John Todd (Canadian Biologist)
John Todd (born 1939) is a Canadian biologist working in the general field of ecological design. He addresses problems of food production and wastewater processing by using ecosystems technologies that incorporate plants, animals and bacteria. Todd has developed "Arks" or "bioshelters", ecologically closed "life-support systems" with the goal of sustainable functioning. He combines alternative technologies for renewable energy, organic farming, aquaculture, hydroponics and architecture to create "living machines" or "eco-machines". John Todd is a co-founder with Nancy Jack Todd of the non-profits New Alchemy Institute (1969–1991) and Ocean Arks International (1981), and the founder and president of the design and engineering firm John Todd Ecological Design Inc. (1989). A research professor emeritus and distinguished lecturer at the University of Vermont, Todd has published books on ecological design, as well as over 200 scientific papers, popular articles and essays.

Hamilton, Ontario
Hamilton is a port city in the Canadian province of Ontario. Hamilton has a population of 569,353, and its census metropolitan area, which includes Burlington and Grimsby, has a population of 785,184. The city is approximately southwest of Toronto in the Greater Toronto and Hamilton Area (GTHA). Conceived by George Hamilton when he purchased the Durand farm shortly after the War of 1812, the town of Hamilton became the centre of a densely populated and industrialized region at the west end of Lake Ontario known as the Golden Horseshoe. On January 1, 2001, the current boundaries of Hamilton were created through the amalgamation of the original city with other municipalities of the Regional Municipality of Hamilton–Wentworth. Residents of the city are known as Hamiltonians. Traditionally, the local economy has been led by the steel and heavy manufacturing industries. During the 2010s, a shift toward the service sector occurred, such as health and sciences. Hamilton is ho ...

Organic Farming
Organic farming, also known as ecological farming or biological farming,Labelling, article 30 o''Regulation (EU) 2018/848 of the European Parliament and of the Council of 30 May 2018 on organic production and labelling of organic products and repealing Council Regulation (EC) No 834/2007.''/ref> is an agricultural system that uses fertilizers of organic origin such as compost manure, green manure, and bone meal and places emphasis on techniques such as crop rotation and companion planting. It originated early in the 20th century in reaction to rapidly changing farming practices. Certified organic agriculture accounts for globally, with over half of that total in Australia. Organic farming continues to be developed by various organizations today. Biological pest control, mixed cropping and the fostering of insect predators are encouraged. Organic standards are designed to allow the use of naturally-occurring substances while prohibiting or strictly limiting synthetic substances. ...

Fisheries
Fishery can mean either the enterprise of raising or harvesting fish and other aquatic life; or more commonly, the site where such enterprise takes place ( a.k.a. fishing ground). Commercial fisheries include wild fisheries and fish farms, both in freshwater waterbodies (about 10% of all catch) and the oceans (about 90%). About 500 million people worldwide are economically dependent on fisheries. 171 million tonnes of fish were produced in 2016, but overfishing is an increasing problem — causing declines in some populations. Because of their economic and social importance, fisheries are governed by complex fisheries management practices and legal regimes that vary widely across countries. Historically, fisheries were treated with a " first-come, first-served " approach, but recent threats by human overfishing and environmental issues have required increased regulation of fisheries to prevent conflict and increase profitable economic activity on the fishery. Modern jurisdicti ...

Marine Biology
Marine biology is the scientific study of the biology of marine life, organisms in the sea. Given that in biology many phyla, families and genera have some species that live in the sea and others that live on land, marine biology classifies species based on the environment rather than on taxonomy. A large proportion of all life on Earth lives in the ocean. The exact size of this ''large proportion'' is unknown, since many ocean species are still to be discovered. The ocean is a complex three-dimensional world covering approximately 71% of the Earth's surface. The habitats studied in marine biology include everything from the tiny layers of surface water in which organisms and abiotic items may be trapped in surface tension between the ocean and atmosphere, to the depths of the oceanic trenches, sometimes 10,000 meters or more beneath the surface of the ocean. Specific habitats include estuaries, coral reefs, kelp forests, seagrass meadows, the surrounds of seamounts and therm ...

Quebec
Quebec ( ; )According to the Canadian government, ''Québec'' (with the acute accent) is the official name in Canadian French and ''Quebec'' (without the accent) is the province's official name in Canadian English is one of the thirteen provinces and territories of Canada. It is the largest province by area and the second-largest by population. Much of the population lives in urban areas along the St. Lawrence River, between the most populous city, Montreal, and the provincial capital, Quebec City. Quebec is the home of the Québécois nation. Located in Central Canada, the province shares land borders with Ontario to the west, Newfoundland and Labrador to the northeast, New Brunswick to the southeast, and a coastal border with Nunavut; in the south it borders Maine, New Hampshire, Vermont, and New York in the United States. Between 1534 and 1763, Quebec was called ''Canada'' and was the most developed colony in New France. Following the Seven Years' War, Quebec b ...

Parasitology
Parasitology is the study of parasites, their hosts, and the relationship between them. As a biological discipline, the scope of parasitology is not determined by the organism or environment in question but by their way of life. This means it forms a synthesis of other disciplines, and draws on techniques from fields such as cell biology, bioinformatics, biochemistry, molecular biology, immunology, genetics, evolution and ecology. Fields The study of these diverse organisms means that the subject is often broken up into simpler, more focused units, which use common techniques, even if they are not studying the same organisms or diseases. Much research in parasitology falls somewhere between two or more of these definitions. In general, the study of prokaryotes falls under the field of bacteriology rather than parasitology. Medical The parasitologist F.E.G. Cox noted that "Humans are hosts to nearly 300 species of parasitic worms and over 70 species of protozoa, some derived f ...

Louis Bromfield
Louis Bromfield (December 27, 1896 – March 18, 1956) was an American writer and conservationist. A bestselling novelist in the 1920s, he reinvented himself as a farmer in the late 1930s and became one of the earliest proponents of sustainable and organic agriculture in the United States. He won the Pulitzer Prize for the Novel in 1927 for Early Autumn, founded the experimental Malabar Farm near Mansfield, Ohio, and played an important role in the early environmental movement. Life Early life Lewis Brumfield was born in Mansfield, Ohio, in 1896 to Charles Brumfield, a bank cashier and real estate speculator, and Annette Marie Coulter Brumfield, the daughter of an Ohio farmer. (Brumfield later changed the spelling of his name to "Louis Bromfield" because he thought it looked more distinguished.) As a boy, Bromfield loved working on his grandfather's farm. In 1914, he enrolled in Cornell University to study agriculture. Yet his family's deteriorating financial situation fo ...

Lake Ontario
Lake Ontario is one of the five Great Lakes of North America. It is bounded on the north, west, and southwest by the Canadian province of Ontario, and on the south and east by the U.S. state of New York. The Canada–United States border spans the centre of the lake. The Canadian cities of Toronto, Kingston, Mississauga, and Hamilton are located on the lake's northern and western shorelines, while the American city of Rochester is located on the south shore. In the Huron language, the name means "great lake". Its primary inlet is the Niagara River from Lake Erie. The last in the Great Lakes chain, Lake Ontario serves as the outlet to the Atlantic Ocean via the Saint Lawrence River, comprising the eastern end of the Saint Lawrence Seaway. The Moses-Saunders Power Dam regulates the water level of the lake. Geography Lake Ontario is the easternmost of the Great Lakes and the smallest in surface area (7,340 sq mi, 18,960 km2), although it exceeds Lake Eri ...
