1

What four types of pollution are there?

Air pollution,
Noise pollution
Water pollution
Litter

2

What are the causes of water pollution?

Human sewage, animal slurry, oil spills

3

How can we stop noise pollution?

Choose products with lower noise emmissions

4

What are the effects of air pollution?

Respiratory diseases, eye irritation, acid rain, climate change

5

How can we stop littering?

Recycle, dispose waste carefully, avoid unnecessary packaging, don't litter

6

What causes air pollution?

Sulphur dioxide, carbon monoxide, smoke from coal and oil, carbon dioxide from breathing

7

What are the effects of water pollution?

Dead fish, bad smells, illness

8

What causes litter?

Careless disposal of waste?

9

What are the effects of noise pollution?

Depression, anxiety, insomnia, irritation

10

How can we stop air pollution?

Use natural gas and smokeless coal, use energy effecient appliances, use pump action sprays

11

What are the effects of littering?

Damages cities, towns and counteysides, negative effect on tourism

12

How can we prevent water pollution?

Choose phosphate-free detergents, use safe garden chemicals, use the right amount of fertiliser

13

What are the causes of noise pollution?

Factories, transport and loud music

14

What is acid rain?

It is formed when carbon monoxide, carbon dioxide, or sulphur dioxide mixes with the moisture in the atmosphere to make weak carbonic acid, this damages trees, limstone, fish and metals in buildings

15

What causes the greenhouse effect?

These are oils, gases and petrols, deforestation, methane, nitrous oxide, carbon dioxide, cfc's or cfc products

16

What are the two types of waste?

Organic waste and inorganic waste

17

What is organic waste?

Organic waste is waste that can be broken down

18

What is inorganic waste?

Waste that can't be broken down

19

What is biodegradable waste?

Waste that can be broken down and made harmless by bacteria or other natural means, organic waste is biodegradable

20

What is landfill?

Burrying waste but can be hazardous to humans and the enviroment.

21

What is an incinertator?

A method of disposing waste by burning it but is hazardous to humans and the enciroment

22

What does the hierarchy of waste managment refers to?

Reduce, reuse and recycle

23

Name from top to bottom what is in the pyramid for disposong waste?

Prevention, reduce, reuse, recycle, energy recovery and disposal

24

What is prevention?

To avoid needless package

25

How does reductions save the enviroment?

Buy less and use less

26

What is reusing?

Reuse goods for other purposes

27

Where can we recycle?

In bottle banks, clothes banks, battery collection points and composting.

28

What is energy recovery?

Burning of waste or manure for home heating, methane collection.

29

Name a disposal of waste that should be a last resprt

Landfill

30

What can be recycled?

Metals, glass, paper, oil, plastics, clothes, rags, batteries and mobile phone

31

What are the benefits of recycling?

It saves on energy, trees, import bills it also reduces litternand creates jobs

32

What things can be composted?

Grass clippings, egg shells, fruit and vegetable waste, dead leaves, coffee grounds, tea bags, uncooked food scraps(not meat or fish), general garden waste

33

What are the benefits of composting?

It saves landfill space, reduces greenhouse gases emmission from landfill, reduces incinerators, enriches soil, saves money

34

Name some enviromentally shopping guidelines

Walk to the shop, bring reusable shopping bags, buy concentrated products, buy loose goods, buy recycable goods, don't overpack, buy CFC-free products,

35

What are the EU Ecolabels?

They indicate that products and goods sre enviromentally friendly

36

How many products have the ecolabel?

26

37

What is the function of the ozone layer?

It protects the earth from the ultraviolet (UV) rays from the sun.

38

What would the consequences be if there was no ozone layer?

Skin cancers, cataracts, eye disorders, crops won't grow, damage marine life and building materials

39

What destroys the ozone layer?

CFC

40

Where are CFC's found in?

old refrigerators and air conditioners, aerosals, foam packaging and halons(found in fire extinguishers)

41

What does CFC stand for?

ChloroFluoroCarbons

42

When did scientists discover the hole in the ozone layer

In the 1970s

43

How can we save the ozone layer?

Choose ozone-friendly aerosols, use pump action sprays or roll on deodorant, choose products with CFC free containers, try to recycle cfc equipment when replacing fridges or air conditioners

44

What is the greenhouse effect or global warming

When greenhouse gases such as petrol, oil and gases add to the sun absorbed to the earth this can slowly cause the layer to keep the excess heat
