Before Europeans arrived, Grizzly bears were relatively common in California, with an estimated population of 10,000, around 20% of the USA population at the time.

The car industry has done a great job over the last roughly 30 years, of confusing people. It was once the case, that there were 2 different states – the first cars were electric (so suggesting that modern electric cars are a new technology is ridiculous) and then we developed internal combustion engine vehicles. This meant that there were 2 different types of propulsion 1. fossil fuels (petrol, diesel) or 2. electric cars, charged from the mains.
Toyota developed the Prius back in 1997. At the time, a huge step forwards – it only had a battery of 1.3kwh, but this was enough to store energy recovered from braking and release it back, when the car was able to start moving again. This was the first mild hybrid as it is now called.

Who are these so called experts? What is there expertise in, and do other experts agree? Their expertise does not appear to have much backing it.
This engine weighs just under 11kg, and they believe that, as it delivers better efficiency and emission control, all within a sleek design. In the literature, so much is made of the efficiency of this engine, but that misses the point. They suggest that this efficiency closes the gap between combustion engines and electric ones.
This misses the point: electric cars are zero carbon at use. Therefore, the cleaner the grid gets, the lower the carbon will be. As such, it is all very well to compare electric cars now, to an experimental engine that will be in cars in a generation or two. However, in 2 generations, it is thought that most countries will have further greened their grid, leaving the electric car still ahead.
We drive an electric car, and as we pay our electricity company for 100% clean electricity, our carbon emissions are essentially zero (particularly, as we bought the car second hand). One could, quite rightly, argue that not all the electricity that we use comes from zero carbon electricity – instead, we use whatever electricity is being created at the time. But that is the point- our supplier buys enough zero carbon electricity to cover all our use, therefore, if they were supplying everyone in the country a 100% zero carbon electricity, they would have to buy enough green electricity for everyone. That could only be done by all the electricity in the country being green.
So, in short – suggesting an uber efficient small ICE engine used 10-20 years in the future is more efficient than an electric car driven on the grid now, is not a fair comparison. It is like comparing the price of apples now, to the price of futures in oranges next year. Do not buy into it. If every person in the UK drove an electric car, carbon emissions would be far lower, than if everyone drove the most efficient ICE car that has, or ever will be made (this seems pretty obvious, do not get hoodwinked).

