“Until the early 1990s, the Morro basin was a patchwork of water-absorbing forests and grasslands, but they are mostly gone, replaced by maize and soya beans.”
It may be a good move to cut down on cattle ranching worldwide (to prevent deforestation, to cut back on carbon and methane production, to limit the ongoing human health crisis caused by increasing meat consumption, to avoid further water pollution from farm runoff, to limit predator persecution, and to spare countless animals the endless cycle of slaughter), but an irony here is that soya beans, the hero of every vegan and vegetarian, come at a terrible price. Deforestation and clearing for cattle ranching has been replaced with deforestation in favour of this detrimental monoculture of soya bean farming.
If course, it is true that the humble soya bean is the new answer to reducing or cutting out meat consumption, but the majority of this soya and maize is being grown to become feed for the animal agriculture industry, something the attached article completely fails to mention. Animal agriculture is literally eating up our planet in countless ways.
Less than a third of Argentina’s rainforest remains. Losing that much established forest means losing deep networks of tree roots which naturally absorb large amounts of water from underground aquifers. The result is a huge new river appearing on land as has happened in Argentina. Why is this a surprise now? There are myriad experts in these fields worldwide who would have known this was a likely outcome as a result of mass deforestation. Why aren’t scientists involved in such massive economic and environmental processes and decisions?
Brazil has been in the grip of terrible deforestation for decades. With a changing climate, increased precipitation and otherwise poor substrate, deforestation in these countries inevitably means more landslides and more flooding, and perhaps more new rivers. We are drastically altering the landscape of the planet, destroying habitats and disrupting entire ecosystems.
Countless wildlife have lost their homes during this shift to soya bean plantations and deforestation, something that cannot ever be undone. When are governments of countries with such invaluable habitats going to quit putting profit before protecting and preserving their and the world’s most precious and vulnerable natural heritage? Rainforests are incredibly diverse, most are quite ancient, and they are so important to the world in terms of carbon sinks and wildlife biodiversity – they must be protected.
‘Extreme’ fossil fuel investments have surged under Donald Trump, report reveals
Following on from the last post with projections of 10cm sea level rise as glaciers melt, as a result of climate change, banks are responsible for much of our climate change by merrily investing in dirty fossil fuels despite knowing the impact and consequences. Is money really all that matters to these people? If your bank is one of them, dump them.
“RAN spokeswoman, Alison Kirsch, accused banks such as JPMorgan Chase of “moving backwards in lockstep with their wrongheaded political leaders”.
Today’s post is brought to you by, “What the hell are we doing?” And “Oh shit.”
“Warming since the late nineteenth century has led to a marked retreat of most of the world’s glaciers. Ben Marzeion at the University of Bremen in Germany and his colleagues simulated the long-term response of thousands of glaciers to recent and projected climate change. The researchers found that glaciers are already committed to enough shrinkage to raise global sea levels by about 10 centimetres, even if global temperatures do not rise any further for centuries.“
Turns out there aren’t plenty of fish in the sea.
Recent evidence suggests humans evolved their big brains not on a diet of red meat after all, but on a diet of fish. Yes, fish is a great source of protein for all animals. Yes, unaffected by microplastics, pollutants and heavy metals, fish is good for us, ‘us’ being the ever-increasing human population of 7.6 billion and rising (and let’s face it, fish is no longer safe to eat).
Plenty of marine conservation organisations, such as Sea Shepherd, have been saying for decades that while we allow industrial trawlers and fleets of thousands of unregulated fishing boats to ravage the oceans with trawler nets and insidious ghost nets, fish stocks will collapse and there will be devastating implications for all marine life and human populations that rely on fish as a source of protein. Even some marine conservation orgs hadn’t fully understood the role that overfishing plays in the decimation of the oceans – and its impact on local human populations – and are still not condemning overfishing or advising their relatively affluent members to cut out fish from their diets as an effective way of ending their contribution to the terrifying problem of global overfishing.
Anyone can stop contributing to ending overfishing by not eating fish, wherever you are in the world, and by writing to relevant businesses and governmental departments (and your MP), and by boycotting companies which contribute to global (and local) overfishing.
“Almost one-third of the fish and nearly half of the seal-faeces samples contained one to four plastic fibres and fragments. Among the most common was polyethylene, which is found in plastic bags and bottles.“
I am an Arctic researcher. Donald Trump is deleting my citations
I’m stunned by this article. First of all, I had no idea the previous Canadian government destroyed 100 years of Arctic climate data. Secondly, we joke about Trump’s corruption, greedy business mind and being bought off by the Russians and huge corporations (does he think money is all that there is?), and his utter stupidity when tweeting about climate (“It’s freezing where I am so there cannot be global warming”), but this is real. This is systematic, deliberate climate change denial on behalf of big oil and other huge corporations because…money.
