Listen, and please listen. I'm 48. I grew up from birth listening to David Suzuki and Bob MacDonald on CBC. Since a small child I have known we are killing the planet. Oceans are acidifying and warming up. Coral reefs are dying. Species are in mass extinction. This has been 40 years my generation has personally experienced.
We are jaded as fuck. We are the smaller crunch generation. We had and have limited political power. We are stuck as the first generation to have to raise and support kids who can't leave home and parents who are living longer and poor. I will repeat we are jaded as fuck.
But you know what? Life goes on because only a pussy gives up and the wheels are going to grind you down regardless so you may as well fight.
You will, in many ways rightly, highlight "well this is different!" and in many ways it is. Which is why I will repeat, are you a bitch who gives up or will you fight? Fight locally by supporting local businesses. Fight locally by working on influencing your friends and family to change their views. Vote for those who will change things for the better while being pragmatic that positive change takes time. Acknowledge what you can change and what you can't and accept that.
I know it's hard and it's hackneyed but at lot of the youth and people in general need to get off their phones and talk to the people in their community. This online world is toxic and does not reflect reality. The world is going to survive with or without you.
