Another leading cause of pollution in Lake Huron is air pollution. Past environmental studies have shown over three million kilograms of carcinogens polluting the air (Statistics 2003). Currently studies show the working group in Lake Huron have clean up day to help promote clean air (Statistics 2009). Other contributing causes to the pollution in Lake Huron are fertilizers which have caused major algae blooms, causing an imbalance in nutrients, a collapse in the salmon fishery, and chemicals from pesticides. Fish stocks have significantly declined due to the increased pollutants (Harvey
Over the past 43 years, Michigan has been the second-fastest-warming state in the country, followed by Minnesota and Wisconsin (Kalish, 2012). From 193 to 2011 the annual ice coverage as declined drastically. Reduced ice cover can have large impacts on the health of Lake Huron. Increased light penetration promotes algae growth and the survival of invasive species. Without ice and snow coverage, the lakes suffer from water loss due to increased evaporation.
Much controversy came about due to the construction of the Glen Canyon Dam as part of the Colorado River Compact, which aimed to 'ensure through water storage the delivery of sufficient water to the lower basin during years of drought, so as to allow the upper basin to better utilize its allocation of river flow' as proposed by The USBR (United States Bureau of Reclamation). The construction of the dam led to the creation of Lake Powell, a reservoir which brought in its own revenue through tourism and recreational activities such as jet-skiing. The Glen Canyon Dam is also major generator of the Colorado River Storage Project, comprising 75-85% of total CRSP generation. However, environmentalists such as the Sierra Club (a large-scale environmental
But if my opponents did any research, they would realize that there is plenty of evidence to show that global warming is a real threat to this earth. In his essay “Now Or Never”, Bill McKibben writes: Consider hydrology, for instance. Warm air holds more water vapor the cold air, so there is an increase in evaporation in dry areas, and hence more drought—something that has been documented on every continent. Once that water is in the atmosphere, it’s going to come down someone—and indeed we have seen the most dramatic flooding ever recorded in recent years. In 1998, 300 million humans, one in twenty of us, had to leave their homes for a week, and month, a year, forever because of rising waters.
With the lack of rain, lakes dropped five feet, and the topsoil that took years to build was blowing with every gust of wind. The dust was so thick that black clouds began to blot out the sun and drift like snow (Ganzel, 2003). The second factor which contributed to the United States growth and development is the population increase from the Gold Rush. Estimates indicate that half
On the other hand in California in 1996-7 they were experiencing sub-tropical storms, it had been the wettest December in a while. Furthermore rail was falling at a high elevation causing snow of mountains to melt and increasing further water. Impacts included 23000 homes and buildings destroyed, 1200 evacuated and caused $2 billion in damage. This is less than the Philippines because they had some protection from levees on the Sacramento River however they did fail, due to the already saturated land. However it reduced the amount of water but also they had a bit of warning and many people got evacuated in time.
Recognized by many as the “smeltdown in the Delta,” the extinction trajectory of delta smelt, has left the once-abundant species in critical condition due to record-high water diversions, pollutants, and harmful nonnative species that thrive in the damaged delta habitat. The delta smelt is semelparous, living one year and dying after its first spawning. Delta smelt spawning occurs in spring in river channels and tidally influenced backwater sloughs upstream of the mixing zone where saltwater meets freshwater. This shift in the species center of abundance arises from the fact that while the delta smelt is a saltwater tolerant species, it is seldom found where sea
It was literally a dumping ground and it even caught on fire a few times due to the toxic wastes. The phosphorus levels in Lake Erie are increasing due to the pollution causing harm to the fishes that reside in it. In 2014, Lake Erie had so much algae from pollution that it caused the City of Toledo to be left without fresh water. This algae was caused by the excessive amount of phosphorus in the lake. This excessive amount of Phosphorus is caused when the fertilizer is dumped into the lake by farmers.
The Colorado River’s source starts in the Rocky Mountains and runs 1,500 miles South, through America and in to Mexico. It is the economic, cultural and social backbone of South West America. In the 1920’s, Western states began dividing and separating the river’s water to build dams and supply for rapidly growing places like San Diego, Phoenix and LA. The river is now responsible for serving approximately 30 million people spread over 7 states in the USA and 2 states in Mexico. It also provides water for 3.5 million acres of cropland.
