They can be. But most are lower concentration and work by supporting microbial action which aids in carbohydrate exchange instead of heavy loading of nitrogen, phosphorus and potassium. Depends on a what they are using and how much. In poor soils in harsh growing environments organics alone aren't always sufficient or heavy applications of high urea content are required (not great for the waterways, to be sure). Ideally, you need to manage your soil carefully over a prolonged period - and even, then, it's not always possible if the environment is inhospitable. Like most things, the truth is complicated.

Eating doesn't give you energy right away, in most cases, and overeating often has energy that doesn't convert quickly.

Potato chips, meat, bread, rice, etc, are calorie dense, but full of complex carbohydrates and fats that need to be broken down into more simple sugars.

That process actually uses energy in the short term, before giving you a boost of energy later.

Simple sugars, like those found in juices and desserts, don't need to be broken down, and provide energy very quickly to the body.

So, what happens when you overeat? Your body shuts down to process the food, then has nowhere to go with the excess energy. That energy is then converted into fats and stored in the body for later.

Nutrient clean up is incredibly hard. The life in the water uses the nutrients quickly and exponentially multiply. Watershed restoration can help reduce impacts by increasing wetland and stream health and allowing these ecosystems to take up more nutirents before they enter the lake or ocean. These strategies can take a few years to fully reestablish and must be protected and maintained from invasive species or erosion removing the vegetated portions.

Do note. The guy seems to be talking about simple odds using real plane crashes for some reason.
Real world statistics do not work that way.

In the real world plane crashes are not independent events.
In the real world you knowledge of the odds of plane crashes is not complete.
A plane crash will cause the ground crew and flight crew to change their behavior, shifting the odds.
A plane crash is evidence that your assumptions on the safety of a given model of plane might be incorrect.

In the magical world of simple odds, safety audits and groundings wouldn't make a lick of sense. They do in the real world.

Likewise the forced induction engine really gets its fuel economy from being smaller than the naturally aspirated counterpart per horsepower. Forced induction engines require lower compression ratios which results in reduced efficiency per horsepower, but less weight still means less power.

The waterways get "algae blooms" where all the extra nutrients from the fertilizer helps algae grow rapidly. However, this algae all dies fairly quickly and becomes food for a lot of microbes which breath oxygen just like us, releasing carbon dioxide. So those herbivores/decomposers end up using all the oxygen and the fish die as a result. So it's not the plants/algae that deplete the oxygen, it's the herbivores and decomposers that can grow rapidly from having a huge food supply.

Humans had a lunar calendar of 13 months, 28 days, that would have been known soon after modern humans showed up, maybe 80-100K years ago. You need to know if you have 1 month, or 10 before the next snow comes.

That would have nothing to do with orbital mechanics or anything, even if you think apollo is riding thru the sky on his chariot, he's doing it in a predictable pattern, and recognizing patterns is basically a super power for humans, it wouldnt take long for them to keep track of it.
