"This is not an environmental book, even though it is concerned with the environment. It is not a book to save the world, even though the world is clearly in trouble. Ultimately, A Matter Of Scale is a book about survival; about ensuring that every individual human has the means to save herself or himself from the crisis that is unfolding. And there most certainly is a crisis; like the waves of a surging river; small and irregular at first, but growing larger, creating whirlpools, rising in treacherous white water, and eventually inundating everything in its path. People know that the climate is changing, that species are being removed from the Earth at a rapidly increasing rate, that entire ecosystems are becoming shadows of their former richness; they know, but they do not understand. The environmental crisis is closing in on humanity from all directions, yet the crisis barely registers on this culture's list of problems. As we stand, humanity is doomed to a collapse that will leave only a few nomads, and a toxic, barely survivable Earth in its wake."

"Striking evidence has emerged that an ancient virus previously known only from fossil evidence has persistently infected some humans at very low levels for hundreds of thousands or even millions of years. This ancient retrovirus is a kind of living fossil, and the discovery of an intact copy of it within the human genome poses questions as to how it has survived, and suggests others from the distant evolutionary past may lie dormant in the DNA of many species. ..."

"What does that mean exactly? It means you play in a multiplayer world that has the possibility of being permanently destroyed, resulting in server-wide perma death. What's more, the reason it's destroyed would be the players' own fault. It's not that different from our own world in that way. "This ecosystem is your only lifeline in a race against time." It works like this: a new server is started, and players enter at the beginnings of civilization. There's a world-destroying cataclysm looming, like a drought or a flood or a meteor heading for the Earth, several real-time weeks away. In order to prevent that catastrophe from happening, you need to build a civilization and advance technology and resources to the point that the crisis can be averted. However you're not alone in this world. Besides the other players, you'll be sharing the world with a detailed wilderness simulation full of plants and animals. They simulate 24 hours a day, living out their lives with or without human interaction, growing, feeding and reproducing. Together they form an ecosystem rich with resources, resources that you must use to survive and develop a civilization."

"Close Reading and Argument Writing - Authentically Across the Curriculum 7/16/2015 0 Comments Close reading of informational texts and non-fiction articles is not - and should not be - reserved for language arts classes. Every content area would be immensely enhanced if science teachers, social studies teachers, physical education teachers, welding teachers, woodworking teachers (in other words, "all technical subjects," as Common Core states) would not push aside the textbook, but instead embrace it, along with content area and trade articles. Students would then simultaneously learn how to dissect the readings while gaining knowledge in these content areas. What often happens is that teachers feel that students can't handle the text books or can't read the articles independently - and often that is true. However, when teachers instead go into a survival mode, of sorts, and read aloud the whole chapter or article or summarize it with a slideshow, it ends up doing a disservice to students - students are not learning HOW to read these complex texts. They are not learning how to acquire the information on their own. They are not being given the skills to read the sometimes intricate information within a particular content area or even within their possible future trade. They are not being given the opportunity to read, understand, articulate, and discuss or even debate topics within their area of study. Teachers sometimes feel that they can't do these things with students because they are not language arts teachers, or because they don't have time, or simply because they don't know how. Alternatively, a simple solution is to let go of the control and let students do…..with the guidance called close reading. Close reading is a guided reading approach. It is guided because 1) the close reading strategy is reserved for complex texts that are often too high for students to be left with independently and 2) students don't use close reading strateg

"The transition from unicellular to multicellular life was one of a few major events in the history of life that created new opportunities for more complex biological systems to evolve. Predation is hypothesized as one selective pressure that may have driven the evolution of multicellularity. Here we show that de novo origins of simple multicellularity can evolve in response to predation. We subjected outcrossed populations of the unicellular green alga Chlamydomonas reinhardtii to selection by the filter-feeding predator Paramecium tetraurelia. Two of five experimental populations evolved multicellular structures not observed in unselected control populations within ~750 asexual generations. Considerable variation exists in the evolved multicellular life cycles, with both cell number and propagule size varying among isolates. Survival assays show that evolved multicellular traits provide effective protection against predation. These results support the hypothesis that selection imposed by predators may have played a role in some origins of multicellularity."

"Our core ecological problem is not climate change. It is overshoot, of which global warming is a symptom. Overshoot is a systemic issue. Over the past century-and-a-half, enormous amounts of cheap energy from fossil fuels enabled the rapid growth of resource extraction, manufacturing, and consumption; and these in turn led to population increase, pollution, and loss of natural habitat and hence biodiversity. The human system expanded dramatically, overshooting Earth's long-term carrying capacity for humans while upsetting the ecological systems we depend on for our survival. Until we understand and address this systemic imbalance, symptomatic treatment (doing what we can to reverse pollution dilemmas like climate change, trying to save threatened species, and hoping to feed a burgeoning population with genetically modified crops) will constitute an endlessly frustrating round of stopgap measures that are ultimately destined to fail."
