The world produces more than 2.3 billion tons of municipal waste each year.

That's enough to fill 822,000 Olympic-sized swimming pools.

And with just 16% of it recycled, it all has to go somewhere.

From mega mountains and waves of trash to garbage islands that are twice the size of Texas, let's explore

10 of the largest garbage dumps in human history.

Annually, India generates more than 68 million tons of waste. That's roughly the same weight as 48 million cars.

The city of Mumbai alone produces 2.7 million tons of garbage per year.

That means the city generates a whopping 7,400 tons of trash

every 24 hours. Most of this waste is taken to the Deonar landfill, which stretches across

326 acres of an eastern suburb of Mumbai. The oldest dump in India, the Deonar landfill, was set up in 1927 and has a daily

capacity processing limit of 2,000 tons. But this upper limit is largely ignored as a massive

5,500 tons of trash are regularly dumped at the site every day.

As a result of this chronic overburden, piles of garbage in its vicinity have been stacked

up to 114 feet high.

That's the same height as a 10-story apartment block.

Though it's definitely not a place anyone would want to live, but this trash mountain is still growing.

Back in 2012, the Municipal Corporation of Greater Mumbai had to seek permission from the

airport authority of India to increase the height of the dump to 164 feet. That's about the same height as an 18-story building.

If it grows much higher, soon planes are going to have to start flying around this garbage mountain.

But even then, passengers won't be able to avoid the terrible smell,

although that's not the only thing they'd have to worry about.

As it decomposes, trash releases methane, a highly flammable and foul-smelling gas.
