I think the basic problem with increasing populations and sustainability is that there is truly a lack of understanding on what exactly population dynamics is. While many less developed countries are continuing to be characterized by their rapid population growth, other trends have shown that more developed countries are experiencing rapidly aging populations. With a growing gap between more developed and less developed nations, there has also become an increasingly complex pattern of immigration and high rates of urbanization. A big problem that we face is understanding how to meet the needs and expectations of rapidly growing populations while simultaneously altering the current "production and consumption" patterns to achieve more sustainable development. It's important to understand that population dynamics affects both national and global developmental agendas with increasing pressure on natural resources. I think that it becomes even more complex if we think of population dynamics as not only a cause, but also as an outcome of social, environmental, and economic changes. If we want to find a solution for increasing populations and decreasing sustainability, we need to understand that population dynamics are essentially the result of individual choices and opportunities. We should work together on a global scale to expand people's choices and resourcefulness by adopting policies that promote gender-responsive and rights-based policies (i.e. universal access to reproductive/women's health, family planning, and education).
