insert their ideologies. Examples of this included strategic domain names and hidden propaganda content. Today, white nationalists' efforts to push their principles on the Web combined with tech companies' belief in the Internet as "raceless" motivate white nationalists to continue to exploit algorithms and influence digital spaces such as Twitter. As algorithms work in a self-reinforcing manner, they worsen the psychological effects of confirmation bias. They provide search results that confirm one's beliefs and biases and, further, connect one to communities of like-minded people. This works in favor of white nationalists; for example, search engines' autocomplete features suggest racist notions, and make White supremacist sites readily accessible to users. Environmental activism One of the earliest books on activism was Don Rittner's Ecolinking: Everyone's Guide to Online Environmental Information, published by Peachpit Press in 1992. Rittner, an environmental activist from upstate New York, spent more than 20 years researching and saving the Albany Pine Barrens. He was a beta tester for America Online and ran their Environmental Forum for the company from 1988 to when it launched in 1990. He took his early environmental knowledge and computer savvy and wrote what was called the bible of the online environmental community. It showed new Net users how to get online, find environmental information, connect to environmentalists around the world, and how to use those resources to save the planet. In August 2018, a movement of environmental activism was initiated in Sweden, by now widely known climate activist Greta Thunberg. It all started with Greta, 15 years of age at the time and influenced by the creation of #MarchForOurLives, giving her opinion on the ongoing climate change, by displaying a large sign in front of the Swedish Riksdag (parliament) in protest. This act would start the "School Strike for Climate" (SSC) (Swedish: Skolstrejk för klimatet), a movement that would eventually spread, largely through attention in media, across the globe and develop into something that came to be internationally named "Fridays for Future" (FFF). Through having children miss classes on Fridays to participate in the strike, it has from the moment it started until today, reached and affected leading governments of the world by raising environmental awareness. In 2020 in England, Wales and Northern Ireland, the National Trust began the #BlossomWatch campaign, which encouraged people to share the first signs of Spring with one another, in particular images of blossom.
