Species diversity in the world's seas Species diversity in the world's seas
The graphic compares the amount of diversity of marine mammals, sharks, molluscs, birds, shrimp and lobsters in various sea regions. Coral reefs are among the most productive and diverse of all natural ecosystems. Recent decades have been catastrophic for them, however; some 10% of the world’s reefs may already have been degraded beyond recovery, and another 30% are in decline. Meanwhile biologically rich coastal wetlands, including mangrove fore...

Probability of gastroenteritis amongst bathers exposed to increasing faecal streptococci densities from samples taken at chest depth Probability of gastroenteritis amongst bathers exposed to increasing faecal streptococci densities from samples taken at chest depth
The graphic shows the probability of aquiring gastroenteritis when bathing in water containing faecal contaminants. Gastroenteritis is the irritation and inflammation of the digestive tract. This condition may cause abdominal pain, vomiting and diarrhea. Severe cases of gastroenteritis can result in dehydration.

World coal consumption World coal consumption
The graphic shows the world coal consumption from various regions in comparison to the world totals. It shows trends from 1990 to 1999 and predicts the patterns to 2020. The predictions to 2020 show a decrease in coal consumption in eastern Europe and the former Soviet Ùion. However, it shows a considerable increase in the North America and developing countries, causing the total global consumption to increase.

Emissions of CO2 per capita 1990 (selected countries) Emissions of CO2 per capita 1990 (selected countries)
The graph shows emissions of CO2 per capita 1990. CO2 can be emitted as byproduct from the use of fossil fuel, by combustion, land-use conversion and cement production. Atmospheric concentrations of CO2 are increasing, and it is indicated that this contributes to global warming and climate change.

Global CFC production Global CFC production
Chlorofluorocarbons (CFCs), along with other chlorine- and bromine-containing compounds, have been implicated in the accelerated depletion of ozone in the Earth's stratosphere. CFCs were developed in the early 1930s and are used in a variety of industrial, commercial, and household applications.

Global fertilizer consumption Global fertilizer consumption
In recent years, there has been concern that the quantity of mineral fertilizers used in agriculture having adverse effects on the environment. Attention has been drawn to the fact that when nutrients are applied to crops they are not all taken up by the plants immediately. There is also concern that some farmers might be applying inappropriate quantities of fertilizer. The main fertilizers having adverse effects on the environment are nitrate, p...

Global atmospheric concentration of CO2 1870-1990 Global atmospheric concentration of CO2 1870-1990
Historically the developed countries of the world have emitted most of the anthropogenic greenhouse gases. The U.S. emits most in total, and is one of the countries with highest emissions per capita. China is the second largest emitter, but has very low emissions per capita. Over the last 20 years, industrial development has led to a rapid rise in the volume of emissions from Asia, but on a per capita basis, emissions in this region are still at ...

Regional alkalinity trends Regional alkalinity trends
Measuring alkalinity determins a stream's ability to neutralize acidic pollution from rainfall or wastewater. Alkalinity refers to the ability of water to resist change in pH. The graphic shows global comparison of alkalinity measured in milligrams per litre, for the years 1976 and 2000.

The graphic shows the trend of the number of harmful algal blooms in the Western Atlantic from 1970 to 1996. The excess growth of algae is often caused by pollution, and can have negative or fatal effects on some species of fish.

Sites with dead zones (oxygen depletion on the sea bottom) Sites with dead zones (oxygen depletion on the sea bottom)
Dead zones (hypoxic i.e. oxygen deficient water) in the coastal zones are increasing, typically surrounding major industrial and agricultural centers. This is commonly occuring due to nutrient pollution, in the form of nitrogen and phosphorous leading to algal blooms and eutrophication

Each of the big five stressors (not in order of magnitude), 1) Climate change; 2) Pollution (mainly coastal), 3) Fragmentation and habitat loss (from e.g. dredging/trawling, use of explosives in fishing on coral reefs etc.), 4) Invasive species infestations, and 5) Over-harvest from fisheries may individually or combined result in severe impacts on the biological production of the worlds oceans and the services they provide to billions of people ...

Tropical sea temperature rises and coral reefs - climate change scenarios Tropical sea temperature rises and coral reefs - climate change scenarios
The impacts of coral reefs from rising sea temperatures. When coral reefs become heat-exposed they die, leaving the white dead coral, also known as bleaching. With even moderate pollution, the coral are easily overgrown with algae, or broken down by wave activity or storms, leaving only “coral rubble” on the ocean bed.

Invasive species in the marine environment - problem regions Invasive species in the marine environment - problem regions
The locations of major problem areas for invasive species infestations or occurrence of exotic species in the marine environment. The impacted areas are concurrent with the areas subjected to the worst pollution, the most intensive fisheries and bottom trawling, and major shipping routes. The areas in the figure have been highlighted based on an overview of literature, and the delineation of the areas are approximate.
