How many people can our planet really support?

We have a problem with the future of the planet. The problem not is the number of people if not the behavior of these persons with the Earth. This happens because we consume more than earth produces.
As Gandhi said " The world has enough for everyone's need, but not enough for everyone's greed"
The population increases and with she the damage that we make with our necessities. According to United  Nations predictions it could reach 9 billion people by 2050, and over 11 billion by 2100. And more important we aren't know if can live so much persons because this never happened before. But we can know where will happen this increase observing that the largest increase currently low and middle-income countries.
Mainly, rich countries emit the emissions of carbon dioxide and other greenhouse gases however the poor countries even having more inhabitants emit less greenhouse gases. There are exceptions, such as the Copenhagen.
The way for can to maintain a large human population is that the people living in high-income nations reduce the pressure on global climate.
Therefore, there needs to be a fundamental change in the core values of developed societies: away from an emphasis on material wealth, and towards a model where individual and societal well-being are considered most important.
Also is important reduce the number of inhabitants because we aren't maintain so much persons. A good method is helping the persons of poor countries because sometimes have sons because they haven't contraceptive methods and when have the son they can't maintain him.
The big number of inhabitants and the actions of these make: problems of climate change, biodiversity extinction crisis, mass ocean pollution, one billion people are starving and another one billion people are having nutrient deficiencies.
Although it has been investigated if we would can live in other planets, for the moment the only place where we will live is the Earth. Then we have to take care of the Earth.

I think that the rich countries we would have to something for attempt to improve the condition of Earth and the some inhabitants of this. Until not make nothing globally we can make anything for helping to Earth.
