This article discusses the debate and empirical bases of the environmental argument against Latinx immigration to the United State (US) since the 1980s decade. The environmental argument against immigration states that the level of immigration (undocumented and legal) has a statistical impact on the CO2 emissions, quality of air, and pollution. The argument also declares that immigrants exceed the emissions if they remained in their country of origin since the 1980s decade, and that immigration rapidly consumes environmental resources such as water, air, land, and increases biodiversity loss. This argument has neo-Malthusian, social Darwinism, and racist biases. This paper presents the core debates around the primary premises, the evolution inside the environmental movement in the US. This paper argues that the environmental argument against Latinx immigration lacks generalizable studies, objective data, and scientific validity. The environmental argument evolution has not present enough academic to support to its main claim that connects immigration with environmental degradation. Instead, we argue that immigration it is not the only cause of population growth, the environmental argument denies the strong evidence and studies that linkage environmental degradation with industrialization levels, emissions, economic development, and consumption levels of the US citizens.
