Define succession, seral community (or sere), and climax community - succession- the process of change in the species structure and composition of an ecological community over time. It is more or less orderly and predictable changes following a disturbance or the initial colonization of a new habitat. Usually discussed in terms of the plant species, but animal species present change with the changes in plant species seral community (or sere)- an intermediate stage found in ecological suc...

Solid and Hazardous Waste/Environmental Justice ! What are the consequences associated with landfills and incinerators? Landfills: groundwater contamination, methane generation, long-term viability, few new facilities opening and expensive to close Incinerators: though they take up 90% less space and can make steam to turn turbines, they have been wrongfully marked as "green". They are harmful to the environment -- Harmful Air Pollutants (HAPs) which include Carbon monoxide, dioxins,...
