Which of the following is an anti-forest conservation activity

The correct option is clear felling.

Forest conservation refers to the practice of planning, maintaining, and protecting forested areas for the benefit of current and future generations. It involves activities that protect biodiversity, prevent deforestation, and sustain the ecological balance.

Let us analyze the given options to understand why clear felling is an anti-forest conservation activity:
1. Preservation of wild animals: This supports forest conservation by maintaining the food chains and ecological balance within the forest ecosystem.
2. Preservation of fires: (Likely meaning prevention or control of forest fires) This is a protective measure that prevents the destruction of large forest areas.
3. Economy in lumbering: This refers to using timber resources efficiently and minimizing waste, which reduces the pressure on forests and helps conserve them.
4. Clear felling: This is an agricultural or logging practice where all the trees in a specific area are uniformly cut down. Since it completely clears the forest cover, destroys habitats, and promotes soil erosion, it directly opposes forest conservation and is classified as an anti-forest conservation activity.
