Explanation:

Ice Age is usually an extended period of low temperature or colder temperature and the spread of glacier. The sea level drops and their is a growth of ice. The answer should be "They make earth 's overall temperature drop hundred of degree".  

Putting paper in the trashcan does not promote environmental sustainability, since there is no recycling,  trees that sustain our environment will be destroyed  to make more papers.

The clean Air Act was created to curb environmental pollution .

Nuclear energy production is a very powerful source of energy but it waste which are radioactive in nature are very toxic to human health. If humans are expose to radioactive waste it might result to deadly disease like cancer.

Smog are caused by human activities . This type of air pollution combines different air pollutant. The major pollutant are particulate matters, sulphur oxides, Nitrogen oxides, ozone and carbon(i)oxide.  Oxygen can be the main component in a petrochemical setting whereby it(oxygen) reacts with Nitrogen oxides and other substance to form ozone in the presence of sunlight.
