How To Reset Eminent Suitcase

Raising 'mini-cows' to reduce emissions

U.S. Some farmers raise cows in miniature - of between 80 centimeters and one meter or so - to reduce emissions of methane, because these animals emit a smaller amount of this gas the smaller, according to a study by the farmer and researcher Richard Gradwohl.

Gradwohl (pictured with one of these animals) developed in its research center 16 of the 26 races of 'mini-cows "that exist worldwide, although its initial target was to cover the needs of seven different markets, including one of the key is to pets, according to the BBC.

Thus, after years of study, the farmer discovered that this species miniature emitted lower amounts of methane - a greenhouse gas - than larger ones. "After researching many years, we found that produce much less methane," he says while pointing out that ten mini cows produce the same amount as a large one.

In this sense, Gradwohl points out that if this fact is added that in an area of \u200b\u200bfive hectares - which would come two big cows - enter ten of the 'mini' in the end, each hectare has a higher yield per kilo of meat.

This higher yield is obtained because the relationship between live weight and the amount of edible meat is not the same in a large species than small. "When an animal of 450 kilos to the slaughter, lost nearly 40 percent. It is then a response of 270 kilos and when you turn it into edible meat lose another 20 percent end up with 216 kilos," he says.

Meanwhile, in a miniature cow "you lose a lot less." "If the cow weighs about 270 kilos, when going to the slaughterhouse instead of losing 40 percent lost 30 percent and when you make what is edible meat, instead of 20 percent, losing 15 percent. Then, a small animal can produce up to 160 kilos of edible meat, "he adds. The figures are due to the small bones are smaller and have less fat.

Finally, Gradwohl says that the flesh of 'mini cow' is even more delicious as the taste is related to muscle length. "The shorter, richer meat. In that respect is similar to beef," he says.

methane Special Report, "Water that thou shalt not drink": The water cover other interests?

In many parts of the world mining progresses at a staggering pace. This involves an excessive consumption of water, and the balance of an area devastated. Miners never (or rarely) are local. This equity firms and CAD, mainly for the case of Latin America, or European capital. One might ask: why, despite being from the countries most powerful militarily and economically, and are the most interference with them, multilateral agencies, like the WB, do not realize the risks of mining to water, good at the same time claim that progress towards the shortage?

The English language dictionary of the English Royal Academy, provides the following definition: "Water: (Del lat. Aqua). Substance whose molecules are formed by the combination of an oxygen atom and two hydrogen, liquid, odorless, tasteless and colorless. It is the most abundant component of the earth's surface and more or less pure form of rain, fountains, rivers and seas is a constituent of all living organisms and appears in natural compounds. "

Let's stick to these three terms: odorless, tasteless and colorless. That is, through it would be fine. However, it appears that the current debate over water actually serves to hide other natural resources of interest. Could say that the sudden "opening the tap" of the debate on the future of water, was used to flood it all, and cover other interests.

is true that "drinking water is a scarce commodity, which is only 2.5 percent of total water in the world, while the remaining 97.5 percent is found in seas and oceans" as says Professor of History, a specialist in geopolitics, and national defense, Elsa Bruzzone. The phrase belongs to the book by Bruzzone, who is also honorary adviser of the Argentine National Congress, "Water Wars."

is also true that, as the author on the same page, "the technology to desalinate sea water there, but poses problems: it is expensive because it requires lots of energy and has not yet found a way to get rid the brine is in the process and chemicals used in it. "

Until then, all contribute to pay the theory that, to a future with access to water problems in much of the planet, this will be a vital element of conflict. No shortage of reasons to suppose, because what are background abound realize that strategy of the countries most powerful militarily and economically, to crush the weak.

Topics to think

As counterpart arise some apparent absurdities in this look. On the one hand, the groundwater reserves of the planet are more than abundant, and are well above the water surface, which would enable humanity to a long and prosperous survival. Is clear that water is not evenly distributed throughout the globe, and that these aquifers or underground reservoirs are virginal state (or nearly) in the continent militarily and economically less powerful, such as Africa and South and Central America, or some parts of Asia.

Just write it, it is possible to imagine the scene: a North American or thirsty Europe, resorting to the use of force to quench their thirst at water sources of their weaker neighbors. An image question, but ... logic?

In the worst case scenario, with a military landing in South America and Africa for the "theft" systematic water, just try to imagine the astronomical costs that would move the vital liquid to sites of consumption. How much would, then, watering crops, or to water the livestock animals? And that if the focus is productive only to the issue. The question might arise regarding what are the costs of a shower?, Or even the bathroom for a pet. In the other case, that of an invasion, accompanied by a progressive transfer of population, there is even less logical support.

Importance of forests: Climate

Climate affects the forest and determine where they develop and species that inhabit it. Simply, the forest can not exist where there is insufficient rainfall or where the temperatures are too low: these areas are occupied by the desert and tundra. The weather is the reason why fir trees do not grow in the Amazon, and why the Jaguars do not live in the boreal forest.

Earth's climate is always changing, but in the past, it has slowly, allowing forests to adapt to those changes. And as the climate affects the forest, the forest, to some extent, affects the climate.

's diverse climate helps to create diversity in the forest. Due to large variations, depending on location, the average annual temperature, precipitation and length of growing season, the types of plants and animals also vary.

However, there less diversity in a forest have been the more days that are too dry or too cold for plant growth, or the more "extreme" is the climate. Occur in any area where large fluctuations in temperature or rainfall, diversity will be limited. This is because just a few species can cope with such conditions.

The forest affects the overall climate, as well as microclimates. The tops of the trees cushioned the fall of rain that reaches the forest floor and prevent small plants from being crushed by the weight of heavy snow. Water vapor evaporates the leaves of trees, contributing to moisture levels in the area. The shade of the trees helps to prevent snow from melting too quickly and cause flooding during the spring.

forests maintain cool temperatures in the soil and wind protection. Without the impact of climate forest, many species could not persist.

Large amounts of carbon dioxide (CO2) that human activities are releasing into the atmosphere are affecting the global climate. Forests can be extremely important for reducing levels of carbon dioxide as the trees from the air and store it in their stems, leaves and roots.

trees, and most other plants capture carbon dioxide during photosynthesis and use it to produce organic molecules. But if rapid climate change kills forest trees will release more carbon dioxide when they are just increasing atmospheric levels of this molecule.

Because forests trap carbon dioxide and release oxygen, They have been an important factor in the development of the global climate. At one time there was virtually no free oxygen in the atmosphere now, several billion years later, oxygen makes up 21% of the atmosphere and can not live without it.
