- Why are environmentalists against the Keystone Pipeline? That oil is going to be transported one way or another. Isn't using a pipeline cleaner and safer than using boats or trucks? | [
"Ish. The problem is the magnitude of the consequences of failure. Transport but truck (or rail) increases the odds of an environmental accident over a pipeline. However, if the pipeline fails, the scale of damage will be exponentially larger. First, there's detection. We have to know there is a failure (yes , ther... | [
"Well, since no one else is chiming in, I will start: Pro: Pipelines have fewer spills than trucks or trains. Pro: Pipeline spills tend to be out in the middle on nowhere instead of populated areas. Pro: This will improve the profit margin on oil that is already barely profitable. Pro: This is following the route o... | eli5_question_answer | {

Why do D-day Landing crafts open at the front? | [
"Because then they would be stepping out in to pretty deep water on the side. This is the answer but I need to pad it out so the auto-mod doesn't delete it. Direct answers are frowned upon here."

Why (in the US) did crime rise sharply throughout the 60s, 70s, and 80s, but fall from the mid-90s to the present? | [
"Nobody is entirely sure. This has been intensely studied, and some theories include atmospheric lead from gasoline and paint (leading more people to go a little nuts and commit crime until it was abated); legalized abortion leading to fewer children raised in unwanted homes (which could explain the fall but not th... | [
"In a lot of ways, trying to pigeon hole this is arbitrary and debatable. There is certainly nothing \"official.\" That said, you'd be safe ticking off a generation every 20 - 25 years or so.

/ Why do unused blades lose their sharp edges over time? | [
"The fine edge oxidizes. If you were to look at the very thinnest part of the blade under a microscope, you'd see pitting and etching from rust - even stainless steels are not immune. You can protect them to some degree by drying them thoroughly and then oiling them after use."

Instead of removing the testicles and ovaries and uterus, why do so many veterinarians not perform vasectomies and tubal ligations? | [
"It's not only about preventing pregnancy, it's also about behavioral control, cleanliness, cancer prevention, and infection prevention. If a female dog's ovaries and uterus were still intact, she would still have heat cycles--which means owners will be cleaning up blood. Then as she ages, her chances of eventuall... | [

Why do people smell different when they've been outside in the cold? | [
"because most of the things we smell are volatile substances (evaporate easily). however when these substances get cold they have more difficulty evaporating. so the person who has been in the cold made their jacket cold and so they stop emitting their normal smell. and any smells in the air condense on the jacke... | [

Why do cats not need to be taken on walks like dogs? | [
"For dogs, it's a migration instinct. In the wild, canine packs will go on walks led by the Alpha Dog (in this case, the dog's owner) in search of food. This is something that dogs have a fundamental, primal desire to do, and not doing it can cause a dog to become stressed and anxious (imagine a bird that's not bei... | [

how does Braille work for languages with complex writing systems like Chinese and Japanese? | [

"I'm 99% sure this has been answered. Incredibly, in a language like Japanese you type in an approximation of the phonetic equivalent in the roman alphabet.

Why do MLB players get paid absurdly more money than NFL athletes, a far more watched sport? | [
"There's a couple big reasons. First, the NFL has more players on the roster than MLB. The NBA has even fewer players, and on average, they make more than MLB players. Second, the NFL has taken a more egalitarian approach between its teams than the MLB. The NFL shares profits across teams to a greater degree than M... | [

Usage of jet engines vs turboprop | [
"Couple reasons, props have a lower efficiency compared to jets at higher speeds, and jets are more cost effective on aircraft that move faster (which large planes, like commercial airlines do).

"well the e-2c hawkeye is from the 1960s. so it's not exactly \"modern\". but this isn't a fighter aircraft, so it doesn't need to be fast. there's no need for a turbojet when the turboprop is still just fine. keepping the turboprop is cheaper and easier refitting on a turbojet."
