by crashcourse - http://www.youtube.com/watch?v=kdDSRRCKMiI - Hank talks about the last major way humans are impacting the environment in this penultimate episode of Crash Course Ecology. Pollution takes many forms - from the simplest piece of litter to the more complex endocrine distruptors - and ultimately, humans are responsible for it all. [More] [Less]

By crashcourse - http://www.youtube.com/watch?v=leHy-Y_8nRs - Hank describes the desperate need many organisms have for nutrients (specifically nitrogen and phosphorus) and how they go about getting them via the nitrogen and phosphorus cycles.

By crashcourse - http://www.youtube.com/watch?v=2D7hZpIYlCA - Hank introduces us to biogeochemical cycles by describing his two favorites: carbon and water. The hydrologic cycle describes how water moves on, above, and below the surface of the Earth, driven by energy supplied by the sun and wind. The carbon cycle does the same... for carbon!

By crashcourse - http://www.youtube.com/watch?v=v6ubvEJ3KGM - Hank brings us to the next level of ecological study with ecosystem ecology, which looks at how energy, nutrients, and materials are getting shuffled around within an ecosystem (a collection of living and nonliving things interacting in a specific place), and which basically comes down to who is eating who.

by crashcourse - http://www.youtube.com/watch?v=jZKIHe2LDP8 - 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.

Global plastic pollution - a problem facing all of us, not just albatross and not just Hawaiians. The only way to stop it is to stop using plastic as a throwaway material.

All levels of agro productivity...from the ground to the fruit to the timber...makes a nice balanced Food forest!

John Evans shows the secret for growing healthy enormous World Record vegetables is organic Bountea compost tea.

In the north east pacific ocean, covering an area more then twice the size of Texas, there is a huge deposit of floating plastic. But what is being done about it?

Food Forestry is urban agriculture that encourages abundant food systems. Growing food locally helps create a local food economy and eliminates transportation costs. We utilize natural growing techniques and permaculture concepts to produce healthy food for urban folks. This garden was created at Crenshaw High School in South Central LA, California in 2005. Adonijah Miyamura EL featured here trained Eugene Cooke and many others in this unique practice. www.gebsite.com [More] [Less]

by crashcourse - http://www.youtube.com/watch?v=sjE-Pkjp3u4 - The History of Life on Earth - with Hank Green. We\\\'ll be learning how the living things interact with and influence each other and their environments. Life is powerful, and in order to understand how living systems work, you first have to understand how they originated, developed and diversified over the past 4.5 billion years of Earth\\\'s history. Hang on to your hats as Hank tells us the epic drama that is the history of life on Earth. [More] [Less]
