Cari Hutan's "In Search of Forest"
An AMAZING film consisting of primary research in Kalimantan, Malaysia investigating the reasons behind deforestation of tropical rainforest. A IB graduate of Jakarta International School in 2010 started this film during his last IB year. Enlightening, frank and entertaining. A real eye-opener exploring why deforestation can be such a complex issue. Also effectively outlines the tropical peat bog system. This film touches really on so many portions of this curriculum that it is unfair just to put it into one. Can fit in also into, The Ecosystem, Conservation and biodiversity, Pollution management, Global warming and the Environmental Value System.

There's a tight and surprising link between the ocean's health and ours, says marine biologist Stephen Palumbi. He shows how toxins at the bottom of the ocean food chain find their way into our bodies, with a shocking story of toxic contamination from a Japanese fish market. His work points a way forward for saving the oceans' health -- and humanity's. media type="custom" key="23992212" align="center"

In the first measurement of this trend, the research showed humans are using an increasing amount of Earth's annual production of photosynthetic land plants and that consumption rose from 20 to 25 percent from 1995 to 2005. media type="custom" key="25008738" = **__Topic 2.6__** =

Paul Andersen explains the differences between an r and a K selected species. He starts with a brief description of population growth noting the importance of; r or growth rate, N or number of individuals in the population, and K the carrying capacity. He describes three different survivorship curves found in organisms. He lists the characteristics of r-selected species like bacteria and K-selected species like humans. media type="custom" key="25085132"

"When we try to pick out anything by itself, we find it hitched to everything else in the Universe." - John Muir

When wolves were reintroduced to Yellowstone National Park in the United States after being absent nearly 70 years, the most remarkable "trophic cascade" occurred. What is a trophic cascade and how exactly do wolves change rivers? George Monbiot explains in this movie remix. media type="custom" key="25136320" In the world of ecology, the only constant is change - but change can be good. Today Hank explains ecological succession and how ecological communities change over time to become beautiful, biodiverse mosaics. media type="custom" key="25152944" This is an educational video illustrating the natural progression of our plant and wildlife eco-system. The video depicts the separate stages of ecological succession from the initial barren beginnings to the final phase, the climax forest. This video was produced by Jared Buck of Buck & Sons Landscape for elementary school level students. media type="custom" key="25152994" = **__Topic 2.7 Environmental Impact Assessment (EIA)__** = A quick overview of EIA made specifically for the IB Environmental Systems and Societies course but a useful overview for anyone who wants to know more about the ideal EIA process. media type="custom" key="25208396"
