What are the causes of water pollution?
Human sewage, animal slurry, oil spills
How can we stop noise pollution?
Choose products with lower noise emmissions
What are the effects of air pollution?
Respiratory diseases, eye irritation, acid rain, climate change
How can we stop littering?
Recycle, dispose waste carefully, avoid unnecessary packaging, don't litter
What causes air pollution?
Sulphur dioxide, carbon monoxide, smoke from coal and oil, carbon dioxide from breathing
What are the effects of water pollution?
Dead fish, bad smells, illness
What causes litter?
Careless disposal of waste?
What are the effects of noise pollution?
Depression, anxiety, insomnia, irritation
How can we stop air pollution?
Use natural gas and smokeless coal, use energy effecient appliances, use pump action sprays
What are the effects of littering?
Damages cities, towns and counteysides, negative effect on tourism
How can we prevent water pollution?
Choose phosphate-free detergents, use safe garden chemicals, use the right amount of fertiliser
What are the causes of noise pollution?
Factories, transport and loud music
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
What causes the greenhouse effect?
These are oils, gases and petrols, deforestation, methane, nitrous oxide, carbon dioxide, cfc's or cfc products
What are the two types of waste?
Organic waste and inorganic waste
What is organic waste?
Organic waste is waste that can be broken down
What is inorganic waste?
Waste that can't be broken down
What is biodegradable waste?
Waste that can be broken down and made harmless by bacteria or other natural means, organic waste is biodegradable
What is landfill?
Burrying waste but can be hazardous to humans and the enviroment.
What is an incinertator?
A method of disposing waste by burning it but is hazardous to humans and the enciroment
What does the hierarchy of waste managment refers to?
Reduce, reuse and recycle
Name from top to bottom what is in the pyramid for disposong waste?

What is prevention?
To avoid needless package
How does reductions save the enviroment?
Buy less and use less
What is reusing?
Reuse goods for other purposes
Where can we recycle?
In bottle banks, clothes banks, battery collection points and composting.
What is energy recovery?
Burning of waste or manure for home heating, methane collection.
Name a disposal of waste that should be a last resprt
What can be recycled?
Metals, glass, paper, oil, plastics, clothes, rags, batteries and mobile phone
What are the benefits of recycling?

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
What are the benefits of composting?
It saves landfill space, reduces greenhouse gases emmission from landfill, reduces incinerators, enriches soil, saves money
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,
What are the EU Ecolabels?
They indicate that products and goods sre enviromentally friendly
How many products have the ecolabel?
What is the function of the ozone layer?
It protects the earth from the ultraviolet (UV) rays from the sun.
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
What destroys the ozone layer?
Where are CFC's found in?
old refrigerators and air conditioners, aerosals, foam packaging and halons(found in fire extinguishers)
What does CFC stand for?
When did scientists discover the hole in the ozone layer
In the 1970s
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
