DIA MUNDIAL DA ÁGUA






Hoje, 22 de março é comemorado o “Dia Mundial da Água” em todo o planeta, essa data foi instituída pela ONU_Organização das Nações Unidas em 1992. Por isso, durante toda essa semana iremos abordar temas ligados ao uso e conservação desse recurso.

Essa data, é um marco importante para que se discuta e avalie o papel da sociedade no uso e conservação desse bem escasso para a sobrevivência da humanidade.

Cientistas afirmam que em 2050, 1/3 da população mundial sofrerá com a falta de água potável, e na maioria dos casos, o homem é o principal causador das catástrofes, mas, esses estudos também sugerem que ainda há tempo de se evitar.

O Brasil detém as maiores reservas de água doce do mundo, e estão disponíveis em dois pontos distintos do País, a mais conhecida está na Bacia do Amazonas sendo facilmente visualizado através dos corpos d'água dos caudalosos rios, como o Rio Amazonas, a outra está no subterrâneo, é o Aquífero Guarani, um super poço subterrâneo que cruza sete estados do Brasil e também avançam para o Paraguai e Uruguai, neste aquífero, estudos afirmam que existem cerca de 37 mil quilômetros cúbicos de água potável. O Brasil utiliza apenas 5% desse potencial.

Trazendo a tematica para o ambito local, encontramos um paradoxo para a nossa realidade, apesar de estarmos na maior bacia hidrográfica do planeta, em Manaus falta o acesso universal a esse bem, pois em várias cidades amazônicas, a população não tem acesso a água potável e ao mesmo tempo, observamos a agressão que nossos corpos d’água são submetidos, recebendo dejetos e resíduos industriais, contaminando de forma agressiva o meio ambiente.

Sobre o tema, relatório apresentado na primeira semana de março pelo Fundo das Nações Unidas para a Infância (Unicef) e pela Organização Mundial da Saúde (OMS) aponta aumento no alcance de metas quanto ao acesso à água potável no mundo, mas igualmente indica fragilidades na melhoria da qualidade, da distribuição, do investimento e do saneamento básico.

Dados coletados por Vanessa Ramos em artigo publicado no Portal Rede Brasil Atual publica matéria divulgada pelo Unicef, o relatório intitulado “Progress on Drinking Water and Sanitation 2012” aponta que “só 63% da população mundial tem agora acesso a saneamento melhorado, um número que, segundo estimativas, deve chegar apenas a 67% até 2015, muito abaixo dos 75% almejados pelos ODM (Objetivo de Desenvolvimento do Milênio)”. No mundo, “2,5 bilhões de pessoas continuam sem acesso a saneamento melhorado”,

Vamos aproveitar essa data para refletir como podemos (cada um de nós) contribuir com a conservação desse precioso bem.

  11. First of all I want to say superb blog! I
    had a quick question in which I'd like to ask if you don't mind.
    I was interested to know how you center yourself and clear your head before writing.

    I have had a hard time clearing my thoughts in getting my thoughts out there.
    I do take pleasure in writing but it just seems like the first
    10 to 15 minutes are wasted simply just trying to figure out
    how to begin. Any suggestions or tips? Many thanks!
