The Current State of Water Pollution
One of the most differentiating factors of the planet Earth is the abundant presence of water. The Earth is almost 75% water. The substantial amount of water on the planet allows the vast and diverse biotic population to thrive. Without water, none of the life on the planet would be living, Earth would look less green and blue, and more dry like Venus or Mars. However, one of the most prominent environmental epidemics is the pollution of the Earth’s water bodies. According to the WWF, water pollution is characterized by “toxic substances” entering water bodies, and then “getting dissolved in them, lying suspended in the water or depositing on the bed

Water Pollution
When the water in our rivers, lakes, and oceans becomes polluted it can endanger
wildlife, make our drinking water unsafe, and threaten the waters where we swim and
fish. Some people believe that the pollution of our lakes and rivers is not a problem right
now and is a problem for the future that modern technology will be able to fix, wrong.
According to P. K. Goel author of the book Water Pollution: Causes, Effects and Control,
“Most of the wastewater, statistics indicate around 60% of it, is discharged into rivers
without being treated” (Goel). This is a high pollution of the environment and also a big
health risk to the people who rely on the water downstream. Water

As earth’s temperatures continue to become more extreme due to global warming (extremely hot summers and cold winters), our agricultural practices are endangered. Many plants and animals rely on certain weather conditions to thrive, and global warming has resulted in the loss of many crops and animals. Most crops, such as wheat, corn, and soy have what's known as an “optimal growth temperature”, meaning that they thrive under a certain temperature range. When the temperatures exceeds or fails to meet these temperatures for extended period of time, mass crop death can result. This is harmful because it not only leads to more expensive food prices, but can

For example, trees are being cut down for industrial reasons and a lot of factories are replacing forest gradually; these results in high concentration of toxic gases in the air. Furthermore, the human population keeps growing and is growing quickly, but trees are being cut down every day; this imbalance creates more carbon dioxide and less oxygen. Carbon dioxide is the gas that has negative effects to our atmosphere and increases the greenhouse effect.
