Freshwater Aquatic Ecosystems
This paper will discuss freshwater aquatic ecosystem. It will identify impacts associated with agriculture, the effects that a growing human population may have on that ecosystem’s resources, including loss or harm to populations of wild species, sustainability and conservation of natural resources in freshwater aquatic ecosystem, risks and benefits of extracting or using one type of nonrenewable and one type of renewable energy resource, assess management practices for sustainability and conservation of natural resources and energy. The Fresh water ecosystems are among the earth aquatic ecosystems, which includes Lakes, ponds, rivers, streams, springs and wetlands. About 97.4% by volume is found in the

This helps promote the growth of algae. When the algae dies and decomposes, oxygen then declines. This throws off the balance of the ecosystem, which in turn, causes the elimination of many species in the freshwater ecosystem. Some of the most significantly harmful products are raw sewage and waste disposing of raw sewage into freshwater streams and lakes causes the depletion of oxygen in the water. When this occurs, it makes it difficult for living organisms to thrive. Fish tend to die when the oxygen level in water declines to a certain point. If the oxygen tends to decrease even more, it starts killing off more species as well as the eggs of different species. Because of pollution, freshwater ecosystems become unbalanced which kills the diversity of different species. Other pollutants such as toxic materials are also extremely harmful to freshwater aquatic ecosystems. When toxins such as insecticides, fertilizer, oils, pharmaceuticals, and salts pollute freshwater it becomes hazardous to humans and the species within the ecosystem. The water becomes poisonous for humans to drink as well as the animals that people eat out of the polluted water. Due to the growth in population, there is no room to store the waste that we produce. More often than not it ends up in our freshwater lakes, rivers, and streams, both intentionally and unintentionally. The growing population in the world cannot afford to lose
