Before and after (after being above) image of a river in the Amazon rainforest
Why is this a problem? Well there are several issues that should concern everyone. The natural end of the line, is for the complete loss of the Amazon rainforest. There is much fear that it may be another tipping point, and that therefore, once the rainforest starts failing, it would accelerate the loss of the rest.

For indigenous communities, killing dingoes are a cultural icon, and for them killing them is tantamount to killing a family member.
This has been raised more forcefully, after recent surveys showed that the Australian dingo is actually genetically very pure.
Given their classification of being native species, they should not be culled.
It is true that there is some question as to when the dingo arrived in Australia, and whether it arrived with early humans, however that would still mean that they arrived 50,000 years ago, which would definitely make them native in almost any regular description.
The mouse was considered to be stuck on the mainland, which means that if true it would have been lost for good.
Thankfully this was not the case.
This mouse was living under the identity of the Djoongari mouse, or the Shark bay mouse, on an island in shark bay.
Furthermore, by looking at the genetic diversity of these mice (from specimens taken at the time) was high, which makes it clear that right before extinction, there were large numbers of these animals. This means that their extinction was not a natural process as had been assumed, but is instead an issue with human arrival.
Instead, extinct is likely due to a mixture of
While these mice are unlikely to be possible to return to the mainland for some time (until feral cats and other species are eliminated) they can perhaps be introduced to other small islands to guarantee their survival.
The government of the UK has been talking the talk for a significant period of time. At times they have suggested some policies that should move in the right direction, unfortunately they have often reversed these relatively quickly.
An example of this is the governments green housing grants – advertised as intending to improve the UK housing to work more efficiency. Unfortunately, it was cut too soon, had perhaps 1% of the investment needed to get the whole job done, and proved to merely be a handout to building companies.
So what has caught my eye this time?
How is Australia doing?
We need to start reducing emissions at some point – this seems self evident, if we are to meet any of our carbon reduction goals. In Australia the labour and Greens have done a deal that might actually improve policy covering Australia’s biggest polluters.
While the new ideas is complicated, it changes the safeguard mechanism to take the country closer to meeting the goal of cutting greenhouse gas emissions to net zero by 2050.
While Australia’s government has been talking the right talk recently, the Australian newspapers have published fear mongering by the fossil fuel companies – forcing up prices, put domestic gas supply at risk, destroy jobs and “kill foreign investment” in the coal industry, The Daily Telegraph published a story which claimed the changes to the safeguard mechanism would risk $96 billion of energy projects – and that should be seen as “coal hard facts”.
One coal boss told the Australian that the changes to the safeguard mechanism were built on a political objective to push a “base demonisation of fossil fuels” that would threaten Australias role as a “Reliable energy exporter” for the region. This is so completely illiterate of the science as to be laughable (if it was not for the fact that many people will listen).
A former editor of the Australian Chris Mitchel wrote that Environmental journalists and the “left media” were “in a frenzy” over the most recent release from the UNs climate panel – he claimed that they are missing the elephant in the room, that climate change has failed to arrive.
Despite what many in the fossil fuel industry wish to claim, it is not hard to see climate change, indeed it is all around us. Mitchell claimed that the world would not, and could not do without fossil fuels – though if you don’t believe that the climate has been effected, then this is an easier position to reach.
What is clear, is that while the voices against doing what i needed to leave a world we wish to for future generations, have not shut up, in most instances they are not winning.
According to a study on the Thylacine, 1237 observation and claimed sightings have occurred of the Thylacine since it was declared extinct. There are reliable sightings into the 1980s or even later.
The Kiwi is an interesting bird. As with many birds that developed on islands without mammals, they cannot fly.
In the case of new Zealand, the problem is simple. Those migrating to the island, brought with them rabbits. The rabbits escaped, and without any predators increased to silly levels. In order to control the rabbit population, stoats and similar predators were introduced, but these found the Kiwi a far easier meal.
In this instance, 11 birds have been introduced to the wilds near Wellington, for the first time in 100 years. These are the first of 250 birds that will arrive to settle in this area. Being the capital of new Zealand, it is impressive to have any surviving wildlife nearby. Yet Wellington prides itself on this work, and this is not its only move in the direction of rewilding.
It is thought that before humans arrived, as many as 12 million Kiwis roamed free in the country. Currently just 68,000 remain, however this number is growing slowly but surely. The arrival of Kiwi in this area, has required the countries biggest intensive Stoat trapping network as well as buy-in from a disparate array of land users.
This article is a few months old, which is why it is so encouraging that since it was released, the Australian people have risen up, and thrown out the government of Scott Morrison.
Why should he draw so much ire? He worked incredibly hard, while in office to both blame states for not doing the right thing, while at the same time making it as hard as possible. He made comments attacking many of the necessary changes that were going on.

This is because Australia already has a large part of the country unbearably hot. If the temperature increases another 2-5 degrees these areas might well become impossible to survive within.
This is why it is so strange that Australia is so backwards in this respect.
Currently, Australia gets a great deal of money by selling coal abroad. This is because Australia is incredibly rich in coal. As a result they are keen to be able to put off zero carbon as long as possible as they will loose this income.
Professor Lesley Huges is a climate specialist, that has just been appointed to the Australia climate change authority and she has quite rightly stated that 2050 net zero is not good enough. Encouragingly, though she has also said that the new government was showing a willingness to listen to science. The Climate change minister has appointed 3 new members after it was suggested that the authority was to heavily weighted in the direction of business and fossil fuels (if there are too many representatives from this part of the market, then concerns about global warming are likely to get less voice, as fossil fuel companies know they only have a finite length of time to make money from resources that are likely to be banned in the future).
Continue reading “Has Australia actually appointed a climate change authority member who actually wants to do the right thing?”The Platypus was such a wierd looking animal, many of the original scientists that studied specimens sent back to the UK, looked for sewing marks – they believed that it must be several creatures joined together. 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.
New Zealand has no native land mammals. There are mammals that swim to new Zealand, or indeed that fly there, but all the land mammals are non native. Unfortunately with no mammals there are also no predators to control, it is also unfortunately true that in most cases introduced predators take the native flightless birds far more than the non-native mammals.
There are currently thought to be millions of wallabies living free on both of New Zealand. Finally pest control have started to try to deal with these. One pest controller can kill 100 wallabies in a good night. As elsewhere, these wallabies are causing problems, causing local plants to die and get pushed towards extinction.
It is estimated that by 2025 the cost to New Zealand could be costing $84 million a year in damaged ecosystems and lost agricultural revenue.
