Humans change things. They have been doing this in measurable ways within individual ecosystems and globally for the last 14,000 years. The places that humans change/modify/alter (for better or for worse) becomes part of what has been called the 'anthroposphere'. More humans means more change. This space is dedicated to helping you discover how the basic 'environmental systems' that all living things depend upon have been and are being changed by human activity. As human technology becomes more evolved, such as the greater ability of technology to cause deforestation, the impact of human activities on the essential environmental systems could potentially increase, impacting Earth's most unique quality, it's biodiversity .
