We couldn’t live without plants

For people there are three necessities of life: clean air, clean water and healthy food. Numbers one and three are directly linked to plant life, and number two is very closely related to plant life. Because plants produce oxygen, clean and retain water, and plants form the basis of our entire food chain. They do this very silently and continuously, as result of which we often tend to forget that that quiet tree, or that pretty little houseplant is actually working very hard for us indeed. Humans and animals use the oxygen O 2 in the air for their energy process and produce CO 2 as waste.

Enhanced growth of Earth's leafy greens during the 20th century has significantly slowed the planet's transition to being red-hot, according to the first study to specify the extent to which plants have prevented climate change since pre-industrial times. Researchers based at Princeton University found that land ecosystems have kept the planet cooler by absorbing billions of tons of carbon, especially during the past 60 years. The planet's land-based carbon "sink" — or carbon-storage capacity — has kept billion to billion tons of carbon out of the atmosphere since the midth century, the researchers report in the Proceedings of the National Academy of Sciences. From the s to the s, land use by humans was a substantial source of the carbon entering the atmosphere because of deforestation and logging. After the s, however, humans began to use land differently, such as by restoring forests and adopting agriculture that, while larger scale, is higher yield. At the same time, industries and automobiles continued to steadily emit carbon dioxide that contributed to a botanical boom. Although a greenhouse gas and pollutant, carbon dioxide also is a plant nutrient.

Forgive the bad play on words, but one of this Sunday's episodes of Life over on our big brother Discovery Channel that's 8pm ET by the way is all about this planet's vast plant kingdom and all the different challenges they face: Struggling to get enough sunlight, making the most out of available water, turning carnivorous and luring animals to their doom. Here on TreeHugger though, much of our plant coverage focuses on human's interaction with them: photo: World Resources Institute via flickr. Eastern US Forests Show 'Significant' Declines in Past 40 Years Though the trend for much of the 20th century was towards more forest cover in the eastern US, with trees reclaiming land formerly used for agriculture, new research shows that in the last 30 years of the century that trend reversed as timber, urban expansion and coal mining took their toll. Since , the east coast saw a 4. The trouble is, the financial gains from converting lands from forest to other uses are short-lived. Research in the Amazon shows that once some initial gains are made, both communities and the forest languish.
