«11 WORST EFFECTS OF POLLUTION»

https://youtu.be/X3Y-09d634A

Definition of Pollution

Addition of any substance to the environment at a rate faster than it

can be dispersed, diluted, decomposed, recycled, or stored in some

harmless form.

The substance can be: solid, liquid, gas or any form of energy (such as

heat, sound, or radioactivity)

Major kinds of pollution:

• air pollution,

• land pollution,

• water pollution.

RATE FASTER: più velocemente

AIR POLLUTION

Caused by many humanactivities such as cooking,driving and industrialactivities;

These activities releasemany chemical substancesevery day into the air, thatrelease causes globalwarming and acid rain;

Air pollution has increasedtemperatures, making ittough for any form of lifeto survive.

INCREASE: aumentare – SURVIVE: sopravvivere

LAND POLLUTION

Land pollution means

degradation or destruction

of earth’s surface and soil,

directly or indirectly as a

result of human activities.

It is caused by many reasons

such as:

deforestation,

agricultural activities,

industrialization

SURFACE: superficie

WATER

POLLUTION

It is caused by wastes dumped

into the rivers and other water

bodies;

Also spraying insecticides,

pesticides like DDT on plants

pollutes the ground water

system and oil spills in the

oceans have caused irreparable

damage to water bodies.

Water pollution not only harms

the aquatic beings but it also

contaminates the entire food

chain by severely affecting

humans dependent on these.

CHAIN: catena

WATER POLLUTION…

Water they say is life, and indeed they were right. With about

70% of the earth’s cover being water, it undeniably becomes

one of our greatest resources.

INDEED: certamente – UNDENIABLY: innegabilmente

Waste water: Wastewater is any water that has been affected by human use.

Types of wastewater include: domestic wastewater from households or industrial wastewater from industrial activities.

Households: may produce wastewater from flush toilets, sinks, dishwashers, washing machines, bath tubs, and showers.

Industrial activities: recent trends have been to minimize such production or to recycle treated wastewater within the production process .

River pollution: some of the most polluted rivers in the World

RIVER COUNTRY

GANGE INDIA

RIO BRAVO MEXICO and USA

ELK USA

DANUBE EUROPE

MEKONG ASIA

MURRAY-DARLING AUSTRALIA

NILE EGYPT

Gange:

Gange is considered to be the fifth most pollutedriver in the World.

The main causes of water pollution in the Gangeriver are:

Human waste: a large proportion of the sewagewater with higher organic load in the Gange is from thispopulation through domestic water usage.

Industrial waste: chemical plants grow along the sideof the river.

Religious traditions: during festival seasons, over 70million people bathe in the Gange to clean themselvesfrom their past sins.

SEWAGE: scarico – BATHE: fare il bagno

Sea pollution:

In the sea there are many kinds of pollution such as rubbish, oil, chemicals and

even sewage. In many ways it is our own actions that lead to pollution and in

some cases we can do something about it.

The Great Pacific

Garbage Patch:

The Great Pacific Garbage patch, also

described as the Pacific trash vortex, is

a gyre of marine debris particles in the

central North Pacific Ocean discovered

between 1985 and 1988.

The patch is characterized by

exceptionally high relative pelagic

concentrations of plastic, chemical

sludge, and other debris that have been

trapped by the currents of the North

Pacific Gyre.

It is a collection of marine debris in the

North Pacific Ocean.

It spans waters from the West Coast of

North America to Japan.

GYRE: vortice – DEBRIS: rifiuti - PELAGIC: oceanico – SLUDGE: poltiglia

Beach pollution:

Beach pollution is a persistent problem.

Nearly 4000 beach closings and advisories

were issued by the state and local

governments in 1995.

Studies have shown that beach pollution is

usually infrequent and confined to local

areas. Problems can develop in areas near

pollution sources after a heavy rainfall or

when a sewage treatment plant

malfunctions.

RAINFALL: precipitazione

Oil spills:

An oil spill is the release of a liquid

petroleum hydrocarbon into the

environment.

Oil spills penetrate into the structure

of the plumage of birds and the fur of

mammals, reducing its ability, and

making them more vulnerable to

temperature fluctuations.

Clean-up and recovery from an oil

spill is difficult and depends upon

many factors, including the type of oil

spilled, the temperature of the water

and the types of shorelines.

SHORELINES: bagnoasciuga

Animals and pollution:

Water animals:

Acid rain kills fish in lakes and streams by increasing the acidity of water.

Water polluted with different chemicals can cause decline of population in many water species.

Water pollution can also lead to huge growth of toxic algae which when eaten by other animals

may cause serious diseases and death to these animals.

Many dolphins and other animals get caught up in the plastic that holds soda cans together.

These animals also get caught up and trapped in plastic bags and other plastic products that are

thrown into the ocean.

Land animals:

Animals can get entangled into trash that is polluting their environment and get stuck.

Animals might eat polluted trash in their environment which may lead to their death because of toxic

substances in the trash.

Animals may breathe in polluted air which could lead to them becoming ill or to their death.

Pollution from not recycling can cause our soil and plants to become toxic, harming the animals that

may eat plants or soils.

Some small things that everyone

can do to reduce water pollution:

DO NOT pour fat from cooking or any other

type of fat, oil, or grease down the sink.

Run the dishwasher or clothes washer only

when you have a full load. This conserves

electricity and water.

Minimize the use of pesticides, herbicides,

fertilizers.

Innovation to reduce water pollution:

Seabin project:

The Seabin is a floating rubbish

bin that is located in the water at

marinas, docks, yacht clubs and

commercial ports,

it moves up and down with the

range of tide collecting all floating

rubbish.

The Seabin also has the potential

to collect a percentage of oils and

pollutants floating on the water

surface.

DOCKS: moli

Plastic-eating bacteria:

Federica Bertocchini saw the worms pierce

a bag of polyethylene in a short time, a

material that in nature was disposed in

more than 400 years.

This discovery will solve the serious

problem of the presence of enormous

quantities of plastic present on the planet

that nature disposes of in more years.

22 April 2018:

The 2018 edition of the World

Earth Day, promoted by ONU

and celebrated on Sunday 22

April, was dedicated to the fight

against plastic pollution.

This problem is badly damaging

the oceans and lands, damaging

marine life and our health.

We chose to talk about the pollution because it’s a serious

problem that must be resolved as soon as possible to preserve the

destruction of the global ecosystem to allow next generations to

live in a healthy and clean planet. We decided to focus on water

pollution because water is the main source of life of humans,

animals and plants!
