1/5

Bio-gas is a sustainable form of producing

energy because

It beneficial to the local people, (it is

cheap, small scale and uses availableresources).

It is also not harmful to the environment,

(it does not cause visual pollution, thecarbon monoxide produced is very littleand the fertiliser produced as a by-product can be used to grow more crops

. How sustainable is the current pattern of resource supply and consumption

,althus Boserup

esourceswill run out esourceswill not run out.

8opulation is growing too fast so people will

use up resources and have none left.

"e will never run out of resources as we will

eep inventing new technology to help us find

new ones.

"e will run out of resources soon, as our

large population has used up too much. Coal

will run out in

"hat are the challenges for the future

6. 9ow can we reduce the demand for resources>

educe3 the amount of electricity you use by switching electrical good and lights off. 1se

energy saving light bulbs to reduce the energy consumed.

euse3 resources lie plastic bags or bottles. 0hese goods are made from products

containing oil (finite resource). eusing them means less have to be produced so oil is

conserved. #lso less bottles and bags will also end up in landfill sites.

ecycle3 0his means that raw materials can be conserved because goods can be made

into other products rather then being wasted.

Invent3 ew technologies can help conserve energy. *ore efficient machinery will use less

energy therefore helping to conserve it. $.g. 9ydrogen fuel cell technology in cars is

looing to use hydrogen instead of petrol, this is also good because the emissions will not

damage the environment, it will only give off water?

$co-%ootprints3 0he area of land and sea that supplies all of the things you need to

survive. It is the impact your lifestyle has on the planet. $.g. by the way you travel places,

the electricity you consume, the food you buy (food miles if you food has been importedfrom around the world it has a large impact because of the pollution caused by

transporting it.) 8eople need to reduce their eco footprints.

!. "hat is the potential to switch to alternative @ renewable resources>

:ustainable development3 *eets the needs of the present without compromising the ability

of future generations to meet their own needs.

0o do this individuals (by reducing, recycling), governments (by introducing laws and

emissions taxes), charities (by pressuring the government and educating people), the

media (by informing people of why and how to help) , 0rans ational Companies (0C4s)

(by trying to use more sustainable approaches and carbon offsetting planting trees) andinternational organisations (by maing agreements on carbon emission targets e.g.

Ayoto agreement) must wor together.
