- Carbon levels in the atmosphere are set to break the 400 ppm (parts per million) mark. Sciences believe 350 ppm is the level at which carbon in the atmosphere begin to affect climates. At current level, we may be headed toward to wide-spread, drastic changes the Earth’s physical, biological, and chemical make-up.
- One major effect of increasing levels of atmospheric carbon is acidification of the world’s oceans. The increased acidity of oceans causes coral reefs to stop growing and eventually disintegrate. Coral reefs are key marine habitats which directly and indirectly support countless number of species.
- The world’s oceans are also the ‘world’s biggest garbage dump.’ 100 million tons of trash and debris is presently floating in a vortex near the surface at the center of the Pacific Ocean. The ‘Great Pacific Garbage Patch’ covers up to 5 million square miles. Another smaller floating patch of trash exists in the Atlantic Ocean. In these patches of debris, fine confetti-sized pieces of plastic float near the surface, break down further under the sun, and enter the oceanic food stream. Today, most sea food is too toxic for regular human consumption due to various pollutants.
- In the last century, the number of tigers in the wild has dropped from around 100,000 to between 1,500 and 3,500. It is estimated there are more captive tigers in Texas than exist in the wild today.
