&lt4. Farmland species diversity is damaged
In addition to the accelerated loss of the diversity of major crops and their cultivars, the biodiversity of animals, plants, microorganisms, etc., which are closely related to agriculture, with farmland or soil environment as the core, has also been damaged. Many beneficial animals, marsh wet or aquatic plants, The species or population structure of insects, natural enemies of pests, fungi, bacteria, etc. have undergone significant changes, and their numbers have decreased significantly or disappear forever. The number of pest species and populations has increased sharply, and the abundance of farmland biodiversity has declined significantly. The United Nations report pointed out that in recent years, bee populations, which are closely related to crop pollination and yield, are dying out at an alarming rate, especially in the northern hemisphere. In the past 20 years, the number of bees in the United States and Europe has decreased by 30% and 10%-30%, respectively, while the size of bee populations in the Middle East has shrunk by more than 85%.

In China, many studies and a large number of empirical evidence have shown that the population of beneficial organisms or natural enemies of pests represented by birds, snakes, insects, earthworms, nematodes and ants is rapidly shrinking, while rodents are typical pests. The population density has soared, and some major agricultural and forestry diseases and pests have continued to increase, and the damage has increased. The types or numbers of aquatic animals, insects, frogs, earthworms, algae, weeds, and soil organisms in the southern rice field ecosystem have decreased significantly, and diversity has gradually been lost.

&lt5. The invasion of alien organisms is raging
With the continuous deepening of global economic integration and the intensification of climate change, in recent years, the degree of damage from alien biological invasions worldwide has increased day by day, and more than 100 species of alien invasive organisms are recognized internationally as the most threatening. At present, there are 544 species of alien organisms invading China, of which 100 are more severely harmful, and more than 50 are internationally recognized as the most threatening invasive species.

The agricultural crisis: excellent work
(TL note. excellent work ~ good practice)
Trying to explore the main inducing factors of the agricultural biodiversity crisis:　　

&lt1. lagging in thinking and understanding
One is the weak sense of crisis. For a long time, due to the limitations of understanding of nature and the objective world, the appearance of abundance of natural resources, and the deviation or misleading of public opinion, humans, especially Chinese, and even governments and management departments at all levels have a blind sense of superiority. , Resources and environmental concerns and sense of crisis are seriously lacking, and further foreshadowed the destruction of biodiversity and ecological environment.

Second, the development concept is lagging behind. Long-term poverty and backwardness, material deprivation, and stagnant economic development have made the Chinese people excessively strong desire to get rid of poverty and become prosperous. Utilitarianism is so prevalent, the color is so strong that it is too short-sighted, and one-sided pursuit of economic aggregate scale and growth rate or unrealistic "leapfrog." Development, while ignoring the inherent quality and efficiency of development and resources and environmental costs.

At the same time, misunderstanding the true meaning of development, simply equating "development" with growth, and blindly focusing on immediate benefits, temporary benefits, partial benefits and short-term benefits, which are scientific, harmonious, balanced, inclusive, and sustainable for development. The overall coordination and balance of sex and "people-oriented" lack sufficient understanding.

The third is superficial understanding. Based on objective reasons such as the gradual, concealed, long-term and complex nature of the loss of biodiversity, many managers, especially farmers, and even scientific and technical personnel have not yet truly fully understood and grasped the importance of biodiversity in resource and environmental protection. And the important position, role and far-reaching significance in the construction of ecological civilization.

Or still stay at the initial level of “pollution control” and “forest protection”, lacking basic knowledge or little understanding of the concept, connotation, and importance of deeper biological diversiPost too long. Click here to view the full text.

&lt3. Extensive agricultural and rural production and management
One is the lagging development concept. Throughout the ages, from foreign to domestic, scientific research to production, obtaining the highest or higher agricultural output has always been the primary goal and even the ultimate goal of people's diligent pursuit. However, excessive, blind or one-sided pursuit of temporary yield indicators, immediate benefits, or short-term efficiency and efficiency has prompted people to rush to make manual selection and "survival of the fittest" from the start of the cultivation of new agricultural varieties, leading to the intensification of production links. Professional and large-scale operation and management. Large-scale simplification has continuously promoted the cultivation of high-yield "good" varieties and "unscrupulous" supplemented by all comprehensive measures for breeding and cultivation that capture high yields, ensure a bumper harvest and increase benefits, while ignoring the protection of germplasm resources and genetic diversity, and despising the ecological environment and The protection of industrial diversity ignores the long-term, continuity and scientific nature of production increase, growth or development.

The second is the predatory development of agricultural natural resources. Based on the deviation of development concept and the limitation of understanding, the desire to pursue output value, increase income and efficiency, and get rid of poverty and get rich is too strong, and the objective reality of the belief of "relying on mountains to eat mountains, relying on water to draft water" has led to the destruction of forests and reclamation of wasteland from the sea (lake). (Land), blindly introducing species and disorderly development of wildlife resources, and other chaotic phenomena, such phenomena as indiscriminate logging, indiscriminate cultivation, indiscriminate grazing, indiscriminate harvesting, and indiscriminate introduction have been repeatedly prohibited. At the same time, rural construction is disorderly and out of standard, land utilization rate is seriously low, lack of planning, scattered layout, blind comparison, greed for foreign, over-occupation of cultivated land and extravagant waste and other undesirable tendencies coexist, resulting in a negative impact on agricultural resources, environment andPost too long.

