I really don't think that trying to preserve as many species as possible is a rational goal. It causes economical harm for example. What's wrong with extinctions?
I often hear about the costs of climate change. What I don't hear about is:
1. possible benefits; what we should assess is benefits - costs, not costs alone,
2. possible benefits and costs of so called solutions. For example introducing electric cars will increase demand for batteries and electricity. That means increased demand for coal, gas or nuclear power. What will be the effects of these?
I'm just very skeptical about models of so complex systems. My skepticism is increased by the involvement of politics and the hype around the topic.
The climate will change. That's completely natural and I can't see a reason to stop it (honestly I think it's impossible). Humans and other animals will just adapt and the evolution will continue.
Some movements are:
- h, j, k, l,
- f <char> - the given character,
- w / b - beginning of the next / previous word,
- 0 / $ - beginning / end of the line.
Some actions:
- d - delete
- dd - delete whole line
- y - yank (copy to the Vim's clipboard)
- p - paste
- c - change
- <n> G - go to the n-th line.
Their combinations could be:
- d f . - delete from the cursor to the first period
- d w - delete the current word
- c w - change the current word
- d 0 - delete to the beginning of the current line
- dd 10 G p - delete the current line (that also puts it in the Vim's clipboard), move to the 10th line and paste the deleted one there.
Of course it gives you much more: searching, replacing, scripting, plug-ins, syntax highlight, auto-completion, browsing etc.
