RESUMO

O presente trabalho apresenta uma revisão bibliográfica e opiniões sobre as intervenções do ser humano no meio ambiente e as suas consequências para a humanidade e o ecossistema. Foram abordados aspectos como o problema energético, o efeito estufa, o conteúdo de CO2, o papel dos oceanos e suas alterações, o ciclo do carbono, bem como princípios para a redução de CO2, de oxidantes e do ozônio. Também foi enfocada a importância das florestas como redutor do CO2 e aspectos gerais pertinentes ao uso adequado do meio ambiente.

Palavras-chave: meio ambiente; poluição; efeito estufa; reações climáticas

ABSTRACT

The present work is based on bibliographical review and opinions about man’s consequences for mankind and the ecosystem. The article deals with aspects such as the problem of energy, glass-house effect, the content of CO2, the role of oceans and their alterations, the carbon cycle as well as the principles for reducing CO2, oxidants and ozone. It was also highlighted, the importance of forests as a reducing factor of CO2 and other general aspects related of the proper use of the environment.

Keywords: environment; pollution; glass-house effect; climate
