To determine whether technology is the main factor of that drives in the advancement of knowledge in the changing landscape of environmental sciences.

Economy

How does economy affect the advancement?

If economy is unstable, there will be less funds to do Research & Development(R&D)

Less inventions

Less advancement in advancement of knowledge

Education

Imparting knowledge to students

Experimenting

New invention

Natural disaster

Earthquake in Japan

How does it lead to advancement of knowledge in environmental science?

Before advancement of technology, building will collapse after earthquake.

Waste and rubbish that produced by earthquake will harm the environment

For example earthquake cause leak of nuclear substance in Japan

After advancement of technology, building would not collapse easily after earthquake (earthquake resistant building)

Waste and rubbish will be reduced

Need technology, knowledge, money and support from government.

Technology

R&D

Inventing machines

With more machine, we can apply our scientific knowledge to improve the landscape of environmental science

Weather prediction machine: thermometer, air quality models etc

Without the help of technology, the time taken will be longer, the man power will be demand.

Lack of raw material

For example : fossil fuel

Singapore do not have fossil fuel, so we use solar energy do replace fossil fuel.

Solar energy is renewable while fossil fuel is non-renewable energy.

The availability of solar energy is abundance

solar water heater

solar panel to provide electricity
