Water Pollution
[ranking: 1]
Oil spills and radiation are rabid factors, as is chemical pollution based on human activity.
Industrial Waste
[ranking: 2]
Industrial waste is any solid waste that is produced by manufacturing or industrial processes.
Marine Trash
[ranking: 3]
The Great Pacific Garbage Patch is a huge chunk of collected debris and trash that's accumulated in the middle of the Pacific Ocean.
Air Pollution
[ranking: 4]
Smog, emissions from livestock, and carbon dioxide are all major contributors to air pollution worldwide. Air pollution can contribute to global warming and have detrimental effects on human health.
Endangered Species
[ranking: 5]
We're in the midst of the sixth mass extinction as species are dying off at an unprecedented rate. The loss of biodiversity can have powerful affects on our environment and be detrimental to human health.
Native Pollinators Threatened
[ranking: 6]
Habitat loss, disease and agro-chemicals are spurring the loss of native bees and other pollinators.
Waste Disposal
[ranking: 7]
Given our booming population, public waste companies can't keep up with demand for sanitary trash disposal.
Land Pollution
[ranking: 8]
If there's pollution in the soil, there's a risk of hazardous chemicals and toxicity in the agricultural growth in surrounding areas.
Littering
[ranking: 9]
Littering contributes to pollutions, increases toxins in soil and water, and can spread disease to humans and animals.
Ocean Acidification
[ranking: 10]
Since the beginning of the industrial revolution, there has been a 30% increase in ocean acidity.
Biodiversity Decrease
[ranking: 11]
Biodiversity helps our planet thrive, but certain human activities may be putting diversity at risk.
Overfishing
[ranking: 12]
In recent years, more fish have been caught than fish populations can replace through natural reproduction.
Overpopulation
[ranking: 13]
Human population is rising at a rapid rate and this means less space and resources are available. Does the earth have the capability to support human life given this record high number of people?
Radioactive Waste
[ranking: 14]
High-level radioactive waste - or nuclear waste - can take anywhere from 1,000 to 10,000 years to decay, and it remains hazardous this entire time.
Non-Recyclable Waste
[ranking: 15]
Non-recyclable materials mean bigger landfills, wasting the earth's valuable space, and chemicals in such materials can harm the air, water, and soil.
Global Warming
[ranking: 16]
NASA's 134-year record shows that 15 out of the 16 hottest years on record have occurred since the year 2000. Should we be doing more to curb manmade climate change? Reducing carbon emissions worldwide, and your personal carbon footprint, could help.
National Park Preservation
[ranking: 17]
Not only an environmental concern, but a cultural and historical one as well, how can we make sure our National Parks are preserved for future generations?
Greenhouse Effect
[ranking: 19]
Global warming, ozone depletion, and radiation all contribute to the Greenhouse Effect, which is warming up our planet to a dangerously high temperature.
Agricultural Pollution
[ranking: 20]
Agricultural pollution can result in human health deterioration, as well as severe ecological effects.
Eutrophication
[ranking: 23]
Eutrophication is the result of excessive nutrients or plant life in a body of water due to runoff from nearby land.
Desertification
[ranking: 24]
Certain practices in agriculture, deforestation, and changing weather patterns are resulting in once lush environments becoming increasingly barren.
Increased Natural Disasters
[ranking: 25]
Since 1980, there's been a serious increase in the amount of weather-related disasters that occur each year.
Monoculture
[ranking: 26]
Monoculture, or monocropping, is essentially weakening produce little by little over time by producing the same crop or livestock species in a single area.
