Q:

What are some ways to prevent noise pollution?

A:

Soundproofing, masking and turning off noisy devices are all ways to prevent noise pollution. Canceling sound waves with similar opposing waves can also help keep noise pollution at bay.

Soundproofing is one of the best ways to prevent noise pollution. Carpets and rugs can help keep sound from vibrating through floorboards and furniture, such as bookshelves, and heavy doors can dampen noise coming through the walls. Windows tend to let lots of sound in and out of rooms; therefore, high quality window panes and curtains can help reduce noise pollution significantly.

People can mask incoming noise pollution with more pleasant sounds. Air running through fans or water running through fountains can keep noise at bay. White noise machines can also help mask noise pollution.

Electronic devices can produce a lot of noise, and although that noise is not very loud, it can create a lot of strain. Turning off unused electronics, such as televisions or computers, helps cut back noise pollution.

People can use noise canceling devices or headphones to block noise pollution. These use signals to cancel out sound waves. Engineers can also use this technology on an industrial scale; for example, small vibrating speakers can help cancel out noise from the engines in airplane cabins and cockpits.

    How does coal affect the environment?

    A:

    Mining and using coal for power significantly impacts the environment causing pollution of the air, water table and the ground. As time goes by, the air pollution also contributes to change in the climate, creating more temperature extremes, particularly in terms of heat waves. These types of damage for the environment mean that, even though coal is cheap to mine and produce, it is definitely worth looking for other sources of power that are cleaner.

  • Q:

    What are examples of environmental degradation?

    A:

    One of the primary examples of environmental degradation is the depletion of potable water. Over 97 percent of the water on Earth is salt water. Of the remaining fresh water, almost 70 percent is in the Earth's ice caps, leaving less than one-third of the fresh water. As of 2014, one in three people face a water shortage.
