I was just having this conversation recently! It is sickening how much food we waste and the consequence of the waste just makes me sad. In the US, we toss out about 150,000 tons of food each day. The majority being produce and then meat. Think about the energy wasted and consequence to our beautiful earth (greenhouse gas). It’ll also eventually effect the price we pay for our food. The implications are vast.
This is a loaded question that digs deep into social fabric issues. The question being how do we keep people accountable for their waste? My thoughts on conserving energy is to cut down food portion size. It's a double solution, that can help the general populace stay healthier and combat waste. With less consumerism there will be less waste. At the same time, by product is also inevitable. Business’ as well as individuals should be mindful of finding solutions to recycle. Things like donating the food to charity, supporting sustainable business’ or coming up with innovative products such as the biodegradable spoon.
It really all comes down to your own lifestyle choice and whether you care enough about your future generations to make those changes. I mean or in 300 years time, technology could possible take humans to the point where we can find subsistence in eating fried metals or some other ambiguous space food. So who cares? But for now, I’ll support the boring, hippy, green movement.
