Environmental Pollution
The introduction of harmful substances, materials, or energies into the natural environment that causes adverse changes to ecosystems, living organisms, and human health.
Environmental Pollution
Environmental pollution represents one of the most significant anthropogenic challenges facing our planet, occurring when contaminants are introduced into natural systems at rates exceeding their ability to be dispersed, absorbed, or recycled.
