Writing Assesment.

                                                                    Acids rain

Acids rain caused from natural sources like volcanoes but mostly it came from the burning of fossil fuel, vehicles, and manufacturing oil refineries and most of acids gases are blown into the sky and they mix with clouds and causes acids rain. Acids rain happens when sulfur dioxide and nitrogenoxide aree emitted into the atmosphere and transported by winds and air currents.


                                                                     Deforestation 
The most dramatic impact is a loss of habitat for millions of species as most of the animals live in the forest. Deforestation also drives climate change. Forest soils are moist, but without protection from sun-blocking tree cover, they quickly dry out.  Removing trees deprives the forest of portions of its canopy, which blocks the sun’s rays during the day, and holds in heat at night.Trees also play a critical role in absorbing the greenhouse gases that fuel global warming. 
                                                                        Global warming
For some years, global warming, the gradual heating of Earth's surface, oceans and atmosphere. Global warming is real and is caused by human activity, primarily the burning of fossil fuels that pump carbon dioxide, methane, and other greenhouse gases into the atmosphere. More than 197 international scientific organizations agree that global warming is real and has been caused by human action.
