Almost fifteen percent of the Earth’s land is enclosed in national parks or other protected areas, which accounts for approximately 20 million sq km. This figure is close to an internationally agreed goal to protect 17 percent of the land surface by 2020. Comparatively, ocean conservation only accounts for 4 percent of total surface of the ocean, covering 15 million sq km. In spite of these statistics – which reflect a positive outcome of the increased attention and importance given to land and ocean conservation – there are concerns over how well these areas are managed and whether they effectively protect endangered species, as Seth wrote a few days ago.
A progress report by the UN Environment and the International Union for Conservation of Nature (IUCN) warns that some of the most biodiverse ecosystems are not being protected and that the management of many protected areas is deficient.

Last spring the U.S. Energy Information Agency (EIA) predicted that natural gas would generate more power in 2016 than coal, and now that natural gas has taken that lead, it is under close scrutiny as a “cleaner” alternative to coal. From the EIA’s latest Short-Term Energy Outlook, natural gas also beat out coal for carbon dioxide emissions from power generation.
“Energy-associated carbon dioxide (CO2) emissions from natural gas are expected to surpass those from coal for the first time since 1972. Even though natural gas is less carbon-intensive than coal, increases in natural gas consumption and decreases in coal consumption in the past decade have resulted in natural gas-related CO2 emissions surpassing those from coal.”
And the agency isn’t talking in fractions of a percentage point, either. EIA puts the emissions figure for natural gas at 10 percent greater than coal for 2016.

Compared to “juicy” pop culture news, nature-lovers and conservationists constantly have to fight for people’s attention on subjects like endangered animals or protected wildlife. However, the struggle for plant devotees to garner people’s interest on green eukaryotes is much more difficult, except maybe for some garden-popular flowers and vegetables, and perhaps a few trees, but otherwise plants go unnoticed.
Conservation efforts are devoted overwhelmingly to animals; compared to the hundreds of plant species easily found but mostly overlooked in our environs. There’s even a formal name for this: plant blindness. And in a study published in the journal Conservation Biology, biologists Kathryn Williams and Mung Balding of Australia’s University of Melbourne ask whether it’s inevitable: Are people hard-wired by evolution to ignore the vegetal world? Can something be done about it?
“We are absolutely dependent on plants for life and health, but so often they fade into the background and miss out in the direct actions we…

A new study on plant water retention from the University of California, Irvine and the University of Washington might rescind some of our assumptions of climate change impacts on agriculture, water resources, wildfire risk, and plant growth. Their findings reveal that water conserved by plants under high CO2 conditions compensates for much of the effect of warmer temperatures, which means more water is retained on land than predicted in commonly used drought assessments. ScienceDaily reports:
The study compares current drought indices with ones that take into account changes in plant water use. Reduced precipitation will increase droughts across southern North America, southern Europe and northeastern South America. But the results show that in Central Africa and temperate Asia — including China, the Middle East, East Asia and most of Russia — water conservation by plants will largely counteract the parching due to climate change.
