algae+speech

intro
I picked algae as my topic because I like things that are geeen, and because i think that it is a serious environmental issue.

Algae is bad for the environment because the more algae there is in a pond the more fish will die. XD If more fish die, soon the fish will be endangered and eventually they will be extinct, then no more fish.

There are three types of algae, that i consider a problem.this algae is going to find its way into your aquarium tank or pool tank their spores will reach your tank from the air or the water your livestock or foods come in. you cannot stop them from getting in to your tank.

Hair algae
This grows in mats, and looks like fine hair (thus the name), it can grow over rocks, other substrate, glass, pumps, pipes - basically anything in the tank.

Slime algae
This is a greasy alga in red, green or black varieties. It covers rocks and substrate.

Diatomic algae
Is very fast growing brown film that grows on the glass especially in aquariums with strong lighting. There is never a single causal component to algae affecting an aquarium. Rather, it is a combination of factors. These include water quality (phosphates, nitrates & ammonias), accumulation of detritus, lighting, and supplements.

conclusion
I think we should stay away from algae and try not to inhale it. I listed different types of algae so that you know what to stay away from. these are all types of algae that can hurt or kill animals and humans. i know i wouldn't want all of our fish to die, and i know you would want fish to live.
