Final answer:
Exponential population growth poses environmental and resource challenges, necessitating sustainable development and population control measures. Efforts to reduce greenhouse gas emissions face international agreement challenges, leading to uncertainty in maintaining Earth's carrying capacity.
Step-by-step explanation:
The exponential population growth the world is experiencing presents significant challenges, including environmental degradation, climate change, and resource depletion. Sustainable development and population control are essential to mitigate these issues. Several potential solutions include implementing family planning, educating women and girls, and reforming economic policies to encourage sustainable practices. Meanwhile, countries are trying to reduce greenhouse gas emissions to combat climate change, but international agreements are hard to achieve. The uncertainty of successfully managing population growth and environmental protection raises concerns about our ability to maintain the Earth's carrying capacity for human life.
