Climate Change and Human/Wildlife Health: Direct and Indirect Effects and The Greenhouse Effect By Emanuel Picon Climate change effects are activities that threaten human and animal health, such as habitat destruction and urbanization, and pollution. These human activities directly affect the ecosystem and indirectly affect human and animal health as well. Climate change can also be seen in physical and climate events, such as the El Niño and solar radiation that have large effects on the Earth’s climate and in humans and animals. A lot of evidence exists for climate bad effects on wildlife. Factors of concern, such as ecosystem composition and pathogen virulence, are said to be related to climate changes.
Proximity to large concentrations of people is another important factor contributing to ecosystem vulnerability. As populations grow so does the demand fro land. Urban, industrial and agricultural land uses destroy natural ecosystems; therefor the
“While [hydraulic fracturing] can help provide energy for America's future, it also poses a new dangerous threat to wildlife and the environment. Toxic chemicals are used during fracking that can infiltrate and contaminate habitat, waterways, and even the drinking water that people and wildlife depend on” (1996-2013). Evidently, “some opponents of oil and natural gas production claim that fracking has serious environmental consequences. The truth is, while all development has challenges, hydraulic fracturing technology has a strong environmental track record and is employed under close supervision by state, local and federal regulators. Studies by the Environmental Protection Agency (EPA) and the Ground Water Protection Council (GWPC) have confirmed no direct link between hydraulic fracturing operations and groundwater contamination.
The largest human cause of dead zones is nutrient run off from abundant use of fertilizers, animal waste and sewage. The runoff is a bi-product of our agribusiness, farming practices and growing population. Before immense land development the wetlands acted as a natural barrier and filter. The runoff would be depleted in the soil by the plants before it could reach the rivers and ocean. Human commercial activity and land development have destroyed the natural shield of the wetlands.
This complex ecosystem is both an extraordinary geological and ecological feature of Florida and encompasses a historic, social, economic, and environmental significance. The IRL is a network of people, places, and natural resources that are inter-dependent upon each other. Unfortunately, the primary threat to this unique ecosystem comes from human population growth as well as coast-line developers. The storm water and sewage run-offs pose significant pollution problems to the ecosystems survival. Today, scientists, and resource managers are concerned about the future of the lagoon, including declines in quality of the water, loss of habitat, biological diversity, invasive species, diminishing fisheries, and the declining of the ecosystem’s health.
Jennifer Holder Unit 9: The principles of infection prevention and control. Understand the roles and responsibilities in the prevention and control of infection: 1.1 Employee's are responsible for numerous things in relation to the control and prevention of infection. It is the employee's responsibility to ensure that they protect themselves, colleagues, patients and visitors from infection by adhering to infection control policies. Employee's should always wear the correct personal protective equipment (PPE) for the duty in which they are undertaking and ensuring proper disposal of this PPE as well as infective material or other clinical waste. Ensuring that they have good hand hygeine techniques is also very important when it comes to the prevention and control of infection.
Runoff Quality of the water flowing from the a\land is critical to the reef’s health. The ones near the mainland are the most damaged because of human activities. The land use activities near the coast increases freshwater runoff and the build up of silt. As more land is eroded by human activities the runoff increases destroying the vegetation. Fertilisers, sewage and pollutants can have direct impact on the coral reefs.
1. Introduce the topic and identify the global reasons for water shortages. Water shortage is one of the key ecological issues of our time. Distinguish some real reason for water shortage and portray two results. Water is considered an essential element for the human being, animals, plants and all other creatures on the earth.
Droughts are likely to become more widespread, while increases in heavy precipitation events would produce more flooding. Water quality is important for ecosystems, human health and sanitation, agriculture, and other purposes. Increases in temperature, changes in precipitation, sea level rise, and extreme events could diminish water quality in many regions. In particular, saltwater from rising sea level and storm surges threaten water supplies in coastal areas and on small islands. Additionally, increasing water temperatures can cause algal blooms and potentially increase bacteria in water bodies.
Unfortunately, humans are the most polluting species on the planet. Pollution occurs at different levels and it doesn't just impact our planet; it impacts all species, including mankind, who dwell on it. We pollute water with chemicals and waste products from factories.Water pollution has led to a decrease in the number of various aquatic animals. Several aquatic life forms are on the verge of extinction. Vehicles, trains and planes emit toxic gases, creating air pollution.
