A report from Live Science: Wilderness areas around the world have experienced catastrophic declines over the last two decades, Designwith one-tenth of global wilderness lost since the 1990s, according to a new study.
Since 1993, researchers found that a cumulative wilderness area twice the size of Alaska and half the size of the Amazon has been stripped and destroyed.
The shrinking wilderness is due, in part, to human activity such as mining, logging, agriculture, and oil and gas exploration.
The researchers said their findings underscore the need for international policies to recognize the value of wilderness and to protect wilderness areas from the threats they face.
Central Africa and the Amazon saw the most wilderness decline, the researchers found.
Of the roughly 1.27 million square miles (3.3 million square kilometers) of global wilderness lost, the Amazon accounted for nearly one-third, and 14 percent of the world's wilderness was lost from Central Africa, according to the study.
The researchers determined that only 11.6 million square miles (30.1 million square km) of wilderness is left, which equates to just 20 percent of the Earth's total land mass.
The study was published online in the journal Current Biology.

Don't worry, our oxygen mostly comes from the earth's oceans and not the forest.
Oxygen is produced during photosynthesis and all of the oxygen in
the atmosphere has been produced by photosynthesising plants and
bacteria.
Because rainforests are luscious and fast-growing, it has
become common to think of them as the lungs of the Earth. It is true
that a lot of oxygen is produced there, but almost all of it is consumed
simultaneously.
The growth cycle of
rainforests is so fast that there is no deposition of organic matter -
all dead plants and animals are immediately digested and broken down
into lesser compounds that become nutrients for new growth.
During the
decomposition of organic matter, bacteria and other detritivores consume
oxygen, which is why there is practically no net oxygen production from
rainforests.
The
algae and cyanobacteria in the oceans are small but abundant and,
according to various estimates, they produce about 50-80% of atmospheric
oxygen. That is why the health of the oceans is essential for
sustaining mankind. Carbon emissions also have a role to play - higher
CO2 levels increase ocean acidification which destroys corals, creates
toxic algal blooms and life-free "dead zones".
So,
there's a lot more to life in the oceans.
The microscopic algae and
cyanobacteria provide us with our daily 500 litres of oxygen, without
which we wouldn't be able to survive.
Now here is what we should be concerned about.
The Geoengineering projects are putting chemicals and sulfuric acid into the atmosphere that eventually drop down into our oceans.
As a result the oceans are becoming acidic as well as the soil of the earth.
The algae and cyanobacteria die off and oxygen production suffers.
There are Dead Zones in our oceans and lakes.
The largest dead zone in the world encompasses
the entire bottom of the Baltic Sea.
Others dead zones occur in the
Chesapeake Bay, off the coast of Oregon, Lake Erie, and the most famous
dead zone is located in the Gulf of Mexico.
If we loose our oxygen producers this exosphere ball we live on will become inhabitable.
The military experimenters are messing around with the deep things of our planet and are not concerned with how they are harming the balance of creation.
Christians should not remain neutral, they need to get involved in protecting God's creation.
Radiation flowing into the ocean is still a major factor in creating dead zones.
