Question
The IUPUI library is faced with thousands of tons of Indiana limestone. Take into account the tons of crushed limestone and cement, and you can easily see that on campus we are surrounded by millions of tons of rock that were mined and built into the structures we see.
Define sustainability and give the three assumptions.
When looking around campus and thinking about the things that you own, do you think that these mineral and rock resources are renewable or nonrenewable? Give examples.
Do you think that they are being replenished as quickly as we are using them? Give examples.
Do you think that future generations will need these same resources? Give examples.
Explanation / Answer
Define sustainability and give the three assumptions.
The limestone mined used to make cement by crushing it powder and adding gypsum for binding. After stone structures, Cement is the best material to make buildings can sustain for 100 or so years. Stone structures have more life than cement but stone structures are expensive and need much more time than cement structures.
Now a days in big cities all over world tall buildings are being constructed with cement. World’s tallest building Burj Khalifa in dubai is of 830 m height and having 163 floors. Such building construction is not possible with stone and rocks. Tall building needs light material to over come weight problem. Now a days high strength and light steel and cements are used for buildings. They are more sustainable than any other material and the life of such buildings can be extended decades be renovating.
The Masjid build in Morocco is of 400 years old. It has salt effect to sea water as it on sea coast. But chemicals used in renovation protecting the building without any damage.
When looking around campus and thinking about the things that you own, do you think that these mineral and rock resources are renewable or nonrenewable? Give examples.
Limestone used for making cement and for constructing buildings is a non renewable resource. These resources are deposited millions of years ago back and taken present form. Getting such deposits again from nature are not possible.
Thatched and bamboo houses resources are renewable. AS grass and bomboo vegetation grow every year naturally. So we can make such houses with renewable resources every year. But life of these houses are few years only. They weather fast within 5 or 6 years we have to make new house.
Do you think that they are being replenished as quickly as we are using them? Give examples.
We can’t replenish limestone and other mineral deposits. Because they are non renewable resources. Once we mined it means there is no replacement for it. We have to look for new deposit in new location.
Examples:
1. Granite deposit used for building
2. Marble deposits used for flooring
3. Limestone tiles used for flooring
Do you think that future generations will need these same resources? Give examples.
Future generations may need same type resources for construction of their houses and buildings during their period. But they have to look for new resources available during their time. What ever we are using now may exhaust after few years. So they have to check for new deposits in other areas.
Example:
It is just a thinking, that future generation may not live in houses due to global warming, heat and solar radiation. To escape from these environmental pollutions we created, future generation may have to live in houses constructed in underground levels.
