Problem: Biodiversity:

A 2007 study conducted by the National Science Foundation found that biodiversity and genetic diversity are codependent—that diversity among species requires diversity within a species, and vice versa. "If any one type is removed from the system, the cycle can break down, and the community becomes dominated by a single species." At present, the most threatened ecosystems are found in fresh water, according to the Millennium Ecosystem Assessment 2005, which was confirmed by the "Freshwater Animal Diversity Assessment", organised by the biodiversity platform, and the French Institut de recherche pour le développement (MNHNP).

What can cause a break down of a biodiversity system?

A: If any one type is removed from the system


Problem: Canadian Armed Forces:

In the 1950s, the recruitment of women was open to roles in medicine, communication, logistics, and administration. The roles of women in the CAF began to expand in 1971, after the Department reviewed the recommendations of the Royal Commission on the Status of Women, at which time it lifted the ceiling of 1,500 women personnel, and gradually expanded employment opportunities into the non-traditional areas—vehicle drivers and mechanics, aircraft mechanics, air-traffic controllers, military police, and firefighters. The Department further reviewed personnel policies in 1978 and 1985, after Parliament passed the Canadian Human Rights Act and the Canadian Charter of Rights and Freedoms. As a result of these reviews, the Department changed its policies to permit women to serve at sea in replenishment ships and in a diving tender, with the army service battalions, in military police platoons and field ambulance units, and in most air squadrons.

What charter directly affected a women's right to serve in the CAF?

A: Canadian Charter of Rights and Freedoms

Problem: Child labour:

In 2001, a voluntary agreement called the Harkin-Engel Protocol, was accepted by the international cocoa and chocolate industry to eliminate the worst forms of child labour, as defined by ILO's Convention 182, in West Africa. This agreement created a foundation named International Cocoa Initiative in 2002. The foundation claims it has, as of 2011, active programs in 290 cocoa growing communities in Côte d'Ivoire and Ghana, reaching a total population of 689,000 people to help eliminate the worst forms of child labour in cocoa industry. Other organisations claim progress has been made, but the protocol's 2005 deadlines have not yet been met.

What type of agreement was the 2001 Harkin-Engel Protocol?
