The Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP), previously abbreviated as TPP11 or TPP-11 before enlargement, is a multilateral trade agreement between Australia, Brunei, Canada, Chile, Japan, Malaysia, Mexico, New Zealand, Peru, Singapore, the United Kingdom and Vietnam.

The twelve members have combined economies representing 14.4% of global gross domestic product, at approximately US$15.8 trillion, making the CPTPP the world's fourth largest free trade area by GDP, behind the United States–Mexico–Canada Agreement, the European single market, and the Regional Comprehensive Economic Partnership.

The Regional Comprehensive Economic Partnership (RCEP /ˈɑːrsɛp/ AR-sep) is a free trade agreement among the Asia-Pacific countries of Australia, Brunei, Cambodia, China, Indonesia, Japan, South Korea, Laos, Malaysia, Myanmar, New Zealand, the Philippines, Singapore, Thailand, and Vietnam. The 15 member countries account for about 30% of the world's population (2.2 billion people) and 30% of global GDP ($29.7 trillion), making it the largest trade bloc in history. Signed in November 2020, RCEP is the first free trade agreement among the largest economies in Asia (excluding India), including China, Indonesia, Japan, and South Korea.

The RCEP was conceived at the 2011 ASEAN Summit in Bali, Indonesia, while negotiations formally launched during the 2012 ASEAN Summit in Cambodia. India, which took part in the initial negotiations but later decided to opt out, was invited to join the bloc at any time. Any other country or separate customs territory in the region can accede to the pact from 1 July 2023 onward. The treaty was formally signed on 15 November 2020 at the virtual ASEAN Summit hosted by Vietnam. For the first ten ratifying countries, the trade pact took effect on 1 January 2022.

There are several plausible pathways that could lead to plant and animal species extinction from climate change. Every species has evolved to exist within a certain ecological niche, but climate change leads to changes of temperature and average weather patterns. These changes can push climatic conditions outside of the species' niche, and ultimately render it extinct. Normally, species faced with changing conditions can either adapt in place through microevolution or move to another habitat with suitable conditions. However, the speed of recent climate change is very fast. Due to this rapid change, for example cold-blooded animals (a category which includes amphibians, reptiles and all invertebrates) may struggle to find a suitable habitat within 50 km of their current location at the end of this century (for a mid-range scenario of future global warming).

Climate change also increases both the frequency and intensity of extreme weather events, which can directly wipe out regional populations of species. Those species occupying coastal and low-lying island habitats can also become extinct by sea level rise. This has already happened with Bramble Cay melomys in Australia. Finally, climate change has been linked with the increased prevalence and global spread of certain diseases affecting wildlife. This includes Batrachochytrium dendrobatidis, a fungus that is one of the main drivers of the worldwide decline in amphibian populations.

The Iron Age (c. 1200 – c. 550 BC) is the final epoch of the three historical Metal Ages, after the Copper Age and Bronze Age. It has also been considered as the final age of the three-age division starting with prehistory (before recorded history) and progressing to protohistory (before written history). In this usage, it is preceded by the Stone Age (subdivided into the Paleolithic, Mesolithic and Neolithic) and Bronze Age. These concepts originated for describing Iron Age Europe and the ancient Near East. In the archaeology of the Americas, a five-period system is conventionally used instead; indigenous cultures there did not develop an iron economy in the pre-Columbian era, though some did work copper and silver. Indigenous metalworking arrived in Australia with European contact. Although meteoric iron has been used for millennia in many regions, the beginning of the Iron Age is defined locally around the world by archaeological convention when the production of smelted iron (especially steel tools and weapons) replaces their bronze equivalents in common use.

In Anatolia and the Caucasus, or Southeast Europe, the Iron Age began c. 1300 BC. In the ancient Near East, this transition occurred simultaneously with the Late Bronze Age collapse, during the 12th century BC. The technology soon spread throughout the Mediterranean basin region and to South Asia between the 12th and 11th centuries BC. Its further spread to Central Asia, Eastern Europe, and Central Europe was somewhat delayed, and Northern Europe was not reached until c. the 5th century BC.

