Istoria o scriu invingatorii; motivul pentru care nu invatam nimic din greselile trecutului

Istoria o scriu invingatorii; motivul pentru care nu invatam nimic din greselile trecutului

Oficial, in 1962, URSS a incercat sa instaleze rachete nucleare in Cuba si numai insistenta cu care presedintele Kennedy a presat Moscova in timpul celor 13 zile de criza a determinat retragerea armelor din coasta Americii. Lumea fusese salvata inca o data. Cam asta ne spune istoria ca s-a intamplat. Cu singurul amendament ca totul […]

First detailed map of aboveground forest carbon stocks in Mexico unveiled

«The release of this data set is an important step forward in the accounting for carbon flux in Mexico and in supporting efforts to reduce carbon emissions from the land sector,» says Dr. Kellndorfer. «We see the potential for these biomass data sets to be generated by other tropical nations.» Credit: Map Credit: Remote Sensing […]

Saving lonely species is important for environment

Endemic eucalyptus found on Tasmania has evolved to live in a variety of conditions that exist from sea level to tree line. These include hot, cold, wet, and dry habitats. Credit: Joe Bailey The lemur, Javan rhino and Santa Cruz kangaroo rat are all lonesome animals. As endemic species, they live in habitats restricted to […]

Диеты – польза и вред диет

Диеты – польза и вред диет

Полезны ли диеты? Этот вопрос должны задавать себе каждый человек, который собирается «сесть» на диету, и неважно вы парень или девушка. Но многие молодые люди, в погоне за самоусовершенствованием, просто напросто игнорируют, а зачастую не хотят даже знать о возможных последствиях произвольного, бесконтрольного применения диет. Многие люди имеют цель похудеть любыми методами, любой ценой, большей […]

Пластиковые водопроводные трубы не так экологически безопасны, как считалось: исследование

Пластиковые водопроводные трубы не так экологически безопасны, как считалось: исследование

Как сообщается в исследовании, опубликованном не так давно в онлайн-журнале Water Research, пластиковые водопроводные трубы, используемые при строительстве экологически чистых «зеленых» зданий в Соединенных Штатах, как оказалось, выделяют в питьевую воду химические вещества, которые не только вызывают неприятные запахи, но и порой превышают предельно допустимые гигиенические нормы. В современных зданиях в USA устанавливаются несколько типов […]

Climate change not responsible for altering forest tree composition, experts say

Credit: Mary Ann Fajvan, West Virginia University, Bugwood.org     Change in disturbance regimes — rather than a change in climate — is largely responsible for altering the composition of Eastern forests, according to a researcher in Penn State’s College of Agricultural Sciences. Forests in the Eastern United States remain in […]

Building a bridge from basic botany to applied agriculture

Building a bridge from basic botany to applied agriculture

One of the planet’s leading questions is how to produce enough food to feed the world in an increasingly variable climate. The Food and Agriculture Organization of the United Nations predicts that food production must rise 70% over the next 40 years to feed a growing global population, and plants are one major component of […]

Dezastru ecologic pe riul Lapus

Dezastru ecologic pe riul Lapus

Nimic nu prevestea ca pe riul Lapus s-ar putea produce un asemenea dezastru ecologic de proportii! Riul ce izvoraste din Muntii Varatec curgea pina acum domol, ducindu-si apa curata si limpede ca lacrima spre varsarea in riul Somes. Dar nesabuinta unor oameni vine sa tulbure echilibrul naturii. Cetatenii din localitatile Poiana Botizii, Lapus, Rogoz, Damacuseni […]

Breathing sand: New measurement technique detects oxygen supply to bottom of North Sea

Breathing sand: New measurement technique detects oxygen supply to bottom of North Sea

New analytical methods show for the first time, how the permeable, sandy sediment at the bottom of the North Sea is supplied with oxygen and which factors determine the exchange. Because the metabolic rate is particularly high in this type of seabed, and the sediments are permeable, measurements are particularly complicated. Based on the detailed […]

Mediterranean, semi-arid ecosystems prove resistant to climate change

Mediterranean, semi-arid ecosystems prove resistant to climate change

Climate change predictions for the Middle East, like other arid regions of the world, are alarming. In an area known for its water scarcity, rainfall is expected to decrease even further in the near future, spelling disaster for the functioning of unique ecosystems — hotspots of biodiversity and rich genetic fodder for essential crops. To […]
