The following practices can contribute towards the conservation of natural resources except

Afforestation, contour ploughing and establishment of game reserves can contribute towards the conservation of natural resources while deforestation does not. Afforestation involves planting new forests or woodlands on land that was not previously forested, which helps to increase the overall forest cover and reduce soil erosion. Contour ploughing involves ploughing across the slope of a hill instead of up and down the slope, which helps to slow down water runoff and reduce soil erosion. Establishment of game reserves helps to protect natural habitats and biodiversity. On the other hand, deforestation involves the clearing of forests or woodlands for agricultural or commercial purposes, which can lead to soil erosion, loss of biodiversity, and climate change. Therefore, deforestation is not a practice that contributes towards the conservation of natural resources.
