Ecology & Environment Waste Management Biodiversity Ecological Footprint Green Energy Eco-system 1. INTRODUCTION

Eco-system Ecosystems (ecological systems) functional units - interactions of abiotic, biotic, and cultural (anthropogenic) components. Combination of interacting, interrelated parts that form a unitary whole. “Open" systems - energy and matter are transferred in and out. The Earth - constantly converts solar energy into myriad organic products, & has increased in biological complexity over time INTRODUCTION

World map of countries shaded according to their ecological footprint in 2006 (published on 25 November 2009 by the Global Footprint Network). 2. ECOLOGICAL FOOTPRINT

Definition The ecological footprint is a measure of human demand on the Earth's ecosystems. It is a standardized measure of demand for natural capital that may be contrasted with the planet's ecological capacity to regenerate. (Ewing et al, 2010) 2. ECOLOGICAL FOOTPRINT

Ecological footprint shows that if everyone in the world consumed as many natural resources as the average person in Western Europe, we’d need three planets to support us. 2. ECOLOGICAL FOOTPRINT
