isn't true, it's still a great metaphor. Dangers that come on us gradually often go unnoticed until it's too late. The North Korean nuclear program, for example. Who took that seriously until they did a successful test?
Pollution is another gradual danger. Sure, we all know it's bad, but nobody is dropping dead so we don't think about it. . .except we're now accustomed to buying bottled water because it's marketed as safer than tap water, and people wearing masks in big cities isn't remarked on anymore.
According to the fascinating book, The World Without Us, the most harmful thing we may be doing to our planet may be pumping vast amounts of plastic into the ocean. Tiny indigestible bits of plastic are finding their way into the systems of all sea life, and we simply don't know how that might affect them.
Out of sight, out of mind.
Why wait for the end of the world? We're bringing it closer every day.
