- World Report 2024: Canada (hrw.org)
Since assuming office in 2015, the government of Prime Minister Justin Trudeau has taken significant steps to advance human rights at home and abroad. Despite progress in a few key areas, a range of deeply entrenched challenges remain. These include wide-ranging abuses against Indigenous peoples and immigration detainees, including people with disabilities. Canada’s failures to mitigate the impacts of climate change and provide adequate government support are also leading to violations in Indigenous communities across the country while compounding risks for people with disabilities, children, and older people.
- Cambrian (Wikipedia)
The Cambrian Period ( /ˈkæmbri.ən, ˈkeɪm-/ KAM-bree-ən, KAYM-; sometimes symbolized Ꞓ) is the first geological period of the Paleozoic Era, and of the Phanerozoic Eon. The Cambrian lasted 53.4 million years from the end of the preceding Ediacaran Period 538.8 million years ago (mya) to the beginning of the Ordovician Period 485.4 mya. Its subdivisions, and its base, are somewhat in flux. The period was established as “Cambrian series” by Adam Sedgwick, who named it after Cambria, the Latin name for ‘Cymru’ (Wales), where Britain’s Cambrian rocks are best exposed. Sedgwick identified the layer as part of his task, along with Roderick Murchison, to subdivide the large “Transition Series”, although the two geologists disagreed for a while on the appropriate categorization. The Cambrian is unique in its unusually high proportion of lagerstätte sedimentary deposits, sites of exceptional preservation where “soft” parts of organisms are preserved as well as their more resistant shells. As a result, our understanding of the Cambrian biology surpasses that of some later periods.
