Environmental Issues:

This is an example of smog. Smog is when an areas air gets polluted. This happens because if the process of burning things like fuel. This process affects animals as well.

This shows how much the world is affected by chlorofluorocarbons (CFC). Chlorofluorocarbons is a very important ingredient to the destruction of the ozone layer. The ozone layer has not been doing well because of all the different gases. One of these molecules would destroy many ozone parts. Another example that does not help the ozone layer is a UV light because it affects photosynthetic algae. This photo represents global warming. This has been happening because of the increased levels of Co2. Scientist are not able to test the hypothesis but they have a evidence to support that Co2 makes the earth produce more energy.

This is acid precipitation. This process happens over time when water and air pollution mix together and they form acid precipitation. This process put an affect on trees because it makes them come down with a disease or makes the trees die.

The pollution of land and water are affected mostly by humans. When humans have things like farms, ranches, stores , homes, and schools they produce a lot of toxins. When toxins go into ecosystems is is called biological magnification.

When humans take on an impact to the air, climate, and land it is part of an ecosystem disruption. With this happening species can disappear and also an entire population of a certain community can go missing.

Extinction is the death of every member in a species. This could happen to any organism if something very bad happens. A way that extinction could happen is it the habitat of the organism was destroyed. When forests are cut down many habitats are lost which makes many organisms have to find new habitats.
