Seriously folks, are you listening to what they are blatantly declaring?? Do you think they are kidding? I cannot believe they can state their justification for what they are doing with a straight face.
You better believe that these people are SERIOUS about the Objectives. Their completion date is just around the corner. You should be able to tell by the graphic below that they have taken all factors into consideration and are convinced that they have everything in place to accomplish their goals. SOURCE

Now scientists say BREATHING is bad for the environment: Gases we exhale contribute to 0.1% of the UK’s greenhouse gas emissions
- Two greenhouse gases – both more potent than CO2 – are in human breath
- One is methane which is famously also emitted from livestock such as cows
Whether it’s eating less meat or cycling instead of driving, humans can do many things to help prevent climate change.
Unfortunately, breathing less isn’t one of them.
That might be a problem, as a new study claims the gases in air exhaled from human lungs is fueling global warming.
Methane and nitrous oxide in the air we exhale makes up to 0.1 per cent of the UK’s greenhouse gas emissions, scientists say.
And that’s not even accounting for the gas we release from burps and farts, or emissions that come from our skin without us noticing.

The new study was led by Dr Nicholas Cowan, an atmospheric physicist at the UK Centre for Ecology and Hydrology in Edinburgh.
‘Exhaled human breath can contain small, elevated concentrations of methane (CH4) and nitrous oxide (N2O), both of which contribute to global warming,’ Dr Cowan and colleagues say.
‘We would urge caution in the assumption that emissions from humans are negligible.’
As most of us remember from science classes at school, humans breathe in oxygen and breathe out carbon dioxide.
When we inhale, air enters the lungs, and oxygen from that air moves to the blood, while carbon dioxide (CO2), a waste gas, moves from the blood to the lungs and is breathed out.
With plants, it is the other way round; plants use CO2 to create oxygen as a by-product (the process known as photosynthesis).
Every person breathes out CO2 when they exhale, but in their new study, the researchers focused on methane and nitrous oxide.
These two are both powerful greenhouse gases, but because they’re breathed out in much smaller quantities, their contribution to global warming may have been overlooked.

What’s more, plants essentially soak up all the CO2 that’s emitted in human breath, so ‘CO2 contribution in human breath to climate change is essentially zero,’ Dr Cowan told MailOnline.
The same cannot be said for methane and nitrous oxide, as plants don’t use these gases in photosynthesis.
For the study, the researchers investigated emissions of methane and nitrous oxide in human breath from 104 adult volunteers from the UK population.
Participants were required to take in a deep breath and hold it for five seconds, then exhale into a sealable plastic bag.
A total of 328 breath samples were collected and every participant had details recorded such as age, sex and dietary preference.
After analysing the samples, researchers found nitrous oxide was emitted by every participant, but methane was found in the breath of only 31 per cent of participants.
Researchers say those who do not exhale methane in their breath are still likely to ‘release the gas in flatus’ – in other words, by farting.
Interestingly, people with methane in their exhaled breath were more likely to be female and above the age of 30, but researchers aren’t sure why.
Concentrations of the two gases in the overall samples let the researchers estimate the proportion of the UK’s emissions are from our breath – 0.05 per cent for methane and 0.1 per cent for nitrous oxide.
Dr Cowan stresses that each of these percentages relate specifically to these respective gases, not all of the UK’s greenhouse gas emissions as a whole.
Researchers didn’t manage to find any link between gases in the breath and diets – although meat eaters are known to fuel the climate crisis in other ways.
The experts stress that their study only looked at greenhouse gases in breath, and so it does not provide an overall estimate of a person’s emissions footprint.
In experiments, all participants breathed out carbon dioxide (left). Nitrous oxide (right) was also emitted by every participant, but methane (centre) was found in the breath of only 31 per cent of participants
According to the authors, emissions of methane and nitrous oxide are ‘generally ignored in most environmental monitoring’ as they’re considered negligible.
However, further study of human emissions of these gases – not just from our breath – could reveal more about ‘the impacts of an ageing population and shifting diets,’ the team say.
Inside the human body, methane gas is produced by microorganisms called methanogens, which colonise our digestive tract.
The methane crosses into the blood and is carried to the lungs where it can be exhaled in breath.
Meanwhile, bacteria in the gut and oral cavity turns nitrates in food and water to nitrous oxide, which also escapes in human breath.
The study has been published in the journal PLOS One.

