In the Southeast, a conventional crop rotation is two years of cotton followed by two years of peanuts. In this extended interview, Ron Bartel explains why farmers should consider a grass rotation, as well.
Since we last covered the California drought, conditions in the state have stayed, well, dry—very dry. Statewide, total precipitation is about equal to or below the lowest three-year period since 1895.
This interactive addresses the question if we can reduce CO2 emissions by 20% of 1990 levels and help avoid dangerous climate change? Users of this interactive can manipulate changes to various sources and uses (supply and demand) of energy with the goal of reducing C02 emissions in Great Britain by 80% in the year 2050.
This is the ninth and final lesson in a series of lessons about climate change. This lesson focuses on the various activities that humans can do to mitigate the effects of climate change. This includes information on current and predicted CO2 emission scenarios across the globe, alternative energy sources, and how people are currently responding to climate change. Importantly, this lesson is motivating in showing students that they can make a difference.
Climate-Smart Conservation: Putting Adaption Principles into Practice
May 21, 2014
This new report by the National Wildlife Federation looks at how climate change is affecting the nation’s wildlife & habitats, & addresses how natural resource managers need to prepare for and adapt to these unprecedented changes.
This activity leads students through a sequence of learning steps that highlight the embedded energy that is necessary to produce various types of food. Students start by thinking through the components of a basic meal and are later asked to review the necessary energy to produce different types of protein.
