Don’t count on it. Human civilization depends heavily on trust and cooperation, and a large number of complex systems functioning which nobody completely understands and most people barely notice. The whole endeavor is quite fragile.
Once basic systems start breaking down, people start starving and dying, and societies start to collapse, it can get real bad in a hurry.
There have been plenty of past examples of large-scale societies collapsing into ruin, with the survivors fleeing or dying out.
You're both correct, you're just talking past each other.
Given enough time, perhaps we would be able to work around the disappearance of bees, for example. But that assumes the structure of society can survive that long. Climate change can cause agricultural collapse (due to droughts, floods, blights, etc.), which will lead to food shortage leading to revolts and famine. How many bee pollination researchers will be able to work through that crisis? Governments tend not to survive so well through disasters on the scales we are talking about.
> The most essential staple food crops on the planet, like corn, wheat, rice, soybeans and sorghum, need no insect help at all; they are wind pollinated or self pollinating. Other staple food crops, like bananas and plantains, are sterile and propagated from cuttings, requiring no pollination of any form, ever. Further, foods such as root vegetables and salad crops will produce a useful food crop without pollination, though they may not set seed; and hybrids do not even require insect pollination to produce seeds for the next generation, because hybrid production is always human pollinated. Many of the most desirable and common non-hybrid crops, like heirloom tomatoes, are self pollinated, which is what makes their cultivars stable. [1]
There's a second misconception that the number of domestic bees is declining. This also isn't true. I think people are confused because of the increase in Colony Collapse Disorder. The actual number of domestic bees has increased over the past decade.

I wonder, though... we know, for example, that bees pollinate plants, and that we need plants to be pollinated for our survival. But if the bees die out, we can figure out another technical way to pollinate plants - it might be a pain to carry out, and we might be kicking ourselves for not saving the bees before it got to that point, but it can be done. If it comes down to a matter of survival, humans a a species will figure out a way to get what needs to be done, done. You might say that saving the birds and the insects now is the "simpler" route than replacing them, but it's starting to look like you'd be wrong, and we're not going to have any choice but figure out how to keep the human race going without them.
