    Fighting "climate change" is like trying to drain the ocean. You're not going to get anywhere. While transitioning away from fossil fuels isn't the worst idea, it's not going to happen overnight or in most of our lifetimes. Might as well get used to using them for the next 50+ years.

    If you really believe this bullshit, then it's your duty to completely cease any carbon generating activities. Quit eating, driving, using electricity, phones batteries, or endorse nuclear power. Only by returning to the 18th century will you begin to help the earth. Or kill yourself. Either way, take the lead.
