What are some challenges the Earth's population must face as we begin the 21st century?

We have increasing populations, but eventually we will reach carrying capacity where these people are no longer sustainable on Earth. (Think, China, Africa, etc). I already have lack of healthcare, and resource depletion (water, soil, etc).

What are some ways we can take responsibility for ensuring a sustainable future for the planet? What actions can we take?

Thanks in Advance!
