Quiz 15: Air Polution,climate Change,and Ozone Depletion

Environmental Science

Yes would take an initiative for action when glaciers meet this result in increasing the sea level. They have the capability to destroy people and their habitat. It is important to generate a feedback loop that leads to increase the climatic changes and their effects. As due to lack of reflective capacity of an ice more heat is absorbed by landscape and result to enhance this problem.

Radon is a colorless, odorless and a chemically inert gas, which mixes with air. It is found in both soil and water, where the concentration of radon depends on the type of soil/water. The average radon levels outdoor are about 0.2 - 0.7 pCi/L. There are several methods to reduce radon exposure at home. Most of these are temporary and need to be used in combination with other mitigation measures: • Sealing the cracks and other openings in the walls and its edges limits the flow of radon into home and also reduces the loss of conditioned air, thereby increasing the efficiency of other radon reduction techniques. • House pressurization is maintained by a fan by blowing air into the basement or living area from either upstairs or outside. The doors and windows at the lowest level must remain closed to maintain enough pressure to keep radon out (except for normal entry and exit). • Increasing the natural ventilation in house by opening windows on the lower floors. This causes mixing of radon with outside air and can result in temporarily reduced radon levels. • To increase ventilation, a heat recovery ventilator (HRV) can be installed. It will increase ventilation in the house using the heated or cooled air being used to warm or cool the incoming air.

Each person's carbon footprint will vary. People who live in the city will rely more on public modes of transportation while people who live in the suburbs will rely on automobiles. img
