Environmental issues

Environmental issues are disruptions in the usual function of ecosystems. Further, these issues can be caused by humans (human impact on the environment) 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.

Environmental protection is the practice of protecting the natural environment on the individual, organizational or governmental levels, for the benefit of both the environment and humans. Environmentalism is a social and environmental movement that addresses environmental issues through advocacy, legislation education, and activism.

Environment destruction caused by humans is a global, ongoing problem. Water pollution also cause problems to marine life. 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. The bulk of environmental impacts are caused by excessive consumption of industrial goods by the world's wealthiest populations. 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.

In response to the unprecedented challenges of climate change, global warming, and environmental degradation, governments and institutions across the world are searching for ways to reduce carbon emissions from the energy, industrial, and transportation sectors. Jhalani Amit et al. explore one crucial area which often escapes adequate attention and i.e. our food system.

Over the past few decades, global meat production and consumption have increased drastically. To meet this growing demand, livestock farming and the meat industry have expanded at an unprecedented scale, resulting in deforestation, excessive water consumption, land degradation, air and water pollution, and significant greenhouse gas emissions. Scientific studies identify the livestock sector as a major contributor to global greenhouse gas emissions. In particular, methane and nitrous oxide, released in large quantities through livestock production, possess a much higher global warming potential than carbon dioxide.
