certain nations may accidentally "spill over" into other nations' territory. This may prompt conflict with nations that wish to restrict access to information and communication. Current and future political and legal concerns allocation may pose may be addressed by international legislatures, such as the United Nations Committee on the Peaceful Uses of Outer Space and the International Telecommunication Union. Environmental protection More recent discussions focus on the need for the international community to draft and institute a code of space ethics to prevent the destruction of the space environment. Furthermore, the advancement of life in space pertain to questions related to the ethics of biocentrism and anthropocentrism, or in other words, determining how much value we place in all living things versus human beings specifically. Currently, researchers in the bioengineering field are working towards contamination control measures integrated into spacecraft to protect both space and earth's biosphere. Environmental space governance Beyond space debris, rocket launches and the re-entry of reusable components and space debris also cause air pollution. A study estimated their impacts on climate change and the ozone layer in 2019 and from a theoretical future space industry extrapolated from the "billionaire space race". It concludes that substantial effects from routine space tourism should "motivate regulation". Ethics In space law, ethics extend to topics regarding space exploration, space tourism, space ownership, the militarization of space, environmental protection, and distinguishing the boundaries of space itself. Human representation and participation Participation and representation of all humanity in space is an issue of international space law ever since the first phase of space exploration. Space law is called on to be understood through the contributions and relevance of countries without substantial spaceflight capabilities, particularly in the light of colonialism. Even though rights of non-spacefaring countries have been secured by declaring the exploration and use of outer space as the "province of all mankind", understanding spaceflight as its resource, sharing of space for all humanity is still criticized as imperialist and lacking. It has been argued that the present politico-legal regimes and their philosophic grounding advantage imperialist development of space. Space colonization has been discussed as particular continuation of imperialism and colonialism. Questioning colonial decisionmaking and reasons for colonial labour and land exploitation with postcolonial critique. Seeing the need for inclusive and democratic participation and implementation of any space exploration, infrastructure or habitation. While the Outer Space Treaty guarantees access to space, space