The Cenozoic Era (also known as Caenozoic, Kainozoic, or Neozoic Era; /ˌsiːnəˈzoʊ.ɪk, ˌsɛn-/; SEE-nə-ZOH-ik, SEN-ə-; lit. 'new life') is Earth's current geological era, representing the last 66 million years of Earth's history. It is characterized by the dominance of mammals, insects, birds and angiosperms (flowering plants). It is the latest of three geological eras of the Phanerozoic Eon, preceded by the Mesozoic and Paleozoic. The Cenozoic started with the Cretaceous–Paleogene extinction event, when many species, including the non-avian dinosaurs, became extinct in an event attributed by most experts to the impact of a large asteroid or other celestial body, the Chicxulub impactor.

The Cenozoic is also known as the Age of Mammals because the terrestrial animals that dominated both hemispheres were mammals – the eutherians (placentals) in the Northern Hemisphere and the metatherians (marsupials, now mainly restricted to Australia and to some extent South America) in the Southern Hemisphere. The extinction of many groups allowed mammals and birds to greatly diversify so that large mammals and birds dominated life on Earth. The continents also moved into their current positions during this era.

American Civil War reenactment is an effort to recreate the appearance of a particular battle or other event associated with the American Civil War by hobbyists known (in the United States) as Civil War reenactors, or living historians.

Although most common in the United States, there are also American Civil War reenactors in Canada, the United Kingdom, Germany, Australia, Italy, Denmark, Sweden, and Poland.

Soil fertility refers to the ability of soil to sustain agricultural plant growth, i.e. to provide plant habitat and result in sustained and consistent yields of high quality. It also refers to the soil's ability to supply plant/crop nutrients in the right quantities and qualities over a sustained period of time. A fertile soil has the following properties:

• The ability to supply essential plant nutrients and water in adequate amounts and proportions for plant growth and reproduction; and
• The absence of toxic substances which may inhibit plant growth e.g. Fe which leads to nutrient toxicity.

The following properties contribute to soil fertility in most situations:

The title of reader in universities in the United Kingdom and some Commonwealth of Nations such as India, Australia and New Zealand denotes an appointment for a senior academic with a distinguished international reputation for research or scholarship.

In the traditional hierarchy of British and other Commonwealth universities, reader (and principal lecturer in the new universities) is an academic rank above senior lecturer and below Chaired Professor. Comparatively speaking, a reader can be thought of as a professor but without a chair, similar to the distinction which can be found in universities in the United States, China (Hong Kong) and some parts of Europe.

A Commonwealth realm is a sovereign state in the Commonwealth of Nations that has the same constitutional monarch and head of state as the other realms. The current monarch is King Charles III. Except for the United Kingdom, in each of the realms the monarch is represented by a governor-general. The phrase Commonwealth realm is an informal description not used in any law.

As of 2025, there are 15 Commonwealth realms: Antigua and Barbuda, Australia, The Bahamas, Belize, Canada, Grenada, Jamaica, New Zealand, Papua New Guinea, Saint Kitts and Nevis, Saint Lucia, Saint Vincent and the Grenadines, Solomon Islands, Tuvalu, and the United Kingdom. While the Commonwealth of Nations has 56 independent member states, only these 15 have Charles III as head of state. He is also Head of the Commonwealth, a non-constitutional role.

The Punjabi diaspora consists of the descendants of ethnic Punjabis who emigrated out of the Punjab region in Pakistan and India to the rest of the world. Punjabis are one of the largest ethnic groups in both the Pakistani and Indian diasporas. The Punjabi diaspora numbers around the world has been given between 3 and 5 million, mainly concentrated in Britain, Canada, the United States, Western Europe, Southeast Asia, the Middle East, Australia and New Zealand.
