So what made the difference in the Sahara? Phoenix had been the second highest U.S. city for ozone pollution behind Los Angeles. The potential effects on plants and other organisms due to the decrease in human activity is a bit speculative right now. If livestock are allowed to graze in areas where wild animals live, they compete for the food source and can deplete it. Early Neolithic farmers of northern Europe, China and southwestern Asia are documented as significantly deforesting their environments. How can the impacts of climate change be managed? The " African Humid Period " or "Green Sahara" was a time between 11,000 and. Some negative ways that we are impacting the desert are climate change, overuse of underground water, and soil poisoning. Table 3 The culture results for selected isolates from camel milk in different conditions.
