खालीलपैकी कोणता उद्देश पर्यावरण (संरक्षण) अधिनियम, 1986 मध्ये स्पष्टपणे अंतर्भूत नाही ?

The correct answer is Option D (Conservation of Land).

Key Points:
• Objectives and Long Title of Environment (Protection) Act, 1986:
• Preamble & Long Title: Explicitly enacted *"to provide for the protection and improvement of environment and for matters connected therewith"*. Objectives (1) and (2) are directly present.
• Section 2(a) and 2(b): Environment includes water, air, and land, and their relationship with human beings, other living creatures, plants, micro-organisms, and property. The Act mandates the prevention of hazards to human beings, other living creatures, plants, and property -> Objective (3) is specifically included.
• Omission: While land is part of the environment definition, general 'Conservation of Land' is a separate soil/agricultural domain and is NOT specifically enumerated as an explicit legislative object in the Preamble of this umbrella Act.
• Hence, 'Conservation of Land' is not specifically included (Option 4).
• Key Takeaway: The Environment (Protection) Act, 1986 covers environmental protection, improvement, and hazard prevention to plants; it omits specific land conservation.
