GLASGOW, Scotland — Environmental activists expressed anger Monday at what they consider the slow pace of action to curb climate change. Youth campaigners from several countries marched on the opposite bank of the River Clyde from where the U.N. climate summit was being held, holding banners with slogans such as “We are watching you.” Swedish activist Greta Thunberg accused world leaders and government officials inside the conference of “pretending to take our future seriously.” “Change is not going to come from inside,” she said, adding: “No more blah blah blah. No, whatever the (expletive) they’re doing inside there.” Earlier Monday, Kenyan climate activist Elizabeth Wathuti made an impassioned appeal to world leaders to “open your hearts” to those already feeling the effects of global warming, saying that drought in her home country means many are going without food. So I ask you today, listen, and open up your hearts to feel the pain of the injustices and heartbreak caused by the climate and ecological crisis! Children will not live on words and empty promises! At #COP26, world leaders must open up their hearts to the reality and the act! — Elizabeth Wathuti 🇰🇪 (@lizwathuti) November 1, 2021 “As I sit comfortably here in this conference center in Glasgow, over 2 million of my fellow Kenyans are facing climate-related starvation,” she said.
