However, Greenpeace is controversial as it undertakes unlawful actions and methods, thus a major source of criticism. This has led to fines, suspended sentences and damaging property. Furthermore, a Canadian ecologist Patrick Moore, an early Greenpeace member left the organization when in 1986; decided to support a universal ban on chlorine in drinking water. Moore has argued that Greenpeace today is motivated by politics rather than science and that none of his “fellow directors had any formal science education”. However, Moore is not as ready as he is made out to be, as he has also reversed his position on nuclear power in 1976, first opposing it and then supporting it.
