A atual fase da relação do homem com a natureza chegou num período crítico. Os problemas ambientais de ação global vêm ganhando proporções assustadoras. Estudamos três deles: O efeito estufa (aquecimento global), a destruição da camada de ozônio e a chuva ácida.Percebemos que a utilização de fontes de energia a partir de recursos naturais não-renováveis – como os derivados do petróleo, por exemplo – é a grande causadora de tais problemas e, com o aumento populacional, tende a aumentar essa utilização por parte da humanidade.Porém, sabe-se que uma das possíveis soluções para esse caos ambiental pode ser o investimento em fontes de energia renováveis. Sobre essa possibilidade (e agora que já estudamos sobre o assunto) você está convidado a emitir sua opinião através dos comentários.A atividade consiste nos seguintes procedimentos:1 – Pesquisar e estudar sobre o assunto “Fontes de Energia Renováveis” com o apoio do livro didático de Geografia (essa parte está cumprida e, inclusive, você já respondeu a um questionário). 
2 – Participar, através de comentários no blog GEOSAL, de um debate virtual (até o dia 10.06). Você deve colocar suas impressões sobre o assunto, concordar ou discordar de seus colegas (sempre num nível educacional!) e o que mais achar interessante. Emita sua opinião de maneira crítica, aponte os pontos que você considerar positivos e negativos dentro do assunto. 2.1 – Sempre se identifique ao final do comentário (nome, turma e turno). Comentários anônimos não serão aceitos.2.2 – Ao se referir a algum colega coloque o nome e a turma ao qual ele pertence, faça seu comentário e se identifique no final.2.3 – Comente quantas vezes quiser.
Mãos à obra! Bom trabalho!
