Threat Reading Answers Exclusive !full! — Earth Lakes Are Under
Pollution is another major threat to lakes. Industrial and agricultural activities have led to an increase in pollutants such as fertilizers, pesticides, and heavy metals in lake waters. This has resulted in the degradation of water quality, harming aquatic life and affecting human health. For example, Lake Baikal in Russia, the world's largest and deepest freshwater lake, is facing pollution from sewage, industrial waste, and agricultural runoff.
Lakes provide about 20% of the world's freshwater supply.

Implementing sustainable agricultural practices, such as drip irrigation, can drastically reduce water consumption [1]. Pollution is another major threat to lakes
Deforestation and urbanization increase sedimentation. Sediments fill in lake basins, reducing their capacity and often transporting pollutants into the water ecosystem [2]. The Broader Ecological and Human Impact
In some cases, it can be a challenge for scientists to predict outcomes for a lake or to recognise the factors that threaten it. Take, for example, Lake Waiau in Hawaii, a lake that was used in healing rituals by native Hawaiians. It is a fairly small lake, approximately 100m across, with some variation as the water level rises and falls. However, in early 2010, the lake began to decrease in size. By September 2013, it could only be described as a pond. The cause of the lake’s decline has not yet been established, but drought is among the suspects. Then there is Scott Lake in central Florida. In June 2006 a massive sinkhole opened up beneath the lake – acting like a plug hole in a bath. It only took two weeks for the water to drain away. Local residents called meetings to decide what action to take, but in the end, nature took care of the problem. Clay, sand and other fine material plugged the hole and the lake started to fill with water again. Nevertheless, as geologists point out, sinkholes can occur with some frequency in Florida, so there is a chance that Scott Lake will drain away again. For example, Lake Baikal in Russia, the world's
Here are the official answers to the reading passage, complete with detailed explanations that show exactly where each answer can be found in the text and why it is correct.
Focus here is often on invasive species and chemical runoff management. Conclusion: A Global Call to Action
The primary cause of shrinking lakes is human demand for water. Excessive water diversion for agriculture, industrial processes, and domestic consumption directly lowers water levels [1].
