The Importance Of The Consumption Of Water In The World
Nowadays, one of the most important issues in the world that concern the human population is the consumption of water. Globally, the water shortage and degradation is a growing concern, since the stocks are eliminated. The main concern is if there will be enough water for the demands within the next 25 to 50 years. As the industrial development and the world population increase dramatically, the demand for water increases too. Today, industries and agriculture are the leading cause of the water’s shortage. The multiple role of water in food production (ingredient, cleaning and sanitation, manufacturing processes) makes its use more than vital.

Another thing that industries must be focused on, is to improve the value chain, from production, post-harvest handling, processing, retailing, consumption to distribution and trade, by addressing strategies for efficient water and food recycling. It can help secure environmental water requirements when reuse of treated water is not culturally acceptable for other uses.
The Omnivore's Dilemma By Michael Pollan
1217 Words | 5 PagesGrazing and growing feed for livestock now occupy 70% of all agricultural land and 30% of the ice-free terrestrial surface of the planet. If these current events continue, meat production is predicted to double between the turn of the 21st century and 2050. Yet already, the Earth is being overpowered by livestock that consume massive quantities of energy and resources, whose wastes contaminate waterways and farmlands, and when eaten excessively, degrade our health.
