8. The Disadvantages of Coal Are Significant. 1. It Increases Carbon Dioxide in the Environment. Why Coal Ain’t Cool: 7 Disadvantages of Coal You Need to Know. When we burn coal, it produces extra carbon dioxide, or CO2. CO2 causes a “greenhouse effect,” which means it makes the planet retain more heat in the lower atmosphere.

The good, the bad and the ugly about ocean iron

Jul 11, 2019 The good. Ocean iron fertilization has a number of benefits. When you release iron particles in the water they feed the algae. These then bloom and absorb the harmful carbon dioxide for carrying out photosynthesis. These tiny pieces of iron then sink in the ocean and lock away the hazardous gas for upcoming years.

4 Disadvantages Of Neural Networks Built In
