Only Statement 1 is correct.

Statement 1: The United Nations Conference on Human Settlements (HABITAT) in 1976 aimed to address the quality of life in human settlements.

• This statement is correct.
  • The United Nations Conference on Human Settlements (HABITAT) took place in 1976 in Vancouver, Canada.
  • The conference focused on issues related to urbanization, housing, and the quality of life in human settlements around the world. It aimed to improve living conditions, promote sustainable urban development, and address the challenges posed by rapid urban growth.
  • Therefore, Statement 1 accurately reflects the purpose and goals of the 1976 HABITAT conference.

Statement 2: World Environment Day, observed annually on June 5th, commemorates the opening day of the United Nations Water Conference.

• This statement is incorrect.
  • World Environment Day, observed every year on June 5th, does not commemorate the opening day of the United Nations Water Conference.
  • World Environment Day was established to commemorate the opening day of the United Nations Conference on the Human Environment held in Stockholm in 1972. This conference marked the first major international gathering to address global environmental issues such as pollution, health threats, and sustainable development.
  • The United Nations Water Conference took place in 1977, but it is not the event commemorated by World Environment Day. Therefore, Statement 2 is incorrect.

Conclusion:

Since Statement 1 is correct and Statement 2 is incorrect, the correct answer is:

B) Only Statement 1 is correct.

Hence, Option B Is Correct.

Statement 1 is correct, but Statement 2 is incorrect.

Statement 1: The United Nations Water Conference and the United Nations Conference on Desertification were both held in 1977.

• This statement is correct.
  • The United Nations Water Conference took place in 1977 in Mar del Plata, Argentina. It focused on global water issues, including water scarcity, pollution, and the need for international cooperation in water resource management.
  • The United Nations Conference on Desertification (UNCOD) also took place in 1977 in Nairobi, Kenya. The conference addressed the growing problem of desertification (the degradation of land into desert-like conditions) and its impact on agriculture, livelihoods, and the environment.
  • Both conferences were held in the same year (1977), which makes Statement 1 accurate.

Statement 2: The United Nations Conference on Human Settlements (HABITAT) took place in 1980 to address issues related to urban development.

• This statement is incorrect.
  • The United Nations Conference on Human Settlements (HABITAT) was actually held in 1976, not in 1980.
  • The conference took place in Vancouver, Canada, and its main goal was to discuss the quality of life in human settlements, particularly focusing on issues such as urbanization, housing, and improving living conditions in cities and towns worldwide.
  • A second HABITAT Conference (HABITAT II) was held in Istanbul, Turkey, in 1996, but the first one was in 1976, making Statement 2 incorrect.

Conclusion:

Since Statement 1 is correct and Statement 2 is incorrect, the correct answer is:

A) Statement 1 is correct, but Statement 2 is incorrect.

Hence, Option A Is Correct.

Only Statement 1 is correct.

Statement 1: World Environment Day, observed on June 5th, was established to commemorate the anniversary of the opening day of the United Nations Conference on the Human Environment in 1972.

• This statement is correct.
  • World Environment Day is indeed observed annually on June 5th to commemorate the opening day of the United Nations Conference on the Human Environment, which took place in Stockholm in 1972.
  • The 1972 conference was a milestone event, marking the first time that environmental issues were discussed at the international level. To honor the significance of this event and raise awareness about environmental issues, World Environment Day was established to be observed on June 5th every year.

Statement 2: The United Nations Conference on Human Settlements (HABITAT) held in 1976 resulted in the formation of "Earthwatch," a program focused on sustainable development.

• This statement is incorrect.
  • The United Nations Conference on Human Settlements (HABITAT) was indeed held in 1976, and its main focus was on addressing urbanization, housing, and the quality of life in human settlements. However, "Earthwatch" was not a program that emerged from this conference.
  • The Earthwatch program was actually created as part of the 1972 United Nations Conference on the Human Environment (Stockholm), not the 1976 HABITAT conference. The Earthwatch program aimed to monitor global environmental problems and provide early warnings of environmental crises, particularly concerning pollution and degradation of natural resources.
  • Therefore, Statement 2 is incorrect because Earthwatch was a result of the 1972 Stockholm conference, not the 1976 HABITAT conference.

Conclusion:

• Statement 1 is correct because World Environment Day was established to commemorate the anniversary of the opening of the 1972 Stockholm conference.
• Statement 2 is incorrect because Earthwatch was a product of the 1972 conference, not the 1976 HABITAT conference.

Thus, the correct answer is:

B) Only Statement 1 is correct.

Hence, Option B Is Correct.
