There are several major ongoing debates and issues affecting the planet as a whole. Here are some of the key ones:

Climate Change: There are ongoing debates around the causes, impacts, and best solutions for addressing climate change driven by human activities like burning fossil fuels. Discussions revolve around balancing environmental protection with economic impacts of mitigation strategies.

Environment and Conservation: Debates continue about how to protect biodiversity, ecosystems, forests, oceans and natural resources in the face of human development, pollution, overfishing and other threats to the environment.

Energy Sources: There are debates over transitioning away from fossil fuels toward renewable energy sources like solar, wind and hydroelectric power to reduce carbon emissions and dependence on finite resources like oil and natural gas.

Food and Water Security: With growing populations, there are discussions about achieving global food and water security through sustainable agriculture, water management, reducing waste and inequalities in distribution.

Global Health: The Covid-19 pandemic thrust global health preparedness and vaccine/medicine access into the spotlight. Ongoing issues also include combating other diseases, healthcare costs and universal healthcare access.

Conflict and Human Rights: Debates persist around handling regional conflicts, distribution of resources, human rights violations, refugee crises and how the international community should intervene.

Technology’s Impact: There are conversations around the influence of technology ranging from automation’s effects on jobs to the ethics of AI, privacy concerns with data collection and social media’s societal impact.

Global Inequality: Issues like extreme poverty, education access, gender equality and the socioeconomic gaps between the world’s richest and poorest nations are part of the global inequality debate.

These weighty issues face no easy solutions but continue to be actively discussed and debated among world leaders, international organizations, experts, activists and the general public. Addressing them will likely define this era for humanity.
