The biological and geological future of Earth can be extrapolated based on the estimated effects of several long-term influences. These include the chemistry at Earth's surface, the cooling rate of the planet's interior, the gravitational interactions with other objects in the Solar System, and a steady increase in the Sun's luminosity.
Human composting is emerging as an end-of-life alternative that is friendlier to the climate and the Earth — it is far less carbon-intensive than cremation and doesn’t use chemicals involved ...

As well as the cost to human life and society, there is a significant environmental impact of war. Scorched earth methods during, or after war have been in use for much of recorded history but with modern technology war can cause a far greater devastation on the environment .
The health impacts of nanotechnology are the possible effects that the use of nanotechnological materials and devices will have on human health. As nanotechnology is an emerging field, there is great debate regarding to what extent nanotechnology will benefit or pose risks for human health.
In Democracy and Development: Political Institutions and Well-Being in the World, 1950–1990 (2000), [39] Adam Przeworski argued that "democracies perform as well economically as do authoritarian regimes." [40] A study by Daron Acemoglu, Suresh Naidu, Pascual Restrepo, and James A. Robinson shows that "democracy has a positive effect on GDP ...
