The United Nations declared the years 2000 to 2010 as the International Decade for which global campaign?

Introduction / Context:
The United Nations sometimes proclaims special International Decades to focus global attention on an important theme. From 2000 to 2010, one such decade was dedicated to musculoskeletal health, widely known as the Bone and Joint Decade. Many general knowledge and competitive exams test whether candidates remember which decade corresponded to which global campaign, so this question checks your awareness of UN thematic initiatives and their timelines.

Given Data / Assumptions:
- Time span mentioned is from the year 2000 to the year 2010.
- The question explicitly refers to an International Decade declared by the United Nations.
- Four named decades plus one additional plausible campaign are listed as options.

Concept / Approach:
To answer correctly, you need to recall which theme the UN highlighted for 2000–2010. The years 2000–2010 were associated with a global campaign focusing on bone and joint disorders such as arthritis, osteoporosis and other musculoskeletal conditions. This campaign is popularly known as the Bone and Joint Decade. Other options in the list refer either to different time periods or to separate UN initiatives. By matching the correct decade name to the given years, you can eliminate the distractors and select the correct answer confidently.

Step-by-Step Solution:
Step 1: Note the years in the question: 2000 to 2010. Step 2: Recall that an International Decade is normally associated with a clearly defined theme, often publicized through global campaigns and resolutions. Step 3: Remember that the global musculoskeletal health campaign during this period was officially referred to as the Bone and Joint Decade. Step 4: Compare this recalled information with the given options and identify the exact matching phrase. Step 5: Confirm that “Bone and Joint Decade” is the only option that correctly names the 2000–2010 International Decade, and select it as the answer.

Verification / Alternative check:
One way to verify is to cross-check other options with known timelines. The “Water for Life” Decade is linked with 2005–2015, not 2000–2010. The Second International Decade for the Eradication of Colonialism has its own separate time frame, and the decade for Natural Disaster Reduction relates to a different period as well. Since these do not align with the years 2000–2010, and the Bone and Joint Decade is specifically recognized for that exact span, the identification is consistent and reliable.

Why Other Options Are Wrong:
Water for Life Decade: This campaign is associated with 2005–2015 and focuses on water and sanitation, not the 2000–2010 period.
Second International Decade for the Eradication of Colonialism: This has its own defined years and theme that does not match the dates in the question.
International Decade for Natural Disaster Reduction: This relates to a different set of years and emphasizes disaster risk reduction, not bone and joint health.
Decade for Sustainable Energy for All: This is a plausible sounding initiative but does not correspond to the specific 2000–2010 UN-declared decade in the question.

Common Pitfalls:
A frequent mistake is to confuse the Bone and Joint Decade with the Water for Life Decade because both sound like public health or welfare initiatives. Another pitfall is assuming that any impressive sounding decade title must match the years given, without actually recalling the official time frame. Some learners also try to guess based solely on environmental themes, overlooking that musculoskeletal diseases are a major global burden and received focused attention during 2000–2010. Carefully linking the exact years to the correct decade name helps avoid these errors.

Final Answer:
Correct option: Bone and Joint Decade
