Arthur T Knackerbracket has found the following story:

Global emissions of methane have reached the highest levels on record. Increases are being driven primarily by growth of emissions from coal mining, oil and natural gas production, cattle and sheep ranching, and landfills.

Between 2000 and 2017, levels of the potent greenhouse gas barreled up toward pathways that climate models suggest will lead to 3-4 degrees Celsius of warming before the end of this century. This is a dangerous temperature threshold at which scientists warn that natural disasters, including wildfires, droughts and floods, and social disruptions such as famines and mass migrations become almost commonplace. The findings are outlined in two papers published July 14 in Earth System Science Data and Environmental Research Letters by researchers with the Global Carbon Project, an initiative led by Stanford University scientist Rob Jackson.

In 2017, the last year when complete global methane data are available, Earth's atmosphere absorbed nearly 600 million tons of the colorless, odorless gas that is 28 times more powerful than carbon dioxide at trapping heat over a 100-year span. More than half of all methane emissions now come from human activities. Annual methane emissions are up 9 percent, or 50 million tons per year, from the early 2000s, when methane concentrations in the atmosphere were relatively stable.

In terms of warming potential, adding this much extra methane to the atmosphere since 2000 is akin to putting 350 million more cars on the world's roads or doubling the total emissions of Germany or France. "We still haven't turned the corner on methane," said Jackson, a professor of Earth system science in Stanford's School of Earth, Energy & Environmental Sciences (Stanford Earth).

[...] According to Jackson and colleagues, curbing methane emissions will require reducing fossil fuel use and controlling fugitive emissions such as leaks from pipelines and wells, as well as changes to the way we feed cattle, grow rice and eat. "We'll need to eat less meat and reduce emissions associated with cattle and rice farming," Jackson said, "and replace oil and natural gas in our cars and homes."

    humans capitalists.
    Most other institutions were at least an order of magnitude less efficient at killing the nature.

    No, humans. Capitalism is natural and has existed from the dawn of time. Exchange of money or capital for other capital is capitalism.

    China was nothing but a big poor poverty filled country before they adopted capitalism in the 1980's and in 40 years have become rivals of the US. Second biggest economy in the world now. High speed rail second to none. Huge financial centers. Manufacturer of all of the worlds products. All a result of capitalism

    The Soviet Union self-destructed under communism in the late 1980's. They couldn't compete with the US and their socialist economy collapsed. Russia and other eastern European countries adopted capitalism and lifted their countries up from the brink of economic collapse.

    Is even one example of a successful non-capitalistic country?

    If you are even thinking that communism somehow magically immune from pollution or ecological destruction, then you need to spend some time reading about the environmental atrocities committed by the Soviet Union, China, Cuba during their hey-day! Look up the Aral Sea for instance.
