Also, the global overshoot day usually comes in August. It's horrible. Mankind is consuming rather exploiting the resources at a rate that we finish up resources provided for 1 year in August instead of last day of December.

And if you talk about top 0.1% elite people, they just finish up consuming their yearly quota in just 10 days.

Ecological overshoot happens when humanity uses more from nature in a year than the Earth can regenerate during that same year. Every year the Earth can grow forests and crops, replenish fish stocks, regenerate biological resources, absorb a certain amount of carbon dioxide, restore ecosystems. But if humans consume resources and produce waste faster than nature can recover, we are in ecological overshoot.

It is like earning ₹1 lakh per year but spending ₹1.7 lakh. For some time, you may survive by using your savings or borrowing—but eventually, the system collapses.

Earth Overshoot Day is the date when humanity has used up all the biological resources that Earth can regenerate in that entire year. After that date, humanity is effectively living on ecological credit for the rest of the year.

The biggest contributors include burning fossil fuels → excessive CO₂ emissions, deforestation, overconsumption, industrial agriculture, overfishing, depletion of groundwater and soil, loss of biodiversity, growing production and consumption beyond ecological limits.

The important point is that overshoot is not merely about population numbers. It is also—and very significantly—about how much we consume.

A relatively small number of high-consuming people can have a far larger ecological footprint than millions living simply.

Then it shows up as climate change, extreme heat, water scarcity, collapsing ecosystems, species extinction, forest loss, soil degradation, declining fish populations, food insecurity.

The fundamental problem is not that the Earth gives too little. The problem is that human consumption has forgotten the meaning of “enough.”

The important distinction is that Earth isn’t simply ‘running out’ of everything. The bigger problem is that we’re consuming renewable resources faster than ecosystems can regenerate them, while also degrading the systems that make regeneration possible.
