Advantages and Disadvantages of Agriculture

‘All right, […] let’s take a look at the advantages and disadvantages of agriculture.

Advantage: Controllable food supply. You might have droughts or floods, but if you’re growing the crops and breeding them to be hardier, you have a better chance of not starving.

Disadvantage: In order to keep feeding people as the population grows you have to radically change the environment of the planet.

Advantage: Especially if you grow grain, you can create a food surplus, which makes cities possible and also the specialization of labour. Like, in the days before agriculture, everybody’s job was foraging, and it took about a thousand calories of work to create a thousand calories of food, and it was impossible to create large population centres.

But, if you have a surplus, agriculture can support people not directly involved in the production of food. Like, for instance, tradespeople, who can devote their lives to better farming equipment, which in turn makes it easier to produce more food more efficiently, which in time makes it possible for a corporation to turn a profit on this ninety-nine cent double cheeseburger. […]

Some would say that large and complex agricultural communities that can support cities and eventually inexpensive meat sandwiches are not necessarily beneficial to the planet or even to its human inhabitants. […]

Advantage: Agriculture can be practised all over the world, although in some cases it takes extensive manipulation of the environment, […] irrigation, controlled flooding, terracing, that kind of thing.

Disadvantage: Farming is hard. So hard, in fact, that one is tempted to claim ownership over other humans and then have them till the land on your behalf, which is the kind of non-ideal social order that tends to be associated with agricultural communities.’

The universe is shaped like a vuvuzela.

The Queen of England is the legal owner of one-sixth of the Earth’s land surface.

The average Japanese watches an average of 4 hours and 29 minutes of television every day – the highest in the world. Americans are ranked second – 4 hours and 25 minutes.

Everybody expected the Spanish inquisition – they were legally obliged to give 30 days’ notice.

About 3000 people so far have reached the top of the 29,035 ft. peak of Mount Everest. Those people and others who attempted the ascent left over 100 tons of trash. There are about 120 corpses left on the mountain. The rate of success is about one death for every 10 successful ascents.

Nyctinasty and Thigmonasty

Nyctinasty is a nastic movement (a non-directional responses to stimuli; for instance, temperature or humidity) that is associated with diurnal changes of temperature or light intensity.

Thigmonasty, also known as seismonasty, is a nastic movement in response to shock, especially the rapid folding of the leaflets of the sensitive plant due to changes in turgor pressure (cells distended beyond the natural state by some internal agent, especially fluid, or expansive force) caused by vibration.

Carbon Footprint‏

Carbon footprints measure how much carbon dioxide (CO2) we produce just by going about our daily lives. It is the measure of the environmental impact of a particular individual or organization’s lifestyle or operation, measured in units of carbon dioxide.

“Dealing with global warming doesn’t mean we have all got to suddenly stop breathing.” – David Attenborough

A carbon footprint is composed of two parts, a primary and secondary footprint. When fossil fuels burn, they emit greenhouse gases like CO2 that contribute to global warming – this is the primary footprint. Ninety-eight percent of atmospheric CO2 comes from the combustion of fossil fuels. The secondary footprint is the sum of indirect emissions associated with the manufacture and breakdown of all products, services and food an individual or business consumes.

“I would remind you to notice where the claim of consensus is invoked. Consensus is invoked only in situations where the science is not solid enough. Nobody says the consensus of scientists agrees that E=mc2. Nobody says the consensus is that the sun is 93 million miles away. It would never occur to anyone to speak that way.” – Michael Crichton
