Indigenous hunters have positive impacts on food webs in desert Australia. Land development drives animals away from populated areas and changes the conditions of the environment. The biggest impact that humans have on grasslands is by developing open areas for farming or urban development. Furthermore, unsustainable harvesting is to blame. Deserts are also the location where oil and gas are collected for use. "Satellite imagery enables us to look at the age and characteristics of a site's surface geology, which is essential to understanding the rate at which that site will recover from disturbances," said Gaydos. Deforestation removes trees that will take hundreds of years to regrow. Soon after, she also became certified as a Board Certified Pharmacotherapy Specialist (BCPS) to practice as a clinical pharmacist. Why are deserts located along the tropics?
