As the global consequences of human activity have become unmistakably pressing, Burtynsky has connected his photography more directly with environmentalism.
Rather, our quarrel lies with the acceleration of this process as the result of the improper treatment of species; our goal is the mitigation of the environmental consequences of human activity.
Although plant productivity for the globe has remained more or less constant, he and his team have observed regional differences that reflect the consequences of human activity, he added.
"When he did talk about his motives, he said, 'I am not out to tell people a unitary story about what they should do to save the earth but, rather, to give people a picture of what it takes to live the way we do.' " Over the years, as the global consequences of human activity have become unmistakably pressing, Burtynsky has connected his photography more directly with environmentalism.
LULC analysis has become a fundamental tool in assessing the environmental consequences of human activity (Hunt and Ditzer 2001; Veldkamp and Lambin 2001; Brown 2003; Dunn 2004; Wang et al. 2007; Liu et al. 2011, 2012).
There are also other more indirect consequences of human activity that may perturb marine carbon inventories [30], such as changes in fluvial sediment delivery to ocean [55], as well as climate change-driven ocean warming, deoxygenation, and acidification [20].
The need for such a label did not emerge recently, however; scientists and environmentalists have cautioned of the ecological consequences of human activities for years.
As never before, we must understand the consequences of human activities for the Earth's atmosphere, the oceans, the solid Earth, and the organisms that live on it.
There are many causes of groundwater pollution; most are the accidental or incidental consequences of human activities (e.g., pollution resulting from the use of artificial fertilizers or saltwater intrusion into coastal aquifers due to excessive pumping).
