Wildlife in ‘catastrophic decline’ due to human destruction, scientists warn
50% of habitable land on earth is taken up by agriculture, 77% of which is used for meat &amp; diary (including the crops grown for livestock to eat), which contributes only 18% to the global calorie supply because of the inefficiency of animal products:<p><a href="https:&#x2F;&#x2F;ourworldindata.org&#x2F;agricultural-land-by-global-diets" rel="nofollow">https:&#x2F;&#x2F;ourworldindata.org&#x2F;agricultural-land-by-global-diets</a><p>I wonder how much of an impact it would have to return the land used by meat &amp; diary to nature (40 million km^2 out of the 104 million km^2 of habitable land, minus some for more crops for humans). Wild animals would have more of chance, they&#x27;d be more forests to capture more carbon, and industrial animal farming wouldn&#x27;t be polluting the planet with carbon, methane and waste products that are contributing to climate change.<p>I don&#x27;t know a practical solution to the above, but people are in denial about how much damage animal farming is doing globally and the insane scale of it (about 70 billion animals are used for food each year).<p>The general attitudes of &quot;well, people are never going to reduce their use of animal products to help so...&quot; and &quot;lab based meat will save us at some point in the future and then I&#x27;ll probably switch if they&#x27;re indistinguible from real meat&quot; is depressing. We&#x27;re running out of time.
