There is a constant tug of war, between developed countries which are encouraging developing countries to continue to protect their wildernesses, and the developing countries wish to be able to develop – to lift their citizens out of poverty.
In one shot: soy farming at the front, rainforest behind and you can see cattle grazing areas at the back
The Pyrennes in the south west of France, and the corresponding area across the border, are a wonderful area of wilderness. There are currently about 64 bears living in this area. So where are we on the road to recovery?
Were the the entire Pyrennes mountains wild, it is thought that these mountains could support 600 bears. However, this area is not an area that is set aside for wilderness – there is a whole population of humans living in these mountains (almost 700,000 people live here).
It is thought that the bear population of the Pyrennes could potentially get to 250 in its current form.

Even 20 years after its discovery, scientists were still arguing about whether it was real. The anatomist Robert Knox claimed if was a “freak imposture”, and that ”the scientific [community] felt inclined to class this rare production of nature with eastern mermaids and other works of art.” This was not only due to its weird appearance, but several other fake animals that had come to light in recent times.
Yet it was not,
To be sure, it is a mammal which perhaps stretches the definition more than most. It lays eggs, has a ducks beak, but feeds its young on milk. It is one of the many oddities that live in Australia.
Unfortunately it is facing local extinction, in many places across its range, and has lost a quarter of its range in the last 30 years..
This is a species that could quietly slip towards extinction without being noticed – being shy, nocturnal and not splashing, they are rarely seen. Most people who do not see one, might suggest that they simply did not get lucky.
There are a range of threats that are pushing them towards extinction. Water extraction from rivers and creeks, the building of dams and weirs, as well as river bank erosion. Increasing regularity of droughts also threaten their long-term survival as their homes become too shallow – allowing feral cats and foes to attack them.
They are capable of living alongside humans – the video above is in the Suburbs of a city, but as pollution increases they often disappear.
The lead author of the study concludes that the Platypus is not facing complete extinction, but local extinction in many different parts of Australia.
So, Jair Bolsonaro and Luiz Lula de Silva have both made it through to the final round for the presidency.
However, the fact that this new deforestation data board was set up 3 months ago, in the run up to an election. This at a time when Jair Bolsonaro is being hit for his terrible record on deforestation during his first term. In other words, people are claiming that this is purely a political organisation to help him pull the wool over the countries eyes.
The decline in African Lions has been pretty constant and totally devastating. Just 100 years ago, there were about 200,000 lions in Africa (some estimates suggest as many as 500,000 in 1950, and 200,000 as late as 1975.
While the Cheetah has suffered a horrific fall in range and numbers in the world over the last century, there are some hopes for the species.
Cheetah are not big cats- this means that they often struggle to thrive in small reserves alongside other big cats. What this has meant is that in many countries there are more cheetah outside reserves than inside reserves. This is primarily the case in Southern Africa, in particular Botswana, Namibia, South Africa and Zimbabwe where the most free ranging cheetah currently live. To a lesser extent, there are also free ranging cheetah in east Africa in Tanzania and Kenya.
Mangrove trees are essential in many parts of the world. Having been severely depleted in recent decades, the human race has realized their importance late, as ever. From stabilizing shore lines, and stopping excessive loss of sand into the sea, they also seive much of our pollution out of the water.
Coral reefs are really important. While they only cover a small area (under 1% of the earths surface area) they support about 25% of all marine life, including more than 4000 species of fish.
Rainforests are incredible places, with a huge amount of wildlife and plants all living closely together and fighting for survival.
Now the problem in many parts of the world, rainforests are being cut down for space to be given over to all sorts of other land uses. I have no problem with some of the rainforests being cut down for other land uses. Unfortunately though in the Amazon, there is a significant issue.
Rainforests are essential for many different things. At the moment, we (as the human race) are concerned about rainforests for their capacity to store carbon – thereby reducing the amount in the atmosphere and therefore the threat of carbon dioxide causing the greenhouse effect.
The problem is, that even without cutting any more rainforests down, we have already changed the weather dramatically. If rainforests are cut down there may then not be enough rain to sustain regrowth. One example is the Amazon, where it is predicted that half its rainfall is caused by the forest itself.
In the Amazon, Congo and even south-east Asia, there are already worrying signs in particularly highly deforested areas, that the rainforest weather is drying, turning the forest into a more savannah like area.
What is clear, is that a fragmented rainforest is deeply threatened. We need large blocks of unbroken rainforest if the planet is to survive in a form that we will continue be good for the human race to continue to thrive within. Of course, this is also essential for the many planet services that the human race requires to keep going.
Of course, this is not a reason to be allowed to cut down the fragments, it is a reason to not create the fragments in the first place. What is important to realize, is that many of the activities that the rainforest is being cut down for, will not work without the rain that the forest creates.
