Ab carbon footprint can be measured for an individual or an organization and is typically given in tons of
CO2.
There are two gases
which people often confuse - CO2 =
carbon dioxide and CO =
carbonmonoxide. Their
names are similar, and they are both dangerous in high concentration. So our best explanation is:
CO2 is produced by gasoline engines that use a catalytic converter.
CO is generated by gasoline engines that do NOT use a catalytic converter. I hope this clarifies the difference for you.
In most cases you will need to say or write something like ‘
to reduce carbon dioxide emissions we have to do something…'
Our next phrase is
hazardous waste.It’s
essential that hazardous waste is handled, stored,
transported, and disposed of properly. No one should touch hazardous waste.
Another popular word when
we talk about environment is contamination. Many people use it as a synonym of pollution, which is not completely correct.
Contamination is the presence of unwanted or foreign substances.
Contamination maybe natural whilst pollution is produced by the influence or activities of people.
