Answer 1

See ref below

Answer 2

FIRSTHAND CONTAMINATION

Rivers and Lagoons

millions of batteries are thrown in the rivers and Lagoons by night fishermen

1 small penlight battery contaminate 10.000 litres of water

raw sewage added to water flows like cannals and rivers ,

trash dumped on rivers edges ,

Industry contaminates practically unchecked

farmers using agro chemicals (fertilizers ,herbicides & pesticides)then deforrest and the rains washing the topsoils impregnated with contaminants into the rivers

thousands of women that do the washing in rivers using harmfull detergents.

farmers dump acidic coffee husk into the waters which kills millions of fish ,

on the coasts

oil spills that contaminate coastal waters,

Oceans

industrial wastes that are dumped into deep oceanic trenches

SECONDARY POLUTION

changes in water temperature enhances harmfull algae,(remember the red tide)

and kills many fish who are critical to temperature ,when sea water enters lagoons here in Mexico many fish die ,due to sudden temperature changes

also warm water releases carbon gasses

cold water absorbs them

SOLUTIONS

wetlands like swamps have always been Natures natural filters for natural water flows,aquatic plants clean the water ,the anchored plants as well as the floating ones

we should redesign wetland flora with in natural water systems to help contra contamination.

stop sewage systems that connect to natural water flows ,forbid and police the dumping of rubbish on waters edges ,

the best way is through the educational systems ,starting at kiddy schools and rising in intensity with progression.

but in Mexico this is not accepted because this kind of education is not in the ciriculum.

In short the ways to protect the waters is

laws and punishment ,government vigilence ,education ,

alternative farming methods away from using chemicals ,which eventually end up in the ground water supplies

to merely clean polution or try to clean is never effective because of population growth ,it gets worse by the year ,an impossible task

we must attack at the roots and that is the contaminating mentality
