What is constructed on or taken from the land will most certainly have an impact on ecological systems. What is extracted out of the Earth and harvested in the landscape will have ecological impacts. What is consumed for energy will have impacts and affect the balances on the air, water, and land. All construction, extraction, harvesting, and consumption of the Earth’s resources will affect the health, safety, and welfare of the world’s ﬂora and fauna, including humans. These human activities have affected and will continue to affect the quality of the Earth’s resources, reduce biodiversity, increase the frequency and strength of natural disasters (hurricanes, ﬂoods, air pollution), and greatly alter (deteriorate) the quality of lives of future generations unless we reduce if not eliminate our detrimental exploitation of nature.
