Initially, when the concept of environmental security was included in global security, it usually included reacting to the conflicts that are traditionally caused by environmental problems like water shortages and energy disruptions. But its core meaning has changed over the recent years and it now includes protecting the environment and the climate as well. Environmental degradation over the years has risen because of humans themselves and it has become very important to address these issues through international policies and treaties. Even though the threat of natural disasters wasn't included in environmental security, the ideology has changed because of global warming and severe climate changes due to environmental degradation.

The term �Global security� is developed by United Nations in order to reconcile different ideas and to elaborate it with respect to everyone�s security. According to the notation, every nation has to be secure to ensure that every geographical boundary is secured. If government fails to accomplish this task then the terms like global governance, international aid and confidence building comes into picture. These factors are responsible in combating various international and national conflicts. Thus various armed forces are also being used during this process so that the citizens are protected and national safety is preserved from any injustice. Nowadays, Global Defense News means distinct to distinct people. For some it may be a source in distributing health related stuff or for few it may be providing food and energy to the surrounding or at a broader aspect, Nature.

The collection of ideas which gave birth to the concept of collective security was originally developed by the United Nations on the model that world security is the responsibility and business of all the nations.

The primary focus of this concept is to eliminate international threat through global aids and laws as well as confidence-building measures. Different things have been offered to different people by Global Defense News . As we discussed earlier in the article, there are various kinds of national securities available these days.

Environmental security is a broad section with several meanings. The most popular one is the traditional practice of taking action during conflicts being caused by environmental factors including energy disruptions, water shortages, and severe climate changes. As these problems are quite transnational, they may cause conflicts between nation-states. A new focus is to protect the climate and the environment. Humans have become the cause of few if not many environmental situations and such actions should be addressed by international governance and treaties. Natural disasters were never connected to environmental security in the past but seeing how global climate change is affecting us, it is becoming a concern and part of national environmental security.
