Penn State is also making contributions towards protecting water quality. Fresh water is a limited resource, and Penn State is doing research to improve and sustain our fresh water resources. Water could become scarce someday, becoming the next generation's new oil. There are countless other amounts of research and contributions that Penn State ...
The U.S. Postal Service introduces a "Pollination" stamp series released in June 2007. The U.S. Senate passed a Resolution to protect pollinators and designates June 24–30, 2007 National Pollinator Week. "Nature's Partners", a pollinator curriculum for Grades 3-6 introduced ; First-ever pollinator provision written into the 2008 Farm Bill.
With the decline of both wild and domestic pollinator populations, pollination management is becoming an increasingly important part of horticulture.Factors that cause the loss of pollinators include pesticide misuse, unprofitability of beekeeping for honey, rapid transfer of pests and diseases to new areas of the globe, urban/suburban development, changing crop patterns, clearcut logging ...
The stamen of a corn plant, showing the pollen.. Pollen drift is the accidental cross-pollination of different varieties of crops through natural dispersal methods. The term is used almost exclusively when referring to strains of corn, and especially refers to the crossing of genetically modified crops with those that are not.
Saturation pollination is a pollination technique for agricultural crops in areas dominated by non-crop plant species that are preferred by pollinators. The technique involves keeping a larger number of bee colonies than normally maintained for honey production so as to exhaust the preferred plants and ensure visitation of the crop plants by the bees.

Forests also provide non-wood forest products, including fodder, aromatic and medicinal plants, and wild foods. Worldwide, around 1 billion people depend to some extent on wild foods such as wild meat, edible insects, edible plant products, mushrooms and fish, which often contain high levels of key micronutrients.

Increased concerns for resistance with seed mixtures include partially resistant larvae on a Bt plant being able to move to a susceptible plant to survive or cross pollination of refuge pollen on to Bt plants that can lower the amount of Bt expressed in kernels for ear feeding insects. [220] [221]
The pollination process requires a carrier for the pollen, which can be animal, wind, or human intervention (by hand-pollination or by using a pollen sprayer). Cross pollination produces seeds with a different genetic makeup from the parent plants; such seeds may be created deliberately as part of a selective breeding program for fruit trees ...
