Aquaculture has been deemed as a rather controversial topic. While some view it as “bridging the gap between supply and demand” (Pauly et al., 2002), others see it as an inefficient food system reaping toxic fishes that is polluting our oceans (Harris et al., 2016). On a large scale, aquaculture could lessen the need for finding and catching wild fish for food or ornamental purposes and also help us more efficiently harvest underwater plants for uses in pharmaceuticals, nutritional supplements and other products (Harris et al., 2016). The recent 2020 FAO report on aquaculture and fisheries points to the fact…


In his book “Rivers of Power”, author Lawrence C. Smith tells a compelling tale of the history of humans, cultures, and civilizations intertwined with the history of environment, specifically rivers. Through his book the author talks about the importance of rivers that have shaped mankind, civilizations and their ever evolving yet true strength and dominance over all regions of the earth since time immortal. His aim as simple and apt as the book title is to garner acceptance of the fact that in the end, resilient and timeless rivers will prevail even when everything around them falls. A scientist, professor…


When it comes to countries with little to no access to clean drinking water, treatment of wastewater and its reuse can pave the way. The Earth’s system is one of energy flows and balances and within it the water cycle rests as a means to maintain that balance. One of the important aspects of the water cycle pertains to the production of wastewater in almost every aspect along the way. This wastewater needs collection, and treatment before being used for other purposes. The issue however is further aggravated due to an increase and prominence of water pollutants. To address this…


In her book, “Water Wars: Privatization, Pollution and Profit”, author Vandana Shiva talks about the ills of pollution and privatization of water created by the global commodification of this natural resource. Through her book she explores important issues surrounding water including inequitable access, conflicts between local communities, states and private corporations, climate change, pollution, and irrigation/farming. She insists on a democratic, community managed water market rather than the capitalistic control for water-conservation and water-sharing.

A physicist, author and an activist, Shiva Vandana presents her case with valid and sometimes controversial arguments coupled with real-life examples. She focuses on many international…


As a laboratory biologist performing environmental toxicology testing and research, my work focuses on the connection between water chemistry and the environmental effects of contaminants. I help investigate the toxicity of wastewater from several sewage treatment plants and effluents from various pulp and paper mills, and metal mines. Working in an ecotoxicology lab setting and I love that I get to culture and interact with various freshwater and marine species such as Ceriodaphnia dubia (water flea), Daphnia magna (…cousins of water flea), Lemna minor (duckweed), Pseudokirchneriella subcapitata (green algae) etc. The work entails producing reproducible and robust results that help…
