TOPICS FOR THE WEEK HUMAN IMPACT ON THE LOCAL AND GLOBAL ENVIRONMENT, REVIEW OF NATURAL SELECTION AND EVOLUTION

Big ideas and enduring understandings to focus on this week:Big idea 1: The process of evolution drives the diversity and unity of life.Big idea 2: Biological systems utilize free energy and molecular building blocks to grow, to reproduce and to maintain dynamic homeostasis.Big idea 3: Living systems store, retrieve, transmit and respond to information essential to life processes.Big idea 4: Biological systems interact, and these systems and their interactions possess complex properties.

Enduring Understandings:1.C Life continues to evolve within a changing environment.

2.D Growth and dynamic homeostasis of a biological system are influenced by changes in the system’s environment.

3.E Transmission of information results in changes within and between biological systems.

4.A Interactions within biological systems lead to complex properties.

4.B Competition and cooperation are important aspects of biological systems.

4.C Naturally occurring diversity among and between components within biological systems affects interactions with the environment.

Summary Assignment: In addition to completing the readings and questions below, please write a short 1-2 sentence summary of each section of the reading in your notebooks. You should try

to write down one question about the reading that you are confused about or

something that you are interested in learning more about.

(Read the previous assignment one more time. This will be helpful to think through

the material. No joke.)

Thursday

Mr Burley

Happy Thanksgiving! Take the time today to relax, spend time with your family, and ingest

large quantities of calories which will eventually be stored as fat! Be sure to tell your family

about the transfer of energy occurring during the meal. Finally, explain to them which foods make them a primary, secondary, or tertiary

consumer. Yay omnivores!

Is Human Impact Accelerating Out of Control?An Australian researcher wonders "where on Earth are we going?"

By ClimateWire and Jeremy Lovell

LONDON -- The impact of human activity on the Earth is running out of control, and the amount of time in which action can be taken to prevent potentially catastrophic climate change is rapidly dwindling, a leading scientist from the Australian National University told a global scientific climate conference in London yesterday.

Not only is the impact on the Earth's environment and climate already being seen at all levels, but the damage is accelerating, professor Will Steffen told the opening day of the four-day Planet Under Pressure conference, which has gathered together some 2,800 scientists from around the globe.

"The last 50 years have without doubt seen one of the most rapid transformations of the human relationship with the natural world," he said. "Many human activities reached takeoff points sometime in the 20th century and sharply accelerated towards the end of the century. We saw a 'great acceleration.'"

He added, "It is the scale and speed of the great acceleration that is truly remarkable. This has largely happened within one human lifetime."

Mr Burley

The conference has already declared that the Holocene Epoch is now over and that the Anthropocene -- in other words, the epoch when the impact of human activity will be clearly seen in the future in the geological record -- has already begun.

Steffen said the impact of human activity was already being felt on a planetary level on the carbon, water and nitrogen cycles, citing as an example that people now generate more reactive nitrogen artificially than the planet does naturally.

"Where on Earth are we going?" he asked, pointing to melting ice sheets and vanishing Arctic permafrost, which has the potential to release far more carbon dioxide over coming centuries than is currently produced from burning fossil fuels.

Moving beyond 'critical thresholds'

"The key point is, either we turn around a lot of these trends -- the carbon dioxide trend, deforestation and so on -- or we allow them to continue and push beyond critical thresholds," Steffen said.

Speakers at the conference pointed to the growth of so-called dead zones in coastal areas due to high carbon dioxide emissions as well as phosphorus extraction and fertilizer production, also noting higher air and oceanic temperatures, ocean acidification, biodiversity loss, growing populations and rising water stress.

Professor Diana Liverman of the University of Arizona said there were some hopeful signs -- the rate of population growth is slowing, carbon and energy intensity is starting to decline, and in some areas, forests are growing -- but they are offset by many overwhelming factors.

"Average resource consumption per person, already high in some regions, is growing steeply in emerging economies even as many poor people cannot meet basic human needs," she said. "In some countries, people are consuming far too much, including carbon, water and other resources embodied in trade. We have a long way to go to turn things around."

But sociologist Kari Marie Norgaard of the University of Oregon, who has written a book on the subject of climate change and public attitudes called "Living in Denial," said that while science may be clear -- albeit under challenge from the climate skeptics -- the general public is far from convinced.

Mr Burley

"Climate change poses a massive threat to our present social, economic and political order. From a sociological perspective, resistance to change is to be expected," she said. "People are individually and collectively habituated to the ways we act and think. This habituation must be recognized and simultaneously addressed at the individual, cultural and societal level."
