No doubt human has making earth worse by the day but i always wonder about save earth slogan. why earth need saving? sure for my kids and grand kids.! but if it look millions of earth to reach where we are now but surely it will take more than 100yrs to make worse for millions with 9billion(then projected world population)
I find this interesting comment from BBC’s program- Earth: The Power of the Planet
in the long run, earth can cope with anything we can throw at it we could clear all the jungles, but a jungle can regrow over a few thousand years. we could burn all earths’ fossil fuels, flooding the atmosphere with carbon dioxide but even then, it will take the planet only a million years or so for the atmosphere to recover even the animals we are wiping out will eventually be replaced by others equally rich in diversity as a relentless work of evolution continues it’s only a question of time the earth will be just fine.Ofcourse its no excuse to do our bit to make this world better place but lets have no isolation- its NOT earth we are trying to save but its just yet another selfish human act.
it’s not to say rapid changes we force on earth don’t matter that is because humans operate on a different time scale we have evolved to life in a world as it is now so in changing this world, we are altering the environment that has allowed the human race to thrive we could be creating conditions that threaten that long term survival of our civilization.
so all this stuff about saving planet earth, well that is not the problem: planet earth doesn’t need saving, earth is a great survivor it’s not the planet we should be worrying about, it’s us.
