I’m sure that water pollution is not a new case for you.

However, do you really know what water pollution is? Water

pollution concerns the runoff or diffusion of chemicals or wastes

into oceans, rivers, and other watercourses. Pollution of water

is very dangerous because aquatic ecosystems require certain

conditions and will be affected by small changes in chemical

concentrations.

As water pollution is dangerous, it gives bad impacts, including,

on humans. Declining aquatic ecosystems will negatively affect

the livelihoods of people working in coastal areas, while toxins

released from the breakdown of algal blooms will dirty drinking

water. It affects ecosystems as well. Leaching nutrients from over-

fertilised soils and urban waste can cause eutrophication of nearby

waters, which leads to anoxia. Poisonous toxins from algal blooms

will harm fi sh assemblages, and invasive species will be better

adapted to high-nutrient environments and drive out the original

species, which may lead to a loss in ecosystem functio nality. At

the same time, water pollution has effects on environment. Acid

rain will devastate landscapes, while atmospheric deposition of

carbon dioxide will cause ocean acidifi cation.

Which of the following is not a negative impact of water pollution?

• A low aquatic ecosystem level reduces the spirit of the population in coastal areas.

• The availability of drinking water is decreasing.

• Marine ecosystems will be disrupted.

• This is a common problem for people in coastal areas.

• Water pollution is destructive.

“ ... which may lead to a loss in eco system functionality”

What does the bold word refer to??

• Original species.

• Toxic

• Nutrient-rich environment.

• Algal blooms.

• Over-fertilized soil.

It’s obvious that air pollution is risky and therefore gives some effects. It absolutely affects human health. Nitrogen and sulphur oxides cause acid rain and erode limestone buildings. Small particulates can cause respiratory problems, genetic mutations, and cardiovascular diseases. Does air pollution affect the environ ment? The answer is yes. Carbon dioxide will contribute to the greenhouse effect and cause global warming, while acid rain from nitrogen and sulphur oxides will pollute waterways. Aerosols which have a strong absorbing effect will also contribute to warming. We all know that acid rain damages ecosystems. The consequences of global warming like melting ice sheets, forest fires, and migration to cooler regions reduce habitats and shift ecosystem dynamics. These all happen because of air pollution.
