Abstract
Global environmental challenges in 21st century are more threatening than traditional national security threats on the world because it has had effects globally and victims are completely in a state of natural disaster. The only things which can be secured from these threats are the precautionary measures before these threats occur. The excessive number of natural disaster particularly in past ten year horrified the world and transfers their attention more towards the environmental changes. The geographical location of American continent and growing military activities and WMDs testing of USA needed to focus on the rapid environmental changes around the world especially after the 20th century, because these changes affected the entire world in the shape of excessive rains, tornados and cyclones. The paper analyzes the various challenges of environment for North America particularly for United States by its own actions and in general to the world faces today, as well as measures that have been taken by entire world and United States and their future impact.
Highlights
The environmental concern started to be enunciated in the US as well as in the world during the Nixon and Carter’s regimes but the actual realization of severity of environmental threats and their effects on entire living being were very late
United States is the super power of the world but it suffered from every kind of environmental threats on one hand it has serious internal environmental problems and on other hand the global environmental changes strikes on the coasts of America with full force
Devolution and separation of power in US political system made difficult for Washington to hold its leading position in international environmental regime, for example the global biodiversity policy exhibited the weak stance of White House in front of Congress, because despite the fact that Clinton Administration achieved notable concessions at the 1992 Erath Summit in Rio di Janerio, it did not signed Convention on Biological Diversity (CBD) mainly because Congress refused to ratify the convention, same thing happened at the time of Kyoto Protocol in 1997 which was signed by USA but not ratified
Summary
The environmental concern started to be enunciated in the US as well as in the world during the Nixon and Carter’s regimes but the actual realization of severity of environmental threats and their effects on entire living being were very late. Global environmental problems were treated as major issues by world powers after 1980s, because of the rise of green movements in the industrialized nations and publications on global environmental threats such as the depletion of ozone layer, rise of global temperature, and deficiency of world’s fisheries, etc. Throughout 1970s and 1980s, the environmental apprehension raised and activists fought to placed environmental threats on the policy agenda (Doyle, & Doug, 2nd Ed 2001: 32). This awareness increased international cooperation to hold or reduce ecological degradation and unleashed a new political force, by the early 1990s, the global environment had emerged as the major policy issue in US foreign policy and in world politics. United States is the super power of the world but it suffered from every kind of environmental threats on one hand it has serious internal environmental problems and on other hand the global environmental changes strikes on the coasts of America with full force
