Biology Practice Test on Environmental Issues- Pollution and Green house effect

Population explosion, technological advancements and socio economic activities, such as urbanization, intensive agriculture and massive industrialization  are the major contributing factors of environmental pollution.

Greenhouse effect and ozone depletion are the two major environmental issues. The increased amounts of green house gases in the atmosphere are affecting the global climate. The climate change will increase threats to human health. Global warming will lead to changes in weather patterns and ocean currents.
