Nutrient pollution coming from agricultural runoff and other fertilizers allows for the growth of species that upset the balance of the ecosystem such as Cattail, harmful algae bloom, and duckweed. The sulfur in the agricultural fertilizers leads to accumulation of toxic mercury in fish, birds, and mammals. Also, exotic animals or invasive species displaced native and threatens to disrupt the ecosystem balance. The purpose of this experiment is to determine how the water quality affects the Everglades ecosystem and how water pollution impacts different species. Urbanization is a big threat that contributes to poor water quality in water pollution.
Mining the hydrothermal vents could make it so that some very bad things could happen to our earth. Mining is very bad idea until we finish all of the studies about hydrothermal vents because very bad things could happen to fish and the communities nearby the mining. First, The vents are used as homes for species. Mining could wipe out all of the yet to be discovered species. Mining will pollute the water and let out toxins that can kill species and communities near by.
The huge numbers of algae can block the pores on sponges, block light penetration through to the zooxanthellae living within the corals, and decrease the its resistance to coral diseases. Pollutions such as sewage outflow, the use of fertilizers from both urban and agricultural have huge impacts on coral reefs. These wastes contain high concentration of nitrogen and phosphorus which are toxic to the reef ecosystem. The large content of phosphorus and nitrogen from animal waste and fertilizers are lethal to coral polyps. The excess nutrients may induce pathogen and provide the elements required by the pathogen to proliferate or become directly toxic to the coral making them more susceptible to the disease.The imbalance in the exchange of nutrients between the zooxanthellae and the host coral reduces light penetration to the reef due to nutrient-stimulated phytoplankton growth, and, most harmful of all, may bring about proliferation of seaweeds (Dubinsky, 1996).Nevertheless, the study had discovered that the coral capable to recover and revive once the nutrients supplies stopped.
Companies producing products must get their materials from somewhere. Often if they must mine these materials, it’s done in a poor country where they can get away with unethical working conditions. Unethical working conditions are described as exposing workers to hazardous conditions (the mine could collapse, they breathe in toxic chemicals, etc. ), Many mining chains use child labor and put these children at risk, also chemicals released from mining cobalt get put into the atmosphere and are eventually absorbed into the soil or water around the mining site. It’s important for companies to prove that their product is or isn’t ethical because companies should be transparent about how their products are made.
Endangered specie populations in Mexico Introduction: Humans have drastically modified wildlife by polluting the earth we live in. Pollution is one of the major insidious threats to the environment, it ranges from obvious action, such as dumping in rivers and lakes to sprayed undetected chemicals. However, if the effect is permanent or short term the outcome does not change. Pollution changes the balance of ecosystems which causes numerous animals to become extinct. For example, the Bald eagle, peregrine falcon, and brown pelican all became endangered or extinct prior to scientists finding out that the chemical DDT, a chemical used largely in the United States as a pesticide.
The first and foremost is the oil spillage in the ocean which leads to ocean acidification. This brings a huge threat towards the environment and the marine wildlife. Oil operation in sea bed often requires drilling fluids such as mud which are used to inject into the wellbore to lubricate the drilling bit. These devastating effects of numerous oil spills on the surface of the ocean could bring a long term environmental effect to the coastal areas as well as to the sea bed. Besides, drilling mud which contains toxic substances like benzene, zinc, arsenic, radioactive materials, and other contaminants are used to lubricate drill bits and maintain the pressure in the drill.
Escherichia Coli aka E. Coli, has the ability to absorb and contain uranium. Although there are strains of it that can cause disease, this can handle nuclear waste. While it would be good if this bacteria did disappear, nuclear waste spills could get out of hand. For example, if a spill had gone into the ocean, this could potentially get into our water supply and harm marine animals. By harming the marine animals, they could eventually mutate or become harmful to us when consumed.
As more and more water is becoming contaminated with pesticides and chemicals, it is becoming even harder to stop the corals from dying. Thankfully, there are solutions that can help restore the Great Barrier Reef. Just as there are several causes to the habitat change of the Great Barrier Reef, there are ways to put the progressing depletion to a stop. One effective solution is to cut farm pollution, or at least keep it from the oceans. Using organic fertilizers instead of harmful chemicals can keep the coral’s water fresh from the dangerous pesticides.
Water and sand are inserted into the shale formations at high pressures in order to make cracks in the shale that helps recover natural gases from below the Earth’s surface. Despite the fact that it does some benefit for the economy, fracking should be abolished as it causes health risks due to pollution, over consumes resources, and causes controversy over both human and animal habitats. Fracking causes pollution, and in this manner
Some of the consequences of exceeding the environmental capacity include strain on already scarce resources such as water, food, energy and natural habitat areas and also unchecked tourism management may lead to natural disasters like soil erosion, Increased pollution and waste, deforestation, Increased pressure on endangered species of animals and plants and as well as loss of biodiversity. Mass tourism may deplete the socio-cultural traditions and authenticity of host community by introducing foreign elements which are in conflict with cultural, historical, and religious heritage of the community.
