  • What are the problems with burying waste in landfill sites?

    Q: What are the problems with burying waste in landfill sites?

    A: Burying waste in landfills creates offensive odors and potentially dangerous gases that are capable of moving through soil into nearby buildings. The most harmful gases generated in landfills are methane, carbon dioxide, ammonia and sulfides. Methane is flammable, while carbon dioxide is known to move into buildings and displace oxygen.

  • Why are aerosol cans bad for the environment?

    Q: Why are aerosol cans bad for the environment?

    A: A well-known campaign against chlorofluorocarbons in aerosols in the 1970s led to continued association of the chemical with aerosol sprays. However, this issue was entirely resolved, and aerosols are no longer a threat to the ozone layer. However, they are still not beneficial to the environment as they are one of many products that contribute to global warming and smog problems.

  • Q: What are the effects of pollution on the ozone layer?

    A: One of the greatest and most dangerous effects of pollution on the ozone layer is that it creates holes in the atmosphere, which allow powerful ultraviolet rays from the sun to reach the Earth’s surface. Many varieties of atmospheric pollutants — toxic chemicals, synthetic substances, such as DDT, and manmade chemicals — enter the atmosphere. They may remain intact and linger for decades, even up to a century, which gives them time to create considerable damage to the atmosphere.
