With our present rate of pollution and environmental destruction, I estimate that the human race is on track for extinction in the next 200 years, not 1000.
The majority of people either don't care, or make whiney excuses about how they have to run an oil furnace instead of just insulating their damned house.
As pollution and the climate disaster destroy all our food producing lands, and all fish stocks in the oceans, it seems likely that the wars fought over the last remaining food supplies will escalate until nuclear, biological and chemical weapons are deployed. Extinction is then the most likely outcome. This could happen as early as 2100.
It's possible, that instead of extinction, humanity may just be reduced to a few nomadic bands of brutish, ignorant savages. Perhaps those people might rebuild another civilisation in 20,000 years or so. Perhaps they will not. When I look at human history, it seems like a tremendous fluke that we ever put together a civilisation at all.
I have worked for most of my life to try to find ways to prevent these outcomes. I have reduced my personal carbon footprint by 80% compared to other people in my country. I generate twice as much solar power as I use, and put the surplus into the grid for others. I vote always for parties that have policies to address these problems. It has all been in vain, as greed and ignorance triumph always. Our farmers vote for more droughts, more floods, more frequent and worse wildfires. Our trade unionists vote for more pollution, and our businessmen vote for the right to steal, pollute and murder for profit.
So, my response to the human race is a big, fat, FUCK YOU. I have no children. I have at most 25 more years to live. It's YOUR grandchildren that you are murdering, not mine, so FUCK YOU! I GIVE UP!
