Abstract
Human rights and the environment are linked with each other in two ways. Firstly, the environment is seen as pre-condition of realization of human rights. Because human beings are dependent on the environment. We all meet our basic needs including air, water and food from nature. Individuals cannot exist without the mother earth. For this reason, human rights may not be enjoyed at the absence of a clean environment. Secondly, human rights can be an effective way to achieve environmental safety. These two linkages are united under the umbrella of environmental human rights. Environmental human rights are the rights of people to protect the environment for the sake of human beings. There have been numerous studies investigating the scope and types of environmental human rights. However, how the linkage between human rights and the environment has been evolved has not been discussed sufficiently so far. Accordingly, this paper aims to explore how environmental human rights have been developed over history. This research finds that environmental human rights have been developed by international environmental law more than international human rights law.
