What effects will the wall have on the environment?

     President Trump wall should not be built because its construction will have costly environmental effects. This in large part stems from the amount of cement that will be utilized in its construction. According to an article posted in the journal Scientific American, cement production is one of the world’s major sources of greenhouse gasses (Bolstad). With this fact in mind, a project such as Trump's wall will need immense amounts of cement. One source estimates that the project will require as much as 1.9 million tons of cement (Johnston). The amount of greenhouse gases this, in turn, will equate to will be soul crushing to efforts to reduce climate change. Greenhouse gases are a key contributor to such things as ozone depletion and warming climates ("Medically Reviewed"). Furthermore, if this were not bad enough, the wall will result in tons of smog being emitted into surrounding air. For residents in nearby areas, this will lead to health problems such as lung damage and worsening asthma symptoms ("Medically Reviewed"). One cannot be pro- mother earth and simultaneously pro-  border wall. The choice must be made.
