At the actual population growth rate, human activities threaten the future of Earth.
In the last century humans had polluted or over-exploited most ecosystems on which life depends.
The major issues that Earth is challenging now are:
-Population increase rate is higher every year: How can limited resources feed all the people?
-Endangered species: can we save them? Or there will be another massive extinction?
-Water scarcity: as population grows, the use of clean water grows, how do we solve this issue?
-Energy Demand: How can we provide enough energy to an increasing population without damaging the environment?
-Pollution: in a planet that's more polluted everyday, how can we get fresh air, food and clean water?
-Global Warming: How do we stop higher temperatures, rising sea levels, and who knows what unpredictable weather issues like another Ice Age?
What can be done to reverse all the above?
