Q.Explain any two human activities responsible for degradation of environment.

Human Activities Responsible for Environmental Degradation

Two major human activities that degrade the environment are deforestation and industrial pollution.

Deforestation involves the large-scale clearing of forests for agriculture, urbanization, and commercial logging. When forests are removed, soil loses its protective cover and becomes vulnerable to erosion. The loss of trees also disrupts the water cycle, reduces biodiversity as countless species lose their habitats, and contributes to climate change because forests act as carbon sinks—cutting them down releases stored carbon dioxide into the atmosphere. …

Environmental security recognizes that the health of our planet directly shapes human survival and prosperity. When we degrade natural systems, we undermine the very foundations of food, water, shelter and climate stability. Two activities illustrate this destruction with particular clarity.

Deforestation represents one of the most visible assaults on environmental integrity. When forests are cleared for agriculture, urban expansion, or timber extraction, the consequences ripple outward in multiple directions. Trees that once absorbed carbon dioxide and released oxygen disappear, accelerating climate change. Soil that was held in place by root systems erodes rapidly, washing into rivers and reducing agricultural productivity. Wildlife loses habitat, pushing species toward extinction and collapsing food webs. Water cycles change because forests no longer intercept rainfall and recharge groundwater; regions that once enjoyed reliable moisture face droughts. Indigenous communities that depend on forest resources for their livelihoods find themselves displaced. The scale matters enormously—tropical rainforests, which harbor most of Earth's biodiversity, continue to shrink at alarming rates, and each hectare lost represents an irreversible break in ecological continuity. …
