engineer do to improve environment 
Outline
Title : what had engineers done to improve our environment
Introduction :
Engineers job –> a person who designs, invent, builds, and improve our technology
Had done many improvement to our lifestyle.
a. What car you drive now? Old days :
b. What camera we used today/nowadays? Old days: ? big and bulky camera
c. What phone we use now?
However , there is always have a side effect under the technology
Main point 1:
Recommend to use of solar power
1. It is a renewable energy
2. Solar energy does not cause pollution
3. It is estimated that the world oil reserves will last for 30 to 40 years. On the other hand, solar energy is infinite
4. Example: Changi Airport and KLIA designed to fully used the solar energy
Main point 2 :
Reduce the uses of chlorofluorocarbons (CFC) and reduce the energy consumption.
1. Past: most cooling device like refrigerator and air conditioner using CFC
2. Effect : destroy the Ozone layer in the atmosphere
3. Now: upgrade of the air conditioner and refrigerator without using CFC and less energy consumption.
4.
Main point 3 :
The uses of biodegradable item
1. more technologically advanced
2. produce materials - withstand extreme temperatures, durable and easy to use
3. Biodegradable products are those that can be decomposed by microbes and other natural biological processes
4. 80% vegetable starch and 20% of vegetable oil
5. Biodegradable items are useful in reducing the amount of waste in landfills
Plastic bags
10–20 years
Soft plastic (bottle)
100 years
Hard plastic (bottle cap)
400 years
