Topic 1 - Polymers, Farming, Timber, Mining, Deforistation, Sustainability, Drilling Flashcards
What are some environmental impacts of drilling
Dangerous chemicals used to extract the material can pollute the surrounding environment and kill wildlife
When the oils and gas are being drilled carbon dioxide is produced
Oil is harmful to animals
What are some social impacts of drilling
People who live in surrounding areas are at risk from leaking pipes that transport dangerous chemicals
Oil supplies have huge economic impacts on surrounding areas, fishing has to be stopped and tourism can be affected
What are some environmental impacts of farming
Over 50% of usable land has been transformed into farming land
Rainforests are destroyed for plan oil plantations
The removal of large roofer trees causes large scale erosion
What are some social impacts or farming
Farming uses around 70% of the worlds useable water
The soil that is blown away can be blown into important water sources and rivers, destroying important water sources
How are polymers made
Polymers are made mainly using oil which has to be extracted out the ground using drills.
Why are polymers important
They’re important as they allow for the mass manufacture of complex shapes and design that would be difficult or expensive if other materials had been used
6 R’s of sustainability. What is reduce?
Minimising materials used in products. This helps to protect resources that may be rare or expensive
6 R’s of sustainability. What is rethink?
Finding another more environmentally friendly way to make a product
6 R’s of sustainability. What is refuse?
Not accepting items that are damaging to the environment
6 R’s of sustainability. What is recycle
Using preowned and used products to make new items
6 R’s of sustainability. What is reuse
The possibility of a product having another use which will extend its life
6 R’s of sustainability. What is repair
Fixing the product to keep it in use for longer
What is timber
A type of wood that has been processed into beans and planks, a stage in the process of wood production
Where does timber come from
It’s found in trees
What is timber conversion
Turning a log into a pile of boards/planks
Why is timber reused and recycled
Timber is often reused in order to reduce the amount of trees that are cut down. Wash wood and timber is usually divide into pieces which are then loaded into a wood shredder which breaks up the pieces
What is mining
The removal of minerals and metals from the earths surface for example iron ore, gold, silver and diamonds
What are some social effects of mining
It can create a huge amount of employment and income for countries and groups of people
Fish are contaminated from the polluted water supplies
People who have eaten the chemicals can become ill
The contaminated water results in proper not being able to drink, wash
What are some environmental impacts of mining
Chemicals end up in rivers contaminating water supplies
Trees and vegetation are cleared and burned
Trees are cut down in the local areas
What is deforestation
The removal of t es over a large expanse of land
What are some social impacts of deforestation
Indigenous people have fewer places to hunt, resulting in less food to eat
The people who are doing the cutting gain a profit for it
What are some environment impacts of deforestation
Fewer trees and vegetation causes wild animals to have fewer places to live
