Wildlife In 'Catastrophic Decline' Due To Human Destruction, Scientists Warn (bbc.com) 114

Posted by BeauHD from the we-are-to-blame dept.
An anonymous reader quotes a report from the BBC: Wildlife populations have fallen by more than two-thirds in less than 50 years, according to a major report (PDF) by the conservation group WWF. The report says this "catastrophic decline" shows no sign of slowing. And it warns that nature is being destroyed by humans at a rate never seen before. The report looked at thousands of different wildlife species monitored by conservation scientists in habitats across the world. They recorded an average 68% fall in more than 20,000 populations of mammals, birds, amphibians, reptiles and fish since 1970.

Measuring the variety of all life on Earth is complex, with a number of different measures. Taken together, they provide evidence that biodiversity is being destroyed at a rate unprecedented in human history. This particular report uses an index of whether populations of wildlife are going up or down. It does not tell us the number of species lost, or extinctions. The largest declines are in tropical areas. The drop of 94% for Latin America and the Caribbean is the largest anywhere in the world, driven by a cocktail of threats to reptiles, amphibians and birds. Research published in the journal Nature suggests that to turn the tide we must transform the way we produce and consume food, including reducing food waste and eating food with a lower environmental impact.

    This kinda reminds me of a short film, Michael Moore presents Planet of the Humans. It's mostly by a guy who has worked with Moore for many years, Jeff Gibbs.

    Despite the fact that Moore can sometimes be a lying sack of shit, this week one is actually pretty good, and shows what might be the only way we can save the planet that can actually work.

    https://youtu.be/Zk11vI-7czE [youtu.be]

    For any film with Moore's name on it, don't go quoting anything you see as fact because he has been known to stretch the truth on particular details, but the overall film is insightful.

    • Not famiiar with M. Moore's films, but do you have any links to credible studies or sources to the claims that his films canot be trusted? Legitimately curious and interested to sÃe the whole picture and/or debate.

      • I don't think he lies but he cherry-picks the data.

      • Normally I'd cite authoritative sources and all, but this morning I'm kinda busy, so here is one article that seems to do a decent job of covering one of this films, as an example:

        https://whatculture.com/film/5... [whatculture.com]

        I'm sure there are more rigorous treatments around if you Google for them, but that's a start to get the idea.

        Impossible burger is ridiculously processed to the point where a lot of experts saying it's not healthy. For a reliable source of non-animal protein, go with the proven things: beans and nuts.

        Also, don't get hung up on all-or-nothing propositions. A 4 oz. burger can be quite tasty. If you were eating 8 oz. burgers every day, and you go to 4 oz burgers every other day, Bam! You just cut your beef consumption 75%, and you'll be a lot healthier.

          The population will have tripled by the time you convince everybody of that.

Bats in China; cutting shark fins off and leaving sharks to die (or kill shark but only retain fins, plus the spine) also by and for the Chinese; hunting whales by Japan (science, yummy!). Therefore, controls on population size is key. Anything that ignores it is not realistic.

        • Or you could just eat a 4 oz. impossible burger... It's true that they don't appear to be much healthier than beef, but there haven't been many claims saying that they're worse.

      Most people do not chose to have kids, it's an instinct, a urge encoded deeply within the genes. You have to have kids because it's the sole purpose of life, the sole existence of your genes is to reproduce themselves. Then, you can find other bullshit explanation like "it's the greatest joy of your life", but the main reason is still an unexplainable urge.

      And since it's impulse over logic, the growing population is very likely to be an ecological catastrophe. People keep following their reproductive instin

      • Most people do not chose to have kids,

        Most pregnancies carried to term are voluntary, even though most pregnancies are unplanned. Almost all people have access to birth control, and most people have access to abortion. So most people definitely choose to have kids.

    • If all people that understand that don't have kids, only people that don't understand it will have kids. You're only making matters worse by not having kids. Idiocracy starts with you.

    No behavior and no veganism will prevent the apocalypse, if we're more than 100 billion people! It is impossible to sustain the planet with infinite growth. Any child trying to stuff more and more candy into its mouth understands that.

    And if you actually want to do something ... don't become vegan or something, like a slacktivist ... but: Have only one child! (And to avoid developmental problems, make sure it has other children to play with every day and every hour, form the first day it is born.)
    We shoud reward that.

Make sure everyone is well off. ... Redistribute that wealth a bit without taking anything from anyone: Support automation that is owned by the people, so the resulting wealth is too. [That's how you get a Star Trek society] ... Reduce overpopulation as a result ... Save the planet due to it ... Tadaa: Humanity can be sustainable ... in its continued survival.)
