In his book Mutual Aid‚ Peter Kropotkin argues against Social Darwinism‚ a concept that supports ‘every man for himself’ notion. Kropotkin states that Darwin’s concept was about the competition among different species and not among members of the same species as if often alluded (Kropotkin 2006). His argument is that the survival of a species is only guaranteed through mutual aid. The book is full of examples of scenarios where members of the same species relied on each other for survival‚ including

Hydrogen has been used for space flight since the 1950s. Learn more about hydrogen and fuel cells from the National Aeronautics and Space Administration. Hydrogen also can be used to fuel internal combustion engines and fuel cells‚ both of which can power zero to nearzeroemissions vehicles‚ such as hydrogen fuel cell vehicles. Major research and development efforts are aimed at making hydrogen fuel cell vehicles practical for widespread use. Additionally‚ hydrogen can be blended with natural gas to create hythane