Why are people determined to believe that wind turbines kill whales
Coastal Australia is having another flare-up where locals are suggesting that wind turbines are killing whales. If this were the case, it would mean that those who want to save the planet would need to choose between climate change and conservation of whales.
Read more: Why are people determined to believe that wind turbines kill whalesPictures put up, include images of whales on fire, among others – paid for Newcastle adn Port Stephens Game Fish Club. They suggested that the posters highlighted risks that were known for the whales, but there is no credible evidence that wind turbines have any impact on whales (except during building, but as the picture shows this is short-lived). Indeed Quentin Hanich who is the editor of the academic journal Marine Policy recently had to spend a week debunking a fake article that purported to come from his publication, which claimed that 400 whales would die a year, if a proposed wind farm went ahead. While the facebook post where it originated was taken down, the fake articles can be written far faster than they can be taken down. This offshore wind farm in New south Wales, is opposed by everyone from locals to MPs from outside the region – usually because the are opposed to renewable energy development.
This seems short-sighted- while Australia does have a large coal industry, most is exported (only around 30% is used in the country, and coal in electricity generation is now so much more expensive than almost any renewable generation, that its days are numbered) and of Japan,South Korea, Taiwan,and India which takes the majority, only India does not have a 2050 pledge of zero carbon – so if those promises are to be kept, the market for most of the coal will disappear within the next 25 years.
Opposition has been fanned by the coalition, and people like Baraby Joyce (a renewable energy opponent and climate change denier) have been loudly stating that support for renewables was a cult and the people should fight back.
Amanda De Lore is also fighting against it, and suggest that the 3 month consultation period was rushed and hidden (it was not) and that offshore wind is “not clean, green energy”. She stated that the project was not taking her groups concerns into consideration. However, when concerns are raised which do not conform with reality (like suggesting that offshore wind turbines are not green) they should be ignored. Importantly, when you compare the death toll of offshore wind turbines to a coal power plant, the numbers are stark with thousands more species killed by coal power.
This is part of the issue with public consultation. When opponents lace the population with falsehoods, you find yourself having to engage in a years-long effort to correct, before you can even have an intelligent conversation.
Extreme heat is killing many Amazonian Dolphins
As the temperature rises in the Amazon, Amazonian dolphins are struggling to survive. Several hundred have died in and around lake Tefe where the temperature has reached 39 degrees Celsius – for reference, a hot bath is anything above 37 degrees (at 44 degrees, people start to scald).
Their bodies along with many thousands of fish, are floating on the surface. The lake is particularly hot, as a drought has led to much of the water drying up, allowing the remaining water to take the temperature of the air more quickly. While disease and sewage contamination are being checked, the hugely high temperature has a huge impact on the bodies of everything living in the water, so even if the eventual death is caused by something else, the heat would likely have killed the dolphins in the near future anyway.
Brazil is not the only country which is struggling in this way, it is happening world wide. It is true that the world has just left the El nino period, which always has higher temperatures, but still, many species like the Amazon dolphins (which is already endangered) cannot face this pressure for long, without being pushed far closer to extinction.
Sweden began its annual wolf hunt on the first day of the year
I have talked about about wolf hunts in Sweden in the past. They recently reduced the required minimum population from 300 wolves down to 170 – given that the 300 was worked out scientifically (and most people believe that this population is way too small anyway).
The current population is 374, with a target kill this year of 30. The intention is to kill 5 families. However, this number of wolves is certainly not good. Sweden is a country of similar size to France, and much of the country is wild so a far larger population would be capable of not impacting humans.
Campaigners are claiming that this is illegal (and it is hard to argue them) as the Berne convention states that protected species cannot be caused to have their population fall below sustainable numbers – 170 is well below this level, and indeed 300 is likely only healthy long-term, because of wolves crossing over the border from Russia.
I have been lucky enough to see 2 Swedish wolves, one from a bear hide, and the other while watching a group of Elk. Well structured, the wolves in Sweden could be a huge positive for the country, particularly tourism and one would think would be important as Sweden has positioned itself as an ecotourism hotspot.
Without a change, they will destroy this early market which is good for the country.

Wildcat kittens born outside captivity in Cairngorms
Wildcats are native to the UK, but have been pushed to the brink of extinction by hybridisation with native cats – which come from the wildcats from places like Israel in the middle east. As a result of this, as well as trying to remove the feral domestic cats, and their descendants, they are trying to create pockets of Scotland, which would allow these cats to recover.
The natural behaviour of a British wildcat when meeting a feral cat, is to kill it. However, as these animals become rarer, even rare breeding events, can threaten the survival of the whole species. This behaviour also means that with careful planning, we should be able to reintroduce them into other parts of the country. There are a range of other wild predators lost over the last couple of millennia – and I hope to see the others return, but it is thrilling to know that a wildcat is once again living and breeding in its native habitat of the Scottish mountains.
These wildcats are thought to be the first born wild in Scotland for 5 years, after 19 wildcats bred in the Highland wildlife park, were released into the Cairngorms national park.
Black rhino calf born in Kenya
The eastern black rhino is incredibly endangered, with just 1000 spread across a huge area. In this region, just 8 are known to live, so to see young is incredibly rare.
Rhino horn is incredibly valuable on the far East traditional medicine market, despite the fact that multiple scientific studies have shown that the rhino horn does nothing for humans. Never-the-less, this unmet demand for rhino horn, linked with the huge explosion of wealth in places like China, means that rhino horn is incredible valuable. While eastern black rhino horns rarely weigh more than 3kg, this can still be worth $200,000, which is very tempting, in a country where the average salary is under $200 a month.
As living conditions increase in the area, the desire to poach these animals is likely to decrease. Of course, these rhino are also likely to be worth similar amounts in tourism dollars across their lifetime, but that is a long-term thing, and something that the whole area benefits from (rather than the poacher, who is often struggling to make ends meet – though middlemen are instead making a fortune).
