Answer:
animal wastes and fertilizers
Explanation:
The majority of the nitrates that are polluting the rivers come from the animal wastes and from the fertilizers used in the agriculture. The increased amounts of nitrates in the rivers causes eutrophication. This basically means that the water is becoming over-saturated with nutrients. This leads to the spreading out of the algae. As the algae spread out more and more, they cover the surface part of the water, so large portions of the rivers do not receive sunlight, which kills of the organisms that use photosynthesis. Further, the algae reduce the amount of oxygen in the water, often resulting in dying out of the fishes. It is a chain reaction that leads from one thing to another and the end result is devastating.
Answer: A. An explanation of the colors and symbols used on the map
Explanation:
Answer:
1. Endangered Species conservation
2. Air Pollution
3. Destruction of Coral Reefs
Explanation:
"Asia sits almost entirely in the tropics, and as such, is covered in rich, dense, biologically diverse jungle." Poachers, large companies exploiting land, small farms,(Etc), have always been a large factor of how hard it is to conserve the endangered species.
Small farms and large companies burn fires trying to clear land of trees(among other things.) So that then they can exploit the land the following year.
Over the past several decades, Asia's famous coral reefs have always been in dismay. This is the result of several factors like; 1. The ocean absorbs most of the carbon dioxide we put into the atmosphere each year. While this helps reduce the effects of global warming (temporarily), it also means that more of that carbon is going to be converted into carbonic acid, increasing the ocean’s acidity level.
