“To survive, humans need food, water, and air. Yet biodiversity, the Earth's bodies of water, and the planet's atmosphere are all under threat.” NeedsHumansBodyEarthWaterAirPlanetsThreatAtmosphereBiodiversityBodies Of Water Author:Graciela Chichilnisky
“Even if we planted a tree on every square yard available in the planet by the end of the century we would only capture at most 10 percent of the CO2 we need to reduce. This does not mean that we should not plant trees; we should, for biodiversity's sake, and for our long-term future together with the other species.” IfsNeedsShouldMeanLongDoeEndsTogetherTermTreeCenturyPlanetsPercentPlantSpeciesSakeAvailableLong TermCaptureSquaresYardsBiodiversityPlant A TreeCo2Futures Together Author:Graciela Chichilnisky
“We know little of the consequences of the geoengineering process, such as spraying particles into the atmosphere that shade the planet from the sun's rays and could decrease its temperature. But this process is how dinosaurs disappeared from the Earth about 60 million years ago, by particles spewed by a volcano or a giant meteorite impact, and our species could follow suit.” KnowsYearsLittlesEarthProcessMillionsSunPlanetsConsequenceYears AgoImpactSpeciesSuitsAtmosphereGiantsShadeRaysParticlesTemperatureDinosaursDecreaseVolcanoesGeoengineering Author:Graciela Chichilnisky

“Changing the world's oceans to increase their uptake of CO2, as other geoengineering solutions propose, is equally dangerous, as the increased resulting acidity of the oceans kills tiny crustaceans, such as krill, that are the basis of the pyramid of life on the planet as we know it.” KnowsWorldDangerousPlanetsOceanSolutionsBasesIncreaseTinyChanging The WorldProposePyramidsCo2Geoengineering Author:Graciela Chichilnisky
