三、閱讀測驗Environmental abuse occurs as humans violate basic principles of ecology. Polluting the air and water,spreading radioactivity into the atmosphere, increasing levels of noise, creating numerous wastes, and consumingirreplaceable resources—all affect the global ecosystem. Since human beings are part of the ecosystem, we are tooaffected by these activities.There are a number of major types of environmental abuse. Air pollution is known to have harmful effects onhealth and property. Pollution of water brings the threat of disease, shortages of clean water, and destruction ofaquatic life. Nuclear power poses dangers of radioactive contamination. Solid wastes, many of which are notbiologically decomposable, accumulate. Noise and visual pollution are on the increase, the former affecting healthand both harming the appeal of our environment.Land is being lost to misuse, often to the detriment of vegetation and wildlife. Finally, irreplaceableresources—e.g., energy-producing fuels and ores crucial to manufacturing—are facing rapid depletion. Conflictover scarce resources — many of which are located primarily in poor Third World countries—promises to emergein the future.
