Social-scientific issues

Use of non-renewable energy
Use of fossil fuels that emit greenhouse gases

Examples of several socio-scientific issues that are related to the environment:

Deforestation
Global warming
Air polution
Indiscriminate waste disposal
Water pollution

Socio-scientific issues

Socio-scientific issues of burning of fossil fuels produce greenhouse gases that cause global warming and extreme climate changes.

Source of energy

Source of Energy

Non-renewable energy	Renewable energy
Examples: fossil fuels (petroleum, natural gas, coal), nuclear energy	Examples: Hydro, solar, wind, geothermal, wave
Disadvantages: supply become scarce and environmental pollution (carbon monoxide & carbon dioxide)	Advantages: clean energy, green energy, and pollution free

Application of green technology

Wind energy source replace fossil fuel in the future.
Hydro energy source become one of the main energy sources in the world to generate electricity.
Solar energy source has potential to be developed in Malaysia.
Geothermal energy source replace fossil fuel.
