that no word existed to describe the unhappiness of people whose landscapes were being transformed about them by forces beyond their control. He proposed his new term to describe this distinctive kind of homesickness.
Glenn Alrecht defines "solastalgia" as the pain or distress caused by environmental change  because it is changing in ways we perceive negatively. . It is the existential and lived experience of a negative environmental change, felt as an aggression against our sense of belonging to a place.

Ecology and  How to slove global warming  - Page 3 Empty How clean energy will remake geopolitics

Message  MurielB Dim 20 Sep - 11:01

https://www.economist.com/leaders/2020/09/17/is-it-the-end-of-the-oil-age
Oil fuelled the 20th century—its cars, its wars, its economy and its geopolitics. Now the world is in the midst of an energy shock that is speeding up the shift to a new order. As covid-19 struck the global economy earlier this year, demand for oil dropped by more than a fifth and prices collapsed. Since then there has been a jittery recovery, but a return to the old world is unlikely. Fossil-fuel producers are being forced to confront their vulnerabilities. ExxonMobil has been ejected from the Dow Jones Industrial Average, having been a member since 1928. Petrostates such as Saudi Arabia need an oil price of $70-80 a barrel to balance their budgets.  . Today it is scraping along at just $40
Hi everyone
Renewable energy is the engine of the 21st century, says The Economists  on the front page of its September 17 edition, playing on the double meaning of the word "power" - "force" and "electric current".

One plane rides on another’s wake
In order to migrate thousands of kilometres, the geese have adopted an inverted V formation. This system saves them a lot of effort.
Indeed, the wing beats of the leading bird's wings create whirlpools that make it easier for its escorts to penetrate the air. The European aircraft manufacturer has developed this technique to adapt it to commercial aircraft flights.

Ecology and  How to slove global warming  - Page 3 Empty How coronavirus will transform transport in Britain’s cities

Message  MurielB Lun 12 Oct - 22:15

https://www.google.fr/amp/s/amp.theguardian.com/environment/2020/may/18/a-new-normal-how-coronavirus-will-transform-transport-in-britains-cities
The coronavirus crisis means that packed public transport systems cannot run at full capacity. If people turn to private cars en masse it will lead to gridlock, economic meltdown as deliveries get snarled up and a rise in dangerous air pollution – the last thing needed in the midst of a respiratory disease pandemic.
“The only way London is going to operate in terms of our capacity on our roads and capacity on our public transport is to move wherever possible to cycling and walking,” said Norman. “It is good for our health, it is good for our mental health and it is good for the environment.”
Hi everyone
The potential benefits of these changes are innumerable. Studies have shown that walking and cycling improve physical and mental health, build more resilient communities, significantly reduce air pollution and help to decarbonise the transport system.

3 Ways to Save the Earth (nature.org)
We don’t have to accept a fate of gloom and doom for the Earth. This is a hopeful wake-up call, but only if we act with great urgency.
     1 Produce more food and less land (without  excess fertilisers and chemical sprays)
     2 only take what the fish populations can tolerate now, so our oceans can be more abundant and healtheir in the future.
     3 We must reduce carbon emissions to, or below, levels agreed to in the Paris Climate Agreement to prevent catastrophic harm.

Message  MurielB Mer 1 Déc - 22:35

https://www.buzzfeednews.com/article/zahrahirji/global-warming-3-degrees-celsius-impact
The World Is On Track To Warm 3 Degrees Celsius This Century. Here’s What That Means.
There’s a very real chance the planet will warm up an average of 3 degrees Celsius (5.4 degrees Fahrenheit) this century — and that would be disastrous.

In such a brutally hot world, scientists agree, deadly heat waves, massive wildfires, and damaging downpours will come far more often and hit much harder than they do today. The ocean will be hotter too and more acidic, causing fish declines and likely the end of coral reefs. In fact, a quarter or so of the Earth’s species may go extinct in such conditions or be headed that way. Our coastlines would be reshaped, a consequence of sea levels rising foot after foot, century after century, drowning places like Charleston, South Carolina’s Market Street, downtown Providence, Rhode Island, and the Space Center in Houston.

All of this, as climate scientist Daniel Swain of the University of California, Los Angeles, put it, would be bad: “Bad for humans. Bad for ecosystems. Bad for the stability of the Earth systems that we humans depend on for everything.”

Experts can’t say exactly how likely this future is because that depends on what humankind does to mitigate the worsening climate crisis, especially over the coming decade. But for world leaders gathering this weekend in Glasgow for the 26th United Nations Climate Change Conference (COP26), this future may well become an inevitability if they don’t agree to more aggressive and immediate measures to limit greenhouse gas emissions.
Experts predict that in the case of a 3°C warming, the area of land devastated by fire each year would double in the Mediterranean and increase at least sixfold in the United States. We all hope that it is not too late and we hope that our politicians will stop taking a short-term view of what needs to be done

Message  MurielB Mer 5 Jan - 22:56

The effects of a warmer world are visible in animals’ bodies | The Economist
For humans, adapting to climate change will mostly be a matter of technology. More air conditioning, better-designed houses and bigger flood defences may help ameliorate the effects of a warmer world. Animals will have to rely on changing their bodies or their behaviour. In a paper published in Trends in Ecology & Evolution, a team led by Sara Ryding, a phd candidate at Deakin University, in Australia, shows that is already happening. Climate change is already altering the bodies of many animal species, giving them bigger beaks, limbs and ears.
In some species of Australian parrot, for instance, beak size has increased by between 4% and 10% since 1871
Nature does things well and many animals will adapt. However, if some will have this chance, others will not and will disappear.
