What are the Risks of Scuba Diving? Diving does entail some risk. Not to frighten you, but these risks include decompression sickness (DCS, the “bends”), arterial air embolism, and of course drowning. There are also effects of diving, such as nitrogen narcosis, that can contribute to the cause of these problems.

Hazards at work may include: noisy machinery, a moving forklift, chemicals, electricity, working at heights, a repetitive job, bullying and violence at the workplace. Risk is the possibility that harm (death, injury or illness) might occur when exposed to a hazard.

Extraction processes can generate air and water pollution, and harm local communities. Transporting fuels from the mine or well can cause air pollution and lead to serious accidents and spills. When the fuels are burned, they emit toxins and global warming emissions.

One of the incredible advantages to fracking is that it can recover both crude oil and natural gas from shale deposits in unprecedented amounts. ... By aiding in the transition from coal to natural gas, fracking has actually improved emissions more than many other sustainable energy initiatives.

There are various impacts of combustion on the environment, these impacts can be caused by; Gas leaks, oil spillage, noise and air pollution. Incomplete combustion of hydrocarbons also results in carbon monoxide pollution. An odorless, colorless gas, carbon monoxide can be harmful to both the environment and to people.

Natural and man-made hazards include, for instance, droughts, desertification, floods, fires, earthquakes and dispersion of radioactive gases in the atmosphere. They have significant social, environmental and economic impacts.

Hydraulic fracturing, or “fracking”, is the process of drilling and injecting fluid into the ground at a high pressure in order to fracture shale rocks to release natural gas inside. Horizontal drilling is a drilling process in which the well is turned horizontally at a depth.

Non- renewable energy can be dangerous and cause respiratory problems to humans because sources like fossil fuels emit gases such as carbon monoxide. 3. Sources like coal, oil and natural gas release a large amount of carbon dioxide when burnt.
