Britain's harnessing of Thames river from the perspective of peace studies and its enlightenment-research based on the background of great stink in London

In recent years, novel coronavirus has been rampant all over the world, and environmental pollution has increasingly become an unavoidable problem. The history of human development seems to be always accompanied by environmental pollution. In 1858, the appearance of the big stink in London reflected the serious pollution of Thames River in the process of industrialization. The pollution of the Thames River has aroused widespread concern of all groups in Britain, and the long road of pollution control in Britain has brought profound historical lessons. However, what future generations need to really learn from it is to get rid of the dilemma of pollution before treatment. This study takes the Thames River as an analogy, positioning human destruction of nature as the intertwined of history, and pushing the debate on environmental science, peace science, and history to a climax in order to reach wise recommendations on environmental protection, which is very necessary on the contemporary stage. While promoting the progress of human civilization, strengthening the protection of the environment may be the best way to break the traditional dilemma.

Factors influencing the variation of microplastic uptake in demersal fishes from the upper Thames River Ontario

Microplastics (plastic particles <5 mm) are abundant in aquatic environments, particularly near urban areas. Little is known, however, about how variations in microplastic abundances within watersheds affect fishes. Microplastics were examined in demersal fishes-white sucker (Catostomus commersonii) and common carp (Cyprinus carpio)-across 11 sites in the Thames River, Ontario, Canada. Microplastics were found in 44% of white sucker, ranging from 0 to 14 particles per fish, and 31% of common carp, ranging from 0 to 128 particles per fish. Across both species, the number of microplastics was higher in urban sites than rural sites, and there was a positive relationship between the number of microplastics in the fish and the abundance of microplastics in the sediment. Body mass was also positively related to number of microplastics in fish. Together these results provide insight into environmental and biological factors that may be influencing microplastic ingestion in demersal fishes.
