Environment destruction caused by humans is a global, ongoing problem. [4] Water pollution also cause problems to marine life. [5] Some scholars believe that the projected peak global population of roughly 9-10 billion people could live sustainably within the earth's ecosystems if humans worked to live sustainably within planetary boundaries.
Urbanization causes overcrowding and increasingly unsanitary living conditions, especially in developing countries, which in turn exposes an increasingly number of people to disease. About 79% of the world's population is in developing countries, which lack access to sanitary water and sewer systems, giving rises to disease and deaths from ...
They are loosely divided into causes, effects and mitigation, noting that effects are interconnected and can cause new effects. Issues ...
This form of pollution can lead to many problems. One is the degradation of aquatic ecosystems. Another is spreading water-borne diseases when people use polluted water for drinking or irrigation. [3] Water pollution also reduces the ecosystem services such as drinking water provided by the water resource.
[22] [23] Further problem areas are air and water pollution (including nutrient pollution), over-exploitation, invasive species [24] and climate change. [ 21 ] Many scientists, along with the Global Assessment Report on Biodiversity and Ecosystem Services , say that the main reason for biodiversity loss is a growing human population because ...

The scientific community has been investigating the causes of climate change for decades. After thousands of studies, the scientific consensus is that it is "unequivocal that human influence has warmed the atmosphere, ocean and land since pre-industrial times."
In Hardin's essay, he proposed that the solution to the problem of overpopulation must be based on "mutual coercion, mutually agreed upon" and result in "relinquishing the freedom to breed". Hardin discussed this topic further in a 1979 book, Managing the Commons, co-written with John A. Baden.
