I looked at a text a friend of mine wrote. She almost always uses "would be" or "would have" instead of "will be" or "will have".
An international team of scientists collected insects with so-called “Malaise traps” in 63 protected areas in Germany. This long-term study revealed that the number of flying insects decreased by more than 75 percent in the time from 1989 until 2016. Other worldwide studies met or exceeded these figures.
For instance, the consequences of the extinction of bees would be a serious matter. One-third of our food wouldn't exist if these insects didn´t pollinate the blossom of plants.
In my opinion, we need a worldwide prohibition of pesticides. Another idea would be to build vertical gardens in densely populated cities. Vertical gardens would have a huge number of positive effects like providing food and a home for insects. The plants would also clean up the air. Vertical gardens would reduce the air pollution.
She intends to say this would be true hypothetically. I think it should be "will" in every case, but after looking up (would vs. will) I am not sure anymore. Which is right or best here?
To me, using "would" goes in line with saying that one believes a certain thing will happen as a result of an event in the future like in:
She'd look better with shorter hair.
Using "will" instead of "would" sounds very drastic to me in comparison in the text. But maybe would is to "weak" since insects do die more rapidly than ever...?!
Will means "it will definitely happen" to me here. Would means "it´s very likely to happen when looking at some of the facts but it´s ok for now" to me.
I am confused if I misinterpret will and would generally speaking as well as in this example...
