What would happen if bees disappeared?

Bees have lived for 80 millions of years and their population is decreasing alarmingly even up to 50% of the  bees are disappearing. I have heard lately that Einstein said something like: "Should bees disappear, the human race wouldn't outlive them more than four years". There would be no pollination, some vegetal species would not survive, therefore, some animal species would vanish as well and all our food chain would be altered.
 We have been working on conditionals and this post is written in the second conditional because it is an unreal or improbable situation. Let's see a quick review:

Types:	Form:	Use:	Example:
Zero type	If present simple, present simple.	Habitual results.	If you heat water up to 100º, it boils.
Type I	If present tense, will+infinitive.	Probable results.	If it's sunny, we'll go to the beach.
Type II	If past tense, would+infinitive.	Improbable, unreal situations. Also advice.	If I won the lottery, I would travel around the world.
Type III	If past perfect, would have+ past participle.	Impossible situations because they refer to the past.	If I had listened to my mother, I wouldn't have been so miserable all my life.

 You can practice a little bit at English Grammar 4U online or at Perfect English Grammar.

Just in case you get too negative, you can listen to this song by Beyoncé which is one of my favourite songs, especially because of the lyrics. (it is written using the second conditional because she talks about how she would behave if she were a boy)
