Phosphates may be effective in such ways but also causes pollution issues in lakes and streams. Enrichment of phosphate can lead to eutrophication of fresh and inshore marine waters, leading to algae bloom because of the excess nutrients. Bacteria consume the algae and a bacterial bloom ensues.
Nitrogen fixing bacteria in the roots of leguminous plants reduce atmospheric nitrogen to ammonium using ATP and reduced NAD. The ammonium ions released into the soil are oxidised by nitrifying bacteria firstly to nitrite, and then to nitrate. This oxidation increases the nitrogen content in the soil which plants can use to produces many useful molecules including amino acids, proteins, DNA and ATP. The formation of these ions forms part of the ecological nitrogen cycle which plays a key role in sustaining life on this planet. Plants are the producers for an ecosystem.
The dead zone is littered with the carcasses of dead sea animals. There are 405 dead zones reported world-wide. Natural and Human Impact Dead zones can be caused by both natural and human impact on the environment. High levels of chemical nutrients (nitrogen and phosphorus) cause algae blooms to flourish. After the algae accumulate, it dies, decomposes and depletes the oxygen in the ocean creating a dead zone.
These plants do not live near the sea normally. Many plants cannot live in soil with high salt content. Salt is called an abiotic factor because it is a non-living factor. Salinity lowers their ability to absorb water and they die. We will experiment to see if beans can be grown in a soil with varying levels of salinity (salt).
This, in turn, can affect habitat quality for plants and animals that live downstream. Biodiversity may be lost if aquatic plants and animals cannot tolerate changing water conditions. When large volumes of water are pumped from a stream or river, water chemistry can change significantly with a drop in water level. Temperatures may rise and oxygen levels may drop, affecting aquatic species that don't have a wide tolerance. Biodiversity may also be reduced if invasive species, such as the zebra mussel or golden algae, are introduced into a waterbody during the drilling process.
Calcium is mostly found in sedimentary rocks in the mineral forms such as: gypsum, dolomite, and calcite. In some of the compounds, calcium is found to be soluble, but in most of the compounds found in soils, the calcium is generally insoluble. This insoluble form does not make calcium in the soil readily available to plants. The way plants actually get this calcium is due to the soil microbes that need calcium too. The microbes eat the soil compounds, therefore converting them into a form plants can actually use.
One con is that there will be many jobs at the mine, but just not nearly as many jobs that Bristol Bay employs in the salmon industry. Another, and possibly the biggest, disadvantage of building the Pebble Mine is the negative effect on the environment in Bristol Bay. Although the company managing this says that there will be a bad affect on the environment, history tells us otherwise. We can look at the Mount Polley gold mine disaster. In this environmental disaster, 10 cubic meters of water and 4.5 million cubic meters of potentially toxic slurry were spilled into virtually untouched forest, lakes and rivers.
Elevated pH can in turn ‘blind' organisms that rely on perception of dissolved chemical cues for their survival by impairing their chemosensory abilities (Figure 3) (Turner & Chislock 2010). When these dense algal blooms eventually die, microbial decomposition severely depletes dissolved oxygen, creating a hypoxic or anoxic ‘dead zone' lacking sufficient oxygen to support most organisms. Dead zones are found in many freshwater lakes including the Laurentian Great Lakes (e.g., central basin of Lake Erie; Arend et al. 2011) during the summer. Furthermore, such hypoxic events are particularly common in marine coastal environments surrounding large, nutrient-rich rivers (e.g., Mississippi River and the Gulf of Mexico; Susquehanna River and the Chesapeake Bay) and have been shown to affect more than 245,000 square kilometers in over 400 near-shore systems (Diaz & Rosenberg 2008).
The process of “liming” balances the acidity of surface waters allowing for the survival of many aquatic species and has been extensively used in Sweden to keep water at an optimum pH. However, liming is an expensive processes and has to be done repeatedly (every 3-6 years) and therefore is not considered to be a long-term cure to the broader challenges of acid deposition. • Alternative Energy Sources: Using energy sources such as wind energy, hydropower, solar energy, geothermal energy and nuclear power can offer effective electrical power alternatives instead of burning fossil fuels. • Cleaning up Exhaust Pipes and Smokestacks: Reducing the emissions of SO2 and NOx is the most important solution for acid rain. SO2 emissions are largely accounted for from burning coal while NOx emissions from automobile fossil fuel combustion.
Some studies have even shown that in some areas there was forty-six times more plastic than there was food for the animals to eat. (Conserving Now.com) The mass waves of bags could be ingested by many marine lives such as whales and many fish. The fish take all the toxins from these bags and store them inside their body. The fish is now unhealthy if this fish is later caught the toxins could be eaten by a human. An animal could also be forced to relocate from its current home because of an excess of trash that restrain the daily activities needed to survive.
