It means that environmental degardation is not limited to a few countries, it is a matter of global concern. The statement says that irrespective of any region the consequences of environmental degradation spread not only to the area where it is degradation happens but also to the near lying areas and also at the world at large. Therefore, safeguarding the environment is an important issue not only for any particular region but for the whole world.
It is true that environmental degradation do not respect national or state boundaries.In other words, we can say that environmental degradation is not confined within a state or a nation. It has international and global affects. Its consequences are felt globally and internationally.
For example, If India is creating air pollution by massive thermal power plant or other sources, the neighbouring countries like Pakistan, Bangladesh, Srilanka are affected. It is so because acid rain, climate change do occur due to air pollution which becomes a transcontinental issue. Similarly, deforestation in Brazil has caused disturbance in rainfall pattern throughout South America.Land degradation and dam burst in India affects Bangladesh a lot as flood increases and there is more siltation.
Environmental degradation is not a nationwide or statewide issue. It is continental and global which needs precaution and protection of the natural environment.
