This from world economic forum in 2019 - Here’s how we can use agriculture to fight climate change suggests a starting place for reading.

Another large scale kind of project we have data for is when we have made things like dams for power or flood control. The lakes created have big effects on climate.

This resource - takes the position that hydro dams are to be avoided (which I disagree with) but also raises questions that every project should consider. Someone at National Geographic also has the opinion that dams are bad but again it seems to me that dams give us another lever to adjust to reduce problems like flooding / agricultural water use / drought.

After some research, I think it's very likely that kid had diabetes (though they probably didn't know it at the time). Eating a ton of raisins means eating a ton of sugar, and that will seriously fuck up a diabetic kid.

I found some indication that eating a ton of raisins can increase your chances of a stroke, but the link seems tenuous and I can't find any dosage information.

Not to suggest you should fill up on raisins if you're not diabetic, not doing that is very good advice regardless of why that kid died.

We called them “witching sticks” too. And yes they work. If the hands of a skilled person they would lead the user to land that was disturbed or not solid- usually because of water. I have a dear friend who has taught people how to use them. It’s awesome to watch.

For psychology purposes, a topic's salience is how much of one's attention it gets.

You've surely met someone who can't seem to shut up about a certain topic. Maybe it's a ten-year-old who just LOVES Pokémon, maybe it's a grown man who's idolized some populist politician. Every conversation with this person somehow gets redirected to the thing they want to talk about, and it's always the same thing. That topic has a high salience for that person. Psychologists will be on the lookout for people who can't seem to give the proper amount of attention to other topics or activities, such as their family or personal hygiene, which is a bright line between "oh lawd, he on THAT again..." and "cray-cray harmful behavior."

When your body releases energy from food, chemically, it is the same process as if you lit that food on fire. The sugars, fats, and proteins are broken down into simpler molecules like water and carbon dioxide. Instead of releasing that energy as hear and light, our cells store it in chemicals to be used later. The amount of energy stored in food is measured in calories. Your body is always burning calories, and everyone has a baseline of how many calories they need daily just to stay alive. If you do nothing and eat more calories than your base line, you will put on weight. If you consume fewer calories you will lose weight. Alternatively, you can increase your activity while keeping your consumption constant which will lead you to burn more calories than you consume and cause you to lose weight

Weight loss happens when you burn more calories than you consume. It's not any more complicated than that. If you burn 2000 calories a day but only consumed 1800, you will lose weight. You burn a substantial number of calories (anywhere between 1000-2000 depending on age, weight, gender, physical condition, and other factors) just by being alive. In other words, you burn over 1000 calories a day just by laying in bed. digesting the food you eat also takes calories, and of course physical activity burns calories.

So to add that all up, let's say your basal metabolic rate is 1500 (these are the calories you burn just by being alive). Then let's say you burn 200 calories from digesting the food you ate throughout the day. Finally, you burn another 200 calories just from your physical movement throughout the day (walking around, doing the dishes...etc). That's a total of 1900 calories you burned in 1 day. If you ate less than 1900 calories that day, you will lose weight. If you ate more than 1900, you will gain weight.

Boiled potatoes are very interesting. They contain a lot of starch, but when a boiled potato cools down (i.e. on your plate) then the starch in the potato turns into something called 'resistance starch'.

Resistance starch stays intact more until the intestines where it acts as a fibre for intestinal flora. Cooled rice also has this affect too. I think this sense of the starch keeping form for longer is what's ultimately responsible for the difference. Fibre and starch and proteins keep their forms longer which contribute to a feeling of fullness. Focusing on calories alone doesn't work for example, you can consume a lot of calories in sugary alcohol and not feel full compared to the same calories in food. This is because the drink is more fluid (less fullness) and the calories are absorbed significantly quicker and earlier in the digestive tract.

As others have pointed out, water content, portioning size (small individual chips vs bigger potatoes) also come into it.

Salience basically means "stand out-iness". E.g. a salient issue is an issue that stands out as important. In addiction, it refers to how the thing you're addicted to is constantly at the top of your mind.

This paper describes it well:

> This refers to when the particular activity becomes the most important activity in the person’s life and dominates their thinking (preoccupations and cognitive distortions), feelings (cravings) and behaviour (deterioration of socialized behaviour). For instance, even if the person is not actually engaged in the behaviour they will be thinking about the next time they will be.
