Beijing and Shenzhen's rapid urbanization:
Deforestation in Brazil:
> Changing rainfall patterns, climate variability, high levels of evaporation, reduced snow melt runoff, and current water use patterns are putting pressure on water management resources at Lake Mead as the population relying on it for water, and the Hoover Dam for electricity, continues to increase. To lower the minimum lake level necessary to generate electricity from 1,050 feet (320 m) to 950 feet (290 m), Hoover Dam was retrofitted with wide-head turbines, designed to work efficiently with less flow in 2015 and 2016. If water levels continue to drop, Hoover Dam would cease generating electricity when the water level falls below 950 feet (290 m) and the lake would stabilize at a level of 895 feet (273 m) when the water reaches the lowest water outlet of the dam. In order to ensure that the city of Las Vegas will continue to be able to draw its drinking water from Lake Mead, nearly $1.5 billion was spent on building a new water intake tunnel in the middle of the lake at the elevation of 860 feet (260 m). The 3-mile (4.8 km) tunnel took seven years to build under the lake and was put into operation in late 2015.
Up stream releases 10,150,000 ML per year, Vegas recently upgraded the capacity to consume up to 1,244,000 ML per year.
As per usual the capacity of natural systems is much higher than the first order effects from people.
It's only when we look at second and third order effects or cumulative effects that we start to see real anthropocentric effects

The Chinese one on the other hand, isn't so useful for any of that. All the lines are the same thickness, and there are no smaller features for fine calibration or measurements. For just calibration, it's far bigger and more complex than necessary.
What an effective use of technology, thank you EarthEngine team.
Youtube contributed to the rise of authoritarians like Trump and Bolsonaro who scoff at environmentalists.
Youtube merrily signal-boosted anti-environmentalist conspiracy theories.
What a fantastic world we could have, through new technology. What a mess we actually have, partly because of leadership failures at Google and the half-dozen usual suspects.

For one thing, "reason" alone is not good enough: one also needs access to correct facts. The day isn't long enough to gather accurate information when the internet is drowning in garbage... and, as they say, GIGO. I personally wish I knew enough about medicine to reason about COVID19. I do not, and should I devote the time, it would be at the expense of some other area (GPT-3? The Roman Empire?)
For another, plenty of propaganda is soundly reasoned, in one context, and yet damaging to the public at large. Inter-group animosity, for example, can certainly provide sound reasons for one group in society to hate another. There is seldom a clearly "correct" answer to "with whom should I identify the most?"
For example, in the context of environmentalism, a group could justly argue "if you're over 50, environmentalist groups will harm your life, more than help." Whether that makes sense depends entirely on whether you choose to care about what happens to other people, after you die. That it is a sound argument, does not make it an argument that benefits humanity, as a whole.
Google hasn't been serious about its effects on the world. As enjoyable as Youtube can be, it has also done great harm.
They’re conspiracy theorists. I’m not.
I am not alone in this situation.
I find that hard to believe.
Well, Mars. Obviously. /s
It's not about us. It's about the planet. Climate change only threatens us as a species. Once we're gone, the planet will recover. It's recovered from eco-collapse before, and it will do it again.
COVID-19 is just a way of the Big Pharma to fill their pockets and for politicians to make a power grab (never waste a good crisis)
Spoiler: you cannot. If humans were to set their purpose to kill the planet, they would kill themselves at best, and I am not even so sure of that.
It is worth to take a closer look. Here you can see how the Highway (Autobahn A44) is spared at the beginning until it is destroyed around 2006. It was reconstructed and reopened in 2018. It is frightening to see how the villages get eaten by the mine. At the same time you can also see the construction of the relocated villages Otzenrath, Holz and Spenrath north of the mine.
Our commitment to pulling stuff out of the ground and burning it, in the face of all the science, is impressive.
Had we not started cooking our food over open fires, incurring significant damage to our health in the process, our societal and technological progress would also have been retarded.
However, that's not a sufficient or satisfactory answer to the question 'Should we still be doing this?'
The datasets you pick from can be a bit confusing unless you click the (!) icon next to the names to figure out what they are.
I'll provide an example for looking at reconnaissance satellite images of Atlanta, Georgia in 1979.
Search Criteria (tab):
Find Atlanta, Georgia on map. Zoom in on Atlanta, Georgia. Click on a building like the "Fulton County Courthouse" or "Atlanta City Hall" (does not really matter, but somewhere near them).
Date Range: 01/01/1970 - 01/01/1980
Data Sets (tab):
Declassified Data -> [check] Declass 3 (2013)
Click one of the results.

The mines are abandoned now
Edit: updated link - zoom out, a lot of kentucky is affected by this.
It was already impressive in 1984. Also interesting is the slow migration of sand banks on the Haringvilet estuary.
This is not remotely what is suggested by numerous studies. You can see in Africa for example deforestation and regrowth (in other areas) as whole make a balanced picture of tree biomass:
Of course there are countries like Brazil where deforestation is happening at a faster pace (mainly driven by poverty and poor agricultural efficiency in the Amazon), but that does not mean the whole world is following the same trend. That's alarmism.
The problem is that we’ve dramatically accelerated the movement of flora and fauna around the world, and ecosystems can’t keep up with those changes (among many others we’ve caused).
You will need to have some sources to back that claim.
Is that what I said? My point is that if you only show the areas where deforestation happens you are missing the picture where trees are growing. That's called negative bias.
