The man moves efficiently without the aid of any implements. Walking makes its way. The locomotion of each gram of its own body or its load, over each kilometer traveled in ten minutes, consumes 0.75 calories. Comparing it to a thermodynamic machine, man is more profitable than any motorized vehicle, which consumes at least 4 times more calories in the same path. It is more efficient than all animals of comparable weight. The shark or the dog wins, but only in a little. With this efficiency index of less than one calorie per gram, historically organized its circulation system, which is predominantly based on traffic *. Explored the world, created cultures, held shops, and, as far as we can know, spent only 3.5 percent of social time moving away from home or camp. Only a few peoples, at rare moments in their history, probably devoted more than this percentage of the common time in moving or dealing with their vehicles and animal engines, for example the Mongols in their wars.

> a century ago man invented a machine that gave him even greater efficiency: the bicycle. It was a novel invention, based on new materials, unthought in the time of the young marx and combined in an ingenious technology.

Harrell's | Disease of the Month: Rhizosphaera
Spores of this disease are spread via splashing water, overhead irrigation and extended wet periods to help spur the disease on. Like many other cold-weather diseases this pathogen is almost never noticed until it is too late to treat and save the plant.

Forests, Trees and AgroforestryWebinar: Gender, agroforestry and climate change in Latin America - Forests, Trees and Agroforestry
Has extensive work experience in research, development and environmental conservation projects in Latin America and Africa. There is also a wealth of local knowledge on the agroecological functions of these trees.

Who is Helena?
I have not gotten over Stephenie Meyers' penny yet; I keep having arcades whenever I see teen books. A Crépusculo without so much cursilería, with an argument and a protagonist thousand times better.

Using the bicycle makes it possible for the movement Of the human body frank out a last barrier. Allows you to take advantage of the available metabolic energy and accelerate the locomotion to its theoretical limit. On flat ground, the cyclist is three or four times faster than the pedestrian, spending in total five times less calories per kilometer than this one. Transporting a gram of your body over this distance consumes no more than 0.15 calories. With the bicycle, the man surpasses the possible yield of any machine and any animal evolved.

Not only in motion, also parked there is a huge difference between the space occupied by the potentially fast vehicle and the bicycle. Where a car is parked 18 bicycles fit. To leave the parking lot of a stadium, 10 000 people on a bicycle need a third of the time needed by the same number of buses.

A greater annual distance, spending less time in total and requiring less space to do so and very little investment of physical energy that is not part of its own life cycle.

Cost little. With a fraction of the hours of work that requires the gringo to buy his car, the Chinese, earning a much lower salary, buying his bicycle, which lasts a lifetime, while the car, the cheaper, the sooner there are That replenish it. The same can be said about the roads. So that a greater number of citizens can reach their homes by car, more corrodes the national territory. Inevitably the car is linked to the road, not the bicycle. Where it can not be mounted on it, the cyclist pushes it. The daily radius of journeys increases for all equally without this decreasing for the cyclist the intensity of access. The man with the bicycle becomes the owner of his own movements, without hindering the neighbor. If there are those who pretend that in terms of circulation it is possible to achieve something better, it is now when you should try it.

*: "I call traffic to the movements that are made with muscular energy of the man, and transport to those that use mechanical motors to transfer men and things. >
