Environmental Science Air Pollution in Cities
There are five primary sources of air pollution that effect big cities. The first form of pollution is
carbon dioxide which results from cars, homes and manufacturing. Nitrogen oxide is emitted
Environmental Science Species Diversity
Earth has a high amount of genetic diversity in organisms. There are lots of species known to
scientist but there are also a lot of unknown species that are waiting to be discovered. Organisms
Introduction to Environmental Science
A scientist makes observations or data collected by the five senses. A scientist makes a
hypothesis and designs an experiment that can be solved by a test. Scientists make predictions

Much of the energy needs in the developing world are met by using bio-mass fuel such as wood.
Developing countries usually do not have access to other fuel sources. Biomass fuel is renewable
but over use can
1 Describe the three main properties of a population. The three main properties are size, density
and dispersion. The size refers to how big a population is. The density refers to how many
organisms are living in a particular area. And dispersion refers t
