Ecological crisis in the context of "Theory of evolution"

Human impact on the environment (or anthropogenic environmental impact) refers to changes to biophysical environments and to ecosystems, biodiversity, and natural resources caused directly or indirectly by humans. Modifying the environment to fit the needs of society (as in the built environment) is causing severe effects including global warming, environmental degradation (such as ocean acidification), mass extinction and biodiversity loss, ecological crisis, and ecological collapse. Some human activities that cause damage (either directly or indirectly) to the environment on a global scale include population growth, neoliberal economic policies and rapid economic growth, overconsumption, overexploitation, pollution, and deforestation. Some of the problems, including global warming and biodiversity loss, have been proposed as representing catastrophic risks to the survival of the human species.

The term anthropogenic designates an effect or object resulting from human activity. The term was first used in the technical sense by Russian geologist Alexey Pavlov, and it was first used in English by British ecologist Arthur Tansley in reference to human influences on climax plant communities. The atmospheric scientist Paul Crutzen introduced the term "Anthropocene" in the mid-1970s. The term is sometimes used in the context of pollution produced from human activity since the start of the Agricultural Revolution but also applies broadly to all major human impacts on the environment. Many of the actions taken by humans that contribute to a heated environment stem from the burning of fossil fuel from a variety of sources, such as electricity, cars, planes, space heating, manufacturing, or the destruction of forests.

Daniel Goleman (born March 7, 1946) is an American psychologist, author, and science journalist. For twelve years, he wrote for The New York Times, reporting on the brain and behavioral sciences. His 1995 book Emotional Intelligence was on The New York Times Best Seller list for a year and a half, a bestseller in many countries, and is in print worldwide in 40 languages. Apart from his books on emotional intelligence, Goleman has written books on topics including self-deception, creativity, transparency, meditation, social and emotional learning, ecoliteracy and the ecological crisis, and the Dalai Lama's vision for the future.

Degrowth is an academic and social movement aimed at the planned and democratic reduction of production and consumption as a solution to social-ecological crises. Commonly cited policy goals of degrowth include reducing the environmental impact of human activities, redistributing income and wealth within and between countries, and encouraging a shift from materialistic values to a convivial and participatory society. According to degrowth theorists, degrowth is a multi-layered concept that combines critiques of capitalism, colonialism, patriarchy, productivism, and utilitarianism, while envisioning more caring, just, convivial, happy, and democratic societies.

Degrowth is critical of the concept of growth in gross domestic product as a measure of human and economic development. It argues that modern capitalism's unitary focus on growth causes widespread ecological damage and is unnecessary for the further increase of human living standards.

The 2020s (pronounced "twenty-twenties" or "two thousand [and] twenties"; shortened to "the '20s" and also known as "The Twenties") is the current decade that began on 1 January 2020, and will end on 31 December 2029.

During the early part of this decade, the world population grew from 7.7 billion to over 8 billion people. In 2023, India overtook China to become the most populous country in the world. The COVID-19 pandemic and its aftermath marked the early 2020s. The first reports of the virus were published on 31 December 2019, though the first cases are said to have appeared nearly a month earlier. The pandemic led to a global economic recession, sustained rise in global inflation, and supply chain crisis. The World Health Organization declared the virus a global state of emergency. With multiple extreme weather events and ecological crises continuing to escalate, several world leaders have called the 2020s the "decisive decade" for climate action. The years 2023 and 2024 both broke yearly global temperature records, with 2024 breaching 1.5 °C above pre-industrial levels.

Religion and environmentalism is an emerging interdisciplinary subfield in the academic disciplines of religious studies, religious ethics, the sociology of religion, and theology amongst others, with environmentalism and ecological principles as a primary focus.

Within the context of Christianity, in the encyclical "Laudato si'", Pope Francis called to fight climate change and ecological degradation as a whole. He claimed that humanity is facing a severe ecological crisis and blamed consumerism and irresponsible development. The encyclical is addressed to "every person living on this planet."

Iran is one of the world's largest and most densely populated countries, spanning an area of approximately 1.7 million sq. km and a population of 91.5 million. Since 1966 Iran has experienced immense population growth, initially being recorded at 25,781,090 people, and totaling to 75,330,000 in 2010. The various climates, increased population growth, heavy reliance on fossil fuels, and refusal to commit to sustainability goals has extenuated Iran's vulnerability to ecological crisis and climate change.

Environmental issues in Iran include, especially in urban areas, vehicle emissions, refinery operations, and industrial effluents which contribute to poor air quality. A report by the United Nations Environment Programme ranked Iran at 117th place among 133 countries in terms of environmental indexes. Water scarcity is also a concern since the increased temperatures and fluctuating precipitation levels associated with global warming can result in droughts or flooding that will further degrade the water availability.