Think about what life without chickens or egs would be like. Eggs are required in so many recipes, besides being quite delicious on their own in so many forms. Chicken like wise provides so many options.
A no-beef diet is great — but only if you don’t replace it with chicken
Let’s not swap one moral disaster for another.
Most people have heard it by now: Our meat habit is bad for the world. Polling suggests that tens of millions of people are taking this message seriously: One in four Americans said they tried to cut back on meat in the last year, and half of those cited environmental concerns as a major reason. The popular food site Epicurious recently announced they’ve stopped publishing recipes with beef in them, because of beef’s climate impacts, setting off the latest round of discussion on meat’s effects on the environment.
Cutting meat consumption is as smart an idea as advertised. Industrial farming — the source of 99 percent of the meat Americans eat — provides the world with cheap meat, but it does so at a terrible environmental and moral cost.
Where it gets complicated is when people decide which meat, exactly, they’ll be cutting back on. Often, it’s beef that loses out in that calculus. And often, the messaging is that we can save the world by switching out our beef consumption for chicken.
The problem with this message is that switching beef for chicken basically amounts to trading one moral catastrophe for another.
The environmental reasons for cutting beef from one’s diet are clear. Most of the climate impact of animal agriculture comes from raising cows for beef. Cows produce methane, a greenhouse gas that is a major contributor to global warming; it’s much more potent than carbon dioxide. Transitioning away from eating beef to eating other factory-farmed animal products undoubtedly reduces the carbon impact of a person’s diet.
But the transition away from beef can end up being a Pyrrhic victory if it drives up the world’s rapidly rising chicken consumption. That ends up swapping one disaster — the climate crisis and beef farming’s role in it — for another: the moral disaster of industrial chicken production.
To put it simply, it takes many, many more chicken lives than cow lives to feed people. Cows are big, so raising one produces about 500 pounds of beef — and at the rate at which the average American eats beef, it takes about 8.5 years for one person to eat one cow. But chickens are much smaller, producing only a few pounds of meat per bird, with the average American eating about one whole chicken every two weeks. To put it another way, each year we eat about 23 chickens and just over one-tenth of one cow (and about a third of one pig).
Giving consumers better choices
Consumers who are reconsidering their meat consumption — for the sake of animals, the planet, or both — are doing a courageous thing, and the point of observing the added complications of this choice isn’t to discourage them. Fixing our broken food system is going to require substantial policy and corporate changes, as well as consumers making better choices. The beef versus chicken conversation is part of how we get there.
But what the dilemma lays bare is that there’s no meat consumption that will save the world. Meat is one of the most popular foods, and yet building a better world is going to require inducing consumers to switch away from it — and not just switch between different categories of meat as they weigh the different environmental and moral catastrophes it causes.
That’s why some animal advocates in the last few years have switched from convincing consumers to go vegan — which can be too big of a leap for many — to advocating for plant-based meat products. These plant-based products are already difficult to distinguish from the originals, while having a lighter carbon footprint and no impact on animals. If you avoid beef by switching to plant-based meat products, you really are improving the world and improving conditions for the humans and animals that live on it.
But despite all these complications, when prominent food sites take beef out of their lineup or when Americans tell pollsters they’re trying to cut back on beef, it’s cause for optimism — even though in the short term, depending what they replace it with, it could make things worse. Our food system delivers meat cheaply at an awful price. Starting more conversations about that price and how we can mitigate it is a good thing, even if it’s a conversation a long way from a satisfying resolution.
