Physics and Fighting Climate Change

Previously I thought:

Climate change > global warming > many animals will die > humans will die also > conservation and preservation of environment & ecology > Biology

and

Climate change > global warming > greenhouse gases > CO2 > fossil fuels > chemical substances > chemical technology > Chemistry

but now (after some literature review) I think:

Climate change > global warming > greenhouse gases > CO2 emission> fossil fuels & wastage of energy > Energy > generation & conservation of energy > electricity & power > renewable energy > nuclear energy > Form 4 & 5 Physics chapters > PHYSICS

This is nearer to mitigation of the impacts from human activities on the environment because energy is practically our life. All of us can do something about it. You don’t need to be a super physicist to contribute to fighting climate change.
- Switch of the lights and fan (and other electrical devices) when we don’t need it
- Choose electrical devices that are more efficient (convert higher percentage of energy)
- Choose transportation mode or purchase vehicle(s) that are using greener energy (eg. Solar-powered or electricity-powered vehicles are “greener” than fossil-fueled vehicles, not saying that they are absolutely green, but greener than their counterpart)
- Say “no” to unnecessary packaging (producing extra packaging is some sort of energy wastage, even if it’s recyclable; not to mention their non-bio-degradable friends ie plastic bags and polystyrene)
- First REDUCE, then REUSE, last RECYCLE. Not the other way round. Recycling uses MORE energy than reducing wastage.
- Eat more vege and less meat lah (producing meat consumes more energy than producing crops)

Just like the TESCO philosophy, “Every little helps” :)
