11/14/2011 – NEW ProCon.org Website! – Should churches (defined as churches, temples, mosques, synagogues, etc.) remain tax-exempt? – US churches have been exempt from paying income and property taxes since the country's founding. Debate continues over whether or not these tax benefits should be retained, especially during our tough economic times. Proponents argue that a tax exemption keeps the government out of church finances, and that churches deserve a tax break because they provide crucial social services. Opponents argue that giving churches special tax exemptions violates the separation of church and state, and that the government cannot afford what amounts to a subsidy worth billions of dollars every year. Our 44th website explores the pros and cons in the debate over church tax exemptions.

10/27/2011 - NEW: Should cannabidiol (CBD) be a medical option? - Cannabidiol (CBD) is the main non-psychoactive chemical component of marijuana. The US Department of Health and Human Services (HHS) was awarded a patent for CBD on Oct. 7, 2003. However, the US Drug Enforcement Agency (DEA) classifies CBD as a Schedule I drug, meaning it is considered to have "no accepted medical use,” "a high potential for abuse,” and "a lack of accepted safety for use of the drug or other substance under medical supervision." Given the large volume of studies on CBD, the HHS patent of this Schedule I drug, and the growing attention CBD receives, we have compiled the best pro and con arguments from major players in the CBD debate to help our readers better understand this controversy.

Proponents say standardized tests are a fair and objective measure of student achievement, and that they ensure teachers and schools are accountable. Opponents say the tests are neither fair nor objective, and that their use narrows the curriculum and promotes "teaching to the test."

1/13/2011 NEW ProCon.org Website! - Should teachers get tenure? - Teacher tenure is the increasingly controversial form of job protection that public school teachers in all states receive after 1-7 years on the job. Proponents of tenure argue that it protects teachers from being fired for personal or political reasons, and prevents the firing of experienced teachers to hire less expensive new teachers. Opponents argue that this job protection makes the removal of poorly performing teachers so difficult and costly that most schools end up retaining their bad teachers, and that tenure is no longer needed given current laws against job discrimination.
ProCon.org's 40th website explores the pros and cons of whether or not teachers should get tenure.

Some people argue that rising levels of human-produced greenhouse gases are warming the planet and causing the climate to change.
