To have a significant impact, we will need technological innovation and strong environmental policies 
.
Why should we make personal changes?
There are three main reasons our personal changes still matter:
- Our actions cause a ripple effect: if we change our lifestyle, others are likely to follow
- People will take you more seriously as an environmentalist if you practice what you preach
- If we only buy sustainable products, companies are incentivised to adopt more environmentally sustainable practices to meet your demand . This is called voting with your wallets
Vote if you can!
As well as voting with our wallets, we can also vote with our … votes! By voting for politicians that support emissions-reducing policies, such as carbon taxation and tighter environmental regulations, we can hope to see governments taking action against the climate crisis .
Conclusion
Personal action still has a role to play in reducing carbon emissions, but is not enough alone .
People in developed countries can and should reduce their overall consumption . But, humanity as a whole will need to shift consumption to sustainable products. This means eating low-emission diets, taking low-emission transport, etc.
Another great way to help solve climate change is to choose high-impact careers that work to find solutions to our current sustainability problems, or raise awareness in others.
