2. Seventy-eight percent of marine mammals die from getting entangled in plastic. Single-use bags and other plastic rubbish dumped in the ocean kill more than 100,000,000 sea animals annually.

3. Each year, Americans throw away around 25 billion styrofoam cups, which translates to about 82 cups per person.

4. Fungi are important organisms in the environment. They transfer nutrients from decomposing wood and leaf litter to aquatic systems, consume fossil fuel spills, and release important molecules into the soil.

5. In the United States, more than 10 billion paper bags are used annually, requiring the cutting down of 14 million trees.3

6. A glass bottle can take more than 1 million years to decompose or even more if it is in a landfill. A glass bottle manufactured and used 4,000 years ago may still be in the environment.

7. If you walk 1 kilometer along an average U.S. highway, you will see around 1,457 pieces of litter.

8. You can recycle paper from trees six times. After the sixth time, the paper’s fibers become too weak and cannot hold together.

9. The Great Pacific Garbage Patch is a ring of trash and waste.11 It covers approximately 1.6 million km2, an area thrice the size of France and twice the size of Texas, and contains around 100 million tons of rubbish.

10. An estimated 25 percent of coral reefs that adorn the world’s seas have been destroyed beyond repair due to:

  • Pollution
  • Overfishing
  • A warming climate
  • Mining coral for construction materials
  • Collecting live corals for aquariums and sea parks
  • Destructive fishing practices (using cyanide or dynamite)

10 Facts About Environmental Protection

There are numerous steps that individuals can take to protect the environment. These include:

11. Avoid buying single-use plastics

Whenever you are performing your day-to-day activities, carry a reusable bottle or flask in your bag. This cuts your weekly bottle buying and prevents bottles from ending up in oceans or landfills.9

12. Travel smart

If you can, carpool with friends, ride a bicycle, take public transport, or walk. This will reduce the number of cars on the road, which, in turn, reduces the emission of CO2.

13. Conserve resources

Conserve resources like electricity and water. Limit how you use them and do not be wasteful. You can do this by following these simple steps:

  • Insulate indoor areas
  • Fix leaking faucets and pipes
  • Use ceiling fans instead of air conditioners
  • Harvest rainwater and use it for day-to-day activities
  • Avoid hot water baths and shorten your shower time
  • Use LEDs instead of incandescent bulbs since they are more energy-efficient

14. Reduce your carbon footprint

As little as it may seem, your smallest efforts to reduce your carbon footprint make a huge difference.

On short journeys, walk or cycle instead of taking your car. You can also switch to green electricity, such as solar and wind energy, as they help reduce GHG emissions.

15. Plant pollinator-friendly plants

You can help pollinators by planting containers of nectar plants in your garden or front porch. Pollinators help create and maintain the ecosystems and habitats animals depend on for shelter and food.

16. Keep your garden chemical free.

Avoid using pesticides and herbicides. These substances kill moths, butterflies, and other pollinating insects, including beetles, ladybirds, and spiders.

17. Use reusable bags

Single-use plastic bags get disposed of and end up in landfills or oceans.

These can entangle marine life, leading to a slow, painful death. Moreover, single-use plastic bags take 1,000 years to degrade.

Wherever you go shopping, make sure to carry a reusable bag. Reusable bags cut down on litter, protect marine and wildlife, and decrease pollution and your plastic carbon footprint.

18. Plant trees

Planting trees is a great way to protect the environment. Increasing the number of trees helps reduce the carbon footprint.2 It also cleanses the air and improves air quality by absorbing CO2 and releasing oxygen.

19. Reduce, reuse, and recycle

  • Reducing involves cutting back the amount of trash you generate
  • Reuse involves finding new ways to use items you would have otherwise thrown away
  • Recycle involves turning old items (such as plastic containers) into new and useful items (such as recycling bins)

20. Air-dry your clothes

On sunny days, hang your clothes on a line instead of using a dryer. Not only will this leave your clothes smelling fresher, but it will also eliminate germs.

25. Pollution is the world’s number one killer, causing more premature deaths than cigarettes, terrorism, and natural disasters.

20 Facts About Climate Change

26. Thirty percent of human-made CO2 is absorbed by the ocean. As a result, the ocean water becomes more acidic, affecting marine life like plankton and coral and destroying the habitat of small fish.

27. The U.S. has 4.25 percent of the total global population and contributes to 28 percent of the world’s CO2 emissions.

28. Depending on the rate at which CO2 is dumped into the atmosphere, the global temperature is expected to rise from 1.1 degrees to 6.4 degrees by the end of this century.

29. Storms, floods, droughts, hurricanes, forest fires, and heat waves are some of the natural disasters resulting from climate change.

Destructive flooding as a result of climate change.


30. Climate change encourages the spread of pests that cause life-threatening diseases such as Lyme disease, dengue, and malaria, all of which can harm public health and cause population health issues, especially for vulnerable groups.12

31. CO2 is not the only gas that contributes to climate change. Other gasses like nitrous oxide and methane also contribute to climate change and are more dangerous than CO2.

32. As of July 2021, the concentration of CO2 in the atmosphere is the highest it has ever been.

33. The average sea level is expected to go up by at least a foot and eight feet by mid-century.6 Since 1880, the sea level has gone up by nine inches, and the rate is only accelerating.

39. Over the past five years, snow cover has drastically decreased, and the rate at which this is happening is expected to increase.14 Snow is reflective and helps regulate the earth’s internal temperature by reflecting the sun’s rays back into space.

Decreased snow cover leads to a decrease in drinking and irrigating water, dryer soil, and an increased risk of wildfire.

40. Glaciers are retreating in most global locations, including Africa, the Andes, Alaska, the Rockies, and the Himalayas.

41. The effects of climate change could potentially be irreversible. According to a report by the IPCC (Intergovernmental Panel on Climate Change), if urgent action is not taken, the catastrophic effects of climate change could be irreversible by 2030.

42. GHG levels are the highest they have ever been and are causing the global temperature to go up. Intensive farming, emissions from transport, and burning fossil fuels have all contributed to the rise in GHGs.

43. Usually, five species go extinct yearly; however, the world is losing between 10,000 and 100,000 species yearly. As more and more species go extinct, there will be a reduction in water quality, food security, and a loss of natural pest control.
