These shocking images show piles of rubbish strewn around after being left behind by revellers following the recent heatwave.
Mounds of litter were left sprawled across parks and punts in Cambridge, where hundreds of people came out to enjoy scorching temperatures.
But they had little thought for refuse teams left to clear-up the mess – abandoning bottles, cans and food wrappers in their wake.
'People should have more respect'
Locals were quick to criticise the carnage, which had turned the city's green areas into waste ground.
Joyce Phillips, 49, said: "I understand people want to go out and have a good time in the sunshine, but I don't know why they can't clear up after themselves.
"We are very lucky to have some beautiful parks and green spaces in Cambridge but they get destroyed at the drop of a hat.
"People should have more respect for the area and the workers who have to go out and tidy up to get things back to normal."
Wildlife and vermin
Among the rubbish were used disposable barbecues and discarded meat packaging after people had cooked for themselves in the great outdoors.
Surveyor Tim Price, 53, said: "It's not nice to see the following day. I walk my dog through these areas and she is of course drawn to the smells the packaging gives off.
"Just think what other wildlife and vermin they're attracting.
"It can't be pleasant if you have children either, you expect these places to be safe for them to play in but who knows what they could get into.
"It's just a shame people can't take responsibility for their own mess."
Temperatures in Cambridge rocketed to a tropical 27 degrees last week, making it hotter than Barcelona, Athens and Los Angeles.
The sweltering heat broke records for the hottest April day for 70 years.
Residents donned their sunglasses, slapped on the sunscreen and took to the outdoors.
On Jesus Green by the river, families tucked into ice creams, while others sheltered with a book under the trees.
At Granchester Meadows people also dumped their trash, ruining the beautiful landscape.
Pictures show bottles, bags, discarded crisp packets and even glass across the grass.
The litter sparked concerns that the beloved Cambridge cows may get ill if they accidentally ate any of the trash.
Tourists floated down the River Cam on punts and workers took their lunch breaks on the city's lawns.
However, temperatures are set to significantly plummet this week where they will remain in the mid to high teens over the coming month.
