The Benefits of Algae

How often also does a human use or eat algae in his daily life? When most people think of algae, they probably think of something that is slimy, gross, and dirty. Algae may irritate people because it grows in unwanted places like swimming pools and boats. Algae can be toxic and it is slimy, but algae benefits people in all aspects of life. Humans obtain algin from algae to help make ice cream, pudding, face cream, and shoe polish. Algae is present in hamburgers, yoghurt, and cakes. Algae also helps make explosives, insulation, and paint. Algae produces most of the oxygen that animals breathe and without it the world would suffocate. Also, according to Helen Challand, "It is now believed that the oil and gas formed millions of years ago in the ground were created by algae" (20). …show more content…

The Aztecs have proven that this idea is possible. Lake Texcoco flowed near the Aztec civilization. The Aztecs disposed of their waste in the lake. The human waste added nitrogen to the water. The nitrogen helped algae to grow, and then the algae performed photosynthesis. Photosynthesis gives off oxygen, and oxygen purifies polluted water. The Aztec's also abstracted the algae from the lake and used it for food. Certain types of algae like red and green algae are edible. Many cultures have eaten seaweed for centuries. Wendy O'Leary Dunn states, "They think of seaweed as a vegetable and eat it as we eat broccoli or spinach" (18). Therefore, when humans dispose of their waste in bodies of water, they help algae grow. Then, the algae cleans the water and they can eat the

    This alga has no predators that we know of for sure right now, but most likely this alga is a part of herbivorous marine animals', like sea urchins, sea turtles, and small fish, diets. Extracts of this alga, and relatives, are used in certain medicines, shampoos, and skin lotions, and is claimed to aid in skin health and support bones and cartilage. However the FDA has not reputed these claims. A 2009 study also shows that extracts from this alga are very effective as fertilizers and may also work as an antifungal. The antifungal side of these algae is part of what makes this an effective fertilizer: because the extracts also work as antifungals, they are able to slow down the growth of fungi that may harm the plants.

  • Question and Answer - Trophic Levels

    1062 Words  | 3 Pages

    Once that step is determined, scientists will assign that group of species to a trophic level; to either the primary producers, primary consumers, secondary consumers, or the tertiary consumers. The bottom of the chain and the trophic level that depends upon by all others is the primary producers. These primary producers consist of autotrophs, which are capable of deriving their food and energy source without consuming organisms or substances taken from other organisms. In the Arctic lake of Alaska, one of it’s primary producers consists of aquatic plants and algae. These aquatic and algae contain chlorophyll, which means that they can use light energy from the sun to synthesize glucose and other organic compounds, that they can use for cellular respiration and building material for growth.

    This toxic algae has been proliferating extremely rapidly over the past years. One of the reasons of this is warming waters. Warming waters is a phenomenon that has been increasing significantly over the past 20 years. The main reason that this is happening is because of global warming: Since planet Earth gets warmer, its oceans get warmer too.

    Some plants live in conditions where the spectral quality of light may be different to that received by plants living on the land. Algae which live in surface waters tend to be green and contain more or less the same pigments as land plants since they exist under similar light conditions. Algae living lower in the water receive more blue light than red because red light has a relatively long wavelength and cannot penetrate water as well as blue light which has a shorter wavelength and more energy than red light. Brown algae, which may be found deeper in the water than green algae, have combinations of pigments which enable them to

    Introduction on Water It covers 70% of our planet, makes up 75% of our body, it is necessary for survival and it is declining at a rapid rate (http://www.sscwd.org). It is water. Unfortunately, clean water is rare, almost 1 billion people in developing countries do not have access to water everyday. “Yet, we take it for granted, we waste it, and we even pay too much to drink it from little plastic bottles” (The Water Project). Use of earth’s natural resources should be seen as prosperity, although it is taken for granted, every aspect of daily life revolves around the environment, forcing water conservation to be necessary for future on this planet.

    The agriculture industries have affected the marine life due to eutrophication. Eutrophication occurs when human activity water because of the chemicals, nitrogen and phosphorus which run off into the water. Eutrophication results in algal bloom. An algal bloom forms when lots of nitrogen and phosphorus are set inside a body of water which results in an excess amount of algae in lakes, oceans, or streams. The waters can not take in a lot of algae because in can affect the habitat of the animals. It can also affect the population of the sea animals.

    Although we do not eat them directly, as humans we eat other animals that do such as the Largemouth Bass, which eat Daphnia when it is young. “Daphnia are very important because they take nutrients from algae into their bodies and pass those nutrients on to their predators. As other predators eat the fish or other animals which ate the Daphnia, the nutrients get passed on again.”

  • Benefits Of Algae

    It is believed that the world's supply of oil will last until about 2040. If you think about it, that’s not too far in the distance future. Oil is running out fast and we need to think of an alternate energy source. When we burn oil, we release carbon dioxide into the air which causes the earth’s climate to warm; a temperature rise of 3.6 degrees Fahrenheit could have serious if not devastating consequences. In the United States alone 60 percent of each person’s carbon footprint comes from the goods they buy, while the other 40 percent comes from their energy use at home, driving, and flying. That totals out to be about 10 billion tons a year. There are other energy sources but let’s think about the environmental and energy benefits of algae biofuel. Algae was first explored as a fuel alternative in 1978. Gas prices had skyrocketed, and the government was looking to help ease the crisis. The Aquatic Species Program run by the National Renewable Energy Laboratory, researched high oil-output algae for biofuel. After testing 3,000 types of algae, the program concluded that the algae, if...

