world nothing, and wherever there is no clean water, no river, they hear a gate with dirty water. this happens in the hall, vietnam, and madonna, any of the world health organization has reported on me the real problem to irrigate with untreated wastewater. the, although not all of the entities he has problems have been solved, these scientists are making strides. ah, they progress gives reason for hope. ah, ah, still the world's growing population needs more than fruits and vegetables. fish also in demand with more and more being found. in fact, we already can few more fish from aquaculture than from fisheries.

many environmentalists criticized fish bombing because of the fish species and antibiotic, but in the polluting surrounding water and ecosystems. but agriculture doesn't have to be so destructive they don't yana national park and stuff. question thing is a critical wickland made up of pine grove, marshland, and teens. it's also a stop over for my grocery bird. domingos. lead us to a spot beside the park of fish near the mouth of the river. what l. chavira, i use this irrigation channel delivered water from the river to the farm, which is the size, the full and a half 1000 soccer fields. the scale of the formation suggests

proposed fish farming. over all people eat more species of fish and the food of land based animals. worldwide we breed more than $600.00 aquatic creatures, including sea, cucumbers and jelly fish versus about $38.00 species of land animals such as canceled chickens and pay awe here at the fish from hardly any fish extra meant remains. it's been removed by natural mean clowns on the banks here full to the water, so it can flow more cleanly back into the river. so beds the foam has become red page. the national park next door is very dry and he has stomach. but here is nourishment and water for about $250.00 different species,

that means the old plans being modernized, well, new ones are being built the ought to be 5 in total to treat the waste water from factories, offices, and homes across the region with the population of more than 2000000. at the same time, the river is being re natured, flood plains are being created to take in the water. when the overflows the banks it's already looking a lot better, and some animals are coming back and birds,
