(T)he Mayans invented the Internet and television? My, they were way smart. Then again, Philo was 1/64th Mayan. I knew they invented the eectric popcorn popper and the citronella candle to keep the huge bugs at bay.
You forgot open heart surgery. Those Mayans certainly had that down to a fine art...
We certainly have a fine can of worms opened here. I tend to both agree and disagree (my #1 survival tactic in this house) with almost everything written in this thread so far, but it isn't really worth arguing over. A few of my usual lopsided comments will follow as it's all I feel up to posting today.
In a sense, there is still natural world left. But 'natural' in the sense that everything is constantly changing, and what was there a century or a decade or a year or even a month ago, isn't the same now as it was. One of my favorite sayings is "time passes, things change". As a personal example of this, twenty years ago I was 50 and a bit and still as active (so I thought) as I had been in my twenties and thirties. Now I'm 70 and a bit and still (surprisingly) active for my age, but age has wearied me and when I look in the mirror, I realise I can no longer fool myself. Time has passed and from what I see, one heck of a lot has changed. This is 'natural'.
Here in western Victoria (Australia) where I live, we still have some of the (very little) natural bush land left in the state, but whenever I venture out with one of my cameras in my backpack or a pocket I find human detritus everywhere, some of it going back a long time. More abandoned 1950s and 1960s Aussie cars can be found in that bush than in all the collections in this country, but in the condition these are now all of these rusted old motor (or mostly motorless) vehicles are not worth restoring anyway. My partner likes old bottles, so whenever I find some in a long-abandoned dump, I tend to pick them up and take them home, thereby helping in a small way to clean up and improve the natural landscape. I do what I can, even to the point of being uber-careful where I step to avoid crushing the local flora. The fauna I see consists mostly of kangaroos and wallabies and these tend to stay well away from me, so neither of us are in any great danger from each other.
We can only do what we can do in our own limited ways. At home we are slowly putting in a natural bush garden to try and keep some plants going as climate change accelerates and global warming takes over. It's slow but steady work. A few trees will go in next month and much of the suburban lawn and pretty-flower plantings in the back yard are being pulled up and a more natural environment developed as we go. Already many local birds are finding their way into our existing trees, to the annoyance of the elderly right-wing nutter next door (a retired farmer who basically considers all Australian birds to be destructive pests worth only blasting away with a shotgun. Like everyone he is entitled to his opinions no matter how blinkered or stupid they are, but for us the biggest annoyance with this worthy is his two big dogs which live in the back yard and bark loudly day and night but are largely ignored except for being fed when he remembers to do it.
Humankind is basically stupid and already we are paying a high price for this. In recent times we are starting to realise the natural disasters we and our future generations (however many will survive in the coming big mess) are moving towards now, are basically something we are responsible for and it is high time we begin doing some intelligent things before it's too late. Time will tell and we'll see - there isn't really much left of the former unless we wise up quickly-smartly and start doing some right things while we can.
Enough rant for today. We are out of lockdown today in Victoria state and I'm planning a bush walk on Thursday with my Nikon D800 and a Voigtlander Perkeo II loaded with FP4 in my coat pocket. After four days of lockdown I'm ready for some fresh air and maybe one or two 'roo sitings.
As an aside - for what it's worth we have a house cat named Schroedinger, an indoor mog of impressive dimensions who lives for his two feeds a day and long naps on our bed and is mostly unimpressed by all these goings-on. For him climate change is what I do with the heating thermostat in the living room.
