Stop metalic sulfide mining

Mark     Meteo Eventi     0

-10.4.08- There has never been a metallic sulfide mine that has failed to pollute its watershed. Once such a reaction starts it is difficult to keep this acid drainage out of the water. When water becomes acidic it leaches out and disperses heavy metals into lakes and streams. Heavy metals are dangerous to health, wildlife, and the environment. Per saperne di più

Ensuring Species Survival

Mark     Meteo Eventi     0

-10.4.08- Fast isn�t always good. Species, for instance, are estimated to be heading towards extinction at a rate of about one every 20 minutes. That�s a pace a thousand times faster than the norm during Earth�s history. That�s not just fast, that�s out of control. And it�s definitely not good. This situation is directly tied to two issues � habitat destruction and climate change. In the same 20 minutes, we will destroy 1,200 acres of forest and emit 180,000 tons of carbon dioxide into the atmosphere worldwide. Less forest cover means fewer acres of habitat for species and more climate-changing carbon in the atmosphere. As climate, landscapes, and oceans change, species must move or adapt. Those that can�t simply die out. Per saperne di più

Stories in the ice

Mark     Meteo Eventi     0

-10.4.08- Scientists collect ice cores by driving a hollow tube deep into the miles-thick ice sheets of Antarctica and Greenland (and in glaciers elsewhere). The long cylinders of ancient ice that they retrieve provide a dazzlingly detailed record of what was happening in the world over the past several ice ages. That’s because each layer of ice in a core corresponds to a single yearor sometimes even a single seasonand most everything that fell in the snow that year remains behind, including wind-blown dust, ash, atmospheric gases, even radioactivity.
