of the economy. The present serious environmental problems are largely caused by rapid economic development. For example‚ land resource are shrinking because of industrial environment and the expansion of cites. We excessively exploit nature and ecology‚ which is threading future generation. We shouldn’t sacrifice environment to develop economy‚ because if we sacrifice the environment for economic development‚ we won’t have any clear food‚ pure water and clean air; we will live on the Earth with

These ecosystems are an intricate part of the human lifecycle

Although I was only in third grade‚ the destruction of the environment affected me more deeply than most of my fellow classmates and continues to do so today. I wish to embark on an educational journey to beautiful Montverde‚ Costa Rica for the Tropical Ecology and Conservation program in the Spring of 2009. In order to take this step in my educational career‚ I am applying for financial aid through the John E. Bowman Travel Grants‚ CIEE International Study Programs Scholarships‚ and the Jennifer Ritzmann

By the same token‚ the Mexican wolf was subsequently thrown into endangerment due to improper conservation evaluations and lack of ecological research. This goes to show that ecology has come a long way since the nineteenth century‚ and has ultimately worked its way toward better scientific evaluations and stricter conservation

Introduction Ecosystem is similar to a community. It consists of species‚ living organisms and the abiotic factors‚ their habitat. Living organisms includes animals‚ plants‚ insects‚ micro-organisms. For their habitat‚ they are the non-living nature which are soil‚ sunlight‚ water‚ precipitation. There are two types of ecosystem. Terrestrial ecosystem which is on the land and aquatic ecosystem which is under the water. Over-breeding is the increase of offspring of a species to a excessive number