How are we allowing this? How are people becoming so blindly led, so brainwashed, so indignant and angry at the wrong people, at each other, instead of at those who have the power to destroy anything they want and are doing so. These very people are our downfall – of everyone, planet-wide. They deny science and deny fact to protect profit and greed, at all of our expense and at the expense of our precious living planet.
“Dr. Josiah Zayner, a scientist, biohacker, and founder of the biotech company, The Odin, is a member of this futuristic group and the first person known to have edited his own DNA.”
This article clearly overstates the “results” of Zayner’s human experiments on himself for click-bait value, as the results are presently unknown.
After studying Genetics as part of my BSc. Zoology degree, we were asked to write an essay on the ethical implications of the new CRISPR-Cas9 gene editing tools (happily, I got a first class mark). Indeed CRISPR raises a host of ethical questions and considerations. CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) was discovered and developed by two scientists in separate universities from naturally occurring gene editing systems within bacteria. The scientists were Jennifer Doudna and Emmanuelle Charpentier. They saw the simple yet effective method by which bacteria’s immune defence systems literally cut out invading viruses using enzymes, including the Cas-9 enzyme. It cuts viral DNA when encountered and creates CRISPR arrays which allow the bacteria to ‘remember’ the virus. When encountering the virus again (or something similar) the bacteria then use RNA segments from these CRISPR arrays to target the viral DNA and cut it up, rendering it safe.
It is not dissimilar to mammalian immune systems, where proteins (immunoglobulins) are created in response to encountering antigens (foreign bodies), which can then be triggered if encountering the same (or similar) foreign bodies again. The CRISPR-Cas9 system can be likened to the cut, copy and paste tools in editing software – it is exactly what CRISPR does with genetic material. Scientists have worked out a way of utilising this system in the lab to edit genomes. It can cut out, put back and move genes around.
The downside? Research has some way to go before we fully understand what all of our genes do, and how they interact with each other. A gene in one location on a strand of DNA may interact with and affect a gene in another location far away on the same strand. We don’t yet understand all of the complex interactions between genes. We do know that there are usually many dormant genes within a genetic strand, remnants of the evolutionary past of an animal or plant. So if you cut out a gene, how might that affect other genes? If you put one in, will it trigger a dormant gene? In some cases, scientists know exactly how to trigger dormant genes.
It is somewhat reassuring to know that experimentation is primarily limited to somatic cells and that it is uncommon in most countries to carry out genome editing on germline or embryonic cells. There are countries which practice outside of any agreed ethical codes, or any rules are largely unenforceable, so that some scientists may already be carrying out genome editing experiments on embryos and germ cells. However, allowances have already been made for genome editing to be carried out on early embryos in the UK and other countries. What is truly terrifying is that all other animals are at the mercy of our whims in the world of genome editing experimentation.
It is clear that we are fairly radically playing with a puzzle without the benefit of the full picture to work with. Gene editing is still firmly in the experimental stages of its evolution, with some amazing results, and some truly horrifying results which the general public never see or hear about (think cloning labs – they exist and the success rate is very, very low).
This is the stuff of the future, of history, of nightmares and dreams…and of Marvel comic books. Bio hacking meet the world, a world full of unethical, immoral practices and people only too happy to abuse and destroy for short-sighted greed. What could go wrong? Zayner (and others) is literally opening Pandora’s box by making gene editing kits available to anyone who can afford the price of the kit. However, what’s in the box is incredible and has almost unlimited potential for a world where disease is non-existent, where some of the damage we’ve done can be rectified, and where humans might be altered in ways limited only by imagination.
Personally I’m still holding out for those wings, and an echolocation system.
I briefly researched acidification in a corals essays I wrote last year (for which I got a first class mark); this study looks in-depth at the impacts of acidification on marine life.
Ocean acidification is deadly threat to marine life, finds eight-year study
So I’m writing an essay about drivers of coral reef bleaching, and reading about acidification and its effects on marine mammals that secrete calcium carbonate, and this new research pops up. Interesting immediate adaptation to cope with lower pH levels in marine environments; although I’m not sure how long-term (and effective) an adaptation it might be. Similarly, some coral species and their symbionts are more tolerant of some drivers of bleaching than others. Again, in the short-term that helps those species, but it’s not clear how far beyond their normal thresholds for CO2, irradiance, thermal stress and acidification they can survive. And then there’s coral diseases… We are pushing the limits, changing environments and testing tolerance thresholds for so much of the world’s wildlife, and not in a good way.
