The Pleistocene Park in the Netherlands is looking to fill roles that were prominent before the loss of biodiversity. One big experiment to see what the land used to be like before humans changed the landscape. #iceage#ees028
There could be ecological and economical benefits to #rewilding? the US. Species that used to be here could be used to reestablish important ecological roles, while providing people with the opportunity to experience biodiversity from even before C. Columbus. #ees028
"Re-wilding" N. America would mean setting conservation goals back to 13k yrs ago, when we still had elephants, lions, camels, etc. That is... before humans caused the downfall of megafauna species in N.America #ees028#rewilding?
The Tamiami Trail became a dam, although not its intended use, the levees used to hold back water led to areas that would be dried out for months, causing peat soils to disappear and change the vegetation of the #everglades#ees028
An $18 billion Everglade restoration plan will be completed around 2030. Seen as a vital point in protecting S. Florida's drinking supply, it's a good thing it's aimed to be completed by the year the UN perceives as the deadline to curb climate change #ees028#everglades
A couple rebuilt their deserted piece of land in Aimorés, Brazil by planting 2M tree saplings. As a result, the site has 293 plant species, 172 bird species & 33 animal species, some of which were on the verge of extinction. Took 18 years. https://t.co/kLgkyLP6jA #EarthDay
A year ago the last male northern white rhino died. Sudan suffered a leg infection which led to the decision to euthanize him. During his time at Ol Pejeta Conservancy, Sudan did not reproduce with the two other females, and the subspecies has little hope. #ees028#RIPSudanRhino
The Copenhagen #zoo euthanized a healthy male giraffe in order to preserve the genetics of the population. The decision was highly controversial, and the autopsy of the giraffe was performed in front of crowds and the carcass given to the lions on exhibit as a meal. #ees028
Thought I remember seeing the characteristic fan leaves of the Ginkgo tree on my way to classes in the fall... turns out I was right! #gingkoselfie#ees028
Although the #ferretdrone is a great idea, it has a few kinks that need to be worked out before they are efficient. For instance, if a drone stops working, it needs to be taken apart, fixed and reassembled, which can be time consuming. #ees028
In order to maintain black footed ferret populations, researchers are protecting their food source from a deadly disease by delivering vaccines hidden in peanut butter by drone. I wish we could do the same here for people. #ees028#ferretdrones
Poachers have even attacked zoos in order to obtain #rhinohorn to illegally sell to places such as Vietnam and China. Educating people that this demand could lead to the extinction of rhinos in our lifetime is one of the most important steps to stopping illegal trade. #ees018
All 5 species of rhino are critically endangered due to the illegal trade of #rhinohorn. Seen as a status symbol, rhino horns actually have no more use than your own nails hair. They're made of the same stuff: keratin. #ees028
There are a few speculations to why the #grasshoppersparrow population is declining. For instance, 90% of the prairie, where it lives, is lost to development. Researchers also believe that disease could be behind the low numbers. #ees028
The #grasshoppersparrow is among the most endangered birds N. America with numbers fewer than 150. No one knows exactly why the population is declining. As a last ditch effort, captive breeding is already underway with hopes to reintroduce them into the wild. #ees28
The smog cloud in Donora PA in 1948 came from a zinc plant, which refused to shut down while people were getting sick. This event opened eyes to industrial pollution and its hazardous effects, eventually leading to the Clean Air Act. #smogdeath#ees028
In 1948 in Donora, PA, at least 20 people suffered #smogdeath. The smog created a thick yellow blanket over the town that led to a burning sensation in the throat, eyes, and nose. #ees028
These reduced CO2 levels cooled the climate so much that it crossed a tipping point and triggered the Hirnantian Glaciation. Pretty strong correlation between cooled global climate and low CO2 levels 🤔 #ees038

#climatemyth: CO2 levels have been higher before in the late Ordovician. This is outdated. Recent work shows that the CO2 was actually much lower than thought initially, but more importantly, the solar output was lower back then. https://t.co/SpSt469luy #ees028
Due to the 4% lower than current solar output, the global temperatures were actually low enough to form a continental ice sheet. Furthermore, towards the end of the Ordovician, the development of early mosslike plants provided phosphorus to plankton, both leading to reduced CO2
