Freshwater Ecology and Eutrophication Meeting： Rationale, Objectives and Format

October 11-15 October 2008, Jinan University, Guangdong, China Limnology, although showing progress overall, still has many handicaps: there is a lack of understanding of process and functions, of animal and plant diversity, of taxonomy in some climatic regions like the tropics-subtropics, and the teaching of the discipline is lagging so far behind that in many countries that span several climatic zones,

Human Ecology for Introductory Biology Courses: An Overview

Human ecology, specifically the population—resource—environmentdilemma, should be given thorough coverage in every introductorybiology course. To aid educators in integrating it into thecourse, the subject is outlined here and suggestions are givenon what topics should be emphasized and how they might be introducedto students. Special attention is given to the fundamental roleof population growth in the dilemma, and to the complex interactionsamong population growth, depletion of resources, and environmentaldeterioration. Today's human population size appears to be abovethe long-term carrying capacity of Earth, and is only maintained(albeit often badly) by the exploitation of a "one-time bonanza"of fertile soils, fossil fuels, concentrated ores, ground water,and other species of organisms. If current trends continue,the depletion of these resources will progressively degradethe human environment, destroying the capacity ofnatural ecosystemsto supply civilization with indispensible services. The resultswill be in increasing frequency and severity of disasters, especiallyfamines, that will at first most seriously affect the poor.But the rich will increasingly be impoverished, and be engulfedalso. The basic solution to the dilemma is reduction of thesize of the human population to one well below the long-termcarrying capacity (one living on resource "income" rather than"capital") and establishing an equitable society with a sustainableeconomic system.
