Answer:
I don't think it was because your room wasn't clean. The main cause of bed bugs is travel, which means most likely you got one on you when you went outside or something, and you accidentally got it into your room. Bed bugs hitchhike on luggage, clothing, people, etc.
If there are blood stains or dark/rusty spots on your bed/pillow, there are definitely bed bugs. The bloodstains/spots come from you crushing the bed bugs accidentally. The place where bed bugs are (in this case, your room), may also begin to smell bad. You might also see eggs laid by the bed bugs.
Let me know if you have any other questions. Good luck!

The reason why the Greenhouse effect and the ozone layer are considered as related environmental issues is that they both are affected by the human activity, and they both cause rise of the global temperatures.
Explanation:
The greenhouse effect represents an atmospheric effect on the planet that results in global rise of the temperature. The cause of this effect is the accumulation of greenhouse gasses in the atmosphere, which have the property to trap big portion of the heat.
The ozone layer depletion is a process through which the ozone layer is destroyed. With the destruction of the ozone layer, ozone holes occur, which in turn results in higher UV radiation. The stronger the UV radiation, the more damage is cause on the living organisms.
Common things of both these processes are:
- the human activity has big influence on them
- the global temperature rises
- they cause drastic environmental changes and damage
