Community Supported Agriculture Bene ts Farms and

Farm Members

Community Supported Agriculture (CSA) is a unique social and

economic arrangement between local households and farmers

who work together to share the responsibility of producing and

delivering fresh food. Households support the farm by paying an

annual fee that entitles them to a “share” of the season’s harvest.

Once harvesting begins, members pick-up their farm share of

fresh foods which may i

Single-Hole Hollow Polymer Microspheres toward Specific High-Capacity Uptake of Target Species**

By Guijian Guan ,Zhongping Zhang ,*Zhenyang Wang ,Bianhua Liu ,Daming Gao ,and Chenggen Xie

Functionalized hollow polymer microspheres are of techno-logical importance in controlled release of drugs,protection of active species,and removal of pollutants.[1–4]Hollow poly-mer microspheres are most commonly fabricated by coating the surface of template particles with charged polyelectrolytes or reactive poly
