I wouldn't say this is so obvious. There is also an study that the microwaves (from mobile phones) are affecting the bees and the birds.

Unless cellphones and microwaves were suddenly introduced in 2005 then that is rubbish.
AFAIK cellphones predominantly used 700-900MHz band in the past, and moved to ~2GHz band recently for HSPA/4G LTE

Also there has been a lot of usage of 2.4GHz devices in recent years.

bluetooth? - low power, doesn't travel far

wifi - been around long before 2005

cell phones - don't use 2.4 unless BT or wi-fi, have also been in the 1800/1900 gsm bands long before LTE/data networks

microwave ovens - been around forever.

Doesn't seem to add up.

not saying RF doesn't hurt, just playing devils advocate.
