Christmas for many around the world is a time of plenty: stomachs full to bursting and gifts spilling out from beneath the tree as we indulge those we love.
But in the days that follow, who hasn't felt a slight twinge of guilt at the food we scrape into the bin or the old gadgets that are now going to gather dust in the cupboard or end up on the scrapheap?
Don't worry, though, for there are plenty of things you can do to dispel these nagging worries post-Christmas and in the process contribute to solving some of our most pressing environmental issues, as well as save yourself some money in the process.
The environmental concerns in question are those of food and electronic waste. While the last few decades have seen massive strides taken in recycling items such as paper, glassware and tins, these two areas have been left behind.
A report released this month by the Solving the E-Waste Problem Initiative (StEP) predicts that e-waste will increase by almost a third to 65.4 million tonnes annually by 2017.
This waste - old refrigerators, televisions, mobile phones, computers, monitors and other electronic products - would fill a line of 40-tonne trucks that, sitting nose to tail, would stretch three quarters of the way around the Equator.
E-waste can also pose health risks. The World Health Organization lists related hazards such as direct contact with lead, cadmium, chromium, brominated flame retardants or polychlorinated biphenyls (PCBs); inhalation of toxic fumes; and the accumulation of chemicals in soil, water and food.
Meanwhile, the United Nations Environment Programme (UNEP) and its sister organizations, such as the Food and Agriculture Organization of the United Nations (FAO) in their Think.Eat.Save - Reduce Your Foodprint campaign this year revealed that one third of all food produced each year - equivalent to 1.3 billion tonnes - is lost or wasted annually.
Around 300 million tonnes of this food is discarded by producers, retailers and consumers - this food would be more than enough to feed the estimated 870 million people who face hunger each day across the globe.
Not only that, but this uneaten food requires energy, water, fertilizers and land to produce. Much of it ends up on landfills, where it decomposes and releases the potent greenhouse gas methane.
So, now that you have a better idea of the scale of the global challenges, why not play your part over the festive season and beyond?
While the problems are not easy to solve, there are many simple actions each one of us can take that will in no way spoil our enjoyment of the festive season but will contribute to more sustainable and green choices.