  • The Aponic System: The Benefits Of The Aquaponics System

    1853 Words  | 4 Pages

    Aquaponics systems are the combination of aquaculture (raising fish in a tank) and hydroponics (growing of plants in a soil-less environment) that facilitates the growth of the fish and plants simultaneously in one integrated system. The waste produced by the fish would provide a source of nutrition for the growing plants and the plants naturally filter the water in which the fish live in. Another process involved in the aquaponics system is the participation of microbes (nitrifying bacteria) and composting red worms that flourish in the growing media. They convert the ammonia present in the fish waste into nitrites, then into nitrates and the solids into vermicompost that serves are food for the plants. By combining both aquaculture and hydroponics, aquaponics capitalizes on the benefits of both and eliminates the downsides associated with them.

  • The Effects of Saltwater on Algae

    650 Words  | 2 Pages

    This experiment was used to see the effect of salt water on the algae in the freshwater tables. The effect of salt water on algae will make the algae decrease in number. The algae were used as an indicator organism to give an idea of pollution concentrations. (Colgan, 33) Salt water can cause many problems if the salt water should enter the freshwater ways. This salt water can contaminate the aquifers and drinking waters of the world. This idea is backed up in Spatafora’s saltwater intrusion paper “When this occurs, it will move the saltwater freshwater interface inland, resulting in a higher saline concentration in the aquifers' water, rendering it useless for human consumption, unless it is treated.”(Spatafora, 2008) Not only can the saltwater effect the drinking water this water can also not be used for irrigation as seen in F. Lugoli’s article about the contamination of southeastern Salento’s groundwater “The results indicated widespread pollution from salt and microbial contamination. Contamination from faecal microorganisms posed a significant risk of human infection in 100% of samples. Furthermore, the water was unsuitable even for irrigation in a high percentage of cases (31.8%), which is of considerable significance given that agriculture is one of the most important economic activities in the area under study.”(Lugoli, 2010) The salt water can also kill the plants, algae, and ultimately the animals that use that water for water and food. The rising amounts of saltwater can cause plants to die as seen in Winn’s Saltwater Intrusion and Morphological Change at the Mouth of the East Alligator River, Northern Territory article “Significant morphological change has occurred since 1950, with the tidal creek extending 4 km inlan...

  • Aquaponics Advantages And Disadvantages

    880 Words  | 2 Pages

    Growing food with Aquaponics is more efficient than growing food the traditional soil garden way. In a typical soil garden, growers end up spending hours of their time doing back breaking work on their garden, but not anymore, with Aquaponics the need for any tilling, digging, or weeding is eliminated. Aquaponics combines Aquaculture (Raising fish in tanks), and Hydroponics (Growing plants without soil). The outcome is a working system that provides plants with all the nutrients they need, while using a minimum of space, effort, water, fertilizers, and pesticides. Aquaponics allows farmers to use up to 90% less water than normal farming would use, so instead of watering your soil and having the majority of your water either lost by run off or evaporated by the sun, the water is recycled repeatedly through the system saving farmers hundreds of dollars on their monthly water bills. Also when growing with Aquaponics, much more food can be produced in a smaller space, in some cases growers have produced around twenty times the amount of produce in the same area a soil garden would. In addition, with the closed, controlled environment of the system, the need for the use of any pesticides a basically eliminated. Finally, Aquaponics enables growers to grow bigger, better and more quality produce.

  • Case Study of Waste Water Treatment Plants

    1046 Words  | 3 Pages

    A precise system, of which must be compliant according to government standards, is critical to maintain low levels of waste that are returned to neighboring water systems after treatment. Phase one of waste water treatment begins in the home, local businesses and community. Waste water from these buildings and surrounding areas travel through a pipe, or sewer which is sloped downward, and with the assistance of gravity, travels toward the waste water treatment plant. However, in larger communities or communities with unevenly leveled terrain, waste water cannot keep getting deeper to rely on gravity to transport the waste water and must be pumped up with the assistance of a lift station so it may continue to travel to the water treatment plant. Once the waste water arrives at the waste water treatment plant, the first step is the removal of large debris such as diapers, underwear or other non-biological substances or products.

  • The Biogen Cycle: The Nitrogen Cycle And The Cycle Of Life

    1574 Words  | 4 Pages

    Humans often take the water cycle for granted and assume that fresh water will always be available for drinking, cooking, farming, etc. Unfortunately, the ways in which society uses water is contributing to the reduction in fresh water available for human use. First of all, the use of hydroelectric power, though a clean source of energy, is negatively affecting the ecosystems in which the plant is stationed. The waterway must be dammed in order to maximize the potential energy of the water, but this often affects the function of the waterway upstream and downstream. For example, the build-up of water above the dam may create a lake where silt can build up while a lack of water below the dam eliminates habitats. Moreover, plants and aquatic animals that previously inhabited the waterway “may find themselves with too much or too little water, and migrating fish cannot get through the dams” (Humans and the water cycle). Not only does hydroelectricity disrupt the water cycle, but irrigation does as well. “Irrigation is the artificial watering of land that does not get enough water through rainfall” (Humans and the water cycle). Most countries that use irrigation have dry land or they require more water to grow more plants for their increasing population. The issue with irrigation is that it removes relatively clean water from its natural source and essentially pollutes it. The fertilizer in
