How are human activities distributing carbon dioxide levels and affecting marine life?

The manufacturing of oil and gasoline, carbon dioxide emissions, and waste management are all contributing factors to the rising CO2 levels. The rising levels have caused ice burgs near the poles to begin melting which rises the sea levels. The oceans are also warming up and animals struggle to adapt quickly enough. Pollution in the oceans also negatively affects marine life and causes red tides which are detrimental to all plant and sea life.

All of them are man made
