Large amounts of data have been gathered and these are collated into reports, of which a common type is the State of the Environment publications. A recent major report was the Millennium Ecosystem Assessment , with input from 1200 scientists and released in 2005, which showed the high level of impact that humans are having on ecosystem services . The only question is whether will become resolved in pleasant ways of our own choice, or in unpleasant ways not of our choice, such as warfare, genocide, starvation, disease epidemics, and collapses of societies.
In 2006, many species were formally classified as rare or endangered or threatened ; moreover, scientists have estimated that millions more species are at risk which have not been formally recognized. About 40 percent of the 40,177 species assessed using the IUCN Red List criteria are now listed as threatened with extinction —a total of 16,119. Sustainability is the key to prevent or reduce the effect of environmental issues. There is now clear scientific evidence that humanity is living unsustainably, and that an unprecedented collective effort is needed to return human use of natural resources to within sustainable limits. For humans to live sustainably, the Earth's natural resources must be used at a rate at which they can be replenished . This condition is measured by ecological footprint accounting. There are an increasing number of films being produced on environmental issues, especially on climate change and global warming . Al Gore's 2006 film An Inconvenient Truth gained commercial success and a high media profile. Environmental issues are harmful effects of human activity on the biophysical environment . Environmental protection is a practice of protecting the natural environment on the individual, organizational or governmental levels, for the benefit of both the environment and humans. Environmentalism , a social and environmental movement , addresses environmental issues through advocacy, education and activism. The level of understanding of Earth has increased markedly in recent times through science , especially with the application of the scientific method . Environmental science is now a multi-disciplinary academic study taught and researched at many universities. Many other scientific disciples, including ecology , toxicology , forest science , fisheries science , etc. are necessary for obtaining full scientific understanding. Credible, comprehensive, and readily accessible scientific knowledge is essential for addressing environmental issues. what are the different environmental issues in the The carbon dioxide equivalent of greenhouse gases in the atmosphere has already exceeded 400 parts per million . The amount of greenhouse gas in the atmosphere is possibly above the threshold that can potentially cause climate change. The UN Office for the Coordination of Humanitarian Affairs has stated "Climate change is not just a distant future threat. It is the main driver behind rising humanitarian needs and we are seeing its impact. The number of people affected and the damages inflicted by extreme weather has been unprecedented." Further, OCHA has stated: Environmental issues are addressed at a regional, national or international level by government organizations. Major current environmental issues may include climate change , pollution , environmental degradation , and resource depletion . The conservation movement lobbies for protection of endangered species and protection of any ecologically valuable natural areas , genetically modified foods and global warming . The largest international agency, set up in 1972, is the United Nations Environment Programme . The International Union for Conservation of Nature brings together 83 states, 108 government agencies, 766 Non-governmental organizations and 81 international organizations and about 10,000 experts, scientists from countries around the world. International non-governmental organizations include Greenpeace , Friends of the Earth and World Wide Fund for Nature . Governments enact environmental policy and enforce environmental law and this is done to differing degrees around the world. Concerns for the environment have prompted the formation of green parties , political parties that seek to address environmental issues. Initially, these were formed in Australia, New Zealand, and Germany but are now present in many other countries. Environmental issues what are the different environmental issues in the

Environment destruction caused by humans is a global, ongoing problem. By the year 2050, the global human population is expected to grow by 2 billion people, thereby reaching a level of 9.6 billion people. The human effects on Earth can be seen in many different ways. A main effect, is an increase in global temperature. According to the report ”Our Changing Climate”, the global warming that has been going on for the past 50 years is primarily due to human activities. Since 1895, the average temperature in the United States has increased by between 0. what will be the top 10 environmental issues by 20 7
