Từ vựng trích từ Essays chủ đề Environment
- Contamination = pollution by poisons or dangerous elements
The atmosphere in large cities is often contaminated by smog, as we can see in China.
- The biosphere = the relationship between all living things on the planet
Children should be educated on the biosphere through field trips and practical experiments.
- Emissions = gases entering the atmosphere
Scientists spend their whole careers studying the effect of emissions on the climate.
- Pollutant particles = microscopic elements of pollution
I remember going to a factory and seeing the snow covered with pollutant particles.
- Run-off = water that runs from the ground into rivers and lakes
We should try to collect and use more run-off water, to avoid having to recycle water so much.
- The water cycle = the natural process of water moving from clouds to rain and seas
Scientists believe the water cycle is responsible for various natural events, especially in
- Aquifers = underground, natural water stores
My family has a well which connects to an aquifer, giving very pure water.
- Filtration = the process of filtering and removing impurities
Water filtration might be a solution to water shortages in very hot countries.
- Water table = the layer of water below ground
In my town, the water table is very high, and water will appear in even a small hole.
- Tainted = polluted or contaminated

an endangered species.
- Habitat loss = destruction or disappearance of an animal’s natural home

- Food chain = the natural system of animals eating other animals and plants
The food chain has been disrupted by the loss of certain species, with widespread impacts on all animals.
- Dwindling numbers = (to dwindle = to steadily decline in quantity)
States seem to have dwindling funds to pay for animal sanctuaries, although they are still able
to pay for government officials and their perks.
- Extinction = the final death of all animals in a species
Dinosaur extinction may have been caused by a meteor or volcano, but scientists seem unsure
- Famine = a situation where there is a lack of food in an area for a long time
Many singers help make charity songs to raise funds for famine relief.
- Drought = similar to famine, but a lack of water
Drought in central Africa can continue for many years, apparently.
- Irrigation = supplying water to land for agriculture
If we want quick solutions to famine, better irrigation and farming methods would probably be
the first step.
- Catastrophe = a great disaster affecting many people
The continuing destruction of the rain forests is a catastrophe for the global biosphere.
- Exacerbated (= to exacerbate = to make an existing problem worse, accidentally or deliberately)