&lt5. Climate change and natural disasters
At present, global climate change is becoming more and more intense, natural disasters are frequent, and the impact is becoming more extensive and far-reaching. The continuous warming of climate and the dramatic changes in rainfall in time and space, on the one hand, can directly change the survival and development of agricultural organisms and the geographical distribution range, intensify the process of coastal soil salinization and swamping, and cause the shrinkage of agricultural habitats. On the other hand, it destroys the original agricultural ecosystem and agricultural biodiversity. Extremely severe droughts, rapid droughts and floods, rare storms (snow), sandstorms, low temperatures and freezing, high temperatures and heat, mudslides, etc., dominated by extreme abnormal weather and natural disasters are frequent and frequent, which has caused and is bringing direct damage to the agricultural ecological environment Or destroy, exacerbate the agricultural biodiversity crisis.

Conclusion: Crisis
In summary, China’s agricultural biodiversity crisis has quietly arrived and is becoming increasingly severe. Its causes are complex and multifaceted. It is not only closely related to direct, subjective, and controllable human factors, but also has objective and irresistible natural forces. Comprehensive role. But in the final analysis, human activities or man-made damage are the most fundamental reasons that lead to and aggravate the loss or crisis of agricultural biodiversity. It is the inevitable result of people's long-term deviation from objective natural laws, eagerness for quick success, and blind development. At the same time, the process of biodiversity loss is gradual, continuous, hidden, complex and irreversible, and its impact is extensive, profound, serious and lasting. Therefore, it is urgent to examine, understand, and protect agricultural biodiversity with a global vision, an international background, and the sustainable development of human society; only to fully respect nature, conform to nature, and respect nature, and completely transform the old, backward and unconventional. The rational traditional development concept and the extensive and inefficient development model, and the establishment and consistency of the scientific and sustainable "five major" new development concepts can effectively guarantee the agricultural biodiversity and ecological environment safety, as well as the harmony and co-prosperity of man and nature.

I was just about to inquire with some Germanons about how reliable those Heske papers are. Eye-opening if so - makes one wonder where Wikipedia's 1989 estimates of $9.7k and $5.1k (on the same page!!!) are pulled from.

Correct me if I missed something, comrades.

>>3011
You missed the part about the banking hegemony where countries are invaded when they stop using the dominant financial transaction system. You know like in Libya the first thing the counter revolutionaries did was create a new central bank to undo the Gold-dinar that Gaddafi had implemented. I think this is a relatively recent development of imperialism.

>>3012
Monopolies became entrenched around the late 1800s before the formation of our modern credit system. A credit system which Lenin nor Marx could not commentate on as the the gold standard had not been dropped in place of the US dollar yet. Libya's threat to the US dollar would lower the demand for the US dollar and weaken its purchasing power. The US has a trade deficit, thus its dollars flood foreign markets, particularly those which it extracts value from. Its military opens up new markets and creates more capital in the process of capital accumulation.
Michael Hudson explains this much better than I can, and he is foremost the leading economist in formulation of American imperialism and the debt economy.

microeconomics is basically pseudoscience on the same tier as Jungian psychoanalysis. it’s all just speculation without any falsifiability. I don’t think it’s intentional, just that lolberts and neolibs are too divorced from reality to see it.

>>2543
I understand that as the majority of microeconomics, and economics as a whole, is divorced from political economy. Microeconomics particularly ignores any repucussions to society; instead focusing on a framework of atomised firms. Ideology is left to fill in gaps. Particularly, the emhasis on exchange value ("commodity fetishism") which I would argue the majority of macroeconomics seems to make the mistake as well. The gravitas of value is simply underestimated at best.

Micro/macro split has been shrinking in relevance since the Lucas critique. It isn't really a thing anymore.

They're different lenses suited for different problems but micro still acknowledges the wider society and macro still acknowledges the individual. The perspectives aren't at odds.

If you are German I can just send you my analysis script. Teaches you everything you need to know about higher level mathematics.

Introduction to Electrodynamics by David Griffiths might be what you’re looking for. it goes over the math you need for the book and it teaches you all about electricity and magnetism which are very easy to experiment with by just picking up a breadboard and some wires and batteries.

What kind of things do you do? As someone with a maths degree it isn't all that practical. The most useful is probably trigonometry and just knowing algebra well, so you can rearrange equations to find out stuff.

Doesn't copper oxidize, effectively having to be replaced every 10-20 years because it's surface wouldn't inactivate viruses anymore?

>>3614
i wonder if you could just sand/scruff the surface??

>>3614
No, read the piece
>Another reason copper may have been passed over for steel, plastic, or glass is that it can easily tarnish and requires a lot of cleaning to remain shiny. “But copper is antimicrobial regardless of how grody it looks, if it turns green on you, it still has the ability to kill bacteria and viruses and fungi,” he said.

Whales are one of the best ways to sustainably store carbon away from the environment because they eat a lot and then sink to the bottom of the ocean.

Why are whales going extinct? Over-fishing, pollution, lots of reasons

>Now we turn to the economic side of the solution. Protecting whales has a cost. Mitigating the many threats to whales involves compensating those causing the threats, a group that includes countries, businesses, and individuals. Ensuring that this approach is practical involves determining whales’ monetary value.

I've never ordered directly from Verso, but yeah, their books are shit quality. Not only paper-wise. Some are OCRed from other publisher's editions that were sold out, with absolutely no quality checks. So you get wrong letters and missing punctuation.
This level of sloppiness for such a publisher is simply incomprehensible to me. If I knew it'd be this bad I'd rather get a torned up used copy of the other publisher's sold out edition for a heavily inflated price.
Fuck Verso. Never again.

Marxists acknowledge that contradictions are inherent to all things in themselves across all times. There is no such thing as an absolute harmony which can be disturbed or reach. Hence dialectics are anti-determinist at a fundamental zero-level.

Historical determinism is often used to mean the belief that history is outside the control of humanity and instead happens to them like the weather.

Meanwhile Marx claimed that humans are capable of consciously changing their material conditions (by "revolutionary activity").
