    Important note, if you take a straw that separates into two split straws (kinda in a “Y” shape) that from a topological point of view is two holes, because one is for one of these paths, and the other is an extruded hole on the side of the first path. In topology you can’t break or mend material, but you can pull, stretch, squeeze and move it all you want. So you can move one of the split straw “legs” to the bottom of the whole straw, getting a shape similar to a “V”, it would look pretty much like a pair of pants. And topologically speaking it would be exactly the same. So… One straight hole for your mouth all the way down to your anus. Another two are there for your nostrils, that’s 3 already. The rest are for your tear ducts, which have two holes on the edge of your eye, (so four in total) which merge and then connect to your nose.

    So a human, from a topological perspective, is just a seven holed doughnut. Also Vsauce made a great video about that, with pretty great animations.


  • No benefit? No, of course not. But for more money to the shareholders of the oil and coal companies which some politicians either are or get payed by. OF COURSE! They will do it gladly with a smile.

    Renewables aren’t funded anything close to what governments of any country spend on oil and coal companies, and that’s for the benefit of the very few people who own them.

    Didn’t we already figure out the whole climate change story way back long ago? And the only reason why we didn’t do anything about it were studies funded by the oil industry so that they absolutely have to show there was “no link” between our CO2 emissions and the global temperature? Because I’m pretty sure that’s the story.









  • I don’t know. There’s a lot of plastic in the ocean, and as far as I know there are ways for it to go back into the rest of the ecosystem like water does, so plants will probably gather it as well. Less than animals but still some.

    Regardless of whether you eat meat or not, you will get some of it in your system. Whether that’s bad, and how much of it could cause issues is still unknown. From what I know there aren’t any studies that state what effect microplastics have on our bodies. Probably because you would need a significant amount of people without any in their bodies as a base group, and with how much plastic is used by us every day that would be difficult to find.

    Although, eating less meat is generally healthier, better for the ecosystem and cheaper (especially if you grow stuff, even in small pots near a window) so if you can switch to vegan/vegetarian diet without any health problems, you should give it a try but be mindful of your diatery needs, it’s easy to not get enough vitamins or proteins if you don’t plan your meals well which could lead to anaemia. Even if it doesn’t work for you, at least you will know more recipes.

    Also, I’m not a scientist, biologist or anyone with any credibility in this field, I’m a software developer and my biology is on high school level, so take everything I said here with a grain of salt since I may be wrong.
