An email from Nicolas Guzmán Pardo from Colombia
Could you talk about vocabulary related to pollution and contamination?Also I decided I was going to listen to all of the episodes available, from January 2010, and I’m now in February 2012. Only one of you recorded the episodes back then, right?
Nicolas recently took the IELTS test in Bogotá. He got 7.5 overall with 8,5 in listening and reading – without having a lot of time to study and prepare for it!
Nicolas also did the homework we gave him! He says There’s a tendency to use the term ‘fourth’ over the word quarter in USA when referring to 1/4,
It is believed to be this way because there is a coin that is called “quarter” that is worth 1/4 of a dollar, so mainly in maths people use fourth so it doesn’t get confused with the coin.
Pollution and contamination
We spoke about vocabulary related to the environment in http://www.inglespodcast.com/96
Contamination is the presence of a substance where it should not be. It doesn’t necessarily do harm.
Pollution is the presence of any substance or material that may cause a harmful effect on humans, animals and plants. If there is no harm, then it is called contaminant.
All pollutants are contaminants, but not all contaminants are pollutants. (source: https://www.quora.com/)
The word “pollution” is commonly used to talk about the environment, including exhaust fumes from vehicles, smoke from factories, rubbish in the sea, etc.
Whereas the word “contamination” is commonly used to talk about undesired elements getting into food or drinks, or unwanted substances, such as bacteria, in a “clean room” or sterilised space, etc.
Biodegradable – capable of being decomposed by bacteria or other living organisms
Global Warming – an intensification of the greenhouse effect due to heat trapping gases in the atmosphere. Leading to climate change.
Light pollution – brightening of the night sky caused by street lights and other man-made sources, which has a disruptive effect on natural cycles and inhibits the observation of stars and planets
Noise pollution – harmful or annoying levels of noise, such as an airplane
Sludge – the solid remains after the treatment of sewage
Smog = smoke + fog, or haze, or a combination of other pollutants
Clean energy – solar power, wind power, tidal power, wave power, geothermal energy, biomass, and according to some people nuclear energy
litter, rubbish, trash, garbage, waste
Discussion
Should the developed nations be held accountable for protecting the earth? If so, how would this affect the progress of developing countries?
If you could choose one alternative energy source to develop which one would you choose? Why?
