ACID RAIN!

Acid rain is rain or another form of precipitation that is acidic. It is caused by emissions of sulfur dioxide and nitrogen oxides which react with water and produce acids. They are emited by the stores, power plant and vehicles which burn carbon and oil.

EFFECTS: The acid rain causes acidity in soils. It changes the soil's composition.
Also, it produces a direct damage in plants that can kill them. 
The aquatic ecosystem is one of the most affected systems because when the acid enters the water (mostly fresh water) the water's PH increases and some species can't survive. Sometimes, this causes the lakes to dry up.


HOW WE CAN FIGHT IT?: We should use more alternative, clean energies.
The goverment should invest more money to investigate  about alternative energies and develop projects to reduce pollution. 
Also, we should use public transportation. 
And most importantly, WE MUST SAVE ENERGY!
