The Maldives growth happened because sand was pumped from the seafloor to a lagoon for creation of an artificial island. https://earthobservatory.nasa.gov/images/148158/preparing-for-rising-seas-in-the-maldives They did that to prepare as sea levels have been rising. http://www.climatedata.info/impacts/sea-levels/maldives/ The trend is not their friend.
More ozone is OK. Life on earth depends upon it to protect from the sun. Less ozone is not good. More CO2 is OK. Plant life depends upon it. Humans depend upon plant life. Not enough CO2 is not good. LACK of these is the problem. More CO2=more plant life. One video I posted talks about how plant life has INCREASED. One of the videos I posted shows the minimum level of CO2 needed. The important part of the video you quoted is that humans are responsible for only 3% of the CO2 in the atmosphere. We almost don't matter.
NASA's observations of Earth's greening have been confirmed, but parsed, and it's clear most of the greening is the result of humans cultivating increasingly marginal land, and the planting of tree plantations. The rest is ice and snow retreating earlier in the high latitudes. There is some significant but smaller share that can be attributed to more leaves. However... We're not talking about larger harvests of cereal grains, upon which civilization depends. And because we're overcropping we're also not talking about larger harvests with growing or even stable nutrient density. No, we're growing more of lower quality (by throwing more fossil fuels at the process, ironically). Finally, I'll just point out that while greenhouse operators do inject CO2 into their facilities (which by the way are not in drought or flood conditions) to boost growth, they also vent their greenhouses of excess heat.
