If we no longer can get certain plants, how may that hurt us?

Back 30

Many medicines will not be able to be made or maybe not even discovered.

Front 31

How can destructions of ecosystems have a negative impact on our lives?

Back 31

Loss of habitats may lead to extinction of different species.

Front 32

What happens when oil tanks are routinely flushed out?

Back 32

Add a lot of oil to the ocean. Oil is poisonous.

Front 33

What makes a substance "hazardous"?

Back 33

It is either poisonous, capable of producing explosive or toxic gas
capable of corroding steel, or
flammable

Front 34

ist four heavy metals that are often contaminates.

Back 34

copper, lead, mercury and selenium

Front 35

How do heavy metals get into water sources?

Back 35

industrial waste, car exhaust, mines and from soil.

What is a natural resource?

Back 36

A naturally occurring materials such as coal, fertile land, etc, that can be used by man

Front 37

What makes at substance plastic?

Back 37

- Plastic is any man-made organic polymer. While plastics may be made from just about any organic polymer, most industrial plastic is made from petroleum.

Front 38

Define mineral.

Back 38

A natural substance of commercial value, such as iron ore, coal, or petroleum, that is obtained by mining, quarrying, or drilling.
