With the exception of the islands and a handful of small cities on the east coast, the land in which most of the world’s people live has been largely unchanged for centuries.
But that’s changing rapidly as climate change pushes the Earth to the brink of potentially catastrophic extinctions.
The first such event occurred about 100,000 years ago when the first human beings appeared on the scene.
Over the next 10,000 or so years, climate change began to push our planet to extremes, forcing humans to move farther north, farther east and farther south.
The next event, about 12,000 to 12,500 years ago, saw an even more drastic shift in the Earth’s environment.
This event caused widespread famines, major population migrations and massive changes in the climate.
In the modern era, climate has been a major driver of species extinctions and species extinction risk.
Scientists think it’s because the Earth has become more vulnerable to catastrophic climate change, especially when the Earth is in a low-lying state.
The oceans are more acidic and the atmosphere more acidic, which means the Earth holds more carbon dioxide in the atmosphere and less carbon dioxide is available to decompose.
As a result, the Earth can’t support many of the organisms that it was designed to support.
This means species that once thrived in those habitats, like fish, are dying off.
The result is that some species are losing a great deal of their habitat.
In this study, scientists from the Smithsonian Tropical Research Institute (STRI) at the Smithsonian Institution and the University of Alabama at Birmingham (UA) analyzed the distribution of species in land, sea and water around the world.
They found that the areas in which species are concentrated have changed drastically in the last 10,500 to 12:00,000 yrs.
They discovered that over the past 1,200 years, there have been over 2.5 million species of land plants and animals gone.
This makes it one of the most important areas in the world to study in terms of biodiversity change.
Scientists believe that these changes have been driven by changes in temperature, rainfall, salinity and ocean acidity.
They also note that the effects of climate change are cumulative and can have far-reaching impacts on biodiversity.
This is especially true when considering the effects on species in the tropics.
These changes are occurring as temperatures increase, sea levels rise and rainfall patterns change, all of which have a direct impact on species that are not adapted to them.
For example, the changes in salinity can make it more difficult for fish to get enough nutrients, making them more vulnerable and thus less able to survive.
In addition, the changing ocean acidification can affect plant and animal populations, making the ocean more vulnerable, which leads to the extinction of some species.
The change in vegetation in this region is an example of how climate change is affecting biodiversity.
We know that tropical forests, or tropical ecosystems, are a major habitat for many species, but until recently, we didn’t know exactly what plants were in those ecosystems.
The new study found that there are a lot of species living in tropical forests.
The results were so unexpected that the researchers had to re-examine the way they analyzed the data.
What they found is that we can actually reconstruct how many species there are in tropical ecosystems and how many are living there, in a way that is not possible with only the topographical data.
For instance, in the U.S., there are about 4.5 billion species in tropical and subtropical forests, but only 2.8 billion species are living in the forests.
That’s because there are only so many places to plant trees in a forest, so you have to plant in a large number of places in order to make a tree grow.
The researchers also found that it’s difficult to determine which plants are in the forest, because the trees are always changing location and species are moving around.
They found that while tropical forests were the primary habitat for a number of different species, other ecosystems were more important to the majority of the species that were in the topography.
For this reason, tropical forests are the preferred habitat for some species, whereas the majority is found in other habitats.
While these changes are happening on a global scale, there are also many examples of species moving from one location to another as they move between the tropic and temperate zones.
For some of these species, such as the blue whale, there is a very good relationship between the two, where in temperate forests they move from warmer habitats to cooler habitats.
This can be because species in temperates need warmer temperatures to live, which in turn makes it easier for them to survive in the cooler areas.
In addition, some of the smaller species, like the blue whales, may not be able to get a foothold in the temperate areas because of the high salinity of the oceans.
This may make it harder for them
