Our environment is constantly changing.
There is no denying that. However, as our environment changes, so does the need to become increasingly aware of the problems that surround it. With a massive influx of natural disasters, warming and cooling periods, different types of weather patterns and much more, people need to be aware of what types of environmental problems our planet is facing. Global warming has become an undisputed fact about our current livelihoods; our planet is warming up and we are definitely part of the problem. However, this isn’t the only environmental problem that we should be concerned about.
Our planet is poised at the brink of a severe environmental crisis. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14: Public Health Issues: The current environmental problems pose a lot of risk to health of humans, and animals. 15. Environmental issue. Environmental issues are harmful effects of human activitity on the biophysical environment.
Environmentalism, a social and environmental movement, addresses environmental issues through advocacy, education and activism. The carbon dioxide equivalent of greenhouse gases (GHG) in the atmosphere has already exceeded 400 parts per million (NOAA) (with total "long-term" GHG exceeding 455 parts per million).
(Intergovernmental Panel on Climate Change Report) This level is considered a tipping point. Mount Everest. Everest from space Mount Everest (also known in Nepal as Sagarmatha and in Tibet as Chomolungma) is the Earth's highest mountain.
It is located in the Mahalangur section of the Himalayas. Its peak is 8,848 metres (29,029 ft) above sea level and is the 5th furthest point from the centre of the Earth. The international border between China and Nepal runs across the precise summit point. Its massif includes neighboring peaks Lhotse, 8,516 m (27,940 ft); Nuptse, 7,855 m (25,771 ft) and Changtse, 7,580 m (24,870 ft). Environmental disaster. Image of the surface of waste found inside double-shell tank 101-SY at the Hanford Site, April 1989 An environmental disaster is a disaster to the natural environment due to human activity, which distinguishes it from the concept of a natural disaster.
It is also distinct from intentional acts of war such as nuclear bombings. Environmental issues in Australia. Environmental issues in Australia describes a number of environmental issues which affect the environment of Australia.
There are a range of such issues, some of them relating to conservation in Australia while others, for example the deteriorating state of Murray-Darling Basin, have a direct and serious effect on human land use and the economy. Many human activities including the use of natural resources have a direct impact on the Australian environment. These issues are the primary concern of the environmental movement in Australia. Climate change Water pollution. Water pollution is the contamination of water bodies (e.g. lakes, rivers, oceans, aquifers and groundwater).
Water pollution occurs when pollutants are directly or indirectly discharged into water bodies without adequate treatment to remove harmful compounds. Water pollution affects plants and organisms living in these bodies of water. In almost all cases the effect is damaging not only to individual species and populations, but also to the natural biological communities. Introduction Water pollution is a major global problem which requires ongoing evaluation and revision of water resource policy at all levels (international down to individual aquifers and wells).

Click for more detail Thermohaline Change Evidence is growing that the thermohaline current may be slowed or stopped by cold fresh water inputs to the Arctic and North Atlantic oceans.
This could occur if global warming is sufficient to cause large scale melting of arctic sea ice and the Greenland ice sheet. Such a change in the current may be gradual (over centuries) or very rapid (over a few years). Either would cause planet wide changes in climate. This effect may be part of what starts and stops the ice ages. Global Warming Mapped. The world is getting warmer. Whether the cause is human activity or natural variability, thermometer readings all around the world have risen steadily since the beginning of the Industrial Revolution. According to an ongoing temperature analysis conducted by scientists at NASA’s Goddard Institute for Space Studies (GISS), the average global temperature on Earth has increased by about 0.8°Celsius (1.4°Fahrenheit) since 1880.

Groundwater pollution example in Lusaka, Zambia where the pit latrine in the background is pollulting the shallow well in the foreground Pollution can occur from landfills, naturally occurring arsenic, on-site sanitation systems or other point sources, such as petrol stations or leaking sewers.
Using contaminated ground water causes hazards to public health through poisoning or the spread of disease. Different mechanisms have influence on the transport of pollutants, e.g. diffusion, adsorption, precipitation, decay, in the groundwater. The interaction of groundwater contamination with surface waters is analyzed by use of hydrology transport models. Grand Canyon. View from the South Rim The Grand Canyon (Hopi: Ongtupqa; Yavapai: Wi:kaʼi:la) is a steep-sided canyon carved by the Colorado River in the United States in the state of Arizona.
It is contained within and managed by Grand Canyon National Park, the Hualapai Tribal Nation, and the Havasupai Tribe. President Theodore Roosevelt was a major proponent of preservation of the Grand Canyon area, and visited it on numerous occasions to hunt and enjoy the scenery. Great Barrier Reef. The Great Barrier Reef is the world's largest coral reef system composed of over 2,900 individual reefs and 900 islands stretching for over 2,300 kilometres (1,400 mi) over an area of approximately 344,400 square kilometres (133,000 sq mi). The reef is located in the Coral Sea, off the coast of Queensland, Australia. The Great Barrier Reef can be seen from outer space and is the world's biggest single structure made by living organisms. This reef structure is composed of and built by billions of tiny organisms, known as coral polyps. It supports a wide diversity of life and was selected as a World Heritage Site in 1981. CNN labeled it one of the seven natural wonders of the world. The Queensland National Trust named it a state icon of Queensland.
Murray–Darling basin. Map of the Murray–Darling basin Most of the 1,061,469 km2 (409,835 sq mi) basin is flat, low-lying and far inland, and receives little direct rainfall. NASA Visible Earth: Home. A ‘White Australia’ for the new national capital: Museum Victoria. The newly federated Australian government in 1901 quickly introduced national legislation to protect its security and assert its sense of identity as a member of the British Empire. The first act it passed was the 1901 Immigration Restriction Act. Known as the White Australia policy, the act restricted the entry of non-Europeans by means of a dictation test, which could be given in languages other than English. People suffering physical or mental diseases, convicted criminals, prostitutes and those reliant on charity, were also refused entry. Immigration Museum: Immigration Museum. Racism. No Way.: Fact Sheets: White Australia Policy.
