Question

Arrange the following environment - related events in chronological order:
A. Antarctic Treaty
B. Brundtland Commission Report
C. UN Convention on the Law of the Sea
D. Paris Agreement on the Climate Change
E. UN Conference on Environment and Development
Choose the correct answer from the options given below:

• A. A, C, B, E, D
• B. A, E, C, D, B
• C. E, A, B, D, C
• D. E, B, C, A, D

Hint:

To remember the sequence, think of the Scope: first we protected a Continent (Antarctica), then the Oceans (Law of the Sea), then we defined Sustainability (Brundtland), and finally we tackled the Global Climate (Paris).

Answer 1

The Correct Option is A

Concept: International environmental governance has evolved through a series of landmark treaties and reports that have shaped how nations manage global commons and address climate change.

Step 1: Timeline of Cold War and Resource Treaties.
The earliest event in this list is the Antarctic Treaty (A), signed in 1959. It was a major milestone that set aside Antarctica as a scientific preserve and banned military activity on the continent. This was followed by the UN Convention on the Law of the Sea (C), which was opened for signature in 1982 after years of negotiation to define the rights and responsibilities of nations in their use of the world's oceans.

Step 2: The Rise of Sustainable Development.
In 1987, the Brundtland Commission Report (B), also known as "Our Common Future," was published. This report was revolutionary as it provided the first widely accepted definition of "sustainable development." This intellectual shift led directly to the UN Conference on Environment and Development (E), commonly known as the Rio Earth Summit, in 1992.

Step 3: Contemporary Climate Action.
The most recent event is the Paris Agreement on Climate Change (D), which was adopted in 2015. Unlike earlier frameworks, it set a global goal to limit global warming to well below 2 degrees Celsius compared to pre-industrial levels.
