There will also be a handout to go along with the presentation that will consist of a list of Outstanding Resource Waters and CAFOs in the Fox Valley Territory.
Wetlands: physiography, biological diversity and trophic interdependence SuvradeepMandal1
Wetlands are diverse, productive ecosystems of ecological and economic value. It plays a critical role in maintaining many natural cycles and supporting a wide range of biodiversity
This presentation looks at water hyacinth with respect to Lake victoria. It explores the biological classification, the origin, factors for its flourishing and its detrimental effects. It further explores the various control measures and the economic uses of this floating water weed.
brackish water and mangrove environment in BangladeshMD. ZANE ALAM
Brackish water or briny water is water that has more salinity than fresh water, but not as much as seawater. It may result from mixing of seawater with fresh water, as in estuaries, or it may occur in brackish fossil aquifers. The word comes from the Middle Dutch root "brak". Certain human activities can produce brackish water, in particular civil engineering projects such as dikes and the flooding of coastal marshland to produce brackish water pools for freshwater prawn farming. Brackish water is also the primary waste product of the salinity gradient power process. Because brackish water is hostile to the growth of most terrestrial plant species, without appropriate management it is damaging to the environment.
Modern developments in transport technology are from two levels; one is from an understanding of internal physiological mechanisms of the fish and the optimal requirements, ensuring maximum survival of fish under transport and the other is from a study of the environmental parameters of the medium in which fish are transported. Under anaesthesia fish can be transported without water even, provided the skin and gills are kept moist under low temperature. The cryopreservation of fish sperm for use at any convenient time can be referred to here, though this would concern seed production more directly than live seed transport.
Bangladesh is endowed by three principal river systems: the rivers Brahmaputra (Jamuna), Ganges (Padma), and Meghna. In the agro-based economy of Bangladesh,fisheries play an important role in nutrition, employment and foreign exchange earnings, contributing 4.37% to GDP, 2.01% to export earning, 60% to animal protein intake, in addition to providing 1.4 million people full time and 11 million part time employment. In 2012-2013 the total production of fish in Bangladesh was 3.41 million tons. About 82.73% of the fish production (2.82 million tons) comes from the inland fresh water resources and 17.27% from marine resources (0.58 million tons). Inland fisheries resources are broadly classified into inland open waters and inland closed waters which comprises the area of 3.91 million ha and 0.78 million ha contributing fish production over 1.85 million tons (54.54%) and 0.96 million tons (28.19%) respectively. Among the
4.69 million ha of inland open water resources, the major proportion consists of floodplains with an area of 2.8 million ha contributing 0.77 million tons of fish in 20012-13.
Seasonal floodplains are water bodies that retain water for 5-6 months during which they are suitable to grow fish and other aquatic animals. Recent studies have revealed that, if
25% of the 2.8 million ha can be brought under community management, calculating 50% to be accessible, then 6.7 million people would be benefited including 2.7 million
landless people. Out of 2.8 million ha of medium and deep-flooded areas, about 1.5 million ha are estimated to be suitable for community based fish culture. If 50% of accessible water of these areas is taken under aquaculture and management practices, then annual fish production will be increased 4 to 5 times over the existing production .
Climate change effect can be mitigated by investing in quality infrastructure (solar-driven system) and using natural fibre (water weed) to produce biodegradables.

The Aggregate Resource Act is being revised in Ontario. Here is the info I submitted to the ARA committee July 5th 2012 speaking of how aggregates put agricultural sectors, and water supplies and our GDP at risk.
This presentation briefly covers human impacts on wildlife such as habitat destruction and pollution, along with the importance and benefits of wetlands. Most of the imformation leads into several Pennsylvania species labeled as threatened or endangered. Being that my main interests are in snakes, I throw additional color photos of a few PA snakes into the end of the presentation. Hope you enjoy.
Water Resources and Water PollutionLife on planet Earth would be.docxmelbruce90096
Water Resources and Water Pollution
Life on planet Earth would be impossible without water. All life forms, from unicellular bacteria to multicellular plants and animals, contain water. Humans are composed of approximately 60 percent water by body weight and we depend on water, not only for our survival, but for our convenience: We drink it, cook with it, wash in it, travel on it, and use an enormous amount of it for agriculture, manufacturing, mining, energy, production, and waste disposal. Though 71% of the Earth’s surface is covered in water, only 0.024% of the overall water supply is available as liquid freshwater that is easily accessible. It is one of the most poorly managed resources, easily wasted and often polluted. The available freshwater is collected, purified and distributed in the hydrologic cycle, but this cycle is easily interrupted by overloading with pollution, reducing wetlands, and reducing forests.
We get water from groundwater and surface water. Groundwateris water that seeps into the ground between spaces in soil and gravel until it reaches impenetrable bedrock. One of the most important sources of freshwater. The top of the groundwater zone that moves up and down based on weather is the water table. The water table drops in level when humans remove water at a faster rate than it is replenished. Surface wateris freshwater from precipitation and melted snow that flows into lakes, wetlands, rivers, and eventually into the oceans.
Water shortages are caused by many factors including dry climate and drought. In some places, the human population uses water at a faster rate than the water is replenished. 30% of the Earth’s land mass now experiences severe or extreme drought and 1 billion people lacked regular access to clean water for drinking, cooking, and washing.
Water Supplies
Aquifers, underground water supplies, are renewable as long as the groundwater doesn’t become contaminated and withdrawn too quickly. Most aquifers around the world, and in the largest food producing countries, are being used up quicker than their rate of replenishment. Dam and reservoir systems are used to capture and hold runoff water. The collected water can be released at need to control flooding, supply water for farming and cities, and to produce electricity. The use of dams and reservoirs has increased the amount of reliable surface runoff by one-third. Unfortunately, these systems also displace people, flood productive lands, and disrupt the ecological services rivers provide.
Tunnels, aqueducts, and underground pipes transfer runoff from dams and reservoirs to water-poor areas. These transfer systems can be wasteful and environmentally harmful by shrinking the water source as more is transferred to water-poor areas. Another option for freshwater is desalinization which involves removing salts from ocean or brackish water. Usually desalinization costs a lot because of the energy required; it also kills many marine organisms and creates salty.
PA needs to draft a strong Watershed Implementation Plan (WIP), not for the sake of the Chesapeake, but for the health of the Susquehanna. In January, the PA Fish and Boat Commission came out with a resolution that points out that the water quality of the Susquehanna is the cause for the demise of the Susquehanna bass fishery. Please watch this movie of the powerpoint that I presented in front of PA DEP Secretary Hanger and PA Department of Agriculture Secretary Redding (9/1/2010).
10. 1 dairy cow creates as much polluted wastewater as 18 people CAFO =700 dairy cows ~2,500 feeder pigs ~55,000 turkeys ~125,000 chickens (other than hens that lay eggs) Farms with 1,000 animal units need a water protection permit. [1 dairy cow= 1.4 animal units]
12. Wisconsin currently has 194 CAFOs Many have the potential to pollute nearby water & land resources, Decrease Property Values, And impact the quality of life for those living nearby
