Under the sea?

Seriously?! You need to look for the biggest cause of climate change not just hang it on fossil fuel

In nicely heated and cooled houses?

Sadly, they're working on space programs & that's why they have & keep Brainwashing the young ones at school "ROTC, Patriotism to join the army etc... not to mention the stupid video games = Brainless killing Machines. We need to Keep Supporting & looking Clean Energy & Activism

What do we do about China, India, Africa and Russia??

Folks alot smarter & researched than I said our window to fix this was 40 yrs ago... Anything we do know is for profits & to feel good. Human existence on earth is toast, so spend your time loving hard & enjoying life like you have a terminal condition... Because we do. Blessings

Plus the business of swindling should end. Things like Mineral Oil being renamed "Fossil Fuel" to drive up prices and create image of scarcity, like dumping diamonds. & Though the 2nd most abundant liquid on earth, it belongs in the ground, moving has catastrophic results.

Don't have offspring, but within 30 - 50 years I expect 1 to 2 billion climate refugees to unstoppably migrate out of regions that exceed human habitability limits due to climate change to habitable regions & I expect wars around tbe world over the climate refugee mass migration.

The grandchildren of the super rich have vast and for some reason mostly vagina-shaped bunkers to lord over for a sad, brutal few generations.

Fossil fuel has given you almost everything you use for daily life. Don't give up on it now!
