What are major types of freshwater systems and how have human activities affected them? and some examples Solution The major types of fresh water systems are 1 lentic: includes slow moving water example pools, ponds and lakes 2. Lotic: fast moving water like rivers and streams 3. Wetlands: these are the areas where the soil is saturated for atleast part of the time Humans from time immemorial have disrupted or affected fresh water sources 1. Humans have constructed dams and canals that caused fragmentation of large rivers. It destroys aquatic habitat by reducing water flow. 2. Agricultural run off and industrial effluent causes water pollution. Agricultural run off causes eutrophication of a water body that further leads to loss of biodiversity Minimata disease in Japan caused due to mercury poisoining is considered as one of the biggest examples of water pollution. 3. Inland wetlands are also being drained. For example more than half of inland wetlands in US in 1600\'s no longer exist..

1. What are major types of freshwater systems and how have human activities affected them?
and some examples
Solution
The major types of fresh water systems are
1 lentic: includes slow moving water example pools, ponds and lakes
2. Lotic: fast moving water like rivers and streams
3. Wetlands: these are the areas where the soil is saturated for atleast part of the time
Humans from time immemorial have disrupted or affected fresh water sources
1. Humans have constructed dams and canals that caused fragmentation of large rivers. It
destroys aquatic habitat by reducing water flow.
2. Agricultural run off and industrial effluent causes water pollution. Agricultural run off causes
eutrophication of a water body that further leads to loss of biodiversity
Minimata disease in Japan caused due to mercury poisoining is considered as one of the biggest
examples of water pollution.
3. Inland wetlands are also being drained. For example more than half of inland wetlands in US
in 1600's no longer exist.
