World Environment Day (WED) once again will be celebrated around the world this Wednesday, June 5th. The theme for this year's WED is Think.Eat.Save. Think.Eat.Save is an anti-food waste and food loss campaign that encourages you to reduce your foodprint. Given the enormous imbalance in lifestyles and the resultant devastating effects on the environment, this year's theme – Think.Eat.Save – encourages you to become more aware of the environmental impact of the food choices you make and empowers you to make informed decisions.

If food is wasted, it means that all the resources and inputs used in the production of all the food are also lost. For example, it takes about 1,000 litres of water to produce 1 litre of milk and about 16,000 litres goes into a cow's food to make a hamburger. The resulting greenhouse gas emissions from the cows themselves, and throughout the food supply chain, all end up in vain when we waste food.

In fact, global food production occupies 25% of all habitable land and is responsible for 70% of fresh water consumption, 80% of deforestation, and 30% of greenhouse gas emissions. It is the largest single driver of biodiversity loss and land-use change, according to WED's guidance materials.

WED is celebrated each year to raise awareness of the need to take positive environmental action. It is sponsored by the United States Environment Program (UNEP).

In recognition of WED, many of our blogs this week will address food waste, sustainable consumption and the environmental impacts of agriculture and food processing.
