Environmental issues are disruptions in the usual function of ecosystems.[1] Further, these issues can be caused by humans (human impact on the environment)[2] or they can be natural. These issues are considered serious when the ecosystem cannot recover in the present situation, and catastrophic if the ecosystem is projected to certainly collapse.
Environment destruction caused by humans is a global, ongoing problem.[4] Water pollution also cause problems to marine life.[5] Most scholars think that the project peak global world population of between 9-10 billion people, could live sustainably within the earth's ecosystems if human society worked to live sustainably within planetary boundaries.[6][7][8] The bulk of environmental impacts are caused by excessive consumption of industrial goods by the world's wealthiest populations.[9][10][11] The UN Environmental Program, in its "Making Peace With Nature" Report in 2021, found addressing key planetary crises, like pollution, climate change and biodiversity loss, was achievable if parties work to address the Sustainable Development Goals.[12]
