The space field should be used peacefully, jointly protect the space field from harm, and maximize space utilization through environmental, economic, and security exploration of space. [16] These consensuses also clarify the relationship between space sustainability and international security, that states and individuals explore space for ...
Arrangement of global catastrophic risks into three sets according to whether they are largely human-caused, human influences upon nature, or purely natural. Anthropogenic risks are those caused by humans and include those related to technology, governance, and climate change.
Carbon dioxide is a greenhouse gas, meaning it causes heat to get trapped in the atmosphere, rather than being released into space, raising the Earth's temperature – known as global warming. [303] Alongside greenhouse gas emissions the industry is also responsible for almost 35% of microplastic pollution in the oceans. [302]
Space and survival is the idea that the long-term survival of the human species and technological civilization requires the building of a spacefaring civilization that utilizes the resources of outer space, [1] and that not doing this might lead to human extinction. A related observation is that the window of opportunity for doing this may be ...
Passage through the solar system could result in the destruction of the Earth or the Sun by being directly consumed. Astronomers expect the collision of the Milky Way Galaxy with the Andromeda Galaxy in about four billion years, but due to the large amount of empty space between them, most stars are not expected to collide directly.

This could render the space around Earth untraversable for space missions and unsuitable for the use of satellites. As of March 2022, there are no legally binding international laws about who is responsible for the extraction of space debris, or mandating a reduction of new space debris brought into Earth's orbit.

The two most common reasons in favor of colonization are the survival of humans and life independent of Earth, making humans a multiplanetary species, [6] in the event of a planetary-scale disaster (natural or human-made), and the commercial use of space particularly for enabling a more sustainable expansion of human society through the ...
Space exploration also gives scientists the ability to perform experiments in other settings and expand humanity's knowledge. [67] Another claim is that space exploration is a necessity to humankind and that staying on Earth will eventually lead to extinction. Some of the reasons are lack of natural resources, comets, nuclear war, and worldwide ...
