Clean Water Environment Essay

Many systems for humans would not function without clean water, such as: water supply, sanitation, agriculture, and health, which are dependent on fresh water supply.
We also often get our drinking water from lakes and rivers and with healthier water systems come a healthier food chain. This is because all animals and plants depend upon the water on the earth. There is a connection between the changes in fish habitations and the composition of species in these habitats (Komatsu, Fukushima, and Harasawa, 2007), and healthy water systems. Biodiversity is threatened by the changes happening in climates largely with loss of ideal habitats. Sea levels and temperatures rise, and with this relocation of plants, animals, and humans will be forced …show more content…

When fresh water is heated through global warming, air bubbles start to form and the water evaporates, or starts to steam, therefore losing the dissolved oxygen into the atmosphere. The amount of oxygen that dissolves in water can vary through daily and seasonal cycles, and can decrease with higher temperature, dissolved salt content, and elevation of the body of water. Surface water, near the water-air boundary and with adequate light for photosynthesis, is generally saturated or even supersaturated with oxygen; this is because dissolved oxygen comes from the atmosphere and from photosynthesis by aquatic plants. However, the surface water is typically too warm for the majority of aquatic life and yet there is not enough dissolved oxygen that even if the water were circulated well, there would not be enough for all of the aquatic organisms and the organic decay that uses a large of oxygen. Summers that are hotter with less rainfall could increase the risk of deoxygenation. This could be amplified even further where plant growth has been fortified by higher water temperatures and an abundance of nutrient supply, leading to low levels of oxygen and possible threats to the aquaculture of the area (Whitehead, Wilby, Battarbee, Kernan, and Wade). All forms of aquatic life use dissolved oxygen in surface water; therefore, this component is typically another measure to assess the "health" of lakes and streams. If dissolved …show more content…

The water temperatures that are important in all biological systems affect aquatic environments; this includes the organic chemistry, and the growth and death rates of aquatic life. Warmer climates and larger amounts of nutrient concentrations amass competition between phytoplankton and cyanobacteria in favour of cyanobacteria, which disrupts the balance of the aquaculture. (Depla et al, 2009). Plankton are a crucial source of food for larger animals. Phytoplankton are the first link in the food chain. They are known as primary producers because they produce the first forms of food. Plankton disappearing would certainly affect the food chain, but there 's another problem if the phytoplankton were to disappear: they provide the majority of the atmosphere 's oxygen. With invasive species on the rise important elements of aquatic ecosystems are being diminished and biodiversity is threatened. Biological ecosystems are moving into waters that are unnatural because of climate change, this causes over population and competition that make for an unhealthy environment and bionetwork. Aquatic ecosystems have a specific capacity of buffering, however once these buffering systems hits their peak capability, significant, and often rapid ecosystem changes that affect water quality can occur (Murdoch, 2000). The complexity of aquatic ecosystems and the
