Consequences of environmental degradation do not respect national or state boundaries and can be seen in other parts of the country or world. This can be understood by following points: (i) Land degradation affects the agricultural productivity of land as well as food security. Food requirement of that region will be completed by importing food from other regions. It will create additional pressure on the land resources of exporting regions.(ii) Addition of greenhouse gases in atmosphere is responsible for increase in temperature. It affects every part of the world whether it is developed or developing country.(iii) Addition of chlorofluorocarbon in atmosphere is responsible for ozone depletion in Antarctic region. Although source region of CFC can be any part of the world, it is a serious issue of concern for whole world.(iv) Pollution of water affected the availability of water in whole world. (v) Pollution of air has created respiratory diseases in humans of all parts of the world because harmful gases imbalanced the composition of atmosphere.

Bcz...It's all about our environment and that is more valuable than national or state boundaries.... That time Government or their citizens choose environment... bcz...if their will be environment then rules and regulation for boundaries will followed...that's why consequences of environmental degradation not respect to any boundaries whether it is national or international...

Because for eg. if one country produces a lot of pollution its effect will be seen all over the world as in the form of degradation of ozone layer
